TO: OIM / ET Group

SUBJECT: Differential Combo System

Please note that you are receiving the Shell specific Differential Combo System that includes the

following items:

1. Liquid Seal Pressure Gauge (LSP) w/ pressure sensor (G1 / T1)

2. Mud Gas Separator Pressure Gauge (MGS) w/ pressure sensor (G3 / T3)

3. Mud Gas Separator Temperature Gauge w/ temperature sensor (G4 / T4)

4. Differential Gauge LCD (G2 / no applicable T sensor, differential module in jbx)

5. Junction Box with preinstalled mating cables for plug and play installation

6. Four Gauge Mounting bracket for above items 1-4.

7. Interconnect cables as specified by your rig

In order to simplify installation, please review the enclosed General Assembly drawing which has

identified the Gauges as (G#) and corresponding sensors (transducers) as (T#). Items 1-3 above will

have a reference G# along with a T# and these items have been color coded with electrical tape

around the sensor 2’ cable and gauge case ring to ensure you have matched the corresponding units

together.

As part of our deliverables, each low pressure gauge systems (MGS & LSP) is configured with a 1”

NPT housing with a corresponding 2” 300 # ANSI and a ball valve which will allow you to isolate the

pressure sensor as needed in the future to service the unit. Signal cables as provided to the rig are also

included and come preinstalled with M/F connectors for quick plug and play set up.

The overall system is configured that the MGS and LSP Systems have a 4-20mA Output that is

terminated into a Differential Module that provides a 4-20mA Output to the Differential LCD

Assembly input side to display the value as (Liquid Seal Pressure – MGS Pressure). The Differential

Gauge is configured with an additional 4-20mA Output which can be taken into another system if so

desired at a later date to have the unit feed your drilling chair’s or another system.

Please note the main signal cables may not have been specifically identified at the time of order as to

which is for the MGS, LSP or MGS Temperature, but all Inline cables comes preinstalled with a 5

Socket Inline and a 5 Pin Terminator and are interchangeable. Once you confirm which cable is

which, it is suggested that you confirm the cable markings as the pressure sensors are pre-calibrated to

the gauge and crossing the cables to different units will generate inaccurate and sometimes strange

results. Note: the shorter 4-20mA signal cables are slightly different.

When routing the cables, please note one end will have 90° connectors which will be the side

connecting to the gauges in the 4 gauge bracket. It is suggested that you start from the gauge side

and connect the cables and when mounting the bracket and allow yourself future access for

serviceability as the units will require battery replacement approximately every 18 months.

If you wish, the gauge arrangement can be re-organized to meet your orientation as the gauge ID tags

can be removed along with the gauges to best suit your needs.

Note: As you are looking at the gauge LCD’s, the left side is considered the input side coming from

the sensors and the right side is the 4-20mA signal that will terminate to the junction box.

In order to complete the full installation, the following items will need to be completed by the rig:

1. Determine location of Junction box for installation. Mounting details are included in drawing

packet.

2. Determine location of 4 Gauge Bracket and confirm if Horizontal or Vertical mounting is

desired and if necessary adjust ID tags and gauge orientation. Mounting details included.

3. Verify Inbound power supply cable has been routed to Jbox location and appropriate cable

gland is available. Power supply can be either 110 or 220VAC.

Complete wiring termination into the Junction box to the Phoenix power supply as noted. Verify

before supplying live power see Figure 1 below. NOTE: T1 connects to G1A and then to G1B.

Repeat for remaining cables.

Note: The MGS Temperature has a 4-20mA output signal that can be picked up for use if so desired

from the junction box via the remaining spare gland entry.

Figure: 1

Please note, we have included a few drawing packets as there are several available options and ask

that you review the applicable packet specific to your rig. Ex: Horizontal versus Vertical mounting of

the gauge bracket or AC versus DC inbound power sources as shown under Option A above.

If you have any questions, please feel free to contact our office.

SECTION 1 Introduction:

1.1 Forward:

The Houston Digital Instruments, Inc. (HDI) 2000B and 2000P Series are designed to combine laboratory accuracy, repeatability, and withstand the rigors of the oil field environment. The 2000B and 2000P share a technology legacy that dates back to 1988 when HDI first introduced battery powered, intrinsically safe instrumentation to the industry.

The HDI Model 2000B is a direct replacement for most 6” diameter panel mounted gauge hydraulic systems with either a four-bolt (90°) or a three-bolt (120°) mounting pattern. The HDI Model 2000P directly replaces hydraulic standpipe (i.e. Parking Meter) style gauges.

This manual describes the installation, operation, maintenance and calibration of the HDI 2000 B/P Pressure Gauge Systems. This manual provides the user with information necessary to properly and fully utilize the instrument. Included within are all the necessary procedures to install and maintain this instrument properly.

1.1.1 Unpacking and Inspection:

Upon receipt of the equipment, please verify that all of the items are accounted for on the packing list. If any items are missing, immediately inform the Freight Forwarder. Inspect all items for damage. If any items are damaged, immediately inform the Freight Forwarder and Houston Digital Instruments, Inc.

1.1.2 Precautionary Information:

Please follow all directions when unpacking and handling this equipment.

SECTION 2 System Description:

2.1 System Description:

The HDI 2000 B/P Series Pressure Gauges are battery powered, stand alone and intrinsically safe electronic pressure gauge systems. The gauge system is designed to measure the applied force exerted upon the sensor (pill) face of the HDI Pressure Transducer. The 2000 B/P gauge will work only with the proper HDI Transducer and will not work with other vendor’s transducers.

CAUTION: Connection to non-HDI supplied transducers could damage the internal circuitry of the Gauge Control Head.

The HDI 2000 B/P Series Pressure Gauges are shipped as matched and calibrated systems, comprised of the gauge head and transducer. The Gauge/Control head and transducer are serialized and matched as a set. Once calibrated, the gauge and the sensor become a matched pair.

ACCURACY: The HDI 2000 B/P are factory calibrated to measure and display the applied pressure to a tolerance of 0.5 (1/2) percent Full Scale (FS). The factory calibration is performed with a NIST traceable Pressure Standard, and each Gauge system is shipped with the signed and witnessed Factory Calibration Test Sheets. All Factory Calibration is performed in PSI regardless of final Engineering Unit Selection. Once calibrated, the gauge and the sensor become a matched pair. The substitution of any component, including wire / cable, requires a recalibration of the system.

The HDI 2000 B/P Gauge’s Control Head is comprised of a liquid crystal display (LCD) display that includes both a numeric (5 digits) representation (for accuracy) and a bar-graph (101 segments) representation (for trend) and battery low alarm indicator.

The HDI 2000 B/P may be supplied with a range of transducer options. These include: 6000 PSI, 10000 PSI, and 16000 PSI transducers mounted in a variety of Process connections that include 1502 WECO, 2202 WECO, 2” Line Thread, as well as a variety of ANSI and API Flange. Please refer to the model matrix in section 2.2.1 for details.

2.3 System Options:

Custom designed systems will include, per the customers' request or customers' specifications, certain options required to meet offshore area classifications or specific customer requirements. Each system of this type will be designed to meet specific requirements or classifications and is therefore unique. As such, these custom options go beyond the scope of this publication. Please see specific instructions on the use of custom options (if applicable). Standard options include:

2.3.1 4/20 mA Output:

HDI offers as an option, a signal current loop providing a 4/20 mA remote output that may be used for chart recorder inputs and/or data logging. This option requires that the 4/20 mA Current loop be externally powered. This is a factory-installed option and field calibration is unnecessary.

2.3.2 0-1 V-dc Output:

HDI offers as an option, a signal current loop providing a 0-1 V-dc remote output that may be used for chart recorder inputs and/or data logging. This is a factory installed option and does not require calibration

2.3.3 Remote/Slave Gauge Display:

SECTION 3 Installation:

3.1 Components:

3.1.1 Pressure Gauge and Transducer:

The pressure gauge and transducer are to be mounted by the customer at the locations deemed most suitable for such equipment.

3.1.2 Cables:

Standard cable length is 50'. Maximum recommended cable length is 200'. Cable lengths can exceed this recommendation, however this may have an impact on gauge operation. Cable lengths from the transducers to the gauge, other than standard, may be requested and supplied by HDI. Specific requests should be supplied at the time of order entry. Interconnecting cable shall be installed using acceptable standards for such installations.

3.2 Mounting Components (Model 2000B):

3.2.1 Pressure Gauge:

The pressure system gauge is designed to be installed in the standard 6" cutout hole in the panel. Both the 90-degree and 120-degree bolt patterns are designed into the gauge and all applicable mounting hardware is included with the system. Remove the #10 elastic stop-nuts from the 10 X 32 screws, drop the gauge in the appropriate hole and replace the stop-nuts.

Caution: Do not over tighten stop-nuts

3.2.2 Pressure Transducer:

Refer to the Pressure Transducer’s specifications for mounting instructions.

CAUTION: Special care should be taken to insure that the transducer pill mounted in the center of the transducer housing, is not allowed to make contact with any hard and/or sharp object as the transducer pill is vulnerable to this type of contact and the accuracy and the sensitivity could be affected.

3.2.3 Cables and Cable Routing:

The transducer to gauge head cable (harness) comes as part of the system, and is properly mounted and routed within the Yoke Assembly. No customer or user input or action is required. Optional Output Cables must adhere to HDI specifications and only HDI specified cables are to be used to interconnect the Pressure Gauge assembly to other systems. Industry standards for the routing of such cables (to include minimum bend radii) must be adhered to, with special attention paid to the routing of the


8

transducer signal cable in close proximity to high voltage and/or high current cables. If such routing is required, then the HDI signal cable must be routed at least 6” from the high voltage cable for any parallel route length that exceeds three feet in length.

3.3 Mounting Components (Model 2000P):

3.3.1 Pressure Gauge and Transducer Assembly:

The HDI Model 20XXP is a modular assembly that includes the Pressure Gauge head and Transducer mounted in a “Yoke” Assembly. To install the system, the Gauge head shall be removed from the Yoke assembly by removing the two 10X32 bolts and stop-nuts, then carefully lifting the gauge head from the Yoke cradle. Located under the bottom center of the Gauge head, there is a Cannon / Bendix ¼ turn connector that connects the gauge electronics to the transducer wiring harness. Disconnect the cable from the gauge head and place the gauge head aside. Care must be taken to prevent water or other debris from getting into the yoke assembly while the gauge head is removed.

The Transducer assembly (with Yoke) may then be installed onto the pressure port. Refer to the Pressure Transducer’s specifications for mounting instructions.

Caution: Special care should be taken to insure that the transducer pill mounted in the center of the transducer housing, is not allowed to make contact with any hard and/or sharp object as the transducer pill is vulnerable to this type of contact and the accuracy and the sensitivity could be affected.

Once the Transducer/Yoke assembly has been securely mounted, the gauge head can be re-installed into the Yoke Cradle. This accomplished by following the removal process, but in reverse order. First re-connect the Canon/Bendix ¼ turn connector, and then mount the gauge head into the cradle. Finally, re-install and tighten the 10X32 bolts and stop-nuts.

Caution: Do not over tighten the stop-nuts

3.3.2 Cables and Cable Routing:

The transducer to gauge head cable (harness) comes as part of the system, and is properly mounted and routed within the Yoke Assembly. No customer or user input or action is required. Optional Output Cables must adhere to HDI specifications and only HDI specified cables are to be used to interconnect the Pressure Gauge assembly to other systems. Industry standards for the routing of such cables (to include minimum bend radii) must be adhered to, with special attention paid to the routing of the transducer signal cable in close proximity to high voltage and/or high current cables. If such routing is required, then the HDI signal cable must be routed at least 6” from the high voltage cable for any parallel route length that exceeds three feet in length.

SECTION 4 Theory of Operation:

4.1 Pressure Gauge System: The major components of this system are the gauge head assembly, the pressure transducer assembly, cabling, and in the case of a HDI2000P, the Yoke/cradle assembly. The gauge head assembly contains its own internal power supply in the form of an “intrinsically safe” EXIA approved, 3.6 V dc, replaceable battery pack. This battery pack provides the power to run the internal circuitry of the gauge assembly, including its display, micro-controller, and transducer excitation and sensing circuitry. The internal battery does not provide the power to drive the 4-20 mA loop (if so equipped). The pressure gauge system requires minimal power during normal operation. The gauge is designed for continuous operation, but can be turned off by the user if desired. The gauge will retain its calibration information while off. The battery life is guaranteed for one (1) year of continuous operation, typical battery life is approximately 18 months.

The gauge assembly excites the transducer with a constant current source and measures the output voltage of the transducer. Typically the full-scale output voltage is about 100mV DC. It is therefore important to pay close attention to cable routing as to avoid spurious noise sources that may impact gauge operation. The internal analog to digital (A to D) circuitry converts the analog voltage input signal to a digital (16 bit) source that is in turn read by the gauge system’s micro-controller. The micro-controller performs the math based upon the factory/field calibrations, and scaling inputs to drive the display circuitry, and optional output circuitry. Calibration and field settable options are stored in internal E2Prom (Electronically Erasable Programmable Read Only Memory), and are retained during power off periods, such as transport or battery replacement. Upon Power-up of the Gauge assembly, the micro-controller interrogates the E2Prom, and uses this information in setting the runtime variables of the gauge operation. The user can change the calibration, settings, and therefore change the data stored in the E2Prom at any time. The user can also clear the E2Prom, and start from the factory configuration.

SECTION 5 Operations: 5.1 Gauge Head Features:

As shown in the above figure, the Gauge head has several distinctive features or sections features or aspects that this manual will explain in detail: 5.1.1 ENG UNITS DISPLAY: The Engineering Units Display normally (Normal RUN Mode) indicates or displays the Engineering Unit of Measure that the pressure readout is measured in (i.e. BAR, PSI, KPA). In other operating modes, this display indicates the name of the mode that the gauge is currently in 5.1.2 MAIN DISPLAY: The Main Display normally (Normal RUN Mode) displays in numerical format, the measured pressure. The displayed pressure is in the unit of measure as indicated in the ENG UNITS DISPLAY. In other operating modes, such as “SERIAL NUM”, this unit will display other pertinent information to the user/operator.


11

5.1.3 BAR GRAPH DISPLAY: In all operating modes, in which the bar graph is active, the Bar Graph Display will indicate the relative pressure as a scale (or percentage) of full scale. The Bar Graph Display is divided into 101 segments, with each segment representing 1% of full scale. In addition, the Bar Graph area of the LCD display is silk-screened with a scalar graph of the indicated range. 5.1.4 LOW RANGE DISPLAY: In all operating modes, this display indicates or displays the low (or Zero) range of the Pressure Gauge system.

5.1.5 HIGH RANGE DISPLAY: In all operating modes, this display indicates or displays the Full Scale (or Span) range of the Pressure Gauge system

5.1.6 POWER ON/OFF BUTTON: The Power ON/OFF Button is part of the Front Face Button panel, and is a momentary contact switch. There is a tactile feel to the depressing and releasing of the buttons. The Power On/Off Button is used to turn on or off the gauge. If the gauge is OFF, depressing and releasing the button, will turn the gauge ON. If the gauge is ON, then the opposite occurs. 5.1.7 MODE BUTTON The Mode Button is part of the Front Face Button panel, and is a momentary contact switch. There is a tactile feel to the depressing and releasing of the buttons. The Mode Button is used to cycle through the different operating modes of the gauge system. In Normal Run mode, this button has no effect on operation. 5.1.8 UP BUTTON The Up Button is part of the Front Face Button panel, and is a momentary contact switch. There is a tactile feel to the depressing and releasing of the buttons. The Up Button is used to cycle through certain settings within the configuration and calibration modes of the Gauge head. . In Normal Run mode, this button has no effect on operation.


12

5.1.9 DOWN BUTTON The Down Button is part of the Front Face Button panel, and is a momentary contact switch. There is a tactile feel to the depressing and releasing of the buttons. The Down Button is used to cycle through certain settings within the configuration and calibration modes of the Gauge head. . In Normal Run mode, this button has no effect on operation.

5.1.10 ENTER BUTTON The Down Button is part of the Front Face Button panel, and is a momentary contact switch. There is a tactile feel to the depressing and releasing of the buttons. The Enter Button is used to either select a config/calibrate mode or to confirm selection of user-entered data or settings.

5.2 Operating Modes

The HDI 2000 B/P Series of Gauges have three operational modes contained within the firmware. One mode is for factory use only and is not accessible from the field. In rare cases, an HDI technician may instruct a user on how to enter and operate this mode, but for the purposes of this manual, this mode (factory) will not be discussed.

5.2.1 NORMAL RUN MODE In “Normal RUN” Mode, the gauge will excite the transducer and display the measured pressure on the Main display. The Gauge will display the current Engineering Units in the ENG UNITS Display, and the Bar-graph will be active. The de-pressing and/or releasing of the MODE, UP, DOWN, and/or ENTER buttons will have no effect while in this mode. To enter into the Normal RUN Mode:

Insure that the Gauge head is OFF. If the Gauge Head is ON (regardless of operating mode), de-press and release the Power Button once. This action will turn off the gauge head.

De-press and release the Power Button once, from the OFF state, this will activate (turn ON) the gauge head, and the gauge will enter Normal Run mode automatically.


13

5.2.2 CONFIG / CAL MODE The “CONFIG / CAL” mode is used to view, determine, or set certain configuration and calibration characteristics of the gauge system. There are several layers (sub-modes) contained within this mode, and dependent upon which sub-mode, the gauge is in, determines the output on the gauge LCD as well as the interaction of user input from the button panel. Care must be taken when operating in this mode, for it may be possible to inadvertently change some operating characteristic that will cause the gauge to operate incorrectly, and thus provide the user with incorrect pressure readings. To enter into the CONFIG/CAL mode:

Insure that the Gauge head is OFF. If the Gauge Head is ON (regardless of operating mode), de-press and release the Power Button once. This action will turn off the gauge head.

De-press and hold the “MODE” Button, and then de-press and release the Power Button once from the OFF state, this will activate (turn ON) the gauge head. Once the gauge has started the POST, release the “MODE” button. The gauge will enter the first of the CONFIG/CAL sub-modes, namely the “Display Serial Number” sub-mode.

By de-pressing and releasing the MODE button, the user can cycle through the different sub-modes within the CONFIG/CAL Mode.

5.2.2.1 Display Serial Number Sub-mode HDI keeps records on all the products it ships, and these records are filed by the serial number of the system. These records include date of build, options installed, as well as any service history. This sub-mode gives the user instant access to the serial number, thus providing the user and HDI with enhanced and prompt response to any service and operations issues. In this sub-mode, the ENG UNITS DISPLAY, will display “SERN”, and the MAIN DISPLAY will display the five-digit Serial Number. The Bar Graph is disabled, and no measurements are processed. There is no user action in this sub-mode. 5.2.2.2 Calibration Sub-Modes Unlike all previous HDI Pressure Gauge systems, the HDI20XXB/P Gauge systems are electronically calibrated from the front panel. That means that the user does not have to open-up the case and adjust potentiometers. The gauge systems are calibrated at the factory, and the gauges should not need any adjustments to this calibration for at least one year (or greater), but in the extreme cases of system failure, transducer replacement, etc., the gauges can be field calibrated.


14

5.2.2.3 Calibrate Low Range (ZERO) Sub-mode The Calibrate Low Range (ZERO) sub-mode is used to re-calibrate the zero set point of the gauge system. To enter this mode:

From the “Display Serial Number” sub-mode, de-press and release the MODE BUTTON. The ENG UNITS DISPLAY will change to a display of “ZERO”, the Main display will display the zero-set point (typically 00000) as stored in E2Prom. The Bar Graph is inactive in this mode.

Ensure that the Gauge is properly connected to the transducer/cable, and that 0 PSI is applied to the pressure transducer.

Using a test pressure gauge, attached to the same pressure source, verify that 0 PSI is applied and the test gauge displays zero.

If in the event that some residue pressure (not to exceed 30 PSI) is in the system, then by using the UP and DOWN BUTTONS, adjust the ZERO set point of the HDI20XXB/P to match the residue pressure reading of the test gauge.

Once the Pressure readings match, confirm and store the zero set point into the HDI20XXB/P E2Prom, by de-pressing and releasing the ENTER BUTTON.

5.2.2.4 Calibrate High Range (SPAN) Sub-mode The Calibrate Low Range (ZERO) sub-mode is used to re-calibrate the Span or High set point of the gauge system. To enter this mode:

From the “Display Serial Number” sub-mode, de-press and release the MODE BUTTON. The ENG UNITS DISPLAY will change to a display of “ZERO”. De-press and release the MODE BUTTON once more, the ENG UNITS DISPLAY will change to a display of “SPAN”. The Main display will display the Span-set point (typically full scale of gauge) as stored in E2Prom. The Bar Graph is inactive in this mode.

Ensure that the Gauge is properly connected to the transducer/cable

Using a test pressure gauge, attached to the same pressure source, verify that 0 PSI is applied and the test gauge displays zero.

Pressurize the system to the full scale rating of the gauge head. Caution must be taken as not to over-pressurize either the HDI20XXB/P or the test gauge.

The test system must be able to pressurize and hold pressure to at least 85% of the HDI20XXB/P full-scale rating.


15

If in the event that the test system cannot pressurize the system to the full-scale pressure, there is an option to calibrate the system below full scale. By using the UP and DOWN BUTTONS, adjust the SPAN set point of the HDI20XXB/P to match the pressure reading of the test gauge.

Once the Pressure readings match, confirm and store the zero set point into the HDI20XXB/P E2Prom, by de-pressing and releasing the ENTER BUTTON.

Please be advised, that the gauge calibration is now based upon this new setting, and HDI will not guarantee the accuracy of this gauge to meet HDI’s published specs.

Section 6 Battery Replacement 6.1 Battery Replacement

In order to replace the battery, it is first necessary to remove the screws attaching the ring surrounding the gauge face. Remove the ring. Supporting the gauge face with the palm of the hand, turn the assembly face down and lift the gauge housing away from the face. Install the replacement battery and secure in place using the supplied ty-wraps. Reconnect the battery and leads and re-assemble the gauge.

APPENDIX C Calibration Summary

Quick Introduction to Button function Operation:

With the gauge turned off, hold the “M” button and power on the gauge. Release the “M” button once the display lights up. Once the POST is complete hit the “M” button again and at the bottom of the LCD, the “PSIG” will change to show serial #, press “M” again it will show you “Lo Cal” and press “M” again and “Hi Cal” will display. Note: Write down what the default “Hi Cal” set point is for your records. If at all possible, we would like for you to use this set point for future gauge calibrations but understand this may not always be possible.

To begin:

Start with the gauge display turned off, transducer connected to the gauge and no pressure on the system. If you have a 2” 1502 / or 2” 2202 knock the connection loose to ensure there is no static pressure. You must also be prepared to supply at minimum 50% of the gauge pressure range for final calibration.

1. Hold the “M” button and power on the gauge. Once the POST test begins, release

the “M” button.

2. Next is to toggle thru the “M” options to access the preset factory calibration points.

3. Press the “M” button and the display will show the gauge serial #.

4. Press the “M” button again, the “Lo Cal” set point will display. This by default will be Zero (0).

5. If you have no pressure, Press the “E” (enter) button to accept this set point. Note: The gauge will return to PSIG. Press the “M” button to enter back into Calibration mode.

6. In order to proceed to the “Hi Cal”, you must be able to pressure to 50% of the gauge pressure range, i.e. 16K would require min 8K PSI. Go ahead and pressure the device.

7. Press “M” again to access the “Hi Cal” set point and once you have stabilized pressure, Press “E” and if it is accepted / stored – the bar graph display should instantly kick up to the applied pressure currently on the gauge. Note: If you need to adjust the factory preset, use the Up / Down arrows as necessary. If not, repeat this step. The gauge will return to PSIG. Press the “M” button to enter back into Calibration mode.

8. This completes calibration and the system should display “PSIG”.

9. Slowly release/bleed the pressure off and observe the gauge is responding to your pressure drop.

10. Once you reach zero – you may still have static pressure, please do not continue to reset zero as this will affect calibration span over time.

Note: If you feel comfortable that the gauge is properly calibrated and within acceptable tolerances, please turn off the gauge to lock in you calibration settings until the next calibration is required.

SECTION 1 System General Information: 1.1 General Information: The HDI 3300 series is built to withstand the rigors of the oilfield. It is designed to provide the user with both laboratory accuracy and field repeatability. The HDI 3300 Temperature Gauge System provides you with the capability for the remote monitoring of temperatures. This manual describes the installation, operation, maintenance and calibration of the HDI 3300 Temperature Gauge System. This manual shall provide the user with information necessary to properly and fully utilize the instrument. Included in this manual are all the necessary procedures to install and maintain this instrument properly. 1.2 Unpacking and Inspection: Upon receipt of the equipment, assure that all items are accounted for on the packing list. If any items are missing, immediately inform the freight forwarder. Inspect all items for damage. If any items are damaged, immediately inform the freight forwarder and Houston Digital Instruments, Inc. 1.3 Precautionary Information: Assure all directions on the packages are followed during unpacking and handling. Extra care should be taken to assure that the temperature sensor, which is mounted in the transducer housing and flange supplied with the system, is protected from contact with any hard or sharp objects, i.e. screwdriver, fingernail, etc., during the installation of the sensor. Any evidence of mishandling or abuse shall void the warranty. 1.4 Personnel Qualifications: This equipment requires experienced personnel to handle, install and maintain. HDI may provide technical schooling if it is required.

SECTION 2 System Description: 2.1 Systems Description: The HDI model # 3300 is a battery powered, stand alone, electronic temperature sensing and display system. The display is a liquid crystal display (LCD), which includes both a numeric (5 digits) representation (for accuracy) and a bargraph (101 segments) representation (for trend), battery low indicators, optional slaved units, optional recorders and alarms may be included. The sensor itself is housed in a stainless steel case. The sensor is commonly housed in either a 1502 hammer union or a flange. Any style of housing may be specified by the customer. Once calibrated, the gauge and the sensor become a matched pair and the substitution of any component, including wire, requires recalibration of the system. The HDI Model # 2400 system will directly replace any panel gauge (6" diameter) with either a four bolt (90°) or a three bolt (120°) pattern without any modifications.


2.2 System Components: 2.2.1. Temperature Gauge: HDI Model # 3300 Temperature Gauges are available with any of the following ranges:

FARENHEIT -50 to +300 CELSIUS -50 to +150

BOTH BOTH 2.3 System Options: Custom designed systems will include, per the customers' request or customers' specifications, certain options required to meet offshore area classifications or specific customer requirements. The following are common examples that may be encountered. HDI offers the following available options at additional cost. 2.3.1. Remote Display: Remote displays may be provided to allow temperature indication at an alternate location. 2.3. 4/20 mA Output: HDI offers as an option, a signal current loop providing a 4/20 mA remote output that may be used for chart recorder inputs, slave gauges and/or data logging. This is a factory installed option and calibration is unnecessary. 2.3.3. 0-1 Vdc Output: HDI offers as an option, a signal loop providing a 0-1 Vdc remote output that may be used for chart recorder inputs and/or data logging. This option is externally powered. This is a factory installed option and does not require any field calibration. 2.3.4 External Power The external power (EPPM) option is available at 7-32Vdc. SECTION 3 Installation: 3.1 Components: 3.1.1. Temperature Gauge and Transducer: The temperature gauge and transducer are to be mounted by the customer at the locations deemed most suitable for such equipment. 3.1.2. Cables: Standard cable length is 50'. The maximum recommended cable length is 200'. Cable lengths can safely exceed this recommendation. Cable lengths from the sensors to the gauge, other than standard, shall have been specified by the customer to the factory in advance. Other cable types are available upon request. Cable shall be installed using acceptable standards for such installations. 3.2 Mounting Components: 3.2.1. Temperature Gauge: The temperature system gauge is designed to be installed in the standard 6" diameter cut-out hole in the panel. Both the 90 degree (4 screw pattern) and 120 degree(3 screw pattern) bolt patterns are designed into the gauge and all applicable hardware is included. Remove the #10 elastic stopnuts from the 10 X 32 screws, drop the gauge into the appropriate hole and replace the stopnuts. 3.2.2. Temperature Sensor: The temperature system transducer system comes from the factory as a complete assembly and only requires mounting of the housing using standard practices for such installations. Note: Special care should be taken to insure that the sensor mounted in the center of the housing, is


not allowed to make contact with any hard and/or sharp object as the sensor pill is vulnerable to this type of contact and the accuracy and the sensitivity could be affected. A wide variety of housings are available. Any evidence of mishandling or abuse shall VOID the warranty. 3.2.3. Temperature Gauge Wiring: Note: The temperature gauge, cable and sensor are a matched, calibrated system. In multiple systems, when connecting the gauge to the transducer, special attention must be given to insure that the appropriate pairs are being connected. A four digit number with a one letter prefix (i.e., A5121) or a five digit number (91512) is stamped in the top of the sensor housing and the same number appears on the ID. tag on the back of the temperature gauge as part of the serial number. If unsure, check to see that these numbers match. SECTION 4 Theory of Operation: 4.1 Temperature System: The major components of this system are the control head, the sensory system and the communications link (cable). The control head contains the power source for the system, the signal conditioning, processing, calibration, outputs and the display. The process of sensing temperature is begun in the control head by conditioning the power as a current constant source and then transmitting that as excitation to the sensor. This sensor when excited by the current source, will produce an electrical signal that is proportional to the temperature applied to it. This signal is then returned to the control head, via the comm. link for processing. Circuitry then converts the electrical signal to logic drive for the LCD. The only remaining components in the system are the scaling circuits which are part of the signal conditioning/processing and the temperature compensation PCB located inside the transducer housing. The "intrinsically safe" EXIA power source is a 3.6 volt, potted, replaceable, battery pack. The temperature gauge system requires only minimal power, therefore it is preferable to leave the pressure gauge in the "ON" position at all times.


SECTION 5 Operation 5.1 Front Panel FRONT PANEL SWITCHES

1. There are four pushbuttons located on the face of the HDI 3300. 2. These PIEZO (Pressure) switches give the operator the ability to adjust and alter the

settings on the HDI 3300. 3. A firm even pressure directly centered on the switch is required to activate it.


5.2 Power-On Self Test

POWER-ON SELF TEST (POST) 1. Located on the bottom-rear of the gauge is a Power-On toggle switch. 2. During the POWER-ON sequence the display goes through a series of internal tests

lasting 1-2 seconds. For approximately 5 seconds all of the displays on the panel are lit. After this period it defaults into the normal Operating Mode.

3. The operator can bypass this POST by pressing the ENTER (E) key on the front panel. 4. This visual POST is repeated whenever the operator turns the unit off, and then on again

after allowing for a three second wait to clear the system. 5. Pressing the DOWN ARROW at this time will display the individual Model Number.


5.3 Bar Graph Range Selection

System Scaling Units Selection 1. The HDI 3300 can cycle between the two available scaling units (if both are installed).

The gauge is available with custom options containing any individual or combination of these two Scaling Units.

FAHRENHEIT CELSIUS

2. If a Scaling Unit is not available it will simply be skipped in the sequence. Once your HDI 3300 has reached the end of the list, it will return to the top of the scaling list and sequence forward again.(If you have only one range, nothing happens)

3. During POST it will automatically default to the Centigrade mode if that option is installed. Otherwise it will default to the first available installed scale.

4. The operator can select a particular Scaling Unit by pressing the MODE (M) button on the front panel.

MODE (M) indicator turns OFF as the unit leaves the current

operating mode UP-ARROW *FAHRENHEIT changes to the CELSIUS range ENTER (E) Enters the available and displayed mode.

indicator turns ON and the current mode is displayed

If the operator passes the desired scale, the system must be cycled forward through the sequence until the particular unit is again displayed.


5.4 Setting the Alarm Set-Points or Triggers

The Alarm Triggers or Set-Points 1. The optional alarm TRIGGERS or SET-POINTS can be set in either range. Each HDI

3300 has two available TRIGGERS. There is one each for both the HIGH and LOW temperature warnings.

2. The ALARM TRIGGER locations are displayed on the HDI 3300 as FLASHING segments of the BAR-GRAPH. ALARM ARROWS are also shown beneath the BAR-GRAPH as a reminder of

whether that particular setting is for the HIGH or LOW TRIGGER. Shown in the center of the HDI 3300 is the HORN symbol indicating when an

ALARM condition is present. Either the current temperature is outside of the range scale, or one of the TRIGGERS has been exceeded.

The arrows in the upper right hand corner of the HDI 3300 will indicate whether the gauge detects a trend in the temperature fluctuations. This can be either a rising or falling condition


MODE (M) RUN Indicator turns OFF MODE (M) BG RANGE indicator turns OFF UP-ARROW ALARM SET indicator turns on. Low

ALARM arrow on. Low ALARM TRIGGER INDICATOR starts to rise

UP-ARROW Low ALARM indicator TRIGGER INDICATOR stops

ENTER (E) Low ALARM Trigger is set. Low ALARM ARROW OFF High ALARM ARROW ON

DOWN-ARROW High ALARM ARROW starts to drop DOWN-ARROW High ALARM ARROW STOPS ENTER (E) High ALARM TRIGGER IS SET

ALARM SET indicator Turns ON Low ALARM arrow OFF High ALARM arrow off

To CANCEL the ALARM TRIGGERS, toggle through the scaling units

Alarm indicators are blinking

NOTES

1. If the ALARM SET indicator is already ON and you want to change the current settings refer to the following:

2. In STEP 3, select the ALARM SET to deselect the current settings. Continue with STEP 4.

3. If you over or under-shoot the desired setting, use the opposite ARROW to move the TRIGGER point in that direction.

4. The operator cannot set the alarm triggers outside of the currently selected range.


5.5 Available HDI 3300 System Options

The HDI 3300 Temperature gauge can be ordered with either the Fahrenheit,

Centigrade or both sets of scales.

The HDI 3300 is available in models either with or without alarm outputs.
