DryCool ERV - Unit Control Sequence Unit Control Overview The DryCool-ERV is designed to provide an economical way to control the space dew point while delivering room neutral supply air. If the system is operating in the occupied mode and the outside air is warmer than 75F (adjustable) or the dew point is greater than 54F (adjustable) or in the heating mode (anytime the outside air is below 50F, adjustable) the enthalpy wheel will operate. In the dehumidification mode, the incoming air is first pre-cooled and dehumidified using a single stage of direct expansion refrigeration. This cooler and dryer air is then passed through a regenerative desiccant wheel to further reduce the moisture content and reheat the air to a neutral level. The desiccant wheel’s ability to absorb moisture is regenerated with a separate air stream that is heated with the waste heat from the refrigeration reactivation condenser of the same direct expansion system. If the return air dew point remains high, 2nd stage of direct expansion refrigeration will be turned on to assist in removing moisture from the air stream. Should the DX coil leaving air temperature drop below 45F the number of refrigeration circuits in assist will be reduced. When the supply air temperature is above 75F dry bulb, 2nd stage of cooling will be turned on if it was idle. Heating the supply air is accomplished with a modulating gas fired burner or electric heat to maintain the supply air temperature set point.

Unit Start-Up

1. The disconnect switch must be turned “On” and can remain “On” for the life of the unit, except for periodic maintenance and service.

2. Place the DDC enable HAND-OFF-AUTO (HOA) switch to the “AUTO” position. The DDC outputs will operate when the switch is in the “AUTO” position, subject to the remote DDC enable contact (by others) being closed and the Unit Enable binary value set to “Enabled” by the Building Management System or manually through the LCD Display. The “HAND” position of the HOA switch allows manual override of the remote DDC enable contact.

3. One of the two operating modes, occupied or unoccupied, must be selected by the Building Management System or manually through the LCD Display. The dehumidification mode must be active for the unit to dehumidify the supply air.

4. To shut down the unit, it is only necessary to place the DDC enable HOA switch to the “OFF” position or set the Unit Enable binary value to “Disabled”.

Unit Operation Once an operating mode is selected by the building automation system or the unit keypad/display, the Supply Fan will start. After air flow is proven, the unit will operate in the mode selected. Dehumidification: The dehumidification mode can be activated in three ways. First, the BMS can call for DH based on space humidity level. Second, the unit can activate the DH mode if the dew point downstream from the enthalpy wheel is >54F (adjustable). Third, the Optional space sensor can call for DH based on space humidity level. A return air dew point >52F (adjustable) will control the staging of the compressor circuits for assisting in dehumidification. When the supply air temperature is above 75F dry bulb, 2nd stage of cooling will be turned on if it was idle. Cooling: Cooling can be activated by the BMS, the optional space sensor, or when the dew point downstream from the enthalpy wheel is <55F and the dry bulb temperature is >75F. The compressor will stage on to provide cooling based on a supply air temperature no greater than 75F. A call for DH will override the cooling mode. There is only one stage of cooling. Heating: Heating can be activated by the BMS, the optional space sensor, or when the dry bulb temp past the enthalpy wheel is <65 F (adjustable). The gas or electric heater will be activated to maintain a supply air temperature of 75F by modulating the heat output. The first stage of heat shall be a maximum of 25% of full capacity. Occupied Mode: Outdoor air damper will open, and the recirculation air damper will close. If the outdoor air temperature or dew point is high enough or if the heating mode is active, the enthalpy wheel will operate and exhaust fan will start. The unit will operate to maintain occupied space conditions. Unoccupied Mode: Outdoor air damper will remain closed, the recirculation air damper will remain open and the exhaust fan will remain off unless unit is in dehumidification mode. The enthalpy wheel will not rotate. The unit will operate to maintain unoccupied space conditions.

Operational Detail Dehumidification: Outdoor Air Temperature is not less than the Outdoor Air Temperature to allow dehumidification.

1. Compressor will turn on to pre-cool and pre-dehumidify the air stream. 2. The Desiccant Wheel will start to rotate. As the pre-cooled air passes thru

the Desiccant Wheel, additional moisture will be removed and the air temperature will increase.

General Installation Instructions

Location of the unit

The unit must be set on a flat, level surface and supported around the entire perimeter of

the base on either a roof curb or a slab. Proper service clearances must be provided on all

four sides of the unit as indicated on the unit General Arrangement (GA) drawing.

Noise Considerations

Noise control issues should be taken into consideration when installing a rooftop or

indoor air-handling unit. Modern roof and construction is normally lightweight. Where

the air handler is located over noise sensitive areas, noise may be a concern. Generally,

the distance between the roof-mounted equipment and the closest occupied spaces below

the roof is insufficient to apply standard sound control treatments. Units should be placed

above or next to spaces that are not acoustically sensitive and as far as possible from the

nearest occupied space.

On curb mounted units, it is recommended that holes be cut through the roof just large

enough to accommodate the ducts. The gap around the ducts should be properly sealed

with an acoustical sealant after installation of the ducts. Proper duct design will reduce

breakout and transition noise. Supply and return ducts should be lined with 1” minimum

acoustical duct liner.

Where roof construction is particularly susceptible to vibration transmission, an isolation

curb should be used. The curb deflection should be sized to be at least 15 times the

deflection of the roof due to the unit weight. (Ex: if the roof deflects 1/8” due to the unit

weight, the roof curb should deflect 1/8” x 15 = 1 7/8” due to the weight of the unit).

See ASHRAE 2007 HVAC Applications Handbook “Rooftop Mounted Air Handlers”

(47.6) for further information.

Indoor Installation

Noise: Units should be placed above or next to spaces that are not acoustically sensitive

and as far as possible from the nearest occupied space. Noise sensitive indoor

installations should incorporate unit vibration isolation to prevent sound transmission to

internal building structure.

Rev03

10-02-2009

Roof Curb (Optional)

The roof curb must be assembled according to the Roof Curb Assembly drawing. The

curb must be installed so that it is supported around the entire perimeter.

Drop in duct adapters should be fabricated and installed if the unit is ducted through the

curb.

3/8” thick by 1-1/2” wide closed cell gasketing must be installed around the perimeter of

the curb and duct openings prior to installation of the unit.

Counter flashing is recommended around the perimeter of the curb to prevent wind blown

water from being forced up the curb and seeping into the building between the unit and

the curb.

Lifting Unit

Unit must be lifted by crane using all lifting lugs located on the sides of the unit. The

crane must be selected to handle the weight shown on the General Arrangement drawing.

Spreader bars that are 2” to 4” wider than the unit width must be used to prevent the

rigging cables from squeezing the top of the unit. Failure to do so will damage the unit.

The base of the unit is 5” longer and 5” wider than the roof curb. There is a 2” wide rail

that must sit over the curb. When setting the unit on the roof curb, insure that the unit sets

properly over the curb.

Storage of unit

If the unit must be stored prior to final installation on the roof curb or slab, care must be

taken to set the unit on a flat surface. The unit is not designed to support its weight on an

uneven surface. Storage on an uneven surface may cause damage to the unit structure.

All unit openings shall be sealed for the duration of storage. Unit should be stored in an

area protected from weather, or completely covered with a waterproof tarp.

Rev03

10-02-2009

Utility Connections

Electrical:

Most units have a single point electrical hookup. Most units have a control panel with an

integral non-fused disconnect. An electrical service must be provided to accommodate the

unit MCA (Minimum Circuit Ampacity). It must be suitably protected against short

circuit and ground fault by a suitable means using the MOP (Maximum Overcurrent

Protection) stated on the nameplate.

Electrical service enters the unit from underneath through a prefabricated hole in the floor

panel. If the service is to enter the unit from the side of the unit as on a slab mount,

reference the unit GA drawing for location for electrical access. Attach a suitable

watertight connector where the electrical service enters the unit.

Control Sensors

Temperature and humidity controls or control sensors are generally mounted in the

conditioned space to control cooling, heating and dehumidification functions. The

conditioned space sensors should be carefully located so that they are away from supply

air outlets to prevent short cycling and inadequate control of conditions in the space.

Never locate control sensors in the supply air duct. This will result in short cycling and

compressor failure.

Discharge sensors for monitoring

Discharge sensors for monitoring and/or control of modulating heat should be located in

the supply ductwork downstream of the unit discharge. In no case shall the sensors be

located within the unit or immediately adjacent to the unit discharge. Preferably, the

sensor should be located after at least one directional change in the ductwork, or for

straight duct runs, at least twenty feet away from the unit discharge. Locating the sensor

closer than this may result in inaccurate readings due to inadequate air mixing or radiant

heat pickup from heaters.

Natural Gas or LPG:

CAUTION! Insure that the type of gas is correct for the heaters.

There are up to three gas connections on the unit on units so equipped. Gas service must

be provided to each connection. The gas service must be sized according to the

Equipment Data sheet located in the Manual or Submittal, or the unit nameplate located

on the electrical control panel. The piping and regulator must be capable of continuously

supplying the required BTUH at a pressure of 7 to 15 inches water column (11” to 15” for

LPG) with the burner(s) on at full fire. The piping installer must install a proper sediment

trap per National Fuel Gas Code NFPA 54 (ANSI Z 223.1) section 5.5, a pressure

regulator, and a union. The pressure regulator must be a lockup type to prevent excessive

pressure buildup during burner off periods.

Rev03

10-02-2009

Cooling Coil Drain Connections:

Cooling coils must be properly trapped. Lack of a proper trap will admit air into the

bottom of the condensate drain pan preventing draining of the pan. As water builds up,

the entering air will blow water out of the drain pan. The trap must be at least 8” deep

with a 4” high drain leg (see below). On units with positive pressure blow-through coils,

the trap dimensions must be reversed.

Evaporative Cooler Water and drain connections:

If the unit is equipped with an evaporative cooler, the ½” MNPT WATER connection

must be connected to a clean water supply. There is an air break built into the unit to

prevent back flow into the building water system in case of water pressure loss. The

installer must take proper precautions to prevent freezing of the water line in cold

weather. Heat tape and insulation or automatic draining of the line is recommended.

There is a 1” MNPT DRAIN connection that should be connected to the sewer.

CAUTION! The unit has a conductivity sensor that automatically drains the evaporative

cooler sump. DO NOT install a shutoff valve in the drain line. The 1” OVERFLOW

should be allowed to drain in a conspicuous location to allow detection. CAUTION! DO

NOT install a shutoff valve in the overflow line.

Vent connections:

Units equipped with a gas reactivation heater for will have a PVC pipe outlet labeled

“REACTIVATION VENT”. A small amount of reactivation exhaust will be emitted from

this vent when the reactivation fan is running. On outdoor units, this vent should be left

open to atmosphere. On indoor units, this vent must be routed to a drain or to a point

outside the building. The pipe must be continuously sloped ¼” per foot toward the drain

or outlet. If this vent is piped to a drain, it must be sealed to the drain to prevent

reactivation exhaust from entering the building.

Steam Coils:

CAUTION! Steam coils are subject to outside air conditions and can quickly freeze and

rupture during sub 32F weather if proper steam valves, traps, and piping design are not

utilized. Coils controlled by a modulating steam valve are particularly susceptible to

freezing.

Each coil must have its own steam trap.

Steam traps must be installed a minimum of 18” below the bottom of the coil. The pipe

size leaving the coil should be used to connect the steam trap. A sediment leg must be

installed below the pipe tee connecting the trap. Traps must be a float and thermostatic

(F & T) type. The trap must be sized to accommodate the design condensate flow rate at

½ PSIG.

A vacuum breaker must be installed at the top of the coil outlet header to insure proper

coil condensate drainage in the event that the steam supply does not keep up with the

condensation rate and sub atmospheric pressure would otherwise result. This event can

easily occur during startup conditions and especially where a modulating steam valve is

used.

The steam supply line must have a trap to insure that only steam enters the coil.

Details on proper steam piping and valving can be found in Chapter 22 of ASHRAE 2009

Fundamentals Handbook and Chapter 10 of ASHRAE 2008 HVAC Systems and

Equipment Handbook.

Failure to follow proper guidelines can result in freezing and rupture of the steam coils.

Ducting

Outdoor units

Duct connections for supply and return air are made to the bottom or to the sides of the

unit depending upon the option ordered. Duct connections must always be made to the

flanges sticking out of the unit, never to the sheet metal on the unit housing. Flexible duct

connectors should be installed between the unit duct outlet and the duct. Fans are sized to

accommodate 1” total external static pressure (supply + return) from the duct system

unless otherwise specified.

On supply discharge ductwork, allow several duct diameters of a single duct run prior to

branching of the ductwork into multiple runs to ensure even airflow and

temperature/humidity distribution. Details on ducting standards can be found in

SMACNA publication "HVAC Systems – Duct Design" and Chapter 18 of 2008

ASHRAE HVAC Systems and Equipment Handbook.

Most units have cooling, heating and dehumidification functions controlled by sensors

located in the conditioned space. As the controlled condition reaches the “on” set point,

the required function will energize. Wide variations in discharge temperatures can occur.

During cooling mode, the discharge temperature may be between 55F and 65F. During

dehumidification or heating, temperature may range from 85F to over 100F. Makeup air

units may have even greater variations. Discharge registers in the conditioned space

should be carefully located to prevent cold or hot air from blowing directly on people and

causing uncomfortable conditions.

Indoor Units Reactivation ducting: Reactivation air must be ducted to the outside of the building

away from any air intakes into the building. The duct should be at least the same size as

the reactivation outlet and as short as possible. The weather flapper must be removed

prior to duct installation. The duct must be insulated on the outside and sloped toward the

outside a minimum of ¼” per foot. The duct connections must be sealed so that air does

not leak out. The air inside the reactivation duct is very wet and moisture will condense

and cause corrosion if the proper material is not selected. The recommended material for

the inside of the duct is aluminum or stainless steel. The reactivation vent pipe on the side

of the unit must be piped to a drain or outside the building.

Makeup air ducting: Makeup air inlet(s) must be ducted to the outside. Care should be

taken to locate the inlet where it will not entrain air from a contaminating source.

Rnet port 4-pin port for interface with a BACview6, RS sensors, or local laptop access.

Xnet Remote Expansion port 3-pin port for communication with an I/O Flex 8160 point expander through the Xnet network.

Table 1. I/O Flex 6126 pointsPoint Type Specifics

Digital Outputs 6 digital outputs, relay contacts rated at 5A maximum at 250VAC. Use pins on the connector to configure contacts as normally open (NO) or normally closed (NC).

Input 12 inputs, configurable for dry contact, thermistor/RTD, 0-20ma input, or 0-10VDC input. Inputs 1 and 2 may be used for pulse counting. Input resolution is 12 bit A/D.

Analog Output 6 analog outputs, (outputs 1 and 2 are either 0-10v or 0-20ma; 3 through 6 are 0-10v only). Output resolution is 8 bit.

NOTE The beta release of the I/O Flex 6126 module does not yet support LonWorks SLTA, LonWorks plug-in, or Ethernet but will support these protocols in the future. References in this document to these protocols, and any other features that are not yet supported, are shown in grey text.


Figure 1. I/O Flex 6126 dimensions and layout - DRAFT


JumpersThe I/O Flex 6126 has the following jumper settings:

NOTE To avoid damaging the jumpers, grip them on the sides parallel to the jumper leads. The jumper leads must remain parallel to the row of jumper pins. See Figure 2.

Universal Input Mode Select Jumpers Select 0-10V, RTD Therm Dry, or 0-20mA to indicate what type of signal each input should expect.

Aux Pwr Out Jumper Select +24V or +5V if you are using this as an additional power source when the current input mode is being used.

AO Mode Select Jumpers Select 20mA or 10V, depending on what type of signal this output will send.

Full Half Duplex Jumper Select Full (4-wire) or Half (2-wire) for Port 2a.

NOTE This jumper setting must match the correct protocol settings in WebCTRL, or the module will not be able to communicate on Port 2a.

EIA-485/EIA-232 jumper Select EIA-485 or EIA-232 for Port 2a.

Rotary Address SwitchesThe I/O Flex 6126’s pair of rotary switches determines the I/O Flex 6126’s MAC address when it is placed on a BACnet/ARC156 or BACnet MS/TP network. The rotary switches define the MAC address portion of the device’s BACnet address which is composed of the network address and the MAC address.

These rotary switches can be set to anything between 1 and 99. One switch corresponds to the tens digit and the other corresponds to the ones digit. For example, if the module’s address is one, set the tens switch to zero and the ones switch to one, as shown in Figure 3.

Comm Selector DIP SwitchesNOTE You do not need to set the DIP switches if the Comm port is set to communicate BACnet-over-ARC156.

NOTE Port 1 is BACnet-over-ARC156 only.

Port 2a and Port 2b DIP SwitchesThe I/O Flex 6126’s DIP switches determine the baud rate and protocol used on the network port when it is configured for BACnet MS/TP, Modbus RTU, N2, LonWorks, or Ethernet. Set the DIP switch to the right for On or to the left for Off.

NOTE DIP switches 3 and 4 are not currently used on this module.

MountingScrew the I/O Flex 6126 into an enclosed panel using the mounting holes provided on the cover plate. Be sure to leave about 2 inches (5 centimeters) on each side for wiring.

Power WiringCAUTION The I/O Flex 6126 is a Class 2 device (less than 30VAC, 100VA maximum). Take appropriate isolation measures when mounting the I/O Flex 6126 in a control panel where non-Class 2 devices (for example, 120VAC) or wiring are present.

You can power several devices from the same transformer if you maintain the same polarity.

The I/O Flex 6126 has an operating range of 21.6VAC to 26.4VAC. If voltage measured at the I/O Flex 6126’s power input terminals is outside this range, the I/O Flex 6126 may not work properly.

1. Turn the I/O Flex 6126’s power off. This prevents the I/O Flex 6126 from being powered up before the proper voltage is verified.

2. Make sure the 24VAC power source is off.

3. Connect the power wires to the I/O Flex 6126’s power connector, making sure the proper polarity is observed for Ground and Hot (24VAC) (see Figure 1 on page 4 for location).

4. Apply power to the transformer.

5. Make sure that 24VAC is present at the power connector terminals.

6. Set the I/O Flex 6126’s address. Refer to “Rotary Address Switches” on page 4 for details about setting the address.

7. Turn the I/O Flex 6126’s power back on.

When the I/O Flex 6126 turns on, the Power, Run and Error LEDs turn on and the Run and Error LEDs begin blinking. The Error LED goes off once memory has been downloaded to the I/O Flex 6126. (See “LEDs” on page 15 for more information about LED signals.)


Communicating with the I/O Flex 6126

Downloading memoryThe I/O Flex 6126 can store one module driver and up to 999 Graphic Function Blocks (GFBs), depending on the size of the control programs. The I/O Flex 6126 requires the drv_ioflex module driver. You must be logged in to WebCTRL with the appropriate privilege to download memory.

NOTE Currently, memory cannot be downloaded through the Access Port. It can only be downloaded from WebCTRL via Ethernet to a router (for example, an LGE or an LGRM-E) and from the router over ARC156 or BACnet MS/TP to the I/O Flex 6126.

1. In WebCTRL, click the CFG button at the bottom of the navigation pane.

2. Click Download in the CFG tree control.

3. Click the Memory, Parameters, or Schedules boxes, depending on what you want to download.

4. Expand the tree in the action pane, click the I/O Flex 6126 you want to download to, then click Add. Repeat for other I/O Flex 6126s you want to download to.

5. Click the Execute Download button.

If any downloads failed, they are listed in the Failures section under the tree in the action pane. To retry a failed download, click on the I/O Flex 6126 in the Failures list, click Add, and click the Execute Download button again. If you do not want to retry a failed download, click the Clear Failures button.

NOTE Since a failed download indicates a system problem, you should never clear a failure. Locate and resolve the problem, and then retry the download.

6. Click the Properties button to refresh the screen. This removes the items from the Download Items list.

BACview6The I/O Flex 6126 can be configured with a BACview6 keypad/display on the Rnet port. The BACview6 allows a local operator to access information directly from the I/O Flex 6126 after a custom keypad file has been written and downloaded to the module.

NOTE If the I/O Flex 6126 is powered by a 40VA or higher transformer, no external power supply is needed to power the BACview6 and its backlight. However, to avoid overheating under these circumstances:

• use the BACview6’s built-in inactivity time-out control to avoid having the backlight on for an extended time

• provide adequate air circulation around the I/O Flex 6126 to dissipate heat


RS Pro and RS StandardThe I/O Flex 6126 supports up to 5 RS sensors on its BACview/RS sensor port. Following are allowable sensor types and combinations:

• one RS Pro,

• up to 4 RS Standards, or

• one RS Pro and up to 4 RS Standards.

The RS Pro is a thermistor-based temperature sensor. See Figure 4 for a diagram on how to connect the RS Pro to the I/O Flex 6126.

BACnet Networking

ARC156An ARCNET coprocessor allows the I/O Flex 6126 to communicate on an ARC156 network through the module’s dedicated ARC156 port, Port 1. ARC156 is a unique implementation of the industry standard, ARCNET. It differs from ARCNET as shown in Table 4.

The I/O Flex 6126 uses the BACnet protocol to communicate with up to 99 other devices on an ARC156 network at 156 kbps. A special communications cable is recommended for maximum signal integrity. This cable can be ordered from:

Magnum Cable CorporationCleveland, OH 44110-0500(800) 421-0820

Refer to the ARC156 CMnet Wiring Technical Instructions for more information about termination, repeaters, wiring, and ARCNET token passing.

NOTE You can verify that the I/O Flex 6126 is communicating on the ARC156 network segment by checking the module’s transmit and receive LEDs on the Comm port. Both LEDs should be active to indicate token passing.

BACnet MS/TPThe I/O Flex 6126 can be configured to communicate on a BACnet MS/TP network as an MS/TP master or slave device through the Comm port.

Inputs and Outputs

InputsThe I/O Flex 6126 is equipped with universal inputs that can accept both analog and digital input signals. All 12 inputs support thermistors, dry contacts, and 0-10VDC sensors and have a 12-bit A/D resolution; inputs 1 and 2 can be used for pulse counting.

The I/O Flex 6126 uses voltage dividers and current sensing resistors to convert electric input signals to volts, which are then measured and converted to the appropriate units. Scaling can be accomplished in WebCTRL on the module driver Properties page.

Input Signal TypesTable 5 describes the input signal types available on the I/O Flex 6126.

Input Wiring RestrictionsWiring restrictions for the I/O Flex 6126’s inputs are as follows:

• Maximum length: 50 feet (15 meters)

Table 5. Input Signal TypesSignal Type Description

Thermistor Precon type 2 (10kohm at 77 deg F). Thermistor input voltages should range between 0.489V and 3.825V.

Dry Contact A 5VDC wetting voltage is used to detect contact position. This results in a 0.5mA maximum sense current when the contacts are closed. Any switch, which has more than 412 Ohms effective resistance (0.2V) when closed, must have an interposing mechanical relay when used with OEMCtrl modules.

0 to 5 VDC The output impedance of a 0 to 5VDC source must not exceed 10kohms. The input impedance of the module is approximately 1Mohm.

1kohm RTD Platinum, nickel, or balco.

TroubleshootingIf you are experiencing problems communicating with the I/O Flex 6126, note the following:

• Use a meter to verify the a input power voltage is within 10% of 24VAC and that the VA of the transformer is at least 40VA.

• Make sure the program is downloaded and running.

• If the equipment is not running, double-check sensor wiring.

LEDsThe I/O Flex 6126 has several LED indicators to show the status of certain functions.

Power Lights when power is being supplied to the module.

NOTE The I/O Flex 6126 is protected by internal solid state Polyswitches on the incoming power and network connections. These Polyswitches are not replaceable and will reset themselves if the condition that caused the fault returns to normal.

Digital Output Status Lights when the digital output is activated.

Analog Output Status Lights when the analog output is activated.

Rx Lights when the module receives data from the network segment; there is an Rx LED for Ports 1 and 2a.

Tx Lights when the module transmits data over the network segment; there is a Tx LED for Ports 1 and 2a.

Run Lights based on module health. See Table 6 for explanation.

Error Lights based on module health. See Table 6 for explanation.

Formatting the ModuleCAUTION Before formatting the module, please note that ALL memory will be erased. You must be able to download memory to the module after formatting a module.

Rarely is it necessary to format a module. We strongly advise NOT formatting a module without consultation with a factory representative or an experienced technician. Formatting causes the module to delete the GFB in memory permanently, and memory will have to be downloaded to the module.

If communications are lost with the module, formatting it can narrow down the problem. However, before formatting the module, follow these steps:

• Remove all external wiring other than power.

• Through the access port, attempt to get a Module Status.

• If you can communicate, the problem with communications involves one of the wires you just removed. Reconnect each wire one at a time and try to get a Module Status in between to figure out where the problem lies.

• If you cannot communicate and you have the system files for downloading memory to this module, try the format procedure below. Then try again to get a Module Status. If you cannot communicate with the module after a format, send it in for repair. If you can communicate after the format, formatting has resolved the problem. You will need to download memory to the module and reconnect all the inputs and outputs.

Formatting Procedure1. Turn the I/O Flex 6126’s power off. Make sure the module’s address switches are addressed

correctly and are not set to ‘0 0’.

2. Short the Format pins with a jumper covering both pins or with the blade of a screwdriver. Maintain the short while performing step 3.


The Error LED flashes three times in sync with the Run LED.

Hi-Flo®

Camfil Farr Product sheet

Hi-Flo® 1203 - 0808

Camfil Farr—clean air solutions

The Camfil Farr Hi-Flo® offers high efficiency ASHRAE grade filtration to address today's indoor air quality problems. The Hi-Flo can remove contaminants such as fumes, smoke, bacteria, fungi, and virus-bearing droplet nuclei. The Hi-Flo is also the filter of choice for the removal of nuisance contaminants such as pollens, paper dust, and other atmospheric impurities. Hi-Flos are available in efficiencies of MERV 9, MERV 11, MERV 13 and MERV 14 when evaluated per ASHRAE Standard 52.2-1999 and have a respective MERV-A value of 9, 11, 13 or 14 when tested using the conditioning step as specified in Appendix J of the same Standard. High Lofted Air Laid Media

The Camfil Farr Hi-Flo incorporates high lofted air laid micro fiber glass media to ensure reliable efficiency throughout the life of the filter. Its small fiber diameter and uniform lofting results in consistent sub-micron particle capture and a low resistance to airflow throughout the life of the filter. A synthetic micro mesh media backing ensures media protection and support in turbulent or varying airflows. The Hi-Flo's particle capture performance and filter configuration are unaffected by dust loading and/or humidity.

Controlled Media Spacing

Camfil Farr is the only manufacturer to offer controlled media spacing to minimize pocket-to-pocket contact, ensure uniform airflow and allow full utilization of the media area. The effect results in the lowest life cycle product cost for your facility. Your selection of the length and number of pockets should be based upon the required airflow through the system.

Extended surface filter with controlled media spacing

(CMS) for longer life and the lowest life cycle cost of any

pocket filter

Extended Surface Multi-Pocket Air Filters

The above chart shows relative efficiency values at various particle sizes when tested in accordance with ASHRAE Standard 52.2-2007. When tested in accordance with Appendix J of that Standard the Hi-Flo maintains these efficiency values throughout the life of the filter.

A 5-star rating indicates that this filter performs in the top 20% of all products of similar construction in the HVAC industry. Factors of consideration include maintained effi-ciency, energy usage and resistance to air flow. Detailed evaluation information is available from your Camfil Farr sales outlet or on the web at www.camfilfarr.com.

Controlled Media Spacing (continued) Typical bag filters allow pocket-to-pocket contact, causing loss of effective media area, non-uniform airflow and an excessive pressure drop over the life of the filter. Camfil Farr’s variable length pocket stitching, through the use of continuous thread filaments, helps keep as many as 12 individual pockets in a perfectly aligned V-shaped configuration. This tapered pocket effect equalizes the media entrance and exiting areas. Air travels evenly through the filter at an even media velocity for uniform dust loading and a maintained low pressure drop. The benefits include: • Increased filter life • Reduced maintenance costs

• Minimized fan horsepower requirements • Reduced energy expenditures. Stitch Sealant & Adhesive Bonding

Camfil Farr completely seals pocket stitching to eliminate the possibility of air leakage through the stitching penetrations. This unique sealant maintains a flexibility that is unaffected by varying airflows. The media is also bonded around the pocket retainers to ensure a strong pocket-to-retainer seal and minimizes potential for pocket failure. Sure-Clench Crimp

Each galvanized steel pocket retainer is fastened with Camfil Farr’s exclusive Sure‑Clench Crimp, creating a positive lock between pockets and eliminating the possibility of air bypass. The pocket retainers include rolled edges to prevent damage to the media area and minimize sharp edges that may create a hazard to filter installers. Four retainer clips assist in securing pocket retainers to the header frame. Galvanized Steel Header A box-channel header, of one-piece corrosion resistant galvanized steel, includes rolled edges to prevent damage to the filter media. When combined with the Sure-Clench Crimp and galvanized pocket retainers, a rigid and durable assembly is created. Camfil Farr manufactures the Hi-Flo to be capable of withstanding up to 5.0” w.g. in normal HVAC application.

Leak-Free Filter Performance Every Camfil Farr Hi-Flo includes a gasket on the vertical edge of the filter header. In a side-access housing, filters are mated header-to-header. The gasket prevents air bypass and ensures that the air filter will clean all of the air moving through the system. Performance

Hi-Flo filters are manufactured from microfine glass fibers for consistent and long-term high efficiency performance. They are available in fractional efficiencies from 40% to 95% on particles as small as 0.3 micron in size. MERV values range from 9 to 14 when evaluated under ASHRAE Standard 52.2-2007. The respective MERV-A values for each efficiency are the same as their reporting value indicating the Hi-Flo will maintain particle capture efficiency throughout the life of the filter. Configurations for any Application

Camfil Farr Hi-Flos are available in a variety of configurations to suit your air movement requirements. Common configurations include from 3 to 12 pockets, depths of 15" to 36", and up to 129 square feet of effective media area. When selecting a Hi-Flo for your system, you should select a filter with the greatest effective media area within the airflow parameters and space limitations for your system. This will ensure a long filter life and a consistent low resistance to airflow over the life of the filter. Fewer filter changes will be required, thus reducing replacement, labor and disposal costs. An additional benefit includes reduced system horsepower requirements, thus lowering the facility’s energy expenditure. Lowest Life Cycle Cost All of these components combine for the lowest life cycle cost, the lowest average pressure drop (energy savings), and consistent high efficiency particulate filtration throughout the life of the filter.

The Cambridge Air Filter Company manufactured side-access housings that required a 1.12” header to fit in a nominal 1¼” filter track. To order Hi-Flos for these housings, add a ‘W’ to your model number or seek factory guidance. Synthetic Media Option Camfil Farr also offers an electrostatically enhanced synthetic media extended surface pocket filter. Available in efficiencies of MERV 9, MERV 11, MERV 13 and MERV 14, the Camfil Farr S-Flo offers an additional economical choice for less demanding applications. Consult Camfil Farr Bulletin 1205.

3P Glide/Pack® 2401 - 0606

Camfil Farr—clean air solutions

The Camfil Farr 3P Glide/Pack® has set the standard for side-access housing integrity for over 20 years. With its integral universal final filter holding frame virtually all of the air seen by the filter will be treated by the filter. Each Camfil Farr 3P Glide/Pack includes: • 16-gauge galvanized steel construction with pre-

drilled standing flanges to mate to existing HVAC equipment. All components are weatherproof for interior or exterior installation

• Dual-access doors for filter service from either side of the unit. The doors swing-open and are engineered to be square to the housing flange. UV resistant star-style handles assure a tight seal each time the access doors are opened and closed

• High-memory sponge neoprene door gaskets to ensure door-to-filter seal (less than one half of 1% housing to ambient leakage)

• A poly sponge door gasket to assure a proper door-to-filter seal

• A polypropylene fin seal on the main filter track to eliminate filter air bypass (less than 1/2 of 1% leakage across the final filter assembly at rated airflow)

• An integral pneumatic fitting for the installation of an optional static pressure gauge capable of evaluating any single stage or multiple stages of installed filters

• An aluminum filter track allowing for filtration combinations that include:

• A 2” nominal size prefilter track (with filter slide rails to facilitate easier prefilter service)

• A 6” or 12” deep box-style final filter with 1” nominal size header or full size box style filter in a frame assembly

• A pocket style final filter with header for frame or track installation

• A 12” deep box style carbon filter for gaseous contaminant removal

For those that are concerned about air quality and desire a housing that assures that the system contaminant removal efficiency is the same as the rated filter efficiency the Camfil Farr Glide/Pack continues to set the standard by which other HVAC components are judged.
