IntroductionThis manual contains calibration and installationinformation for Moore Industries’ Watt/Watt-hourTransducer (PWH). A description of the PWH anduser maintenance information are also contained inthis manual. Associated tables and illustrations areprovided for reference purposes.

The PWH is designed to accurately measure the trueroot-mean-square (rms) power consumed byelectrical equipment or systems. It electronicallycomputes this consumption and produces an analogand a pulse output, which are proportional to theinput. The output of the PWH can be directly input tocounters and controllers.

The PWH is a highly accurate multiplying device thatoffers excellent long term stability. It requires minorperiodic maintenance and operates virtuallyunattended.

This manual contains notes that must be observed toavoid minor inconveniences during calibration orinstallation of the PWH. The following definitiondescribes these captions:

A NOTE shall contain technical or literary informationof a helpful nature. This information is intended toaid the reader's understanding of the subject beingdiscussed and/or minimize inconveniences whileperforming technical tasks.

DescriptionThe PWH is an AC energy transducer that producesa watt (analog) and a watt-hour (pulse) output fromvoltage and current inputs. This watt/watt-hourtransducer is factory-configured as a 1-, 1.5-, 2-,2.5-, or 3-element (inputs) device.

A 1-element device accepts one voltage input andone current input. A 1.5-element device accepts onevoltage input and two current inputs. A 2-elementdevice accepts two voltage inputs and two currentinputs. A 2.5-element device accepts two voltageinputs and three current inputs. A 3-element deviceaccepts three voltage inputs and three current inputs.The combination of voltage and current inputs aresummed together to produce the analog and pulseoutputs.

The PWH is factory-configured to predeterminedspecifications from a variety of available input andoutput ranges (see table 1). Its outputs areconfigured to meet a number of applications whereremote indication and/or automatic control functionsare required.

The PWH is powered by one of two means: anexternal 120/240Vac source or an internallygenerated voltage obtained from the voltage input.

The PWH is packaged in an extruded aluminumenclosure, and is availble in either a surface-mount(SM) or DIN-rail-mount (DM) housing. Depending onthe type output required (relay or solid-state), SMand DM housings are either horizontally or verticallymounted on a vertical plane.

Each PWH is individually configured to meet theapplication needs of the user. This manual does notcover all possible configurations individually.However, the following is a list of options availablewith the PWH:

• 50 Hz input frequency (option 50H)

• 400 Hz input frequency (option 400H)

• 85-150 Vac external power (option 120AC)

• 170-300 Vac external power (option 240AC)

• 25-125% calibration range (option CAL)

• Case ground terminal (option CG, SM units only)

CalibrationEvery PWH is factory-calibrated to userspecifications prior to shipment. This calibrationensures that every unit meets the user's performancerequirements before it leaves the factory.

Moore Industries uses sophisticated equipment tocalibrate the PWH. However, should the need ariseto check out or calibrate the PWH in the field, theuser should read this section carefully before makingany adjustments to the unit. If questions arise, theuser is advised to contact Moore Industries'Customer Service Department for assistance.

In determining the need for calibration, the unit'sanalog and pulse outputs must be checked closely.The desired outputs must be attainable from correctjumper settings and potentiometer adjustments.Also, the unit must be supplied inputs which haveknown values.

Jumpers. Solderless jumpers are used for coarsesetting of the pulse output rate. To verify or changejumper settings in the field, partial disassembly of theunit is required. Six slotted screws along the outeredge of the front panel secure it to the housing. Toaccess the jumpers, these six outer screws must beremoved and the front panel pulled away from thehousing (see figure 1).

Attached to the inside of the front panel are threeprinted circuit (PC) boards. The first set of jumpersare located on the component side of PC3 or PC4,and the second set are on the left side of PC1.

Units configured with mercury-wetted relays (optionsRMB or RMU) are vertical-mount units. These unitsuse PC3. Figure 2 shows the jumper locations anddesignations for PC3. Table 4 contains the output-rate jumper settings for PC3. The first column oftable 4 lists the coarse pulse output rate achieved bysetting the corresponding jumpers.

Units configured with solid-state outputs (optionsPRB or PRU) are horizontal-mount units. These unitsuse PC4. Figure 3 shows the jumper locations anddesignations for PC4. Table 5 contains the outputrate jumper settings for PC4. The first column oftable 5 lists the coarse pulse output rate achieved bysetting the corresponding jumpers.

NOTEPC3 and PC4 are the smallest circuit

boards of the three boards contained in aunit. Either PC3 or PC4 are used in the

PWH, but not both.

Jumpers on PC3 and PC4 are set based on thedesired output. After determining a suitable pulseoutput rate, locate the next highest number in thefirst column of table 4 or 5. Jumper positions listedacross that row are the required settings to generatethe coarse pulse output listed. All jumpers must beused except on unidirectional units.

Figure 4 shows the location of the second set ofcoarse output-rate jumpers. The jumpers on PC1bring the output rate, set by the jumpers on PC3 orPC4, to within 5-percent of the desired pulse rate.

To determine which jumpers to set, the desiredoutput rate is divided by the output rate listed in table4 or 5. The percentage derived from this is matchedwith the nearest number (listed in percent) in the firstcolumn of table 6. Jumpers listed across that roware the required settings to bring the pulse rate towithin 5-percent of the desired output rate.

Refer to the calibration procedures in this manual forstep-by-step instructions in setting these jumpers.

Adjustments. There are three potentiometeradjustments used during calibration. These threeadjustments are accessible on the front panel andare labeled “WATT CAL”, “WATT ZERO” and “WATT-H CAL”.

The WATT CAL and WATT ZERO potentiometersaffect the analog output, while the WATT-H CALpotentiometer fine adjusts the pulse output.

Inputs. For calibration, full-scale inputs are required.Each unit has been individually set at the factory forpredetermined inputs and outputs. A label attachedto the unit identifies what the full-scale inputs are forthat unit. These full-scale inputs must be supplied tothe PWH for proper calibration.

Calibration Setup

Table 7 lists the equipment required to check out orcalibrate the PWH. This equipment is not suppliedwith the unit and must be furnished by the user. Theuser should ensure that equipment used for theseprocedures meets the minimum specifications listedin table 7 .

JAJBJCJDJE

PWHPage 11

Figures 5 through 9 are the calibration setupdiagrams for the 1-, 1.5- 2-, 2.5-, and 3-elementPWH’s. Refer to the applicable illustration for thetype unit being calibrated.

Calibration Procedures

The following calibration procedures pertain to all fivePWH configurations. These procedures are writtenfor a PWH configured for 120 Vac, 5 A input (500 Wper element) and 0-1 mA output. In the case of 1.5-element units, the input power must be 250 Winstead of 500 W. For 2.5-element units, the inputpower must be 374 W. Make appropriateadjustments to input and output values if the unitbeing calibrated is configured differently thandescribed here.

Although the analog output and the pulse outputprocedures are separate, the same illustration isused for both.

NOTEIt is assumed that a full-scale input

source of the proper characteristics isavailable and connected as shown in the

corresponding illustration.

Analog Output:

1. Set AC test switch to open (off).

2. Monitor AC voltmeter and adjust input voltage for120 Vac reading.

3. Check DC current meter; if a reading other thanzero is detected, adjust WATT ZEROpotentiometer on PWH for a zero reading(minimum output).

4. Set AC test switch to closed (on).

5. Monitor wattmeter and adjust input current untilmeter reads 500 W (full-scale input).

6. Monitor DC current meter and adjust WATT CALpotentiometer on PWH for 1.000mA reading(maximum specifed output).

7. Check linearity by adjusting current up anddown within specified range, and comparereadings on wattmeter and DC current meter.Readings should be proportional.

PWHPage 12

Figure 5. Calibration Setup, 1-Element PWH

Pulse Output:

1. Calculate number of counts-per-hour (pulse rate)output for full-scale input as follows:

a. Determine what the pulse output represents(e.g., 1 pulse per watthour (Wh), 1 pulse per2 Wh, etc.)

b. Identify the number of elements on unit andamount of full-scale power to be input perelement (e.g., 3-element, 500 W)

NOTEUse "2" for 1.5-element units and "3" for

2.5-element units in step 1.b.

c. Multiply full-scale input power by number ofelements on unit (e.g., 500 X 3 = 1500 W)

d. Divide total full-scale input by amount ofdesired time between each pulse(e.g., 1500 W/1 Wh = 1500 counts per hour(CPH), 1500 W/2 Wh = 750 CPH, etc.)

Mounting

Depending on the housing style and options ordered,the PWH is either surface mounted (SM) or DIN-railmounted (DM). Figure 10 contains the mountingdimensions for both these housing styles. Whenmounting the PWH, ensure it is mounted on avertical plane in an area free of dust, moisture andcorrosive elements.

PWHs ordered with the RMB or RMU output optionmust be mounted on a vertical plane with their lengthextended vertically. This positioning is necessary forproper operation of the mercury-wetted relay insidethe PWH. The correct upright position is identified bythe layout of the unit’s front panel.

The mounting dimensions for vertical-mount units arethe same as those given in figure 10. Figure 11illustrates a 3-element, vertical-mount front panel forreference purposes. Vertical-mount units arepackaged in either an SM or DM housing.

Surface-mount (SM) units may be mounted on anyvertical plane. However, it is recommended that thePWH be mounted on a surface that helps dissipateheat, especially if the ambient temperature isunusually high. Surface-mount units have fourkeyhole cutouts in their mounting plate for easymounting and removal (see figure 10).

The DM housing is designed for mounting onstandard DIN rails. The rear of the unit is equippedwith two mounting clips (see figure 10), which attachthe unit to the rails; either 32 mm (1.26 in) or 35 mm(1.38 in) rails.

Electrical Connections

Every PWH is equipped with the same number ofterminals. The number of elements a PWH isconfigured for determines which terminals are usedfor installation. Terminal designations are clearlymarked on the front label of each unit. Figures 12through 16 are installation hookup diagrams for thefive PWH configurations.

Terminal connections are made in the same relativepositions for horizontal- and vertical-mount units. Avertical-mount unit is basically a horizontal unit thathas been rotated 90 degrees to its left. Figure 11illustrates the front panel of a 3-element, vertical-mount PWH. Vertically mounted units have relayoutputs. The FWD PULSE OUT terminals 6B, 6Cand 6D are all used for the relay output. Horizontallymounted units only use terminals 6B and 6C for thesolid-state output.

OperationSince there are no LED’s or digital displays tomonitor on the PWH, it operates unattended.However, the PWH may become warm duringnormal operation, especially if the ambienttemperature is unusually high. This operatingcondition is normal for power transducers and shouldnot cause alarm, unless a malfunction is alsodetected.

MaintenanceThe PWH is built with highly reliable components,which allows this device to operate unattended forextended periods of time. Because of this highreliability, field maintenance is limited to ensuring thatwire terminals on the unit are clean and tight. It isrecommeded that the PWH be inspected formounting security, terminal corrosion and generalcleanliness at least once every six months.Figure 11. Vertical-Mount PWH Front Panel
