DIP SWITCHES
Setting the DIP switches according to system requirements is suggested before applying power to the PowerTrak. However, it is
not necessary to remove power from the PowerTrak in order to make changes to the DIP switch settings.
A1 - A2: Define the power system type. Set these switches to match the type of system that is to be monitored. Select from
3-Phase wye or delta and single-phase 2-wire or 3-wire systems. See Table 1 for switch settings.
A3 - A8: Define the low voltage alarm threshold. Select an appropriate value for the system voltage that is monitored.
For delta systems, low voltage is measured line-to-line. For wye and single-phase systems, low voltage is measured
line-to-neutral. Select from alarm threshold values ranging from 51 to 540 volts. See Table 2 for switch settings
B1 - B2: Define the KWH per pulse value. Set these switches to obtain an optimum pulse rate that can be read by the BAS
controller or data acquisition equipment. Select from 10, 1, 0.1, and 0.01 KWH per pulse values. See Table 3 for
switch settings.
B3 - B5: Define mA loop #2 signal type. Set these switches for the power parameter to be represented by this
4-20 mA output. Select from seven different parameters, Total KW, Window KW, Peak Window KW, Total KVA,
Total Power Factor, True RMS Voltage*, True RMS Current*. See Table 4 for switch settings.
B6 - B8: Define mA loop #1 signal type. Set these switches for the power parameter to be represented by this
4-20 mA output. Select from seven different parameters, Total KW, Window KW, Peak Window KW, Total KVA,
Total Power Factor, True RMS Voltage*, True RMS Current*. See Table 4 for switch settings.
C1 - C5: Define the current transformer ratio. Set switches to match the primary current rating of the current transformers con-
nected to the PowerTrak. Select from CT primaries ranging from 50 to 6000. See Table 5 for switch settings.
* Voltage and current outputs are the average of the three-phase true RMS values.
SYSTEM VOLTAGE SELECT SWITCH
Set the SYSTEM VOLTAGE SELECT switch to the correct line-to-line system voltage (or potential transformer secondary volt-
age, if used) connected to the PowerTrak. If the actual system voltage is greater than the selector switch setting, the over volt-
age LED will flash and the PowerTrak will cycle on and off to protect itself from over voltage. If this occurs, turn the selector
switch to the correct system voltage setting.
AUTO-CONFIGURATION
After all wiring connections are completed, the DIP switches are set correctly, the voltage selector switch is set to the correct sys-
tem voltage, and the electrical system is energized, the PowerTrak can be auto-configured. To initiate the auto-configuring system,
press the AUTO-CONFIG button. The PowerTrak will examine the current and voltage waveforms for correct phasing and CT polar-
ity. During the auto-configuring process, the Volts/Amps phasing LED’s and CT reverse polarity LED’s will light in sequence. When
the process is completed only one of the Volts/Amps phasing LED’s will be lighted indicating the actual phasing between the voltage
and current inputs to the PowerTrak. A lighted CT polarity LED indicates that the corresponding CT is installed or wired backwards
giving a reverse polarity. A correctly wired PowerTrak will be indicated by all CT polarity LED’s extinguished and the left most
Volts/Amps phasing LED lighted. Should any of the other phasing or CT polarity LED’s be lighted, the PowerTrak will electronically
“fix” the wiring errors and provide correct and accurate outputs. No time consuming troubleshooting or wire swapping is required.
Note: The Auto-Configuration and Manual Configuration functions cannot be used with summing current tranformers. Proper wiring
of CT’s and voltages must be observed when using summing CT’s.
If the auto-configuring system is unable to determine the correct wiring configuration, the PowerTrak will enter the manual con-
figuration mode and the manual config yellow LED will light. If this occurs, try initiating the auto-configuring system again, by
pressing the Auto-config button. If the manual config yellow LED lights again then check the following:
1. Verify all switch settings on the PowerTrak are correct for the monitored electrical system.
2. Verify all phase voltages are present at the SYSTEM VOLTAGE terminal block using a voltmeter and/or the PowerTrak dis-
play option.
3. Verify all Current Transformer inputs are present at the CT INPUTS terminal block using a clamp on ammeter and/or the
PowerTrak display option. Current transfomer secondary wires (X1 & X2) should be connected to the PowerTrak in pairs.
NOTE: For the auto-configuring system to function properly, these four conditions should be met:
1. Load amperage must be above 5% of the CT primary rating.
2. The system power factor must be greater than 0.64 lagging.
3. The power factor should not be leading.
4. The power system waveform does not have severe harmonic distortion.
After checking these items and making any corrections, press the AUTO-CONFIG button again. If the PowerTrak is still unable
to determine the correct wiring configuration, Manual Configuration will be required.
MANUAL CONFIGURATION
The electrical system load should be relatively constant during the manual configuration procedure. To manually configure the
PowerTrak, set the DIP switches so that one of the 4-20 mA outputs represents Total KW. Connect a meter set to read DC milliamps to
this output, or if the PowerTrak has the LCD display option, set one of the display lines to read Total KW. Next, press the manual config
CT polarity button (CT POL) to scan through the different CT polarity combinations. Each time record the reading of theTotal KW display
or mA output. Allow the reading to stabilize before recording it. After reviewing all of the CT polarity combinations, press the manual con-
fig V-A MATCH button and repeat the process of scanning through the CT polarity combinations. After trying all possible combinations of
V-A match and CT polarity (there are 48 possible combinations, see the manual configuration worksheet) the correct configuration is the
one producing the highest value of KW on the display or the highest mA reading on the meter. Manually set the PowerTrak to the cor-
rect configuration using the CT POL & VA MATCH push buttons.
