Output Connections:
Analog (4-20mA) Outputs
The PowerTrak provides two separate 4-20 mA analog signal outputs. Each output can individually be set by DIP
switches to represent a different parameter. Both 4-20 mA output loops require an external 24 VDC power supply
and polarity should be observed. See Figures 1 and 2 for wiring diagrams. The “LOOP 1 UP” and “LOOP 2 UP”
LED's will vary in intensity with the signal when a valid current loop is connected in series with these outputs. If
these LED's are "OFF" there is an open circuit in the current loop.
Digital Outputs
The PowerTrak provides a KWH pulse output and a low voltage alarm output. Both outputs are solid state relays
rated for 50 VAC/DC 100 mA maximum. See Figures 1 and 2 for wiring diagrams. When driving a DC relay coil, a
reverse connection protection diode (like 1N4004) is recommended across the relay coil. If driving an AC relay coil,
a varistor across the relay coil is recommended (like V39ZA1). The ”KWH PULSE“ LED is “ON” when the KWH
pulse contact is closed and “OFF” when the contact is open. The ”SYS VOLTS OK“ LED is “ON” when all phase
voltages are above the low voltage alarm settings. The LED is ”OFF“ when any phase voltage drops below the low
voltage alarm setting.
PowerTrak Communications
The PowerTrak can be supplied with an optional communications module allowing access to all of the monitored
parameters. Refer to the data sheet supplied with the communications module for information on wiring, protocols,
etc.
INSTALLATION - Continued
The PT-9000 may be ordered with an optional two line, 16 character, alpha-numeric LCD display for local monitor-
ing of power parameters. Each line of the display can be manually scrolled with the yellow, cover mounted buttons
to view up to 23 different displayed parameters. No calibration of the display is required. When using potential trans-
formers on systems greater than 600V, multiply KW, KWH, KVA and VOLT displayed values by the PT ratio to get
the correct parameter value. PT ratio=Primary/Secondary. Example: 4800V/120V=40

KWH and Peak Window KW Reset
The KWH display value can be reset to zero by pressing the CLEAR KWH COUNT button inside of the PowerTrak.
The peak window KW value can be reset to zero by pressing the CLEAR PEAK KW button inside of the PowerTrak
or by momentarily interrupting power to the current loop connected to MA OUT 2 terminals.
