ON = Enables PM Alarm Relay and DC Output supervision for DC Power Failure, Shorted, or Low
OFF = Power Monitor Off - Reduces No-Load Current Draw by 35 mA.
ON = Enables Battery Set supervision for Low or Shorted Battery, or Blown Battery Fuse
OFF = No Battery Supervision
ON = Enables AC Power Supervision for AC Power Failure or Blown AC Fuse
OFF = No AC Power Supervision
ON = Enables a 10-second Fault Alarm delay for masking short AC power failures or low battery alarms.
OFF = Fault Alarms are instantly activated.

Supervision
1. Mounting the Board Locate the unit inside a UL Listed NEMA 1 enclosure (such as a BASE LVPC Low Voltage Power Cabinet). Drill or punch
four 0.187" diameter holes (3/16”) to match the four corner holes in the printed circuit board. Push the nylon standoffs supplied into each hole and snap
the PCB module into place. Mounting with double-sided tape is not recommended.
2. Transformer Wiring See Transformer Selection above. Connect Transformer output wires to the two Transformer
AC
terminals.
3. DC Output Setup Set the Output Voltage Switch for the desired output - 12 or 24 VDC. With no load or battery wiring connected, turn on the AC
power source. The AC and DC green LEDs will light. Next, measure the voltage at the DC Output terminals with a voltmeter. The output voltage is
factory set to approx. 13.5 vdc or 27.0 vdc - ideal settings for charging batteries. However, if a field adjustment is desired, use a small screwdriver to
slowly adjust the output voltage at the potentiometer labeled
ADJ
. (If no batteries are being used - adjust down to 12 vdc or 24 vdc). Then turn off the
AC power source before proceeding with the installation.
4. Power Monitor Setup and Fault Relay Ouput Terminals Set the Option DIP Switches for the desired Power Monitor Options.
Installation Instructions
Install in accordance with applicable sections of the National Electrical Code and other State or Local Regulations.

WARNING
* * *
Turn off all power feeding the module terminals before installing, servicing or changing any switch settings, wiring, battery
or fuses. Failure to observe this warning may cause electrical shock hazard or may damage internal or external circuit
components. Various components of the unit will become hot during normal operation of the unit. Locate the unit away
from cabling or other objects that may be affected or damaged by this heat dissipation. Use caution while working near the
unit during normal operation - components can be hot enough to cause serious burns.

The Fault Alarm Relay is energized when no selected fault condition exists. The relay de-energizes and the Fault LED flashes when one or more
selected Fault Conditions are present. Terminals of the relay contacts are labeled for when the relay is in Alarm. The ST terminal is a Spare Terminal
that can be used as an easy splice point for an end-of-line resistor when monitoring the fault relay with a supervised circuit. Contact Rating is 2 Amps.
5. DC Output Wiring Connect output wiring to the DC OUTPUT terminals. Observe and verify correct DC polarity before powering the unit.
6. Battery Wiring Maximum standby batteries - 20 Ampere Hours. Connect battery wiring to battery terminals of the Power Supply first. Observe
and verify correct DC polarity before proceding to next step. Incorrect polarity will blow the
