Check OUT1 terminals for good connections. Check NAC circuit wiring for continuity. Check NAC circuit for 10K Ohm EOLR.
What to do if I'm having battery trouble with my POWERPATH PS-8?
Check the battery wiring and terminal connections. If needed, replace the batteries. Alternatively, remove the batteries and check the voltage across the terminals with a DC voltmeter. It should be 26.5VDC or higher. If not, the battery charger section has failed, so replace the PC Board. If the voltage is present, replace the batteries.
What should I do if I encounter a system trouble with my POWERPATH PS-8 Power Supply?
Check the Coded Trouble LED Indicators and the Ground Fault LED. Repair any problems indicated. If no indication is observed, replace the Control PC Board.
How to locate a ground fault in POWERPATH PS-8 Power Supply?
Shut off AC Mains Power to the unit. Open the cabinet door. Press and hold SW5, the Ground Fault Locator Switch, for 5 seconds, then release it.
What to do if I have battery charger trouble with POWERPATH Power Supply?
Remove the batteries from the terminals. Using a DC voltmeter, check the voltage across the terminals. The voltage should be 26.5VDC or higher. If the voltage is not present, the battery charger section has failed. Replace the PC Board. If the voltage is present, replace the batteries.
What to do if I have processor trouble with POWERPATH Power Supply?
Disconnect DC and AC voltages from the power supply PC board. Wait 10 seconds, then reconnect. If the problem persists, replace the PC board.
How to resolve NAC Output 1 current limit on POWERPATH PS-8?
Reduce the number of NAC Appliances on Output1.
How to fix NAC Output 2 open on POWERPATH Power Supply?
Check OUT2 terminals for good connections. Check NAC circuit wiring for continuity. Check NAC circuit for 10K Ohm EOLR.
