If the AC LED is off, it indicates there's no AC power. You should check the AC power source to ensure it's properly connected and functioning.
What to do if horn, horn strobes, or strobes do not synchronize on Wheelock Power Supply?
If your horn, horn strobes, or strobes aren't synchronizing, it could be due to improper MODE selection or incompatible appliances. Verify the MODE selection and ensure that the appliances are the correct type for synchronization. If in IN>OUT MODE, check the input appliance (DSM, SM, or PS-12/24-8MP).
Why is the DC LED off on my Wheelock Power Supply?
If the DC LED is off, this indicates that there is no DC output. To resolve this, check the wiring to the AC power source.
What to do if CLASS “A” circuit is not functioning properly on Wheelock Power Supply?
If a CLASS “A” circuit isn't functioning correctly, the MODE selection or SW9 settings might be incorrect. Ensure the MODE selection is identical for each Class “A” output circuit. Remember that Class “A” OUT1 uses outputs 1 and 3, while Class “A” OUT2 uses outputs 2 and 4. Also, check that SW9 POS 1 and POS 2 on the board are in the “ON” position.
What to do if CLASS “B” circuit is not functioning properly on Wheelock Power Supply?
If a CLASS “B” circuit is not working as expected, the MODE selection or SW9 settings are likely incorrect. Check SW9 POS 1 and POS 2 on the board and ensure they are in the “OFF” position.
What to do if INP1, INP2 LED’s do not light in ALARM on Wheelock Power Supply?
If the INP1 and INP2 LEDs do not light up during an alarm, it means there is no input signal on terminals IN1+IN1- and IN2+IN2-. Check the input and input wiring to resolve this issue.
What does it mean if GND FAULT LED ON on Wheelock Power Supply?
If the GND FAULT LED is on, it indicates a ground fault. Check the output circuits to resolve the issue.
What to do if OUT1, OUT2, OUT3, OUT4 LED's are on during standby on Wheelock Power Supply?
If the OUT1, OUT2, OUT3, and OUT4 LEDs are on during standby, it indicates a trouble on the output. Check the output supervision voltage and the output EOLR (End Of Line Resistor).
How to fix no audible output in WHEELOCK SYNC MODE on Wheelock Power Supply?
If there is no audible output in WHEELOCK SYNC MODE, it could be due to no input to IN2+,IN2-. Check Example 13 and 14 for proper input connections.
