The DC Power Supply has a green LED that dims or
goes out when 24v DC is not being output properly. If
the light is out verify the incoming voltage between L
and N and make sure the red switch on the side of
the power supply and the unit voltage match. Once
the supply is confirmed, detach the -V and +V
terminals and reset the power to the DC Power
Supply. The LED should come back on at full strength.
If it does not, Disconnect the power from the unit,
open the power supply and check the fuse. If the fuse
is ok, nothing is hooked to -V or +V and the voltage
switch and input at L and N all match the rating plate,
replace the supply. If the LED came on when the
power was reset, reattach the wires one set at a
time. If the light goes out or dims while a wire is
being placed, note the wire and refer to the diagram
to find where the wire leads to find the short. If all
the -V and +V wires are replaced and the LED remains
lit, Operate the components of the unit, using
Diagnostic Output, while watching the green LED.
Note when the LED goes out or dims, and repress the
button that caused it. On the relay board as that
button is pressed, a Red LED will Light, indicating the
active relay and output. For Example if the red LED
D32 corresponded to the power supply light going
out, the output to J20.7 should be the cause. Verify
this by pulling the J20 connector, resetting the supply
and reactivating the Diagnostic Output Button
pressed earlier. If confirmed check the J20.7 circuit
for the short.
