Status LED Troubleshooting
Be certain that the power supply has been through the
Initial Checks
as outlined earlier in this section before
troubleshooting STATUS LEDs.
When any one of the STATUS LEDs illuminates, there is a fault condition that must be corrected in order for
the power supply to become operational.
See
Section 10 Wiring Diagrams
in this manual for reference.
1. INTERLOCK LED illuminated:
1.1 Door(s) to Remote RHF Console not completely shut.
This LED will extinguish when switches S1 and S2 located in
the RHF console are closed. The switches will close when
the RHF console doors are closed. If the doors are closed,
check pins, connectors and associated wiring for good
continuity from receptacle 1X1 to 2X1.
Repair and/or replace defective component(s), if necessary.
2. TRANSFORMER LED
illuminated:
2.1. Main Transformer T2 or one of the choppers is overheating.
This LED will extinguish when the main transformer (T2) is
operating in a normal temperature range (under 165° C)
and choppers CH1 and CH2 are also operating in a normal
temperature range (under 82°C).
• Check temperature switches (normally closed).
• Check pins, connectors and associated wiring to
temperature switches.
• Leave the fans running, and try restarting the unit after
one hour. If LED still illuminates, one of the choppers or
the main transformer may need to be replaced.
