Status Indicator RAPs
Check the connectors and harness between PJ553 and PJ601. Repair the harness
as necessary,
REP 1.1 .
The +24V and +5V supplies are good. Go to SCP 5 Final actions.
Go to WD 12.6. +24V is available at PJ601 between pins 4 and 6.

Go to the
12-310-00-171, 12-312-00-171, 12-313-00-171 Docking and Interlocks RAP.
The +24V and +5V supplies are good. Go to SCP 5 Final actions.
HVF PWB and BM PWB LEDs
Figure 1 shows the LED’s on the HVF PWB.
Figure 1 LEDs on the HVF PWB
The LEDs are:
• LED 1 - red. Not used.
• LED 2 - red. Not used.
• LED 3 - red, flashing. This indicates the functioning of the CPU. When flashing at 2Hz,
(every 1/2 second), the software is running normally. When flashing at about 1/4Hz,
(every 4 seconds), this indicates that the software is encountering a code problem and a
possible software upgrade is needed. If this LED is OFF, the CPU does not function and a
new HVF PWB is needed.
• LED 4 - red. Not used.
• LED 5 - red. Not used.
• LED 6 - red. Not used.
• LED 7 - red. Not used.
• LED 8 - red, steady. This indicates that the HVF top cover, front door and docking inter-
locks are all closed and +24V is available at the HVF module.
• LED 9 - red, steady. This indicates that the +5V supply is present in the HVF module.
Figure 2 shows the LED’s on the BM PWB.
Figure 2 LEDs on the BM control PWB
The LEDs are:
• LED 1 - red, steady. This indicates a fault or other abnormal status.
• LED 2 - yellow, flashing at about 1Hz. This indicates that the software is operating in nor-
mal mode. In other modes, e.g., software downloading, the flashing rate is higher.
• LED 3 - orange, steady. This indicates either:
– that the tri-folder front door and top cover interlocks are closed, and +24V is avail-
able to the BM module or, if the tri-folder in not installed;
– that the interlock cheater is present in PJ553 on the BM control PWB the logic
cheater is present in PL563 on the BM control PWB.
• LED 4 - orange, steady. This indicates that the +24V supply is within voltage and current
limits, and that the power limiting circuit has not been active for over a set time limit.
• LED 5 - blue, steady. this indicates that the +5V supply is present in the BM module.
