Troubleshooting
6.12 Power Supply Controller Faults
The following paragraphs give a detailed description of all faults associated with the
PS Controller Board. A quick reference of these faults is given in Table 6-3 at the
end of this section.There are two types of power supply faults:
•
Critical
•
Non-Critical
Critical faults will shut the power supply off, while the non-critical faults give a
fault indication on the front of the controller and are written into the fault log.
6.12.1 General Power Supply Troubleshooting
Since each PS Controller can control 2 supplies, a first line of defense against most
types of power supply faults is to swap the cables (ribbon cables W11 and W12) on
the back of the PS controller board to see if the problem follows the controller or is
actually a power supply problem. If the controller is at fault, the problem will move
to a different supply (each supply has its own ID and will therefore show up as the
same supply no matter what controller port they are connected to). The only other
easy troubleshooting would be to swap out the controller card if a spare is available.
This also requires setting the ID switches on the new PS Controller board to the
same as the one being replaced and possibly moving the firmware from the old
board to the new one. See “Replacing the PS Controller Board” in Section V,
Maintenance and Alignments.
If the transmitter has the dual PS Controller option then the cables can be swapped
between the 2 controller cards (W11 would be attached to PSC #1 and W12 would
be attached to PSC #2 before swapping but this is not critical). If the problem moves
to a different power supply then the controller is bad and should be replaced.
6.12.2 Critical Power Supply Faults
The following is a list of critical Power Supply faults with a brief description and
where the status of these faults can be found in the Diagnostics Display System.
Under Critical Fault conditions the power supply is going to be turned off. The only
way to reset a critical fault is by pressing one of the ON buttons on the front panel,
which will send out a TX_RESTART command to all of the controller boards. The
system will try to re-initialize and come back up to full power. If the faults are still
present, the transmitter will simply fault off again.
