6.15 Power Supply Controller Faults
The following paragraphs give a detailed description of all faults associated with the PS
Controller Boards. A quick reference of these faults is given in Table 6-4 on page 6-50.
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.
6.15.1 General Power Supply Troubleshooting
Each PS Controller controls 2 supplies. Knowing the control distribution for the
controllers is very important when troubleshooting.
•
PSC#1 controls PS1 and PS4
•
PSC#2 controls PS2 and PS3
A first response to most types of power supply faults is to swap the cables on the back
of the PS controller boards 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 options at this point
are to actually swap the controller cards themselves or replace the suspected PS
Controller board. Swapping the PS Controller cards requires re-setting the ID dip
switches on each board. Swapping the actual cards is probably not going to help.
6.15.2 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 power supply will simply fault off again.
NOTE:
Since one power supply controller controls two power supplies, one of the power
supplies can be turned off, due to a fault, while the other one continues to operate
