peripherals (power layer interface board,
torque accuracy module, or DC
precharge board) has stopped
transmitting for 10 milliseconds.
Power down and then check the fiber-

12005 Power Supply UV
Power Supply Undervoltage. An
undervoltage event occurred in the local
(internal to the PIB) power supply. A
possible cause is the DC bus voltage,
which feeds the power supply, has
dropped below 400-v DC. This power
supply provides power to the power layer
interface board or DC precharge board (if
present).
Verify DC bus is present on the Mn
power module via the hardware
testpoints. If so, replace the Mn power
interface board (PIB). See hardware
service manual, publication 750-TG100
for PowerFlex 755T or publication 750-
TG101 for PowerFlex 755TS products,
for the replacement procedure.

12007 MCS CL BayOTmp
• MCS Failed to Close or Wiring Bay
Overtemp. Two conditions can cause
this fault:
• Condition 1: The molded case switch
(MCS) in the DC precharge has failed
to close when commanded.
• Condition 2: The temperature in the
input bay or entry wiring bay has risen
too high. This condition can only
cause the fault before the drive or bus
supply has completed precharge.
• Condition 1: Inspect the DC
precharge module and the thermal
sensor harness for the exit wiring
bay. Ensure MCS lockout device is
not closed. See the Service
Manual, publication 750-TG100 for
PowerFlex 755T or publication
750-TG101 for PowerFlex 755TS
products, for details.
• Condition 2: Check the enclosure
filters and fans. Problems with the
baffling between these bay and
adjacent bays can be sources of
heat.
