replace the current sense board or AC
precharge board. See the hardware
service manual, publication 750-

14005 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 VDC. This power
supply provides power to the power layer
interface board or DC precharge board (if
present).
Verify DC bus is present on the Lx
power module via the hardware
testpoints. If so, replace the Ln PIB.
See the hardware service manual,
publication 750-TG100, for the
replacement procedure.

14006 Precharge Fault
Precharge Fault. The DC bus voltage was
less than the configured threshold 1.5
seconds after precharge was
commanded.
Ensure the converter is properly sized
for the application. Verify total external
bus capacitance does not exceed
specification. See publication DRIVES-
AT005.

14007 MCB CL BayOTmp
MCB Failed to Close or Wiring Bay
Overtemp. Two things can cause this
fault:
• The main circuit breaker (CB1) in the
AC precharge has failed to close
when commanded.
• 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. Investigate causes
for over-temperature in these bays.
Check the circuit breaker. Check the
Predictive Maintenance parameters for
the MCC. Check the enclosure filters
and fans. Check the thermal sensor
harness for the input bay or entry wiring
bay or bypass jumper. See the Service
Manual, publication 750-TG100, for the
replacement procedure. Check the
Predictive Maintenance parameters for
these fans. Check the baffling between
these bays and adjacent bays that can
be sources of heat.

14009 MCB Aux BayOTmp
MCB Aux Mismatch or Wiring Bay
Overtemp. Two things can cause this
fault:
• The auxiliary contact on the main
circuit breaker (CB1) in the AC
precharge is not functioning properly.
• The temperature in the input bay or
entry wiring bay has risen too high.
This condition can only cause the fault
after the drive or bus supply has
completed precharge. Investigate causes
for over-temperature in these bays.
Check the circuit breaker. Check the
enclosure filters and fans. Check the
thermal sensor harness for the input
bay or entry wiring bay or bypass
jumper. Check the baffling between
these bays and adjacent bays that can
be sources of heat. See the Service
Manual, publication 750-TG100, for
procedure.

14010 240VAC Loss Flt
240 VAC Loss Fault. The 240 VAC supply
voltage fell below the specified minimum
voltage level of 154V AC during the pre-
charge cycle or while the main circuit
breaker (MCB) is closed. See parameters
14:1112 [ACP0 PwrSup Vltg] and/or
14:1122 [ACP1 PwrSup Vltg].
Verify that the 240 VAC input is within
specification. If configured with a
control transformer:
• Inspect connections.
• Inspect primary and secondary
fuses.
• Verify that the primary transformer
connections are tapped for the
proper input voltage.
See the hardware service manual,
publication 750-TG100, for the system
schematics.

240 VAC Over Voltage. The 240 VAC
supply voltage rose above the specified
maximum voltage level (283V AC). See
parameters 14:1112 [ACP0 PwrSup Vltg]
and/or 14:1122 [ACP1 PwrSup Vltg].
Verify that the 240 VAC input is within
specification. If configured with a
control transformer, verify that the
primary transformer connections are
tapped for the proper input voltage. See
