1
S, I
F
Module Start
Failure
The module failed to start
because of an error with one of
the following:
(1) The configuration ID does not
match the hardware ID DIP
switch.
(2) NVRAM
(3) FPGA (Field Programmable
Gate Array)
Check the configuration ID

F
Desat
IGBT Desat Detection
Power down and restart
PCS100 UPS-I.
If the fault does not clear
replace the relevant
Inverter module.
3
I
F
Desat Cooling
Time
A reset was attempted too soon
after a Desat fault (event 02).
Wait for 30 s before
pressing Reset.

LVDC PSU Voltage
Low
(1) The PCS100 UPS-I has powered
down. If intentionally powered
down this warning is normal, and
no resolution is required.
(2) The LVDC power supply in the
Auxiliary Master Module has
failed.
(1) Check LVDC (26 V)
power supply is 26.5-27 V
(2) Check fuse F1 on the
Auxiliary Master Module.
(3) Check for
approximately 200 VAC on
P76.
(4) Replace the relevant
Auxiliary Master Module.
5
I
F
Interlock Error
The software has detected an
error in IGBT gate triggers. Two
of the IGBTs (Insulated Gate
Bipolar Transistor) from the same
bridge are turned on at one time.
Only one should ever be turned on
at any one time.
Replace the faulty Inverter
module.
6
S, I
F
SPI Watchdog
Error
There is an SPI (Serial Peripheral
Interface Bus) watchdog error.
Ensure all communication
cables are connected and
not damaged. Replace any
damaged cables. Replace
the module reporting the
Fault.
7
S, I
F
Combined FPGA
Fault
There is a generic FPGA (Field-
Programmable Gate Array) fault.
Check all communication
cables.
8
I
W
DC Bus
Overvoltage
The over voltage limit is set by
the hardware in the Inverter
module. Event code 148 “DC bus
high” should occur before this
fault and open the Coupling
Transformer circuit breaker.
Power down and restart
PCS100 UPS-I.
9
I
W
DC Bus Voltage
High
The DC Bus voltage is high.
Wait until the DC voltage
has returned to normal.
