GDM Description
Event Description
Three things can produce this
Bypass not ready
warning:
1. The FSB spring is discharged.
2. There is an under voltage on the
FSB Interface Board. LED 3 will turn
off while the under voltage is
present and the Interface Board will
autonomously close the FSB. The
master will detect the un-
commanded closure via the FSB
aux contacts and will trigger event
325.
3. The SOR test device in the FSB
enclosure has detected the ACB
close coil resistance is out of
tolerance.
When this warning is present LED
5 on the utility disconnect
interface board (see Table 7-11)
and LED 7 on the SCR firing board
will be off (not illuminated) . The
FSB will close while this Warning is
present even if the PCS100 UPS-I
is ON LINE. This warning is
masked for the first 6 seconds it
is active to allow time for the FSB
spring to charge.
Discharge -
The utility's transient voltage
transient
threshold has been breached and
the PCS100 UPS-I has:
(1) begun supplying the load from
the PCS100 UPS-I's Energy
Storage and
(2) disconnected the load from
the utility.
Discharge - test
A test discharge has been
performed using parameter 622
Test Activate.
Module Charger
The Module Charger has changed
state (on/off).
Many contactor
The Inverter pre-charge contactor
activations
is switching too often.
Sequence
A module has detected that its
Mismatch Error
phase sequence differs from the
Auxiliary Master Module.
Discharge -
The utility frequency has
frequency
breached its threshold and the
PCS100 UPS-I has:
(1) begun supplying the load from
the PCS100 UPS-I Energy Storage
Recommended Action
(1) View the window on the
front of the ACB to see if the
operating spring is charged.
(2) View the FSB Interface
PCB LED3 (ULVO). If it is off
the PCB has detected a low
DC voltage supply and has
commanded
the
ACB
close.
Check
the
power supply to the FSB
interface board is above the
threshold (23Vdc)
(3) View the Fault LED on the
SOR test unit.
