7.2 DISPLAY AND MESSAGES
RUN-TIME FAULT: The CPU has calculated a series of values within a set time limit that are out of their valid
•
ranges. Power must be cycled to the unit to correct this error.
ROM FAILURE: A PROM checksum error occurred during self-test. Consult GE Multilin to correct this prob-
•
lem.
NOVRAM FAILURE: After the SPM writes data to its non-volatile memory (E
•
reads back the last value and compares it to what should have been written. If the two values are not
equal, the SPM displays this message. This generally indicates a problem with the CPU Board. The SPM
should be replaced.
RAM FAILURE: A RAM checksum error occurred during self-test. This error is sometimes cleared by cycling
•
power through the unit. Otherwise, consult GE Multilin.
FPGA FAILURE: The Field Programmable Gate Array has failed to configure during self-test. Power can be
•
cycled to the unit in an attempt to clear this error. Otherwise, consult the GE Multilin.
CHECK MX & TRP CIRCUIT: The motor is in a tripped state. Either the MX contacts are still open and the TRIP
•
relay is de-energized, or the TRIP relay is energized but the internal circuitry to sense this has failed.
MX or TRP FAILURE: The MX circuit or the TRIP relay circuit has failed.
•
COMM CARD FAILURE: The communications card has failed or was not present during power up or SYSTEM
•
TEST. A periodic display of this error occurs only if a communication card test was passed during power-up
and subsequently fails during normal operation. Only for units with the communications option.
•
WDT CKT FAILURE: The watchdog timer circuit has failed during self-test.
INCOMPLETE SETUP: The internal configuration information (not user selectable) has been lost and the unit
•
will not function. The SPM must be returned to GE Multilin for correction of this problem.
CALIBRATION REQD: The SPM has lost the calibration information stored in its non-volatile memory. The unit
•
must be returned to GE Multilin for correction of this problem.
•
FORCED WDT TRIP: The TRIP relay has been told to de-energize but is still showing as energized. In this
condition, the CPU forces a watchdog timer trip in an attempt to de-energize the TRIP relay.
See Users Manual: Consult the user manual for correction.
•
Press any key to clear a trip messages such as PWR FACTOR TRIP! or SQL CAGE TRIP!.
