7.2 DISPLAY AND MESSAGES

7 TESTING AND TROUBLESHOOTING

7

•

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 Power Management to cor-

rect this problem.

•

NOVRAM FAILURE

: After the SPM writes data to its non-volatile memory (E

2

PROM), the CPU immediately

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 Power Management.

•

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 Power Management.

•

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 Power Management 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 Power Management 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!

.

DO NOT DEFEAT THE MOTOR RESTART PROTECTION PROVIDED BY THE SPM BY SWITCH-
ING THE CONTROL POWER ON AND OFF. THE ABOVE ACTION RESETS THE STALL TIME
COUNTERS WHICH DEFEATS MOTOR PROTECTION FROM FREQUENT RESTARTS.

NOTE

CAUTION
