RF-Orchestra!™ Transmitter Installation and Operation Alarms and Error Messages
July 2000 6880493G02-C F-7
E_EXCITER_EEPROM_WRITE_FAIL
The OCM was unable to write data to the Exciter Serial
EEPROM using the SPI bus. The Exciter Serial
EEPROM contains the Internal and External Wattmeter
Calibration, and the Amplitude Alignment data
necessary for proper power output and leveling. This
error would only occur during Write to Exciter EEPROM
(RFO FIPS: a 72), Amplitude Alignment (a 76), or
Internal or External Wattmeter/Detector Calibration (a
71).
Major
Verify proper seating of Exciter and OCM
Module within the chassis. Clear error
logs, then reset OCM. Perform RFO FIPS
command which caused the error to
occur (a 72, a 76, or a 71). Error could
indicate possible Exciter, backplane, and/
or OCM module failure. If error persists,
save error log and contact Motorola.
E_EXCITER_FRU_FAIL_ALARM
Catastrophic Exciter Failure Detected. This error is
currently logged when the OCM repeatedly fails to lock
one or both of the synthesizers on the Exciter.
Critical
Check for proper installation of Exciter. If
problem persists, Exciter module should
be replaced.
E_EXTERNAL_DETECTOR_NOT_CALIBRATED
The external power detector has not been calibrated.
This check is performed when RF-O! boots.
Major
ON SITE: Calibrate the detectors using
RFO FIPS: a 71 x yyy and a reference
wattmeter.
E_EXTERNAL_FORWARD_POWER_LOW
Power Output is below the limit on the external forward
power meter during an FM transmission. The limit is set
by writing to Parameter 144. If you do not care to
monitor this alarm, set Parameter 144 to its maximum
value of 600 (Watts).
Major
Check station output power level using
RFO FIPS: a 80. Verify that all RF
connections are secure.
If condition persists, this error could
indicate a faulty external detector.
Contact Motorola.
E_EXTERNAL_REFLECTED_POWER_HIGH
Power Output is above the limit on the external
reflected power meter during an FM transmission. The
limit is set by writing Parameter 146 to the desired level
(less than one-fourth the FM Power Output setting of
Parameter 994).Beginning with RF-O! transmitter 1.2.2,
when this error is logged, and Power Control is
Enabled, the transmitter will become disabled. The
RF-O! transmitter must be reset to re-enable the
transmitter.
Major
This error normally indicates a possible
short or open circuit between the External
Detector and the antenna. Check all
connections.
Check station output power level using
RFO FIPS: a 80.
Error could possibly indicate a faulty
External Detector.
If condition persists, contact Motorola.
E_FFDS_INVALID_TX_MODE_REQUESTED
A DSP received an invalid DSP flush request.
Minor
If error persists, save error log and
contact Motorola.
