F-10 6880493G02-C July 2000
E_INTERNAL_DETECTOR_NOT_CALIBRATED
The Internal Power Detector has not been calibrated.
The RF-O! transmitter validates detector calibration at
startup, or when Power Control is changed from
Disabled to Enabled. Internal and External Detector
Calibration values are stored in the Exciter Serial
EEPROM.
Major
ON SITE: Calibrate Internal Detector
using the proper calibration
procedure.(RFO FIPS: a 71).
E_INTERNAL_FOWARD_POWER_LOW
Power Output is below the limit on the Internal Forward
Power Meter during an FM transmission. The limit is set
by writing to Parameter 141. If you do not care to
monitor this alarm, set Parameter 141 to its maximum
value of 600 (Watts).
NOTE: When running RF-O! transmitter 1.2.2, it is
normal to log this error while running the Automatic
Carrier Null procedure (RFO FIPS: a 74), which
operates at a power output between 0 and 5 watts.
Major
Check station output power level using
RFO FIPS: a 80.
If condition persists, contact Motorola.
E_INTERNAL_REFLECTED_POWER_HIGH
Power Output is above the limit on the Internal
Reflected power meter. The limit is set by writing
Parameter 143 (RFO FIPS: w 143 x) 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.
Critical
This error normally indicates a possible
short or open circuit between the Internal
Detector and the antenna. Check all
connections. Check station output power
level using RFO FIPS: a 80. Error could
possibly indicate a faulty Internal
Detector. If condition persists, contact
Motorola.
E_INVALID_AM_CONFIGURATION
This error occur during Power Control initialization,
during startup. There are two possible causes: (1)
There are no PA decks detected; (2) The current power
level was set out of range per the Power Chart.
Critical
Check PA configuration using RFO FIPS:
r 993. Set output power using RFO FIPS:
a 88 x y. If condition persists, contact
Motorola.
E_INVALID_CHAN_OFFSET
(formerly E_RFCC_INVALID_CHAN_OFFSET)
An invalid sub-channel offset was received from the
Plug-and-Play Control Command.
Major
If the error persists, save the error log and
contact Motorola.
