Alarms and Error Messages RF-Orchestra!™ Transmitter Installation and Operation
F-8 6880493G02-C July 2000
E_FM_NOT_ALIGNED
(See “E_AMPLITUDE_NOT_ALIGNED” )
The amplitude alignment parameters stored in the
Exciter EEPROM are invalid. Major
The Power Amplitude Alignment must be
performed (RFO FIPS: a 76) at the site.
Power Control must be disabled (RFO
FIPS; w 992 0), prior to performing the
Amplitude Alignment.
Use RFO FIPS: a 83 (Station Status) to
determine Alignment/Calibration status.
E_FREQ_OFFSET_ERROR
An invalid/unsupported Sub-channel was received in
the Plug-and-Play Control Command Major
If errors persist, save error log and
contact Motorola.
NOTE: This is a Plug-and-Play Error.
Transmitter was Disabled for 2 seconds,
and DSP buffers were flushed.
E_HIGH_AMBIENT_TEMP_CUTBACK_ALARM
The transmitter ambient temperature has exceeded the
Ambient Temperature Cutback Threshold (Parameter
3001). By default, this value is 45 (degrees C). Ambient
temperature is measured at the temperature sensor on
OCM. Major
Verify proper calibration of OCM
temperature sensor. Read current
ambient temperature (RFO FIPS: r 1026).
If ambient temperature reading differs by
more than 3 degrees from the transmitter
site room temperature, the sensor is not
calibrated correctly, and should be
calibrated. If site temperature is above 45
degrees C (113 degrees F), station is
operating properly. If errors persist, save
error log and contact Motorola.
E_HIGH_AMBIENT_TEMP_SHUTDOWN_ALARM
The transmitter ambient temperature has exceeded the
Ambient Temperature Shutdown Threshold (Parameter
3002). By default, this value is 60 (degrees C). Ambient
temperature is measured at the temperature sensor on
OCM.
Major
See
E_HIGH_AMBIENT_TEMP_CUTBACK_
ALARM.
If transmitter site room temperature
exceeds 60 degrees C (140 degrees F),
RF-O! is operating properly. If errors
persist, save error log and contact
Motorola.
E_HIGH_EXT_WM_VSWR_ALARM
RF-O! transmitter disabled the transmitter due to a
VSWR (Voltage Standing Wave Ratio) reading of
greater than 3.0 (Reflected Power is greater than one-
fourth of the Forward Power) at the External Detector.
Critical
