Int. Serial Fail
SD: Exciter
RI:
Exciter Fail
This alarm occurs when there is no
communication with the remote interface PWB
for 2 seconds. See
Low B+
Voltage
SD: AC Mains
RI:
Low B
+
This alarm is triggered if the B
+
voltage falls
below its factory-set threshold. See
Low Backup
Battery
RI:
Memory Battery
Alarm
This alarm is triggered when the voltage of the
backup battery has fallen below an acceptable
level. See
LVPS Fault
SD: Low Voltage Power
Supply
RI:
LVPS Fail
The +24 V, +15 V, -15 V and +5 V power
supplies are monitored. This fault is reported if
one or more of these voltages exceeds its
specified limits. See
Mod Driver
Fail A
SD: Exciter
RI:
Exciter Fail
This fail is reported if the modulator drive on
exciter A is inoperative due to a high duty cycle.
See
Mod Driver
Fail B
SD: Exciter
RI:
Exciter Fail
This fail is reported if the modulator drive on
exciter B is inoperative due to a high duty cycle.
See
Mod.
Protection
SD: External Alarm
This fail is reported from the remote interface
PWB to prevent overmodulation. See
PDM Drive
Fail
SD: Exciter
RI:
Exciter Fail
This fail indicates that the PDM drive on the
active exciter is inoperative due to a low duty
cycle. See
PM Fault A
SD: IPA/PA
RI:
Power Mod Fail
This alarm is triggered when power module A
reports a fault. See
.
PM Fault B
SD: IPA/PA
RI:
Power Mod Fail
This alarm is triggered when RF power module
B reports a fault. See
.
PM Fault C
SD: IPA/PA
