WARNING: Disconnect primary power prior to servicing.
ZX Series
Appendix A - FM Web Remote Option
STATUS Operational status of amplifier chassis. [ON/OFF/FAULT/???]
[ON] = Transmitter is switched on.
[OFF] = Transmitter is switched off.
[FAULT] = Transmitter is switched on but has active faults.
[???] = Web remote is awaiting input of a valid password or has lost serial data
link.
MODE Transmitting mode of amplifier chassis. [FM/FMHD/HD/SL]
[FM] = analog FM modulation
[FMHD] = combined FM+HD mode
[HD] = digital HD Radio mode
[SL] = Split Level Combining mode
AMBIENT TEMP Ambient temperature in degrees centigrade. Sensor is on transmitter controller
PCB on reverse of front door.
EXCITER Exciter currently on air as reported by Flexstar Main/Alt Switcher (981-0193-001),
when installed. [A/B]
If the main/alt switcher is marked as NOT installed on the configuration page,
exciter A is always reported.
EXCITER WATTS Exciter forward power in watts, obtained from DC sample supplied by exciter via
exciter interface cable.
PA FWD WATTS Forward output power of amplifier chassis in watts. Detector is on I/O PC board.
PA REV WATTS Reverse output power of amplifier chassis in watts. Detector is on I/O PC board.
PA VOLTS Drain voltage of PA modules in volts as reported from PA backplane boards.
PA AMPS Total current of PA modules in amperes, (final stage, no IPA) as measured on
controller board.
IPA AMPS IPA module current in amperes, as reported from IPA backplane board.
PA AMPS (1-8) PA module currents in amperes, as reported from PA backplane boards.
MAX PA TEMP Maximum PA module temperature in degrees centigrade, as reported from PA
backplane boards.
MAX LOAD TEMP Maximum combiner load temperature in degrees centigrade, as reported from
combiner load board in output assembly.
FAULT INDICATIONS
POWER LOW
(AGC NOK)
AGC has come unlocked due to failure of a PA, exciter, other module, or because
transmitter is switched off. (AGC is used synonymously with APC)
REVERSE
FOLDBACK
Power is being automatically reduced due to excessive RF reverse power (VSWR)
measured at output.
RESTARTS
EXCEEDED
Auto-restart circuit has locked out due to multiple unsuccessful restart attempts.
