Management of the exciters
The control unit can perform the automatic changeover between exciters if one
malfunctions. The Manual LED on the panel indicates, when it is lighted up, that the
automatic changeover function is disabled. In order to enable it, click the EXCITER
CHANGEOVER button and check that the LED turns off.
In function of the state of the PJ10KPS-CA automatism, the behavior of the machine
will be various. In this chapter are described the different cases.
8.6.1
Start-up from power-on with exciters in manual mode
When powering on the machine with the exciters in manual mode, the apparatus
does not perform any check, both mute RF signals are active and the changeover
relay remains in standby status. Use the exciters menu to activate an exciter.
NB
This is why, if the transmitter is left in manual mode, any momentary power failure
will cause the transmitter to be inactive when turned on again. Therefore it is
advisable to leave the PJ10KPS-CA in automatic mode when you are not performing
maintenance operations.
8.6.2
From OFF to ON with exciters in manual
When switching from OFF (or STDBY) to ON with the exciters in manual mode,
the apparatus does not perform any check and the exciter that is currently set to
on air is the one that is aired.
If the mains signal is not OK, the exciters turn off automatically.
If the maximum drive power is exceeded during operations, the PJ10KPS-CA is
set to fault status and power supply is cut to the exciters. A message in the alarms
menu signals this fault.
When the apparatus is set to STDBY, the mute RF signals of the exciters are not
activated and may be modified by the operator.
When the apparatus is set to EXT INT or AUX INT, the mute RF signals of the
exciters are not activated and may be modified by the operator.
