The exchange of the exciters is assisted from the software, that is when the
commutation is carried out , the interlock comes systematized in the correct way
independently from like they were. The interlock could be modified also manually in
case of necessity.
5.4 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 funzione dello stato
dell’automatismo del PJ5KPS, il comportamento della macchina sarà diverso. In
questo capitolo sono descritti i diversi casi.
In function of the state of the PJ5KPS automatism, the behavior of the machine will
be various. In this chapter are described the different cases.
5.4.1 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 PJ5KPS in automatic mode when you are not performing maintenance
operations.
5.4.2 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.
