User & Technical Manual
Rev. 1.5 - 08/02/06
If the mains signal is not OK, the exciters turn off automatically.
If the maximum drive power is exceeded during operations (> 35W), the PJ5KPS 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.
5.4.3 Automatic changeover
When the PJ5KPS is in the exciter automatic changeover mode, the power emitted
by the on air exciter is checked constantly. If at any time the on air exciter is no longer
good (i.e. power drops to below the preset level), the apparatus is kept operational
whereas the exciter connected to the internal Dummy Load turns on. If the latter one
is good (i.e. it is capable of supplying the required power), then the two exciters are
changed over. Instead if the alternative exciter is not good, no changeover takes
place, the control unit commands the mute RF of the exciter to Dummy Load, it waits
120 s. and repeats the attempt. This procedure is repeated indefinitely until one of
the two exciters is considered to be good.
During the whole length of time during which there is no good exciter, the PJ5KPS
keeps the WAIT LED on for signaling this status.
Each exciter is fitted with its own mute RF. On being commanded, the piloting signal
must return to zero within 3 seconds at the most. If this does not occur, the fault is
recorded by an error message that is entered in the alarms menu.
If the mains signal is not OK, the exciters turn off automatically. If the piloting power
exceeds the limit during operations, the PJ5KPS is set to the FAULT status and the
power supply of the exciters is turned off. A message in the alarms menu signals the
fault. Keep in mind that the operator's intervention is required to exit from the FAULT
status.
If the MAINS signal coming from the bus is not OK, the exciters are all turned off. As
soon as the MAINS signal is regular again, the evaluation cycle of the exciters begins
(see 5.4.4).
When the apparatus is set to STDBY, the mute RF signals of the exciters are activated
and as such both exciters are inhibited. If the ON key is pressed, the system re-
evaluates both exciters in the same manner as in the procedure from OFF to ON
(see 5.4.4).
