User & Technical Manual
Rev. 1.5 - 08/02/06
• If the audio of the aired exciter is still in alarm status on the elapsing of the aforesaid
time interval, the control unit checks if the audio of the exciter on the dummy load
is regular. In this case the changeover between the exciters is performed.
Observe the following differences as compared to the case in which power is missing:
•
The management of the "Audio alarm" signals is not active during the start-up
phase and during the switching phase from OFF to ON, but only when the exciters
are working in automatic.
• In the standard configuration, the aforesaid sequence continues until the audio
signal associated with one of the exciters becomes regular again. In the "N+1"
configuration, the switching attempt is performed only twice, after which the
PJ5KPS enters the fault status.
• An Audio Alarm output is provided on the parallel interface: this signal is activated
(with no delays) when the audio of the exciter that is currently on air is in alarm
status.
5.5 Protection and alarms
The PJ5KPS contains a complete protection and alarms system, both at the individ-
ual modules level and at the control unit level.
The modules are fitted with a micro-processor-based system that manages any
malfunctions locally. The associated information is communicated to the control unit
for displaying and storing the events and for the centralized management of the events
that require it.
Certain LEDs of the PJ5KPS panel are dedicated to the management of the alarms:
LED
Description
WARNING
This LED indicates a warning (something is not correctly working, but
the amplifier is still working)
FAULT
This LED indicates a fault (the amplifier is shut off, the operator’s
intervention is required)
WAIT
This LED indicates the wait status (the amplifier is temporarily off, it will
be restarted as soon as the reason that keeps it from working will be
removed, or after a fixed amount of time depending on the reason of the
intervention of the protection system)
The ALARM RESET button is used for resetting the alarms and restarting the machine.
A complete description of the alarms and protection system is given in chapter 7.5.
