3.2 Alarms/events list
There is an “Alarm management” module.
In order to check the alarm conditions, physical and logical digital inputs are used.
The status of each input is sampled and the condition is then logically processed by a
combinational network so as to establish whether the alarm or signalling is active.
The minimum intervention time is 100ms.
This module is repeatedly performed with the same priority as ALC management, so
as to constantly monitor the alarm cause onset and therefore to intervene within the
required time frame.
A log stores the sequence of the last events generating alarms with the date and time
of activation.
3.2.1 Control unit alarms/events list
Alarm/event Description
“000 CORRECT WORKING”
This indicates correct equipment operation.
The “On air” event has higher priority.
“001 SYSTEM RESET”
This indicates that the alarm reset is in
progress. All stored and inactive alarms are
removed from the list.
“002 EEPROM CHKSUM ERROR”
This indicates that the stored data is not relia-
ble any longer and the machine is reconfigu-
red according to the default parameters.
“003 BLOCKED”
This indicates that the machine is blocked
after making 5 restore attempts. the user
must reset in order to allow the equipment to
restart.
“004 STOP”
This indicates that the equipment is in stand-
by mode and is ready to start without alarms.
“005 -3dB CARRIER”
This indicates that the equipment has been
delivering power at least 3dB less than the
target set, for at least a minute in start-up and
5 seconds of normal operation.
“006 HIGH REF PWR”
This indicates that the level of reflected
output power is too high, meaning that the
equipment will turn off in three block out.
“007 RF THERMAL DERATING”
This indicates a too hot temperature on ampli-
fiers, which implies a reduction in maximum
power output.
“008 RF OVER TEMPERATURE”
This indicates a maximum operating tem-
perature overcoming for RF amplifier stage,
resulting in shutdown of the machine in three
blocks out. This protection occurs in extreme
cases where the mechanism Derating was
not enough to return to normal temperature
values.
“009 EXTERNAL INTERLOCK”
This indicates that interlock is active.
“010 ON AIR”
This indicates that the device is functioning
properly and is being transmitted.
“011 POWER UP”
This indicates that is being inserted in the
storage an alert regarding the restart of the
device.
“012 POWER DOWN”
This indicates that is being inserted in the
storage an alert regarding the shutdown of
the equipment.
“013 EXCITER EXCHANGE”
This indicates that there was an exchange of
the exciter.
“014 EXCITER SYNC COAX”
This indicates that an assessment of relay
position was made.
“015 INCORRECT COAX WORK”
This indicates that there is a relay problem.
“016 ON LOCAL SLAVE AMPLIFIER”
This indicates that one or more amplifiers are
in LOCAL mode.
