7.2 Alarms/events list
There is an “Alarms Management” module.
To check the alarm conditions physical and logical digital inputs are used.
Each input status is sampled and then the condition is logically drawn by a combinato-
rial network, to define if the alarm or signal are active.
Response time is 100ms minimum.
This module is repeatedly performed with the same priority as the ALC management, in
order to constantly monitor the occurrence of alarm causes, and thus to operate in good
time.
In a register is stored the recent events sequence, with date and time of activation.
The possible alarms/events list is:
Alarm/event Description
“000 CORRECT WORKING”
It indicates the correct functioning. In any case
the “On air” event takes the precedence.
“001 SYSTEM RESET”
It indicates that the alarm reset is in progress.
All the alarms stored and no longer active are
removed from the list.
“002 EEPROM CHKSUM ERROR”
It indicates that the persistent data in mem-
ory are no longer reliable and the machine is
reconfigured with the default parameters.
“003 BLOCKED”
It indicates that the machine is blocked after
6 attempts to restore every 5 minutes for 3
times, coming in an hour break and repeating
the procedure within 24 hours. At the end of
24 hours is required a reset by the user to en-
able the apparatus restart.
“004 STOP”
It indicates that the device is in stand-by,
ready to start without alarms.
“005 -3dB CARRIER”
It indicates that the device is providing at
least 3dB less power than the set target, at le-
ast one minute in boot or five seconds steady.
“006 HIGH REF PWR”
It indicates the presence of a level of output
reflected power too high, which means tur-
ning off the equipment in three block out.
“007 MIN 12V”
It indicates that the negative reference
voltage is changed and prevents the proper
functioning of protections. Stopping in three
blocks out.
“008 RF AMP. FAULT”
It indicate a fault, on one or more RF modules.
“009 RF AMP. FAULT DERATING”
It indicate a fault, on one or more RF modules,
which implies a reduction of total maximum
power supplied.
“010 RF THERMAL DERATING”
It indicates a too hot temperature on the RF
modules, which implies a reduction in maxi-
mum power output.
“011 RF OVER TEMPERATURE”
It indicates a maximum operating temperatu-
re overcoming, resulting in shutdown of the
machine in three blocks out. This protection
occurs in extreme cases where the mecha-
nism Derating was not enough to return to
normal temperature values.
“012 PSU FAULT”
It indicates a power supply malfunction.
“013 PSU CURRENT DERATING”
It indicates the power supply overhead, which
determines the decrease in output power.
