APMxxxx Series User's Manual
10.38 Configuration – Alarm Settings – System
These settings allow various alarm categories to be disabled. Note that disabling an alarm category only suppresses activation
of the relevant alarm relays. For example if Tx Power alarms are disabled, the Tx Power alarm relay, and the Summary alarm
relay will not activate when the Tx Forward power level is outside the configured limits. However, the alarm status LEDS will
continue to operate normally, and the user interface will still display the relevant alarms.
VCO alarms:
When selected, a VCO alarm is raised when either of the APM unit's VCOs fail to frequency lock.
Tx Power alarms:
When selected, this alarm occurs when the Forward Power level for a Tx channel is outside the configured Min & Max power
alarm limits or when the Combiner Insertion Loss exceeds the configured alarm limit.
Tx VSWR alarms:
When selected, this alarm occurs when the VSWR for a Tx channel is greater than the configured limit.
