A load alarm can be generated if the status of the sequence is different to the status input of the referring load (stage-off alarm) or the referring alarm input is active.
The stage-off alarm can be enabled for each load individually. To enable the stage-off alarm, the referring parameter “delay status alarm load x” must be set to a time larger than “0”. The stage-off alarms are delayed by parameters ALM-01, ALM-02 and ALM-03.
The alarm input can be disabled by fixing the input to “0” per default.
When an alarm occurs, the corresponding load command will be switched off. The next load of the sequence is started. The failed load will not be used in the sequence until it has been reset (manual or automatic reset).
The load will be commanded with its original sequence number again when the requested number of loads will increase, or sequence rotation becomes active and the load outputs will be switched. The failed load is not started when the alarm returns to normal and the alarm is reset.
