•AlarmOperation
Lossofsignalalarms
The loss of signal alarm works with offset zero signals, e.g., -20 mA or
1- V. You program reset and setpoints in the input units.
When the loss of signal occurs both alarm channels are set as for an
alarm condition. The output state will depend on the coil energisation
setting for each channel.
AlarmInhibitInputs
When an alarm inhibit signal is applied the alarm channel is set as if
there was no alarm condition. The output state will depend on the coil
energisation setting for that channel.
Rateofchangealarms
Rate of change alarms are divided into three types: Rate of increase,
Rate of Decrease and Rate of change. A high rate of decrease will
trigger a high type alarm.
