• ALARM HYSTERESIS (DEADBAND)
Hysteresis, a deadband between ON point and OFF point, is used to prevent frequent ON/OFF operations (generally called
‘chattering’) of an alarm output device when the current fluctuates around the setpoint.

• ALARM LATCHING
Once an alarm is tripped, it is held when the alarm condition is cancelled.
Latched alarm is reset by turning the device’s power supply off or by a Modbus command.

• ALARM OUTPUT
Specify the output device for alarms.
When one of the control outputs is specified, be sure also to specify ‘Alarm OR’ or ‘Alarm AND’ with its output assignment.
With ‘Alarm OR’ setting, the output is provided if one or more alarms assigned to it are in true conditions. With ‘Alarm AND’
setting it is provided only if all alarms assigned to it are in true conditions.
