Note that:
● Both limits can be evaluated separately in the control system only for settings 1 or 4 since
● The response of both limits cannot be detected in the "READBACK" and "POS_D" status
● The direction of action shown reverses for an alarm unit.
● The direction of action also reverses when the setting of the response threshold of alarms
● The hysteresis of the limit is 1% by default.
● In the factory setting "OFF", the output of both alarms "41.A1" and "42.A2" is deactivated.
The factory setting is "OFF".
