All LEDs at once,

case of a
protection alarm.
*The External Acknowledgment might be disabled if parameter » Ex Ack «is set to »inactive« within menu [Device
Para / Acknowledge]. This blocks also the acknowledgment via Communication (e.g. Modbus).
** If the automatic acknowledgment is active all LEDs get acknowledged with a protection alarm.
The automatic acknowledgment must be activated by setting:
[Device Para / LEDs / LEDs group A / LED 1...n]
»Latched« = “active, ack. by alarm”
