An alarm can be acknowledged only if its source is already deactivated.
The Master MAIN, as well as Extended system, has following binary outputs:
•
3x fast (≤ 2 ms) TRIP 1 / 2 / 3 outputs
•
1x TRIP ALARM output
•
1x WATCHDOG (WD) output
Fast TRIP outputs
All TRIP 1, TRIP 2 and TRIP 3 outputs (NO) are activated immediately after a trip event
“T.13” has been detected. The system response time, measured from real Arc fault
occurs to the activated TRIP outputs, is less than 2 ms.
TRIP ALARM output
The TRIP ALARM output (NO) is also activated immediately after a trip event “T.13” has
been detected.
WATCHDOG output
The WD output is working as normally closed contact (NC) and will become active (open
contact) if an system error alarm “E.xx” (xx = event number) is detected or the power
supply is off (please see chapter 3.11 Events & Alarms).
