This function displays as Alarm-□ Status and it is connected Relay or TR Type’s output card
information. One card for relay has 4 outputs(Alarm-1 Status to Alarm-4 Status), for TR has 6
outputs (Alarm-1 Status to Alarm 6 Status).
Relay output card(KRN-AR4) is connectable up to 3, and TR output card (KRN-AT6) is
connectable up to 2 at Slot7 to 10.
Alarm output turns ON or OFF by total 4 alarm conditions and relay, TR output are able to output
by max. 48 alarm conditions. However, every relay output and TR output condition is OR
operation (Among several alarm conditions connected one alarm output, even one alarm
condition is met, output must turn ON.).
 Set range: N.O. ↔ N.C.
 Factory default: N.O.
REALY and TR type output is basically fixed as Normally Opened method and H/W when power
is ON.
Therefore, KRN100 takes booting time max. 20sec and maintains Normally open status. In case
of RUN mode after booting, it maintains use-defined output type; Normally Open or Normally
Closed.
