Message

43 Emergency Signal If GNR (Input1) is Up & EGGNR (input2) is Up then it is OM S1 Emergency
Cancellation Emergency Signal Cancellation. GNR, EGGNR are triggering. Signal Cancellation

In Between WNR (input1) Up to Up, if NWKR (input2),

RWKR (input3) are not Up then it is Point Repeated 13 NWKR Point
44 Point Repeated Operation Operation. WNR is triggering (or) In between NCR/RCR OM Repeated
up to Down if Point (NWKR/RWKR) is not set then it is Operation
Point repeated operation, NCR/RCR (Down) triggering.

45 Panel Failure due to AC All RECR's (Conflicting signals) are down then it is Panel Panel Failure Due
Power Failure failure due to AC Power Failure. All are triggering inputs. MM to AC Power
Failure

46 Panel Failure due to DC All ASR's (Conflicting signals) are down then it is Panel Panel Failure Due
failure due to DC Power Failure. All are triggering MM to DC Power
Power Failure
inputs. Failure
When RECR (input1) is Up and TPR1 (input2), TPR2
(input3) are Down, TPR3 (input4) is Up and time
difference between TPR2 Down (triggering) and TPR3
S1 Shunting with
47 Shunting with Permission Up is more than time T1, and the time difference MM
Permission
between TPR2 Down and RECR Up is more than the
given time interval T1, TPR2 is continuously Down for
T2., SHKR Down status considered in extra variable.
