Alarms Fuse_Open, Ssr_Short; And Load_Open - gefran IR-12 Configuration And Programming Manual

ALARMS FUSE_OPEN, SSR_SHORT and LOAD_OPEN
Diagnostics is active to check correct functioning of the process:
- FUSE_OPEN alarm: trips at opening of internal fuse
- LOAD_OPEN alarm: trips when load is interrupted or disconnected
- SSR_SHORT alarm: trips when the solid status relay is in short circuit
NOTE1 : In PA_mode, the diagnostic Alarms Load-Open and Fuse_open are detected for SCR power firing higher than 40%.
NOTE2: In PA_mode, the diagnostic Alarm SSR-SHORT is detected when SCR power firing is P=0% or when its channel
is disabled.
The summary status of the alarms is shown in S.Alarm and the details for each output are shown in S.Out.Lp.o
(with p = phase from 1 to 3, o = output from 1 to 8).
