Instruction Manual
In the event of problems due to the start-up sequence, 2 items can be of importance:
Ü
After power failure, KS 98 /98-1 continues running during fractions of seconds and may still detect already
de-activated process signals.
*
If the behaviour after power recovery is different depending on whether the function blocks are still in the pre
-
vious condition or whether they were initialized, the following engineering can provide the initialization infor
-
mation within the first 1.6 seconds after starting up.
Another possibility for power failure detection is to set an internal flag in the status block via digital input “pwrchk” at
the end of the initialization phase. This Flag is available at digital output ”pwrchk". After power failure, this flag and
thus digital output “pwrchk” is always initialized with 0.
