D.2. Undervoltage (supply, failure #2)
Supply voltage: 24 V DC - 20%/+25%
A built-in voltage monitoring reacts in two steps to falling be-
low certain limiting values:
1st Step
Cause
Supply voltage approx. < 19 V
Reaction
interrupt module no. 17 is activated
the program run is not yet interrupted
Buffered operands (markers, timers and counters) can be reset
unvolutarily if the user program is processed further in this
phase. The cause for this would be that, because of the
undervoltage, inputs could perhaps recognize a 0 signal al-
ready.
Indication
"failure" LED flashes
Error byte "ERR00.00" is set to 2
