2.3 Basic function principles
Pulse sequence monitoring (cycle)
1. Monitoring is enabled with a falling edge at Input 1 .
2. If the pulse sequence is too slow (cycle time t
P
too long), the output relays switch off for a minimum
switch-off time t
Amin
. The minimum switch-off time can be specified in register R36 [ } 29] .
3. If a pulse sequence (1 cycle) was recognized as correct, the output relays will only switch on again
once monitoring is enabled again. This switching mode ensures that triggering of the watchdog re-
mains recognizable.
4. The two output contacts are looped into the control circuit of the switch-off relay.
Automatic self-start is prevented, since the switch-off function block has to be reset through an explicit
manual intervention (monitoring enable).
