•
Auto-start: Check if the reset circuit is connected to terminal S21
with U
B
. Check the synchronisation time between I1 and I2. If I1 is
present before I2, then the maximum time between the two signals
should not exceed 300 ms
•
Monitored manual start: Check the wiring of the reset circuit. Does
the reset button work properly?
Note: The falling edge of the start signal is evaluated (contact
opens)
•
Check if the feedback circuit through some connected contactors
or expansion modules work properly. If not, replace the faulty
device and perform a reset
