To operate:
①Supply voltage:
- Apply voltage to A1 and A2.
- AC only: Connect the operating earth
terminal with the ground earth.
②Reset circuit:
- Automatic reset: Link S33-S34 and
Y36-Y37.
- Manual reset with monitoring: Connect
button to S33-S34 (Y36-Y37 open).
- Manual reset without monitoring:
Connect button to S33-S34, Y36-Y37
linked.
③Input circuit:
- Single-channel: Link S12-S52 and S21-
S22. Connect N/C contact from safety
switch (e.g. emergency stop) to S12
and S11.
- Dual-channel, without short circuit
detection: Link S21-S22. Connect N/C
contact from safety switch (e.g.
emergency stop) to S11-S12 and S11-
S52
- Dual-channel, with short circuit
detection: Link S11-S52. Connect N/C
contact from safety switch to S11-S12
and S21-S22
④Feedback control loop: Link Y1-Y2 or
connect external relays/contactors in
series
If the operating voltage is applied and all
conditions met, the safety contacts are
closed and the auxiliary contact (41-42) is
open. The status indicators "CH.1"and
"CH.2" are illuminated. The unit is ready for
operation.
If the input circuit is opened, the safety
contacts 13-14, 23-24, 33-34 open and the
auxiliary contact 41-42 closes. The status
indicators go out.
