E-STOP relays, safety gate monitors
**==> picture [72 x 42] intentionally omitted <==**
## **Up to PL c of EN ISO 13849-1** PNOZ s1
## **Function description**
- Single-channel operation: no redundancy in the input circuit, earth faults in the reset and input circuit are detected.
- Automatic start: Unit is active once the input circuit has been closed.
- Manual reset: Unit is active once the input circuit is closed and then the reset circuit is closed.
- Increase in the number of available instantaneous safety contacts by
- connecting contact expander modules or external contactors/relays; A connector can be used to connect 1 PNOZsigma contact expander module.

## **Wiring**
Please note:
- Information given in the “Technical details” must be followed.
- Outputs 13-14, 23-24 are safety contacts.
- To prevent contact welding, a fuse should be connected before the output contacts (see technical details).
- Calculation of the max. cable runs lmax in the input circuit:
- ������
- �����
- �������
Rlmax = max. overall cable resistance (see technical details) Rl /km = cable resistance/km
- Use copper wire that can withstand 60/75 °C.
- Sufficient fuse protection must be provided on all output contacts with capacitive and inductive loads.
