## **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.

## **Terminal configuration** 

## **Installation** 

## **Install base unit without contact expander module:** 

- Ensure that the plug terminator is inserted at the side of the unit. 

## **Connect base unit and PNOZsigma contact expander module:** 

- Remove the plug terminator at the side of the base unit and at the contact expander module. 

- Connect the base unit and the contact expander module to the supplied connector before mounting the units to the DIN rail. 

## **Installation in control cabinet** 

- The safety relay should be installed in a control cabinet with a protection type of at least IP54. 

## **Dimensions**

- Use the notch on the rear of the unit to attach it to a DIN rail. 

- Ensure the unit is mounted securely on a vertical DIN rail (35 mm) by using a fixing element (e.g. retaining bracket or an end angle). 

- Push the unit upwards or downwards before lifting it from the DIN rail.
