Two-hand relays 

## **Up to PL e of EN ISO 13849-1** PNOZ s6.1 

Two-hand control device for safety circuits 

## **Approvals** 

## **PNOZ s6.1** 

## **Unit features** 

- Positive-guided relay outputs: 

- 3 safety contacts (N/O), instantaneous 

- 1 auxiliary contact (N/C), instantaneous 

- 1 semiconductor output Connection options for: 

– 2 operator elements (buttons) A connector can be used to connect 1 PNOZsigma contact expander module LED indicator for: 

- Supply voltage 

- Input status, channel 1 

- Input status, channel 2 

- Switch status, safety contacts 

- Feedback loop 

- Fault 

Plug-in connection terminals (either spring-loaded terminal or screw terminal) See order reference for unit types 

## **Unit description** 

The two-hand control relay meets the requirements of EN 574 Type IIIA. It 

forces the operator to keep his hands outside the danger zone area during the hazardous movement. It is designed for use in two-hand circuits. **CAUTION!** 

The two-hand control relay may **not** be used on **press controllers** . It is only suitable for use where the risk analysis has established a low level of risk (e.g. EN 954-1 Cat. 1). 

## **Safety features** 

The two-hand control relay meets the following safety requirements: 

The two-hand control relay prevents the plant from being enabled in the following cases: 

- Power supply failure 

- Component failure 

- Short circuit on an input circuit 

- Coil defect 

- Open circuit 

- Earth fault 

In each on-off cycle, the output relays on the safety device are tested to ensure they open and close correctly

Two-hand relays 

**==> picture [72 x 42] intentionally omitted <==**

## **Up to PL e of EN ISO 13849-1** PNOZ s6.1 

## **Function description** 

- The two-hand control relay must be activated by simultaneously press- 

ing two buttons within **0.5 s** . If one or both of the buttons are released, the unit interrupts the control command for the hazardous movement. 

- Reactivation: The output relays will not re-energise until both operator elements have been released and then re-operated simultaneously.

## **Wiring** 

Please note: 

- Information given in the “Technical details” must be followed. 

- Outputs 13-14, 23-24, 33-34 are safety contacts, output 41-42 is an auxiliary contact (e.g. for display). 

- 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.

## **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**

- 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.
