8. Set-up and maintenance

8.1 Commissioning

The safety relay module features protection class IP54 for installation

in a switch cabinet.

The safety relay module is delivered ready for operation.

Application 1 is preset in the factory.

8.2 Functional testing

The safety function of the safety-monitoring module must be tested.

The following conditions must be previously checked and met:

1. Correct fixing

2. Check the integrity of the cable entry and connections

3. Check the safety-monitoring module's enclosure for damage

4. Check the electrical function of the connected sensor technology

and their influence on the safety-monitoring module and the

downstream actuators

The safety relay module features self-test functions.

If a fault is detected, the system adopts a safe mode and leads,

if necessary, to undelayed deactivation of all safety outputs.

8.3 Behaviour in the case of faults

In the event of a fault the following procedure is recommended:

1. Identify faults according to flash codes from chapter 6.2.

2. Rectify the fault if it is described in the table.

3. Switch operating voltage off and on and erase fault mode.

If fault could not be rectified, please contact the manufacturer.
