Important for detection of shorts across contacts:
As this function for detecting shorts across contacts is not failsafe, it is tested by Pilz during
the final control check. If there is a danger of exceeding the cable runs, we recommend the
following test after the installation of the device:
1. Unit ready for operation (output contacts closed)
2. Short circuit the test terminals S12, S22 for detecting shorts across the inputs.
3. The unit's fuse must be triggered and the output contacts must open. Cable lengths in
the scale of the maximum length can delay the fuse triggering for up to 2 minutes.
4. Reset the fuse: remove the short circuit and switch off the supply voltage for approx. 1
minute.
