Maintenance and Repair

Maintaining, Repairing or Replacing the Device

In case of maintenance, repair or replacement of the device, proceed as follows:

1.

Implement appropriate maintenance procedures for regular maintenance of the safety loop.

2.

While the device is maintained, repaired or replaced, the safety function does not work.

Take appropriate measures to protect personnel and equipment while the safety function 

is not available.

Secure the application against accidental restart.

3.

Do not repair a defective device. A defective device must only be repaired by the manufacturer.

4.

If there is a defect, always replace the device with an original device.

Danger!

Danger to life from missing safety function
Changes to the device or a defect of the device can lead to device malfunction. 

The function of the device and the safety function is no longer guaranteed.
Do not repair, modify, or manipulate the device.
