6 Maintenance and Repair
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.
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.
Reporting Device Failure
If you use the device in a safety loop according to IEC/EN 61508, it is required to inform
the device manufacturer about possible systematic failures.
Report all failures in the safety function that are due to functional limitations or a loss of device
function – especially in the case of possible dangerous failures.
In these cases, contact your local sales partner or the Pepperl+Fuchs technical sales support
(service line).
It is not necessary to report failures in the safety function that are due to external influences
or damage.
