GFK-2734
10.1
Maintenance
The device is designed in such a way that maintenance work is not required during the
duration of use. However, depending on the application and connected I/O devices it may
be necessary to test the function of the I/O devices and the safety chain at regular intervals.
The duration of use of the module is 20 years.
Observe the cycles of the relays (see "Safe digital relay outputs" on page 11-4).
Switch the safety relays at regular intervals (for proof test interval see "Safe digital relay
outputs" on page 11-4).
Carry out maintenance of connected I/O devices (e.g., light grid) according to the relevant
manufacturer specifications.
10.2
Repair
Repair work may not be carried out on the safety module. In the event of an error, send the
module to GE Intelligent Platforms.
It is strictly prohibited to open the safety module. In order to prevent the manipulation of the
module and to detect the unauthorized opening of the module, a security seal is applied to
the module. This security seal is damaged in the event of unauthorized opening. In this
case, the correct operation of the safety module can no longer be ensured.
10.3
Decommissioning and disposal
The machine or system manufacturer specifies the procedure for decommissioning.
Decommissioning may only take place according to these specified procedures.
