3.2.2 Regular
maintenance
work
The following work must be performed in connection with regular maintenance:
Switch the key switch on the controller to the position “Test Mode”
all LED
displays on the front panel of the device will light up for a few seconds (LED
test). Switch the key switch on the controller back to the position “0”.
Connect the controller to the service PC and perform a “Quick Start” with the
FibroManager. Check all channels and observe the status messages on the
individual channels. Remove possible faults on the sensor cables or fibre-optical
connectors. Compare the fibre lengths with the values taken during the previous
maintenance and if necessary, clarify possible causes of changes.
Read out the event memory of the controller with the FibroManager and analyse
it with the help of the filter options, e.g. in regard to errors, warnings and other
events.
Generate and evaluate the temperature profile and backscatter curves.
Perform test triggering, verification of the data transfer and alarm forwarding as
well as additional application-related tests that are described in the operation
manual of the controller and intended in accordance with national regulations.
Please refer to the operation manual for all information on controller maintenance
such as how to record data, generate the temperature profile and backscatter
curve, carry out test operations on the controller and the support functions such as
how to reading out the event memory or generating reports.
