10 MAINTENANCE AND REPAIR

There is no periodic service requirement for the MFU.
Repairs should not be attempted on the module. The Network Interface Card and Interface Card are a
pair and should never be separated. Replacing the complete MFU assembly with a new replacement
device should rectify any failure. Static sensitive devices are used in the MFU, it is therefore
mandatory to observe anti-static precautions when handling or working on the unit.

10.1 Records

In order that a replacement can be easily introduced in the event of a device failure it is very important
to record and keep safe all the settings made for the variable registers. The table lists all the registers
that must be checked and set up for each Modbus Module on a network. The data should be recorded
for each module.
Note: Make a note of all changes to register settings to ensure that, in the case of a failure,
the replacement device can be swiftly set to the correct values.
