Introduction
This chapter provides the schedules and instructions, where applicable, for
routine inspection, cleaning and maintenance of the E5500 Mobile
Contribution Encoder (MCE) which should be performed by an operator.
There are also some basic fault-finding procedures to follow in the event of
a suspected MCE failure.

Preventive Maintenance
5.2.1
Routine Inspection
Cooling Fans
This equipment must never be operated unless all the cooling fans are
working. They should be checked whenever the MCE is switched on and
periodically thereafter.
NOTES...
1.
Failure to ensure a free flow of air around the unit may cause overheating. This condition is
detected by a temperature sensor on the Base Board 3ASI (Motherboard), which causes the
alarm relay to be energised.
2.
If the MCE is installed in a position in which the fans cannot be easily checked, check the Fans
parameter on the Status/System/General Menu (see Chapter 3, Operating the Equipment
Locally) to confirm the operation of the fans. This menu also contains a Temperature parameter
which shows the temperature inside the MCE chassis.
5.2.2
Cleaning
Unplug the MCE from the wall outlet before cleaning the exterior with a
damp cloth. Do not use liquid cleaners or aerosol cleaners.
NOTE…
Only the exterior of the case should be cleaned.
