WARNING
Servicing and repairing your controller
Always isolate your controller at source before you open the unit
to inspect it or replace fuses.
When it comes to machine maintenance there is very little that you
need to do to look after it.
Replacement parts
We do not expect that you will need to repair any controller parts
at board level, other than fuses. In the unlikely event of any board
failure then we provide an excellent repair and exchange facility
for all our customers.
Cleaning and Inspection
Any excess dust that has entered into the cabinet may be
removed with a light brush and vacuum cleaner.
Any internal cable forms, that flex to accommodate opening doors,
should be checked to see that there is no fraying, or damage, to
cable insulation.
External cables should be checked to see that there has no
damage to the flexible conduit, plugs or sockets. If the flex has
been squashed, if there is visible damage, or if there are any
exposed conductors, then, for your own safety, it must be
replaced.
If the equipment is subject to vibration then we recommend that
you use an insulated screwdriver to check that no terminals have
become loose.
Troubleshooting
The control system has several features, which provide an early
diagnosis of faults in the control system, the tool heaters and
thermocouple sensors.
Individual Card Diagnostics
If a fault on a controller card is suspected, check the LED card
status lamps on the controller card.
From left to right they are:

ground. Message “Gnd” shows in faulty zone.
LED is lit when the thermocouple is open or flashing
reversed. Message “- - -” shows in faulty zone.
