7.8 Service and Repair The Controller
WARNING -
HIGH VOLTAGE
Always isolate the controller at source before you open the unit to inspect it
or replace fuses.
CAUTION
External cables should be checked to see that there has been no damage
to the flexible conduit, plugs or sockets. If the flexible conduit has been
damaged or if there are any exposed conductors, it must be replaced.
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.
CAUTION
CAUTION
Only use ceramic body fuses on control cards. Never use glass-bodied
fuses.
CAUTION
7.8.1 Replacement Parts
Mold-Masters
does 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.
7.8.2 Cleaning and Inspection
Any excess dust that has entered into the cabinet may be removed with a
light brush and vacuum cleaner.
If the equipment is subject to vibration, then we recommend that you use an
insulated screwdriver to check that no terminals have become loose.
7.9 Upgrade the Software
In order to maintain our high quality, our development engineers are making
continual improvements to our control system.
It may be possible to apply system upgrades to your own controller
depending on the type and age of your equipment. Please contact your
supplier and provide the serial number for your model to find out if your
particular console can be upgraded.
There is usually no need to return your control system to your supplier for any
upgrades. They may be downloaded via the internet.
7.9.1 Preparation
1. Download the upgrade from the internet onto a personal computer.
2. Copy the upgrade program / data onto memory stick.
IMPORTANT
Before you start any upgrade, shut down the machine to leave the console
free.
