4.3.5 Operating problems
WD-59CTS & WD-66CTS
Troubleshooting
If the touch panel screen gives no indication of whether the ON/OFF button has
been pressed, check the main switch to see whether it is turned on. If the problem
persists, contact authorised service personnel.
The figure on the touch panel will change when an error or an alarm is presented.
There are three different levels.
1.
Information alarms (blue), which can be dealt with by the operator
2.
Error alarms (yellow), which can often be dealt with by the operator
3.
Critical error alarms (red), where service personnel must be contacted
The majority of these alarms can be remedied by the operator. Some blue alarms
that have been dealt with by the operator a number of times will eventually change
to yellow or red alarms, meaning that service personnel must be contacted.
Depending on previous settings, the machine may be stopped but not restarted
until the cause of the alarm has been addressed. The operator is assisted by
guides presented on the touch panel to perform measures or alternatively contact
details for a service provider will be displayed.
