Section 8 - Troubleshooting
WARNING
Ensure that you have fully read "Section 3 - Safety" before troubleshooting
any issues with the controller.
CAUTION
The fuse detection circuit requires a continuous low level current through a
high impedance bleed resistor to maintain the alarm condition.
As a result the load circuit is still connected to the mains voltage supply and
it is not safe to attempt to repair or replace the fuse without first isolating the
circuit.
8.1 Introduction
The control system has several features that provide an early diagnosis of
faults in the control system, the tool heaters and thermocouple sensors:
If the system detects any abnormal condition, it displays a warning message
on the Main page.
If a zone temperature is seen to deviate from the actual setting beyond the
alarm limits then the display will change to white text in red box and generate
a remote alarm.
If the system detects a malfunction in one or more of the control zones, then
it displays an error message on the Main page in place of a temperature
value.
See "Table 8-1 Fault and Warning Messages" for more details.
