7.2 THERMAL CUT OUT
Be aware of high
voltage in the block
area. The electrical
supply should be
switched off before
working in the heater
block compartment.
This operation is usually
carried out during
installation. If the
Smoke Screen has
been in service the
nozzles will be
extremely hot and
will cause injury if
touched. Therefore, the
Smoke Screen should
be switched off and
time should be allowed
for the nozzles to cool.
In the unlikely event that the temperature in the heater block increases significantly above the set working
temperature the TCO will trip to protect the machine from damage.
The TCO can be reset using the following
procedure:
●
Make sure the mains power to the machine is turned off before resetting the TCO.
●
Reset the TCO by pressing on the little button on the top area. If the thermal device has tripped it
should be possible to hear a click when it resets.
●
Switch on the mains power after resetting.
●
Check the machine heats up to normal operating temperature and make sure it archives a ready
state. See the operating “LCD, LED and Sound Indications” for further information on fault
indications.
NB: A TCO usually only trips if there is a problem. If it trips again the Smoke Screen should be checked
for faults before further use.
Note: The position of the
TCO
can be different depending on the machine version.
