Thermostat and overheating cut-out
The thermostat is installed next to the heating
element and is used to reduce the element output
by turning it off if the ambient temperature
exceeds 135°C (±5°C) for condenser dryers and
110°C (±5°C) for others.
The machine is equipped with a overheating
cut-out, which is available in two versions, one
automatically resettable and one manual. The
overheating cut-out switches off the power supply
to all components if the temperature exceeds
150°C (±5°C) and closes the circuit once the
temperature drops below 135°C (±8°C). The
drying programme stops and must be restarted if
the overheating cut-out is triggered.
To reset the manual overheating
cut-out, the cover plate on the
machines back must be removed.
Press the button on the over-
heating cut-out for manual
reset.
The automatic overheating
cut-out resets when the
temperature drops below 135°C (±8°C) for
condenser dryer and 120°C (±5°C) for others.
Purpose: The thermostat measures
temperature and controls heating element
output. The overheating cut-out controls the
temperature and cuts the power supply if the
machine overheats.
EMC filter
The filter is installed next to the cable fasteners
where the connection cable enters the
machine. The filter consists of a number of coils,
condensers and resistors.
Purpose: To eliminate electromagnetic
interference to and from the machine.
Overflow guard
The overflow guard comprises a microswitch
triggered by a float. When the lower condensed
water container becomes full the float rises
and triggers the microswitch. The microswitch
isnormallyclosed;whenactivateditopens
the circuit. When the microswitch has been
open for more than 30 seconds, the drying
programme stops and the display shows “Over
flow”. You can erase this message by turning the
programme selector or pressing the Start/Stop
buttons.
Purpose: To provide protection from any
water leaks or flooding from the machine.
