1.6. Protection, safety and control elements

 Fixed guards: Covers. These protect the user from contact with dangerous points and material accidentally
ejected from the machine.
 Mobile guards: Filter cover.
 Breaker switch: These connect or disconnect the electrical power from the machine (on some models only
in accordance with Standard EN60204-1).
 Start safety: If a momentary interruption of the power supply occurs, the machine shuts down at once and
does not resume until the corresponding start button is pressed.
 Drum access door microswitch: If the door is opened during operation, the machine switches off the
heating and halts the drum rotation.
 Filter cover microswitch: If the filter cover is opened during operation, the machine switches off the heating

 Drum movement detector (Reed): This detects the rotation of the drum. If rotation halts unexpectedly, the
machine switches off the heating to avoid damaging the linen.
 Input thermostat: A passive safety system that limits the input temperature. This protects against
overheating caused by a fault in the system regulating the temperature.
 Output thermostat: A passive safety system that limits the output temperature. This protects against
overheating caused by a fault in the system regulating the temperature.
 Input temperature probe and output temperature probe: These constantly monitor the temperature at the
inlet and outlet, adapting it to the programmed value.
 Pressure-switch: Controls the vacuum in the exhaust circuit.
 Safety device to prevent back-flow of fumes. Oscillating shutter that prevents air from entering through
the extraction tube in the event of a back-flow situation.
