14.15. Sensor of threefold pressure
The sensor of threefold pressure represents the combined switch of low pressure (to check quantity of a coolant), average pressure (for turning on of the fan of the condenser) and a high pressure (for overheat prevention).
The sensor is established in the receiver and when pressure becomes approximately equal 200 kPas or less, the condenser fan, thus, excepting a compressor overheat is switched off. When pressure reaches 3214 kPas, the compressor is switched off.
