7.0 FUNCTIONING (see functional diagram)
The pressure switch controls the compressor. In the factory the pressure
switch is set to start and stop the machine at a specific pressure. When the
maximum pressure has been reached, the pressure switch works as follows:
∗ Types with thermal overload device: the compressor stops and relieves the
pressure from the internal air circuit. If pressure drops below the starting
pressure, the motor wilt start and the pump delivers air to the tank.
∗ Types with star-delta switch: the compressor stops and the internal air
circuit is being relieved from its pressure through the electric valve (14). If
pressure drops below the starting pressure, the following happens: the
electric valve is open and the compressed air is being released. A time
relay leaves the compressor to run freely for a few seconds in star position.
Then the compressor switches to delta position and the electric valve is
being excited and closes. Now the pump is working and pressure is being
built up in the tank until the maximum pressure is reached.
Valid for all Airpress compressors model K:
Sound power level: Lw(A) = 99 dB(A) (re 1 pW).
Sound pressure level: Lp(A) = 87 dB(A) (re 20 µPa).
