11.14 Refrigerant pressure switches LPS – HPS – PV
To ensure the operational reliability and the protection of the chiller, a series of pressure switches are installed in the
gas cycle.
LPS :
Low-pressure guard on the suction side of the compressor, which is triggered when the pressure drops below
the predetermined value. The values are reset automatically as soon as the nominal conditions are re-
established.
HPS :
The high-pressure control unit on the discharge side of the compressor is activated when the pressure
exceeds the predetermined value. It has a manual reset button on the control itself.
PV :
Fan control pressure switch which is installed on the discharge side of the compressor. It keeps the
condensation temperature and pressure constantly in the range of the preadjusted limit values (air-cooled)

To ensure the operational safety and the soundness of the chiller, a safety
temperature switch (TS) is installed at the refrigeration cycle. In the event that the
pressure gas temperature is too high, the sensor of the temperature switch will
stop the refrigerating compressor to prevent the pressure gas temperature getting
too high.
The temperature switch is reset manually, but only when the normal operating
conditions are reached again. Unscrew the cover (see pos. 1 in the illustration)
and press the reset button (see position 2 in the illustration).
