8.6 Level sensor
All units are equipped with a level sensor. The level sensor is mounted in the tank where it is responsible for signalling low
water level conditions. If this problem is detected the sensor sends an alarm signal to the control unit resulting in an
immediate shutdown of the chiller.
Adopt all the possible precautions in order to prevent accidental contact with electrically live parts.
The voltage present in the electrical cabinet can reach values that are potentially fatal for humans.
The level sensor has been calibrated to function with 250kOhm sensitivity (position A=5, B=H on the “Empty” side).
Calibration of the level sensor is performed by the manufacturer so it must not be altered.
There is an anti-tamper sticker over the adjustment potentiometers (A and B).
Damaging this sticker, even partially, will automatically invalidate the warranty.
The Amber LED switches
on in the presence of
water (in normal
operating mode) and
switches off in the
absence of water.
Power on the system; the
green LED will switch
steady on.
