Protection from rain
The rain protection prevents rain from entering the machine. At the same time it protects the display of the
Elektronikon regulator against sun and rain.
High ambient temperature (HAT)
The compressor is specially designed for continuous operation under humid and high ambient temperature
conditions. The maximum ambient temperature is 50˚C (122˚F).
Phase Sequence Relay
The phase sequence relay prevents the drive motor from rotating in the wrong direction.
PT 1000/100 Thermal motor protection
Not available for GA 110, GA 250, GA315 , GA 355, GA 500, GR 160 and GR 200.
The PT1000/100 thermal protection provides protection for the drive motor. Five sensors are installed in the
motor, two to measure the temperature of the bearings and three to measure the temperature of the windings.
The readings can be called up on the display of the Elektronikon regulator. A message will appear on the
display and the general alarm LED will light up if one of the temperatures exceeds the shut-down warning
setting.
