GF83.40-P-2115-01GI Auxiliary Fan, Function
- with CODE (580a) Automatic air conditioning

Function
Depending on the refrigerant pressure and/or the coolant temperature the left auxiliary fan (M4m1) and the right auxiliary fan (M4m2) are actuated.

The all-activity module (AAM) (N10) receives the coolant temperature by the coolant temperature sensor(B11/4) and the refrigerant pressure by the refrigerant pressure and temperature sensor (B12/2). The all-activity module (AAM) (N10) compares this input information with stored values and actuates the left auxiliary fan (M4m1) and the right auxiliary fan (M4m2).

When the following values are indicated the left auxiliary fan (M4m1), right auxiliary fan (M4m2) are switched on or off:
- refrigerant pressure > 16 bar = auxiliary fan ON
- refrigerant pressure < 13 bar = auxiliary fan OFF
- coolant temperature > 105 degrees C = auxiliary fan ON
- coolant temperature < 97 degrees C = auxiliary fan OFF
