18.9.4 “Pump controller” tab (transistor regulator - pump)
If the truck is equipped with a lift/lower transistor regulator, the Pump controller tab displays the following: • Status of digital inputs and outputs of the transistor regulator. pin refers to the motor controller pin designations as given in the circuit diagram. • Field PWM, Armature PWM, Field current, Armature current, Temperature - Measured values from the transistor regulator for the pump motor. See the explanation on page 11. • Raw throttle data - The received lift/lower signal as a percentage. • Out pin9 - The output signal to the proportional lowering valve as a percentage. • Inp pin 10 - The input voltage from the pressure sensor. “digital o” indicates the digital status of the input. • Inp pin 11 - The input voltage from the pressure sensor. “digital o” indicates the digital status of the input.
