7.4 Potentiometer in the Brush Head Lifting Unit
The potentiometer of the lifting element is powered by a 2.5 V reference voltage at
A1.X19:1. Reference point for this voltage is A1.X19:3. Depending on the position of
the potentiometer, the voltage at A1.X19:2 is between 0 and 2.5V.
Measuring point :
A1.X19:1 – A1.X19:3
2.5V Reference Voltage
A1.X19:2 – A1.X19:3
0..2.5V 0...2.5V depending on the position of the lifting
element
element
Possible faults :
A1.X19:1- A1.X19:3
less than 2.5V or 0V
Short circuit in the wiring or in the potentiometer. 0V indicates a a short circuit to
ground. Voltage less than 2.5V indicates an overload of output A1.X19:1.
