Travel demand switches.
The Procedure for automatic potentiometer signal acquisition is carried out using the
Hand Set. This enables adjustment of the minimum and maximum useful signal
level, in either direction.
3.3 Other analogue control unit
If the Zapi can tiller is not used, input CNC#9 can be used as analogue input, whose
typical application is a proportional command to enable a lifting/lowering function. It
is possible to use this input for an alternative function like a proportional braking.
It should be in a 3 wire configuration. Potentiometer value should be in the 0.5-10
kOhm range. Generally, the load should be in the 1.5mA to 30 mA range.
The CPOTL (CNA#9) signal range is from 0 to 10V.
Use CNC#8 (positive) and CNA#3 (negative) to supply it.
3.4 Analog motor thermal sensor input
Input CND#3 is an analogue input to receive an analogue thermal sensor signal to
measure the Traction Motor Winding Temperature. The analogue device installed in
the motor has to be specified, in order to insert the correct look-up table in the
software. A digital device can also be used.
