figure (potentiometer on one end at rest) in combination with a couple of Travel
demand switches . On request it is also possible the handling in the Right side of
next figure (potentiometer in the middle at rest) still in combination with a couple
of 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 CNA#30 can be used as analogue input
(the “PEDAL WIRE KO” warning is lost), 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-
10Kohm range. Generally, the load should be in the 1.5mA to 30 mA range.
The CPOTL (CNA#30) signal range is from 0 to 10V.
Use CNA#25 (positive) and CNA#5 (negative) to supply it.
3.4 Analogue motor thermal sensor input
Input CNA#22 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.
