The standard connection for the potentiometer is that on the left side of next
figure: potentiometer at rest on one end, in combination with a couple of travel-
demand switches. On request it is also possible to have the configuration on the
right side of next figure: potentiometer at rest in the middle, still in combination
with a couple of travel-demand switches.
The negative supply of the potentiometer is to be taken from one of NENC pins;
A21
(A15) and
Potentiometer resistance value should be in the 0.5 – 10 k range; generally, the
load should be in the 1.5 mA to 30 mA range.
A procedure for automatic acquisition of potentiometers signals can be carried
out using the console (see paragraphs 9.1, 9.2 and 9.3).
Analog inputs may also be used as extra digital inputs. In this case ADC value
should be used as the indicator of the input status. For example, a proximity
switch supplied from +B could be connected to an analog input.
Protection
Analog inputs are protected against short circuits to +B and -B. Each one has a
10 nF capacitor to -B for ESD protection.
Connector position
If an analog input is used as a speed reference to the motor controller, a
system safety strategy must be defined.
The application software must take care of analog input errors such as
VACC OUT OF RANGE or VACC NOT OK.
4.4.4 Encoder input
Inputs for motor-speed feedback (encoder signals) have an internal 1 kΩ pull-up
for open collector sensor output. Threshold levels are listed below.

Questions and answers
Como comprobar el funcionamiento del controlador dualac2 sin display
You can check the operation of the Zapi DUALACE2 NEW GENERATION controller without a display using the following methods:
1. Zapi Smart Console – Connect the Zapi Smart Console to the CAN bus to access diagnostics and parameter settings.
2. PC CAN Console – Use the PC CAN Console software to monitor and adjust controller settings.
3. Self-Diagnosis Feature – The controller performs self-diagnosis, and faults can be displayed using Zapi tools.
4. Alarm History Log – Check the log of alarms to review past faults and system behavior.
5. TESTER Function – Use the TESTER function to monitor key operational readouts.
These methods allow you to diagnose and verify the controller’s operation without an external display.

A brumby electrical truck that has a zapi inv.dace2, records the failure 244 "Warning Slave It depends on the supervisor uc", and the alarm 248 "Mc is Opened, eb is applied". On the other hand, the LED does not turn on, but in the manual I did not find the LED code. I would like more certainty about whether the failure is from the controller and the LED code for this Zapi model.
Failure 244 "Warning Slave" depends on the supervisor microcontroller (µC). No specific effect or troubleshooting steps are provided in the available context.
Alarm 248 "MC is Opened, EB is Applied" indicates that the main contactor (MC) is open, and the electric brake (EB) is applied. This typically occurs during start-up, standby, or other system states.
The LED code for this model is not explicitly provided in the available context.
