9.4 Potentiometers
The controller can handle different types of potentiometers and, if present,
direction and enable switches. Parameters MAIN POT. TYPE and AUX POT.
TYPE are to be set accordingly to the configuration of the machine (see
paragraph 8.2.4).
The following graphs describe how the mechanical position of the potentiometer
wiper and its voltage result in the forward and backward requests. Basing on the
application, the voltage excursion may differ from the 0 V through 5 V here
shown.
Adopting a Z-type potentiometer, both the speed set-point and the travel direction
are defined; direction switches are not mandatory.
Adopting a V-type potentiometer, only the speed set-point is defined; a couple of
direction switches are mandatory, except where the application only requires one
direction of rotation (for example only lift in pump applications).

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.
