9 OTHER FUNCTIONS
9.1 Program VACC function
This function enables the adjustment of the minimum and maximum useful levels
of the voltage from the accelerator potentiometer, in both directions. This function
is particularly useful when it is necessary to compensate for asymmetry of
mechanical elements associated with the potentiometer, especially relating to the
minimum level.
The following two graphs show the output voltage of a potentiometer versus the
mechanical angle of the control lever. Angles MI and MA indicate the points
where the direction switches close, while 0 represents the mechanical zero of the
lever, i.e. its rest position. Also, the relationship between motor voltage (Vmot)
and potentiometer voltage (Vacc) is shown. Before calibration, Vmot percentage
is mapped over the default 0 – 5 V range; instead, after the adjustment procedure
it results mapped over the useful voltage ranges of the potentiometer, for both
directions.
Before 'PROGRAM VACC'.
PROGRAM VACC can be carried out through Zapi PC CAN Console or through
Zapi Smart Console. For the step-by-step procedures of the two cases, refer to
paragraphs 13.1.4 or 13.2.6.
9.2 Program LIFT / LOWER function
This function allows to adjust the minimum and maximum useful signal levels of
lift and lowering request. This function is useful when it is necessary to
compensate for asymmetry of the mechanical elements associated with the
potentiometer, especially relating to the minimum level.
This function looks for and records the minimum and maximum potentiometer
wiper voltage over the full mechanical range of the lever.
The values to be acquired are organized in the ADJUSTMENT list, they are:

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.
