9.11 Battery-charge detection
During operating condition, the battery-charge detection makes use of two
parameters that specify the full-charge voltage (100%) and the discharged-
battery voltage (10%): BAT.MAX.ADJ and BAT.MIN.ADJ.
It is possible to adapt the battery-charge detection to your specific battery by
changing the above two settings (e.g. if the battery-discharge detection occurs
when the battery is not totally discharged, it is necessary to reduce
BAT.MIN.ADJ).
Moreover, BDI ADJ STARTUP adjusts the level of the battery charge table at the
start-up, in order to evaluate the battery charge at key-on. The minimum variation
of the battery charge that can be detected depends on the BDI RESET
parameter.
The battery-charge detection works as the following procedure.
Start-up
1) The battery voltage is read from key input when the battery current is
2) Vbatt is compared with a threshold value which comes as function of the
3) The threshold value can be changed with the BDI ADJ STARTUP
4) If the new charge percentage is within the range "last percentage (last
Operating condition
Measure of the battery voltage, together with the charge percentage at the time of
the voltage sampling, give information about the instantaneous battery current.
1) The battery voltage is read when the battery current is not zero, which is
when the output power stage is driven. Vbatt is evaluated as the average
value over a window of time.

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.
