2) Vbatt is compared with a threshold value which comes as function of the
actual charge percentage; by this comparison the current provided by the
battery is obtained.
3) Current obtained at step 2 integrated over time returns the energy drawn
from the battery, in Ah.
4) Charge percentage is dynamically updated basing on the energy from step 3.
5) Threshold values for the battery charge can be modified by means of
BAT.MAX.ADJ. and BAT.MIN.ADJ. as to adapt the battery-charge detection
to the specific battery in use.
9.12 EVP Setup
When the EVP is set as ANALOG (see paragraph 8.2.2) the output is managed
as explained in the following example.
Considering the case in that the EVP request is concerning the lowering valve,
the MIN EVP parameter (see paragraph 8.2.2) determines the minimum current
set point applied to the valve when the position of the potentiometer is at the
minimum (MIN LOWER) (see paragraph 8.2.2).
Then, the current set point applied to the valve increases proportionally with the
potentiometer voltage up to the maximum (MAX EVP) (see paragraph 8.2.2),
reached when the position of the potentiometer is at the maximum (MAX
LOWER) (see paragraph 8.2.2).
If the valve is set as ON-OFF the MIN EVP parameter is disabled and the current
set point applied to the valve is only dependent by MAX EVP.
The dynamic delay seen during the modification of the current set point, in both
cases, ANALOG Valve and ON/OFF Valve, is dependent by the OPEN DELAY
and CLOSE DELAY parameters (see paragraph 8.2.2).
OPEN DELAY determines the current increase rate on EVP and it sets the time
needed to increase the current to the maximum permitted value.
CLOSE DELAY determines the current decrease rate on EVP and sets the time
needed to decrease the current from the maximum value to minimum.

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.
