At start-up, the hardware circuit dedicated to enable and disable the EB driver
(output NEB, pin A28) is found to be faulty. The hexadecimal value "XX"
facilitates Zapi technicians debugging the problem.
Troubleshooting:
This type of fault is not related to external components. Replace the logic board.
HW FAULT EV. XX (MDI/LED code = 16)
Cause:
At start-up, the hardware circuit dedicated to enable and disable the EV drivers is
found to be faulty. The hexadecimal value "XX" facilitates Zapi technicians
debugging the problem.
Troubleshooting:
This type of fault is not related to external components. Replace the logic board.
HW FAULT XX (MDI/LED code = 32)
Cause
At start-up, some hardware circuit intended to enable and disable the power
bridge or the LC driver (output NLC, pin A26) is found to be faulty. The
hexadecimal value "XX" facilitates Zapi technicians debugging the problem.
Troubleshooting
This type of fault is related to internal components. Replace the logic board.
INCORRECT START (MDI/LED code = 79)
Cause:
Incorrect starting sequence. Possible reasons for this alarm are:
- A travel demand active at key-on.
- Man-presence sensor active at key on.
Troubleshooting:
Check the states of the input at key-on.
Check wirings and the microswitches for failures.
Through the TESTER function, check the states of the inputs are coherent with
microswitches states.
If the problem is not solved, replace the logic board.
INIT VMN HIGH XX (MDI/LED code = 31)
Cause
Before closing the LC, the software checks the power bridge voltage without
driving it. The software expects the voltage to be in a "steady state" value.
If it is too high, this alarm occurs. The hexadecimal value "XX" identifies the faulty
phase:
81: phase U
82: phase V
83: phase W
Troubleshooting
Check the motor power cables.
Check the impedance between U, V and W terminals and -B terminal of the
controller.
Check the motor leakage to truck frame.
If the motor connections are OK and there are no external low impedance paths,
the problem is inside the controller. Replace it.

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.
