AFNZPxxx – DUALACE2 NEW GENERATION – User Manual
Description
This parameter enables or disables the NEB output
(A18), dedicated to the electromechanical brake.
NONE = Diagnoses are masked and E.B. is not driven
upon a traction request.
BRAKE = E.B. is driven upon a traction request if all
the related diagnoses pass. The behavior on a slope
depends on the STOP ON RAMP setting.
Do not use this setting if the electromechanical
brake is not really present.
Note: in applications with two controllers driving two
traction motors and only one E.B., this parameter has to be
set on BRAKE only in the controller that drives the E.B.
This parameter defines the voltage compensation for the
MC and EB drivers in dependence of the battery voltage.
0 = None.
1 = MC only.
2 = EB only.
3 = MC and EB.
This parameter enables or disables the bumper stop
function.
OFF = function disabled
ON = function enabled according to dedicated inputs
state
It enables or disables the syncro message
OFF = the syncro message is not used
ON = the syncro message is enabled
It enables or disables the autonomous management of the
Brake output:
OFF = the output is activated or deactivated according
to the signal received by CAN bus
ON = the output is managed autonomously by the
controller itself ignoring any activation/deactivation
signal received by CAN bus
This parameter enables or disables the acceleration-
modulation function.
OFF = The acceleration rate is inversely proportional to
the ACCEL DELAY parameter.
ON = The acceleration ramp is inversely proportional to
the ACCEL DELAY parameter only if speed setpoint is
greater than 100 Hz. Below 100 Hz the acceleration
ramp is also proportional to the speed setpoint, so that
the acceleration duration results equal to ACCEL
DELAY.
See paragraph 9.5.

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.
