Overcurrent protection is applied by hardware.
EB outputs can be only a PWM voltage-controlled output. It cannot be used as
current-controlled output.
Driving an inductive load on a PWM-modulated open-drain output, there is
always to be a path for the current through the freewheeling diode. Do not
connect any switch or fuse in series with the diode.
Connector position
To protect the motor controller from overvoltage at inductive load, internal
freewheeling diode toward pin
Please ensure that the inductive load is connected such that the path for
the freewheeling diode is always intact, or use an external freewheeling
diode if this is not possible.
Use of brushless fans or other loads with built-in capacitor can give high
inrush current at turn on, which can give an open-drain over-current trip.
The inrush current must be below the open-drain peak current.
4.4.7 PWM current-controlled output
In premium version only (35-poles Ampseal) an additional Open-drain current
controlled output can be used for operating services such as relays, hydraulic
valves, horn, etc.
In order to utilize the built-in freewheeling diodes, the loads must be supplied
from pin PIN A24, see paragraph 3.1.1.
In case the vehicle design does not allow the usage of the built-in freewheeling
diodes, i.e. if the return path integrity cannot be guaranteed in all situations,

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.
