To protect the motor controller from overvoltage at inductive load, internal
freewheeling diodes are mounted to the
Please ensure that inductive loads are 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 fan or other loads with built-in capacitor can give high
inrush current when turn ON which will give an Open Drain over current
trip. The inrush current must be below the open-drain peak current.
4.4.8 High-side driver
In premium version only (35-poles Ampseal), a high-side switch provides
redundancy in turning off the EB and the EVs. If one of the open-drain outputs is
short circuited, it is possible to turn off the high-side switch so to disconnect the
load on pin
The high-side switch has a maximum output current of 5 A. The high-side switch
can only be controlled as an on/off switch, it is not suited for switching operation.
The high-side switch has a maximum output current of 4 A.
The high-side switch can only be controlled as an on/off switch, it is not suited for
switching operation.

4.4.9 Motor-temperature measurement
Inputs for motor-temperature sensors, for measuring the temperature of each
motor windings, is available on pin PTH_R
Compatible temperature sensors are like:
- KTY84 with 1000Ω @ 100°C.
- KTY83 with 1670Ω @ 100°C.
- PT1000 with 1385Ω @ 100°C.
- On/Off.

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.
