The maximum speed detectable by standard Hardware configuration can be
limited depending on the number of pulse/rev. Contact Zapi technician for
checking
It is strongly suggested, for safety reasons, to lift the wheels from the floor
and set the correct value according to the type of sensor used prior to
perform any operation with the truck.
5.2.7 Connection of Motor temperature sensor
A temperature sensor with a positive temperature coefficient embedded in the
motor winding provides a means for the motor controller to monitor motor
temperature. Motor temperature is used in the vector control algorithms, and can
also be used to protect the motor from overheating.
The motor controller can be configured to operate with different sensors such as
KTY 84, PT1000 and similar.
Installation of the motor temperature sensor is done by the motor
manufacturer. Contact the motor manufacturer to get the correct wiring. If
the temperature sensor cables are not connected with the right polarity, the
sensor readings will not be correct and overtemperature protection of the
motor will not work properly.
5.2.8 Connection of main contactor and key switch
Main contactor and key switch can be connected as the following figure.
The connection of the battery line switches must be carried out following
instructions from Zapi.
If a mechanical battery line switch is installed, it is necessary that the key
supply to the inverter is open together with power battery line; if not, the
inverter may be damaged if the switch is opened during a regenerative
braking.
An intrinsic protection is present against battery voltages above 140% of the
nominal one and against the key switching off before disconnecting the
battery power line.

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.
