Protection
PTH input is protected against short circuits to +B and ESD protected by
suppressor device. A low-pass filter attenuates the noise from the motor.
Connector position
4.4.10 Sensor supply
Supplies for external motor-speed sensors are available between pin PENC_R
A10
(A8) and pin NENC_R
NENC_R
Output voltage is configurable via hardware by internal jumper to +12V or +5V;
the maximum output current is 200 mA.
Actual values for "+12V" and "+5V" are respectively 12.1 V ± 0.5 V and
5 V ± 0.3 V.
Protection
Sensor supply has a current limiter at 200 mA and it is protected against
accidental connection to +B with a diode.

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.
