Speed-sensor signals are acquired through the quadrature peripheral of the
microcontroller.
Protection
Encoder inputs are protected against short circuits to +B and -B and have ESD
suppressor to -B for ESD protection.
Connector position
It is important to verify the wiring by ensuring that encoder signals are not
disturbed by motor currents or by electric motor brake.
For more details about encoder installation see also paragraph 5.2.6.
The encoder resolution, the motor pole pairs and other pieces of information are
specified in the Zapi Console by means of an head line like the following:
Where:
A2: DUALACE2 NEW GENERATION.
M: Master μC (S: Supervisor μC).
T: Traction controller (P: pump controller).
2: Motor poles pair number.
B: 64 pulses/rev encoder.
2: Motor control generation.
ZP1.21: Firmware version.
The encoder resolution is encoded in the last letter of the first batch as:
Code:
Pulses/rev: 32
Code:
Pulses/rev: 1024
Encoder resolution can be changed through the dedicated parameters. See
paragraph 8.2.7.

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.
