For critical functions, when good diagnostics coverage is necessary, it is
recommended to use two digital inputs for plausibility check, for example
to use both normally open and normally closed contacts.
Protection
Each digital input has a 22 nF capacitor to -B for ESD protection.
Circuit
Input impedance to GND of active high digital inputs in standard Zapi
configurations are listed below. Custom hardware may feature different
impedance values.
Inverter voltage
Input impedance
(Active high)
Digital inputs on A1, A2,
activated when closed to -B. Their behavior can be changed by special HW
configuration, as to be activated when closed to +B.
Connector position
Microswitches
It is suggested that microswitches have a contact resistance lower than 0.1 Ω
-
and a leakage current lower than 500 µA.
-
In full-load condition, the voltage between the key-switch contacts must be
lower than 0.1 V.
-
If the microswitches to be adopted have different specifications, it is
suggested to discuss them with Zapi technicians prior to employ them.
4.4.3 Analog inputs
Analog inputs are for functions such as accelerator or brake references and they
are acquired through a 10-bit analog-to-digital converter (resolution is given by
voltage excursion over 1024 levels).
Circuit
Input impedance and maximum frequency for analog inputs in standard Zapi
configurations are listed below. Custom hardware may feature different values.

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.
