DUALACE2 NEW GENERATION Standard is equipped with a 23-poles Ampseal
connector like that of the figure. Each of the 23 pins is referred to as "A#", where
"A" denotes the connector name and "#" the pin number, from 1 to 23.
For each I/O pin, the default Zapi function is indicated. The function of each pin
can be changed in the customized software.
Some I/O pins can have special functionality depending on controller
configuration.

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.
