2.3 Current ratings
Internal algorithms automatically reduce the maximum current limit when heat
sink temperature is above 85°C. Heat sink temperature is measured internally
near the power MOSFETs (see paragraph 6.6.1).
Two-minute ratings are referred to an inverter equipped with a base plate. No
additional external heat sink or fans are used for the 2-minute rating test. Ratings
are based on an initial base plate temperature of 40°C and a maximum base
plate temperature of 85°C.
The inverter can deliver the rated continuous current only if it is adequately
cooled. When it is equipped with its own finned heat sink, a proper dissipation is
obtained by applying a 100 m
it is customer's duty to design an adequate cooling system that can dissipate the
heat produced by the inverter, keeping its temperature below 85 °C. Otherwise,
the inverter will deliver a continuous RMS current lower than the rated one.

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.
