24. HIGH TEMPERATURE
Chopper temperature is greater than 75°C. The maximum current is reduced propor-
tionally to the temperature increase. The chopper stops at 100°C.
If the alarm is signalled when the chopper is cold:
a) check the wiring of the thermal sensor;
b) thermal sensor failure;
c) logic failure.
25. THERMIC SENSOR KO
The range of inverter temperature sensor is always checked and a warning is sig-
nalled if it is out of range.
When this alarm is signalled, check the connection of the sensors.
26. CAN BUS KO
The diagnosis of the CAN-BUS line is present only if the inverter uses this link (de-
pends on the software version). It is signalled if the inverter does not receive any
message from the CAN-BUS line. First of all, check the wiring. If it is ok, the problem
is on the logic board, which must be replaced.
27. BATTERY LOW
If the "battery check" option is ON, a battery discarge algorithm is carried out. When
the charge level is 10% , this allarm is signalled and the current is reduced to the half
of the programmed level.
