Possible causes:
A) the potentiometer is not correctly calibrated;
B) the potentiometer is defective.
12) STBY I HIGH
Test carried out in standby. Check if the current is 0. If not verified, an alarm
is signalled which inhibits machine operations. Possible causes:
A) current sensor failure;
B) logic failure: first replace the logic; if the defect persists, replace the
power unit.
13) SEAT KO
This alarm is present in combi systems (tr pump). The pump
compares the status of the seat input with the value transmitted by the
traction via CAN-BUS. The alarm is signalled if the two values are different in
between.
14) DATA ACQUISITION
This alarm is signalled in the current gain acquisition phase. Wait the end of
the acquisition activity.
15) MAIN CONTACTOR ALARMS
In the combi system (pump + traction) the main contactor is driven by the
traction inverter. So the following description concerns the pump inverter
used independently from the traction inverter. In this configuration the pump
inverter manages its own main contactor.

COIL SHORTED
When the key is switched ON the µP checks the MC driver FF SR. If it
does not react in a correct way to the µP stimulus, the alarm is signalled.
Replace the logic board. The FF SR makes an hardware control of the
current in the MC coil. If this is too high, it opens the MC and the alarm is
signalled.
Check if there are external shortcircuit and if the ohmic value of the MC is
correct; otherwise replace the logic.
- DRIVER SHORTED
When the key is switched ON, the µP checks that the MC coil driver is
not shorted; if it is, this alarm is signalled; replace the logic board.
- CONTACTOR DRIVER
When the initial diagnosis is finished, the traction logic closes the MC and
checks the voltage on the Drain of the driver. If this is not low, an alarm is
signalled.
Replace the logic.
- CONTACTOR OPEN
The main contactor coil has been driven by the logic board, but the
contactor does not close. Two possible reasons:
A) the wires to the coil are interrupted or not well connected.
B) the contact of the contactor is not properly working.
16) AUX OUTPUT KO
The µP checks the driver of the electromechanical brake. If the status of the
driver output does not correspond to the signal coming from the µP, the
alarm is signalled. Replace the logic.
17) HIGH TEMPERATURE
Controller temperature is greater than 75 °C. The maximum current is
reduced proportionally to the temperature increase. The controller stops at
100 °C.
If the alarm is signalled when the controller is cold:
A) check the wiring of the thermal sensor;
B) thermal sensor failure;
C) logic
failure.
