AL_64: FUNCTION ► Timeout actuator 2 ► Only with external limit switches, if the actuator doesn't reach the fi nal position within a preset time (disabled for this ma-
chine). Check the connections, electrical and mechanical conditions of the actuator. If no external causes are detected, this may indicate a faulty actuator pilot stage.
AL_65: FUNCTION ► Actuator 2 ammeter ► Check performed on software that intervenes if the current read on the output remains above the Nominal Current
parameter for the time set in the Nominal Time parameter. If the current drops below the threshold, the time is instantly reset.
AL_66: FUNCTION ► Actuator 2 overcurrent ► Check performed on hardware that intervenes in case of output short circuit, at about 40A for 10us.
AL_67: FUNCTION ► Incorrect limit switches actuator 2 ► Check the actuator limit switch status reading. The alarm is generated (if envisaged by the type of actuator
used) when at least two limit switches are detected as being simultaneously open. Check the quality of the connections, mechanical and electrical status of the limit
switches.
AL_68: FUNCTION ► Timeout actuator 3 ► Only with external limit switches, if the actuator doesn't reach the fi nal position within a preset time (disabled for this ma-
chine). Check the connections, electrical and mechanical conditions of the actuator. If no external causes are detected, this may indicate a faulty actuator pilot stage..
AL_69: FUNCTION ► Actuator 3 ammeter ► Check performed on software that intervenes if the current read on the output remains above the Nominal Current
parameter for the time set in the Nominal Time parameter. If the current drops below the threshold, the time is instantly reset.
AL_70: FUNCTION ► Actuator 3 overcurrent ► Check performed on hardware that intervenes in case of output short circuit, at about 40A for 10us.
AL_71: FUNCTION ► Incorrect limit switches actuator 3 ► Check the actuator limit switch status reading. The alarm is generated (if envisaged by the type of actuator
used) when at least two limit switches are detected as being simultaneously open. Check the quality of the connections, mechanical and electrical status of the limit
switches.
AL_80: TRACTION ► Overtemperature ► It activates when the temperature on the function power mosfets exceeds 90°C.
AL_81: TRACTION ► Damaged power ► During the switch-on sequence, a series of tests are carried out to verify the correct operation of the mosfets and their drivers.
AL_82: TRACTION ► Main fuse faulty ► At switch-on, check that the potential diff erence at the drive fuse ends is zero.
AL_83: TRACTION ► Main contactor faulty ► Alarm generated if the main traction relay does not close after the switch-on sequence (check).
AL_84: TRACTION ► Main contactor faulty CC ► Alarm generated if the main traction relay is already closed at switch-on.
AL_85: TRACTION ► Traction output overcurrent ► Check performed on hardware that intervenes in case of output short circuit, at about 300A for 10us.
AL_86: TRACTION ► Traction Output ammeter ► Check performed on software on the output current according to the formula (I²t).The board allows for a current
above the nominal current (In) for a t time defi ned as follows:
with
AL_87: TRACTION ► Motor reading ► If the current reading circuit provides incorrect values (outside certain thresholds considered unreliable).
AL_88: TRACTION ► Electric brake anomaly ► The anomaly occurs if the board does not sense any load on the electric brake output.
AL_89: TRACTION ► Pedal faulty ► Alarm generated in case of: The voltage of the gear pedal signal is greater than its maximum reference voltage; the voltage of the
gear pedal signal is greater than 2V and the Gear Pedal micro does not close.
AL_90: TRACTION ► Pedal pressed ► The anomaly occurs if the gear pedal is pressed at switch-on.
AL_91: TRACTION ► Encoder error ► Alarm generated if the encoder on the traction motor is detected as damaged or absent. Check the connections and replace
the component if necessary.
AL_92: TRACTION ► Traction motor thermal switch ► Traction motor overheated, check cause and contact service assistance.
