4) LOGIC FAILURE #2
Fault in the hardware section of the logic board which manages the phase' s
voltage feedback. Replace the logic board.
5) LOGIC FAILURE #3
Fault in the hardware section of the logic board which manages the hardware
current protection. Replace the logic board.
6) CHECK UP NEEDED
This is a warning. It is an information for the user that the programmed time
for maintenance is elapsed.
7) INCORRECT START
This alarm signals an incorrect starting sequence. Possible causes:
A) running microswitch failure;
B) error in sequence made by the operator;
C) incorrect wiring;
D) if the default persists, replace the logic.
8) FORW + BACK
The test is carried out continuously. An alarm is signalled when a double
running request is made simultaneously. Possible causes:
A) defective wiring;
B) running microswitch failure;
C) incorrect operation;
D) if the defect persists, replace the logic.
9) HANDBRAKE
The truck does not start because the handbrake switch is opened. Possible
causes:
A) defective wiring;
B) failure of the microswitch;
C) incorrect operation of the operator;
D) if the defect persist, replace the logic.
10) ENCODER ERROR
Two consecutive readings of the encoder speed are too much different in
between: because of the inertia of the system it is not possible the encoder
changes its speed a lot in a short period. Probably an encoder failure has
occurred (e.g. one or two channels of the encoder are corrupted or
disconnected). Check both the electric and the mechanical encoder
functionality. Also the electromagnetic noise on the sensor bearing can be a
cause for the alarm.
11) CAPACITOR CHARGE
Follows the charging capacitor system:
When the key is switched ON, the inverter tries to charge the capacitor
through a power resistance, and check if the capacitor are charged within a
timeout. If this is not true: an alarm is signalled; the main contactor is not
closed.
