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 main-
tenance 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;
If the defect persist , replace the logic.
10. 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.
