TROUBLESHOOTING (V1.0)
The following table helps you to detect and solve common problems. Before using it and as
a step prior to the solution of problems, make sure that the battery is fully charged and that you
have entered a set of parameters known in the controller, in this order. If you cannot charge the
battery or enter the parameters in the controller, please read first the corresponding possible
causes in the table.
PROBLEM
POSSIBLE CAUSES
ERROR DETECTION/ SOLUTION
Pressing the ON button the motor
does not respond
Low battery
Check voltage in the discharge terminals of
the battery. Charge the battery.
Main fuse damaged
Check the 30A power fuse. Check for possible
short circuits in the wiring / controller.
Replace the fuse when it is safe.
Starting fuse damaged
Check the 0.5A starting fuse. Check for
possible short circuits in the wiring /
controller. Replace the fuse when it is safe.
The Start signal does not reach
the E/S connector
Check the wiring of the whole circuit and that
the battery voltage reaches cable 7 (pink) of
the E/S connector. Replace defective points of
the installation.
There is tension in the Start line but
the motor does not respond
The controller does not transmit
voltage to the throttle
Disconnect the throttle and check that there is
supply voltage in the supply line of the
throttle. Replace the controller if necessary.
The throttle is defective
Once checked that there is supply voltage
check the analogue signal of the throttle.
Replace the throttle if necessary.
When the motor is activated, it
emits an unusual sound or vibrates
excessively
Connection error in the Hall
sensors
Check the connection of the Hall sensors.
Check the continuity on both sides of the
connector. Replace the connector if necessary.
Disconnection of any of the
motor phases or error in the
order of the connections.
Check the connectors of the motor phases.
The controller does not supply
voltage to the sensors correctly.
Disconnect the controller and check the
power supply of the Hall sensors. Connect and
check again. Check that the sensors are
correctly supplied with voltage. According to
the results replace controller and/or motor.
One or more sensors do not
generate position signals.
With the motor in start position, turn the
motor manually. Check if the signals of the
Hall sensors vary by turning the motor.
Replace the motor if necessary.
One or more of the phases have
deteriorated.
Check that the resistance of the windings is
the correct one and that there are no
derivations to the chassis.
Excessive resistance to the
rotation of the motor.
Check manually if the wheel can turn easily.
Solve possible problems in the chassis /
braking system.
