Instruction for use of the forklift with the triple pivot battery
36
the lifting motor failed to act, the power supply loop of lifting contactor will be disconnected immediately.
If the lifting motor is in motion, cut off the power supply loop of lifting contactor after 10s delay (fed for
the completion of one lifting motion).
f) Display of fault code
The instrument possesses the fault display function of electronic control. The fault category is represented
in 2 digital decimal number and a number of fault categories can be displayed. When there is a fault in the
part of electronic control, the fault indicator light on the gauge is lit at the same time. If more than two
faults coincide, the "Fault Code Window" always shows the fault, which is shown finally (Determined by
the electronic control device). When this fault is troubleshot, the next one will be on display until all faults
have been eliminated and the "OK" is shown.
Rational table between the fault codes and phenomenon prompts
On the controller housing, there are the red and yellow LED lamps. The different flashings represent various
faults, as shown in the following table:
The controller has no power supply, because there is no electricity in the
battery or a fault on the line
The yellow light is flashing
The controller is working properly
Both the yellow and red lights are constantly lit
The controller is updating the software
Both the yellow and red lights are flashing
The controller has a fault
1. The connecting wire U, v or W of motor is short-circuited.
2. Wrong setting of motor parameters
3. Controller fault
1. The U, V, W are short-circuited relative to the vehicle body (The motor stator short-
circuited)
2. Controller fault
1. Connect the external loading at the capacitor bank (B + Terminal) to prevent the
capacitor from charge.
2. Check the capacitance voltage under the monitoring menu.
Controller Severe Undertemp.
1. The controller is working under the limiting environment (low than -40°C).
2. Check the controller temperature under the monitoring menu.
Controller Severe Overtemp.
1. The controller is working at the limiting temperature (Higher than 95°C).
2. Vehicle overload.
3. Improper installation of controller.
4. Check the controller temperature under the monitoring menu.
1. Wrong setting of battery voltage parameters.
2. The battery power runs out.
3. The inner resistance of battery is too high.
4. In driving, the battery is not connected.
5. Check the capacitance voltage under the monitoring menu.
6. The B + fuse burn or the master contactor unclosed.
