Models and Market

This document applies to all Smartlift and Digital Control units.

Information

This document is to assist in fault finding for SMARTlift or Digital Control systems which will not start up. Try the following suggestions to find the reason that the unit is not starting:

POSSIBLE REASON

Suggested Actions

Main Key is not turned ON

 

Battery Isolators not turned ON

(Dangerous Goods Model only)

E-Stops not released

 

There are three E-Stops fitted to the Sidelifter.

1. Front E-Stop.

Located on the front coupling area of the Sidelifter.

Twist the E-Stop button clockwise to release.

 

2. Main Control Box E-Stop.

Located on the Main Control box.

Twist the E-Stop button clockwise to release.

 

3. Remote E-Stop.

Located on the Radio Remote Control Transmitter.

Twist the E-Stop button clockwise to release.

Radio Remote not Started

When the main key is ON and all the E-stop buttons are released then the system can be started.

Press the restart button on the radio remote. The green battery indicator LED should be ON. If not then replace the transmitter battery with a fully charged one. Press the restart button again.

 

The system should have started. Check that:

  • On the main control panel the green E-Stop Circuit light is ON showing that E-stop circuit has been released.
  • The SMARTlift display screen is active and should show some graphics and text.

 

Flat Batteries

There are two batteries on the Sidelifter:

  • ECU battery (for SMARTlift electronics)
  • Main battery (to start the powerpack engine)

 

ECU Battery

Push the battery selector switch up on the SMARTlift display panel to read the voltage of the ECU battery. The ECU battery voltage should be above 12 volts. If the voltage is below 11 volts then the battery voltage is too low to start the system. Refer to "Starting the system with a flat ECU battery"

 

Main Battery

Push the selector switch down on the SMARTlift display panel down to read the voltage of the main battery. The main battery voltage should be above 12 volts. If the voltage is below 11 volts then the battery voltage may be too low to start the system.

If the voltage is too low, charge the main battery or attach jumper leads from another vehicles battery and then retry the start procedure. The main battery is located on the power pack.

Starting the System with a Flat ECU Battery.

Step

Description

1

Check the main key is ON.

2

Check the battery isolators are ON (if the trailer has the Dangerous Goods Operation options).

3

Check the 3 E-Stops are released.

4

Press and hold the black override button on the left side of the main control box.

Hold this button until step 9 of this procedure. The green light on the front of the main control box should be ON indicating that the E-Stop circuit is released.

5

Turn the main key to the Glow position (the yellow glow lamp turns on) and hold it there for 10 seconds.

6

Turn the main key to the Start position until the engines starts then return it to the ON position.

7

Continue to hold the black button in until the engine has run for 1-2 minutes.

8

Restart the remote by pushing the Restart button on the radio remote.

9

Wait 10 seconds and then release the black override button. The engine should keep running. Allow the engine to run for about 10 minutes to ensure the batteries get recharged enough for the next time the system will be used.

If the engine stops and the green E-Stop light goes out then the battery is still does not have enough charge to sustain operation. You may need to repeat this procedure and keep the engine running for a longer period before restarting the remote and releasing the override button.
