Finally find a suitable place for the remote control handset wall holder (32) and fix this by the supplied screws
(out of reach of children or other unauthorised people).
Installation of the caravan manoeuvring system is now complete.
INSTALLATION – TWIN AXLE
This manual describes the general installation and use of the manoeuvring system for single axle caravans.
When you use the manoeuvring system for a twin axle caravan, please check the following:
Permissible overall weight twin axle (2 motors)
1800kg (1500kg on 18% gradient)
Permissible overall weight twin axle (4 motors)
2500kg (1800kg on 18% gradient)
2 motors:
The procedure for installing a 2 motors manoeuvring system on a twin axle caravan is the same as for a single
axle caravan. The electronic control unit (4) only must be prepared for twin axle use:
Turn off the battery power isolation switch and move the single/twin axle function switch (Fig 3S/T) on the
control unit to the twin axle position (Fig. 3T), so that the manoeuvring system can be used for a twin axle
caravan. In the twin axle function when making curves, all wheels will drive but at a different speed.
4 motors:
The procedure for installing a 4 motors manoeuvring system on a twin axle caravan is similar than for a single
axle caravan but then with two sets of manoeuvring system.
Follow the procedure for installing the mechanical components twice: one time for the manoeuvring set
mounted in front of the twin axle and one time for the manoeuvring set mounted behind the twin axle.
Follow the procedure for installing the electrical/electronic components twice: one time for the
manoeuvring set mounted in front of the twin axle and one time for the manoeuvring set mounted behind the
twin axle.
Note: When installing the four motors it will be necessary to use one higher capacity battery to supply both
sets of manoeuvring system (including two electronic control units and two of battery power isolation switches).
Do not use two separate batteries for a 4 motors manoeuvring system on a twin axle caravan.
Now both electronic control units (4) must be prepared for twin axle use:
Turn off the battery power isolation switch and move the single/twin axle function switch (Fig 3S/T) on the
control unit to the twin axle position (Fig. 3T), so that the manoeuvring system can be used for a twin axle
caravan. In the twin axle function when making curves, all wheels will drive but at a different speed.
Finally both electronic control units (4) must be prepared for the use of only one remote handset (32). The
remote handset need to be synchronised with both electronic control units using the following procedure:
Check the installation in accordance with the installation instructions and ensure that the drive rollers are
not applied. Check that the battery is properly connected, check the condition of the battery and that a
voltage of 12V is present at the control unit.
Please ensure that both battery isolation switches are on.
Activate the remote control handset by sliding the slide switch to “On”-I (Fig. 5A). The green LED on the
remote control handset (Fig. 5H) starts to flash slowly.
Press the reset button (Fig. 3A) on the control unit. All three LED’s on the control unit (Fig. 3B, 3C & 3D)
will flash slowly.
Press both forwards (Fig. 5B) and reverse (Fig. 5C) button on the remote control handset for about 3
seconds. Then the handset buzzer will give a short beep to confirm that the synchronisation is complete.
After successful synchronisation, the green LED on the control unit (Fig. 3B) and on the remote control
handset (Fig. 5H) will illuminate continuously.
Repeat this procedure with the second electronic control unit.
Turn the remote handset “Off” and then “On” again so both control units will be activated.
The installation of the caravan manoeuvring system for twin axle use is now complete. For details of the
operation, use and all the LED and button functions, please refer to the standard chapters of this manual.
