INSTALLATION - TWIN AXLE
When you use the manoeuvring system for a twin axle caravan, please check the following:
Permissible overall weight twin axle (2 motors) 2000kg (1750kg on 18% gradient)
Permissible overall weight twin axle (4 motors) 3000kg (2350kg 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 9S/T) on the control unit to the twin
axle position (Fig. 9T), 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
systems.
Follow the procedure
INSTALLATION - 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
INSTALLATION - 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
(see wiring diagram pg. 11).
Note:
When installing the four motors it will be necessary to use
one
higher capacity battery to supply both sets of
manoeuvring systems (including two electronic control units and two 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 9S/T) on the control
unit to the twin axle position (Fig. 9T), 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 needs 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. 10A). The green LED on the remote control handset (Fig. 10H)
will start to flash slowly.
• Press the reset button (Fig. 9A) on the control unit. All three LED’s on
the control unit (Fig. 9B, 9C & 9D) will flash slowly.
• Press both forwards (Fig. 10B) and reverse (Fig. 10C) button on the
remote control handset for about 3 seconds. 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. 9B) and on the remote control handset (Fig. 10H) 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 table of contents.
