The control unit (32), which is mounted inside your caravan, is responsible for controlling the manoeuvring
system.
The control unit has three LED’s, one pushbutton and one slide switch (Fig. 3):
Green LED (Fig. 3B): Power LED continuously illuminated when system is activated (by moving slide switch to
“On”-I). If the remote handset far away from the control unit, beyond the availably distance, this LED will go
out.
Blue LED (Fig. 3C): Error message LED concerning caravan battery:
Blue LED is blinking (2 times blinking, break, 2 times blinking, break etc.): Battery voltage too low (<10
Volt). Battery needs to be recharged.
Blue LED is blinking (4 times blinking, break, 4 times blinking, break etc.): Battery Voltage too high (over
charged). Try to discharge the battery by turning on a user (for example a lamp or water-pump).
Red LED (Fig. 3D) is blinking (6 times blinking, break, 6 times blinking, break etc.): Amp overload protection is
activated. Wait about 60 seconds and try again.
In general all error messages will reset automatically after one minute. If this is not the case, reset the
electronics of the manoeuvring system by switching off the system via the isolation switch and the remote
handset for at least 15 seconds and then turning it on again.
The Reset Button (Fig. 3A):
The remote handset and the control unit are synchronised with each other in the factory. If the control unit or
the remote handset is replaced, they must be re-synchronised as described below:
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 12 Volt is present at the control unit.
Please ensure that the battery isolation switch is on.
Activate the remote handset by sliding the slide switch to “On”-I (Fig. 5A). The green LED on the remote
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 handset for about 3 seconds.
Then the remote 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 handset
(Fig. 5H) will illuminate continuously.
The single-twin axle function switch (Fig. 3S/T):
The ENDURO
®
EM303
+
caravan manoeuvring system is suitable for both single axle and twin axle caravans. You
just need to pull the single-twin axle function switch (Fig. 3S/T) on the control unit, so that the manoeuvring
system can be used for a single-axle caravan or a twin-axle caravan (for 2 motor use but also for 4 motor use).
In the twin axle function the all wheels will drive but at a different speed.
The switch standard pre-selected for single axle use (Fig. 3S). For twin axle use, just move the switch to the
twin axle position (Fig. 3T). When move the single-twin axle function switch, the battery power isolation switch
must be turned off.
Bluetooth adapter connector (Fig. 3E):
The control unit can be expanded with an optional Bluetooth adapter (ENDURO
®
BC101) for controlling the
manoeuvring system with a Smartphone or tablet. When connecting the cable, the battery power isolation
switch must be turned off.
