When you drive straight forwards or reverse (press button B or C), it is also possible to adjust the direction by
additional pressing button D or E (when driving forwards) or button F or G (when driving reverse).
In addition, the ‘right forward’ (E) and ‘left reverse’ (F) buttons or ‘left forward’ (D) and ‘right reverse’ (G)
buttons may be pressed at the same time to turn the caravan around on its own axis without moving forward or
backward (this function just can work under the “single-axle function”).
When you switch within 2 seconds from forward driving to reverse driving (and the other way around), a small
delay of 1 second will appear to protect the electronics and the motors.
The slide switch (Fig. 13A) also acts as an “Emergency stop”.
The automatic engaging system:
To activate the automatic engaging system of the motor powered rollers on the tyre, press the two buttons for
engaging (Fig. 13I) or disengaging (Fig. 13J) for at least three seconds. The blue LED (Fig. 13K) will blink fast
during these three seconds and every second there will be a beep. This warns you that the system will be
activated!
Engaging: After these three seconds the motor powered rollers will be pressed against the tyre, and the blue
LED will illuminate constant. Now you can release the two buttons. When the motor powered rollers are pressed
on the tyre strongly enough you hear a short beep, the blue LED will switch off and the system is ready to use.
Disengaging: after these three seconds the motor powered rollers will be released from the tyre, and the blue
LED will illuminate constant. Now you can release the two buttons. When the motor powered rollers are
completely disengaged you hear a short beep, the blue LED will switch off and is the system ready for
transport.

EM505FL is provided with a level display on the remote handset (Fig. 13O, 17 & 18). During
manoeuvring you can already see if your caravan is level.
The display shows by orange and red LEDs which side is the lowest. This is made visible in the longitudinal
direction (front/rear) and in the width direction (left/right). With the aid of the jockey wheel, the "longitudinal
direction" level to be adjusted, and with the help of, for example, a drive block or leveller under the wheel, the
"width direction" level can be adjusted. If the caravan is level (approximate) only the green centre LED will light
up.
The remote handset switches off:
After 3 minutes, if no button is pressed: After 2 minutes the buzzer will beep for 5 times with a repetition
after 3 minutes. Than the system switches in the “stand-by” modes.
After 6 minutes, if one of the movement buttons is permanently held down: After 5 minutes the buzzer will
beep for 5 times with a repetition after 6 minutes. Than the system switches in the “stand-by” modes.
The power LED (Fig. 13Q), the manoeuvring system LED (Fig. 13V) and the communication LED (Fig. 13H) turn
off and the remote handset is in the “stand-by” modes which means that there always will be used some
current which causes the battery to go down. So always make sure the remote handset is turned off by the
slide switch.
To reactivate the remote handset, move slide switch down and after approximately 1 second up again.
Error messages via the remote handset:
Communication LED (Fig. 13H) off, no buzzer: remote handset is turned off and also system is not
activated
Communication LED (Fig. 13H) continue on, no buzzer: remote handset is turned on and system is
activated and ready to use.
Communication LED (Fig. 13H) is blinking, no buzzer: no communication between handset and control unit.
This could be because of too much distance between remote handset and control unit, or the battery
isolation switch for manoeuvring system is not turned on or that there is a distortion signal disturbing the
communication. As soon as connection is good again the green LED will be continue on and the system is
ready to use.
Caravan battery LED (Fig. 13N) is blinking in combination with buzzer (2 times blinking, break, 2 times
blinking, break etc.): Battery voltage too low (<10V). Battery needs to be recharged.
Caravan battery LED (Fig. 13N) is blinking in combination with buzzer (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).
Overload LED (Fig. 13L) is blinking in combination with buzzer (6 times blinking, break, 6 times blinking,
break etc.): Amp overload protection is activated. Wait about 60 seconds and try again.
Remote handset battery LED (Fig. 13M) is blinking, no buzzer: The internal battery is near empty and
needs to be recharged.
Charging battery in the remote handset:
When the battery is empty (Remote handset battery LED (Fig. 13M) is blinking), it needs to be recharged.
Connect the USB cable to the mini USB port on the remote handset (Fig. 13R).
Connect the other end of the cable into a USB charger (not included, minimal output 1A).
