same bulb. In this case of driving car lamp, the appropriate module input of position light (left or right)
should be connected with appropriate fog light input (left or right).
CONNECTING IN CASE OF SINGLE-FILAMENT BULB PERFORMING TWO
CONNECTING IN CASE OF SINGLE-FILAMENT BULB PERFORMING TWO
FUNCTIONS: POSITION AND STOP LIGHT
FUNCTIONS: POSITION AND STOP LIGHT
This function is designed for the cars where the position light and stop light are realized on a single
filament bulb. The position light function is realized by applying ca. 4V RMS voltage to the bulb. The
stop light is realized by applying 12V to the same bulb. In this case of driving car lamp, the appropriate
module input of position light (left or right) should be connected with stop light input.
DIRECTION LIGHTS CONNECTING
DIRECTION LIGHTS CONNECTING
In MP3S version there is applied additional function informing that the one of direction lights bulb is
broken similarly as the car direction lighs bulb breakage is indicated. When the car direction lights bulb
is broken, the direction lights blink about two times quicker. In case of breaking the trailer direction
lights bulb, the module "simulates" breaking of car direction lights bulb wherethrough the same
"quicker blinking" effect is achieved. This function is required by low in some European countries. In
this case, the module is connected with cutting the car rear direction lights wires accordingly with
installation diagram A.
TEST OF TRAILER ELECTRICAL CONNECTION AND DISCONNECTION
TEST OF TRAILER ELECTRICAL CONNECTION AND DISCONNECTION
Test of trailer electrical connection is provided through checking if the trailer stop light bulbs
are connected. The bulb filaments perform as a sensor for the testing circuit. Minimal power
load for proper work is 10 W.
CAR ALARM INTEROPERABILITY
CAR ALARM INTEROPERABILITY
The control unit detects whether the trailer is unplugged and after approx. 1 second activate
output "Alarm Info" setting it for approx. 1 second to ground level (max. 2A). This output can
be connected to an existing car alarm or GPS monitoring. For example, this output could be
connected to the door, hood or trunk switch, the ground level pulse will simulate the switch
activation and trigger the alarm.
PARKING SENSORS INTEROPERABILITY
PARKING SENSORS INTEROPERABILITY
In the cars, where the ultrasonic parking sensors without “permanent obstacle” learning function are
installed (the trailer becomes a permanent obstacle), the sensors can be blocked for the time when the
trailer is plugged in. The module has a current output (max. load 2A) which connects to GROUND
when the trailer is unplugged. Detection of trailer connection causes that the GROUND level will be
disconnected on that output. This output could be used to powering the ultrasonic sensor control unit
providing the ground level to it.
LED-INFO STATUS OUTPUT (OPTION)
LED-INFO STATUS OUTPUT (OPTION)
The external LED connected to this output indicates the following states:
LED
Module status
off
Trailer unplugged
permanently on Trailer plugged
flashes
One of the direction indicator light bulb is broken
In a situation when the testing of the module installation cannot be done with a
real trailer, a
TMP-01
tester can be used for simulating full electric driving load
of the module outputs. The tester is available from
