1. GENERAL COMMENTS
1.1 OMFB RADAR II Radio remote control systems
OMFB radio remote control systems have been developed specifically for use on automotive
vehicles, thus taking into consideration the specific problems of automotive applications.
Special care was taken with the following factors:
• defining the type of housing to use;
• configuration of the manual commands always available in case of radio transmission
failure;
• radio channel engineering to ensure the proper capacity in terms of distance and transmitting
conditions.
The OMFB RADAR II radio remote control system essentially consists of the following components:
• 3 receivers:
1. 2-channel receiver (2 CH)
2. 2-channel receiver, trailer configuration (2CH RIM)
3. 4-channel receiver (4 CH)
• 2 transmitters:
1. RADAR II Midi transmitter (to control 2- and 4-channel systems)
2. RADAR NEW TXF transmitter (to control 2- to 12-channel systems)
The OMFB RADAR II system is completely modular, and up to 10 different configurations may be
obtained by combining the above components appropriately.
Each paragraph of this section describes the individual system components of the RADAR II radio
remote control system.

4.1 Power supply
RADAR II radio remote controls may be powered with a voltage between 10V and 28V
in direct current.
The power supply line (+12/24V batt and ground) should lead to the receiver directly from
the main source (battery or stabilized power source), with cables adequately sized for the
load to be carried (cross-section of at least 1 mm^2), also using a safety fuse.
The power supply line to the receiver must be kept locked, or under a switch dedicated
specifically to the radio remote control system, or under an appropriately sized battery
disconnector.
It is essential that the radio remote control system never be powered while the
vehicle is running: the installer is responsible for informing the system end user
of this fact.

4.3 Setting the output type (Single-/Double-Acting)
The typical device configuration of OMFB radio remote controls is to control systems made
up of electric pumps and solenoid valves.
The OMFB Radar II receiver is equipped with a series of 4 microswitches, shown in the
figure: each microswitch allows the installer to set, for each individual output, the function
as double-acting or single-acting, thus it allows the installer to define whether or not the
AUX output must be enabled parallel with each individual output.
In the case of configuration with electric pump, if the microswitch for a given output is
set to OFF (away from the board), the electric pump will not be enabled parallel to this
output; if instead the microswitch is set to ON (thus facing the board), the electric pump
will be enabled parallel to this output.

4.4 Output connectors
The 3 versions of receivers have the following low-voltage outputs (unstable relay type,
“deadman” activation):
Radar II 2 CH Receiver
• 2 outputs to activate electrical devices
(such as solenoid valves or relays), with a
maximum absorption of 8 A each. The two
outputs are enabled by the UP and DOWN
functions of channel 1, respectively, and
are not clean contacts, but reflect the sup-
ply voltage of the device (9 ÷ 28V);
•1 AUX output (see 4.3 for more informa-
tion) with a maximum absorption of 8 A.
Radar II 2 CH RIM Receiver
• 2 outputs to activate electrical devices
(such as solenoid valves or relays), with
a maximum absorption of 8 A each. The
two outputs are enabled by the UP and
DOWN functions of channel 2, respec-
tively, and are not clean contacts, but
reflect the supply voltage of the device
(9 ÷ 28V);
• 1 AUX output (see 4.3 for more informa-
tion) with a maximum absorption of 8 A.
Radar II 4 CH Receiver
• 4 outputs to activate electrical devices
(such as solenoid valves or relays), with
a maximum absorption of 8 A each. The
4 outputs are enabled by the functions
UP and DOWN of channel 1 and chan-
nel 2, respectively, and are not clean
contacts, but reflect the supply voltage
of the device (9 ÷ 28V);
• 1 AUX output (see 4.3 for more infor-
mation) with a maximum absorption of
8 A.
WARNING: In the versions with 6 CH, 8
CH, 10 CH, 12 CH, the 2 or 3 receivers
have the same technical specifications
as the 4CH.

4.5 Electrical specifications of the admissible loads
The output stage of OMFB radio remote controls uses unstable relays.
The systems are sized for a maximum load of 8 A+ 8 A inductive simultaneously on two
outputs (8 A on one output and 8 A on the AUX output).
Where the loads are actually close to this limit, we suggest checking with the OMFB staff
to determine whether the type of load may create problems: the information to report
includes: type of load (coil, solenoid valve, remote switch, etc.), electrical specifications
of the load (generally shown on the labels of the load itself: absorbed power, i.e., 30W,
supply voltage, i.e.,12V, absorbed current, i.e. 4 A), temporary activation cycle of the
load (1 minute of consecutive activation, 3 minutes of rest, etc.).
The more accurate the information the lower the risk that problems may arise due to
neglected factors.
The relays are sized to 16 A so as to reduce to a minimum the risk that the relay will
stick: in any case, the mushroom-head emergency control, or from the transmitter, cuts off
power to the outputs and thus ensures the absolute safety of the system.
5. INSTALLATION AND MECHANICAL FASTENING OF THE RECEIVER
5.1 General comments
The receiver must be installed using the 4 through-holes already present on the
receiver, and must not be opened or drilled for any reason.
For applications involving strong vibrations, it is recommended to insert the
appropriate anti-vibration material between the external housing of the receiver
and the support to which it is fastened.
Any opening, drilling or similar operations on the receiver not previously agreed
upon with OMFB will void the product warranty.
The following factors must be taken into consideration when choosing the receiver position
on the vehicle:
• The red mushroom-head Emergency Stop button must be easily accessible;

• The best reception capacity is obtained by placing the receiver as high as possible
off the ground;
• Whenever possible, the receiver should be clearly visible from the transmitter
work area.
• The field radiates concentrically from the antenna; in the case of receivers without
external antenna, the latter is aligned with the receiver box.
As already mentioned in the previous paragraph:
The power supply line (+12/24V batt and ground) should lead to the receiver directly from
the main source (battery or stabilized power source), with cables adequately sized for the
load to be carried (cross-section of at least 1 mm^2), also using a safety fuse.
The power supply line to the receiver must be kept locked, or under a switch dedicated
specifically to the radio remote control system, or under an appropriately sized battery
disconnector.
It is essential that the radio remote control system never be powered while the
vehicle is running: the installer is responsible for informing the system end user
of this fact.
5.2 Positioning the receiver
Install the receiver with the cable input facing down, never upwards.
5.3 Fastening the receiver
To fasten the receiver you must take advantage of the studs already present on the receiver
box. Do not drill any holes in the box, under penalty of voiding the product warranty.

5.4 Insertion in additional housings
The receiver may be inserted in an additional housing as long as it is made of plastic
and not metal.
Insertion in a metal housing must absolutely be agreed upon and assessed with OMFB
staff to avoid unpleasant malfunctions.
5.5 Installing multiple side-by-side receivers
In the RADAR II 2CH+2CH, 6 CH, 8 CH, 10 CH and 12 CH configurations, which involve
multiple receivers installed side by side, these must be installed at a minimum distance of
30 mm from one another.
6. EMERGENCY STOP
6.1 Emergency Stop engaged by the Transmitter
(Regarding the RADAR NEW TXF transmitter, see the corresponding manual)
The emergency stop command predominates over all other conditions, and thus may be
activated even if the key for another transmitter function is inserted due to a breakdown
or carelessness.

To deactivate the Emergency Stop function (indicated by a continuous buzzer sound emitted
by the receiver) and restore system operation, press the green Reset button.
6.2 Emergency Stop engaged by the Receiver
To activate the Emergency Stop function from the receiver press the mushroom-head STOP
button (the buzzer inside the receiver emits a continuous sound).
To restore system operation, release the push-button by turning it clockwise and press
the green Start button.
7. PROGRAMMING PROCEDURES
7.1 Programming
This procedure is necessary if you have received a transmitter and receiver(s) separately.
Before using a new TXF transmitter, communication has to be created between the
transmitter and the receiver(s).
To do this please follow the below described programming procedure.
ATTENTION: make sure the receivers have not already been programmed, if they have,
cancel the program and reprogram with the new transmitter.
1. Power up the receiver (insert the battery disconnector and any other switch that may be
installed in series with the receiver power supply);
2. On the transmitter: make sure the TX LED lights up when a function button is pressed
in columns A, B, C;
3. On the receiver: press the red emergency mushroom-head button: the buzzer inside
begins to emit a continuous sound;
4. On the receiver: put a magnet next to the “Learning Zone”: the buzzer inside
the receiver will emit an intermittent sound;

5. On the transmitter: press one of the function buttons (channel 1 Up/Down or channel 2
Up/Down) in the column on which you wish to program the receiver (A, B or C).
6. On the receiver: the sound issued by the buzzer returns;
7. On the receiver: release by turning the red emergency mushroom-head button;
8. On the receiver: press the green button;
9. Make sure all functions connected to the radio remote control system are correctly
activated.
RESET OR PROGRAM CANCELLING PROCEDURE
Each receiver stores up to 5 distinct transmitter codes. When the memory is full, the receiver
signals it by emitting an intermittent high frequency sound. To reset the memory, proceed
as for programming up to step 4 and keep the transmitter at hand. When the continuous
beep switches to alternating beeps, within 5 seconds the alternating beeps will emit a
sound at a different frequency. Now, after releasing the emergency button, press the green
button on the receiver.

8. FUNCTIONAL TESTING PROCEDURES
8.1 General comments
This section gives the block diagrams of the procedures to follow in case you encounter
operating problems with RADAR II radio remote control systems: these procedures
should be applied whenever problems occur and before contacting OMFB staff.
Since malfunctions encountered in systems equipped with radio remote control often may
not be malfunctions caused by the remote control itself but by the overall system, applying
these procedures can significantly reduce the time needed to identify and solve problems.
We therefore strongly recommend that you apply them whenever you are faced with any
problem on OMFB radio systems or systems equipped with OMFB radio remote control.
The following procedures are described:
• Functional testing of the receiver unit
• Functional testing of the NEW TXF transmitter
• Testing the STD Programming
• Testing the REED programming
• Testing of the power outputs
Starting from the blocks labeled “Start” and following the block diagram step-by-step
for each part to be checked, you should eventually manage to solve the most common
problems or in any case identify the specific type of problem.
“Diamond”-shaped blocks are “decision blocks”, which ask a question and lead in a given
direction based on the answer (Yes, No).
A block in one procedure may lead to another procedure. In this case, you must begin at
the start block of the procedure indicated.
You may come to a block recommending that you “Request a return”. In this case, the return
request must also indicate the contents of the block itself, thus for example “Indicating
possible problems on the power supply line” or other: this information must be reported
along with the return request, since it may significantly reduce the time needed to solve
the problem and, especially, may assist OMFB staff in identifying problems not caused by
OMFB radio remote controls but by other vehicle systems.
Should you arrive at a block labeled “Request a return,” in order to understand the cause
of the problem it may be very helpful to photocopy the procedure followed and mark the
path taken through the block diagram leading to the return request, and fax this copy to
the OMFB staff.
