Model 3022
TRANSMITTER
Important! Read
Before Installation
The MULTI-CODE 3022 transmitter has been
designed to provide great reliability and safety, but it must
be installed correctly. Read the enclosed instructions
carefully.
The Model 3022 may be used for a variety of purposes,
and wherever remote signaling is desirable, as specified
by FCC regulations. If this transmitter is to be used in an
application which may be safety related be sure to take
special precautions. Linear Corporation has taken every
step to insure the best possible product, but you must be
certain to install the 3022 transmitter correctly.
Before installing the 3022 transmitter, open it up by
removing the four screws which secure the top of the case.
You will note that there is a terminal block (see figure 1), to
which you will secure the wires coming from your device.
Run your wire through the strain relief fitting, leaving
enough wire to provide adequate length for stripping.
YOUR WIRE SHOULD BE 18 TO 24 GAUGE, although any
wire that fits snugly in the strain relief fitting may be used.
Be sure to check the water-tightness of the fitting if you use
anything other than 18-24 gauge wire, as this may
compromise the integrity of the case. Put your two wires
under the terminal blocks, and fasten by screwing down.
Next, code your transmitter and, if necessary, your
receiver. The code switch (see figure 1) allows for 1024
possible combinations. If you have an existing receiver, you
may code the 3022 to the same code, or you may choose to
wire a separate receiver. If you wire a second receiver, be
sure to separate the two receivers as much as possible, to
avoid any possibility of interference.

If you are going to use the 3022 transmitter in a safety
related device, be sure to read the manufacturer’s
instructions with regard to wiring and limitations of the
safety circuit.
After you have wired and coded the 3022, you are now
ready for mounting. You will note that there are four holes
in the case, through which you can mount your screws,
rivets, or other mounting devices. If the transmitter is to be
used in the proximity of metal, be sure to test the location at
the greatest distance the device will be from its receiver, in
order to be sure that adequate performance is achieved.
ANY METAL, INCLUDING MOUNTING PLATES, ETC., MAY
AFFECT THE PERFORMANCE OF YOUR TRANSMITTER.
Once you are satisfied with the performance of the radio,
you can permanently mount it.
Linear Corporation has taken every precaution to
assure that the 3022 will perform reliably. In order to
provide the greatest reliability, we have fastened the
printed circuit board to the case with a special fastening
agent, such as Loctite. We suggest that you use a similar
material to your fastening screws if vibration is likely to be
encountered.
…IMPORTANT SAFETY TEST…
Before releasing the radio transmitter for use, test the system for
proper operation after installing the radio transmitter and
associated hardware. The system should be tested at various
positions of travel of the gate member to be certain that the gate
edge, radio transmitter, receiver and gate operator are
functioning to detect an obstruction and reverse or stop the
gate.
MAINTENANCE
The 3022 Transmitter needs a minimum of care,
however, certain precautions must be taken:
1. Be sure to check the 3022 Transmitter as a system. Be
sure that the device that is connected to the 3022 is
functioning with the transmitter, and with the
receiver.
2. Check the system to which the 3022 is attached fre-
quently.
3. The 3022 employs long life Alkaline-Manganese Dioxide
Batteries (Eveready Energizer 522 or equivalent). Nominal
life for these batteries is three years, but we suggest you
test the unit more often than this. Test the transmitter any
time you perform maintenance on the rest of the system.
