Important safety test – Linear 1051 User Manual

Page 2

If you are going to use the 1051 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 1051, 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 1051 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 1051 Transmitter needs a minimum of care,

however, certain precautions must be taken:

1. Be sure to check the 1051 Transmitter as a system. Be

sure that the device that is connected to the 1051 is
f u nc t i on i ng w it h t h e t r a n s m i t t e r , a n d w i t h t h e
receiver.

2. Check the system to which the 1051 is attached fre-

quently.

3. The 1051 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.
