GENERAL INSTALLATION NOTES
Preparing Door for Opener
The following procedures must be performed before opener can be installed. Failure to com-
plete the following procedures can cause opener failure and/or hazardous conditions which
could cause personal injury.
1. Check working condition of door. Door should operate freely without sticking or bind-
ing, and should not have to be held up or down. Lubricate door rollers and hinges with
SAE 30 wt • oiI•
2. If any part of the door is worn or broken, call a qualified door service person to repair
it before the opener is installed.
WARNING
Door is under extreme spring tension. Repairs and adjustments, especially to
cables and spring assembly, can be hazardous and can result in severe personal
injury. Repairs and adjustments should be performed only by qualified door
service people.
3. If door is equipped with a locking device, make it inoperative by permanently securing
the locking bar in an unlocked position.

TRANSMITTER
General Information
If you have two transmitters and one does not work it is reasonable to
assume the problem is in the transmitter. However, when you have
one transmitter and it does not work, the problem may be in the
receiver. When returning controls to the factory for service, it is
always recommended that you send the receiver ond all transmitters
so they can be serviced and tested as a set.
When writing to the factory for assistance or when returning a control
for repair be sure to include the following information;
1. RADIO CONTROL MODEL NO.
2. NUMBER OF TRANSMITTERS
3. DOOR OPENER MODEL NO,
AND MANUFACTURER'S NAME
4. DATE UNIT WAS INSTALLED
5. NATURE OF DIFFICULTY
See Page 19 for address.
For maximum Radio Control performance on garages with two or more openers,
it is recommended that the Radio Frequency(RF) of each unit be different. For
example: 380 --- RF on one opener with 360 --- on the second opener.
(Refer to sticker on back of transmitter).
Your Radio Control System
Your Tri nary Digital Control is designed to give years of
trouble-free service. The concept of Digital Control allows
you to easily
change the coding of your control, should you
experience "phantom" operation. Phantom operation is the
inadvertent opening or closing of your garage door by on out-
side signal source other than your own hand-held transmitter.
Should you experience this inadvertent operation, follow these
simple steps to
change the coding of your tronsmitter(s) and
receiver. We recommend you do not change the coding UNLESS
you ore
experiencing "phantom" operation,
How To Change Radio Coding
1• Open transmitter access door as
shown in Figure 1. BATTERY

FIGURE 2
How To Change Radio Coding
3. To change the code (see Fig. 2), simply change
the position of one or more of the code switches on the Receiver
and Transmitter(s) circuit board, PLEASE NOTE: The code
switches (three position) settings of the Receiver and T rons-
mitter(s) must match each other. EXAMPLE: If code switch
No. I is "+" in the Receiver, code switch No. 1 must be "+"
in the Transmitter(s), and so on.
4. If you hove purchased only one Transmitter and you wish to
purchase a second
one, specify the frequency and code found on the
white sticker an the back of the Transmitter or Receiver case.
EXAMPLE:
FREQ 360-BBC .. -----1 Specify frequency number
MFG. 880915 and letters when ordering
a second
transmitter.
When you receive the new transmitter it will NOT work with your
present Digital receiver if you have previously changed the code
switches in the receiver. You MUST position the new transmitter code
switches to the same"+", "O", "-"sequence as your receiver code
switches. Refer to Item 3 above.
5. Replace Code Access door on Transmitter.
NOTE:---------------.
Warranty on the Control will be nullified if service other
than specified in the service hints is not performed at the
factory.

Adjustment and Testing of the ReversinH System
l\fM;Hll: el
The proper adjustment and testing of the Reversing System is important for the
safety of everyone who uses your door and opener. Failure to properly adjust
and test may result in serious personal injury from a closing garage door. The
(e)
(©)
MIN MAX
l'M

MAX
FIGURE 3
System consists of an electronic device that senses motor slowdown due to increased load.
The Reversing System is a safety feature that reverses the door's travel and
returns it to the fully open position if the door encounters an obstruction or resistance
while closing. If this does not happen and the door cannot close completely, an additional back-up
circuit will automatically reverse the motor within 30 sec. and fully open the door.
The reversing system is designed to operate in the closing direction after the motor has run one secon i,
and until the door is closed completely.
The sensitivity of the reversing mechanism is controlled by the sensitivity adjusting shaft(See Fig. 3) .
The
end of the shaft is marked to serve as a position indicator and can be rotated thru 3/4 turn betw Ee n
maximum
and minimum sensitivity. Turning the shaft clockwise increases the sensitivity so as to requ ir e
less
resistance to reverse the door. The reversing system should be set for maximum sensitivity (indic ~ t or
in green area of arrow or possibly yellow area) consistent with proper operation of the door. Do not
decrease the sensitivity to compensate for a binding or sticking door (indicator in red area). If setti rg
must be in red
area, check door operation manually (See Item 9, Page 17).
As a final check, place a 1- 1/2" thick board on the floor in the path of the door. When the door
strikes this board it should reverse within 2 seconds and fully open. If it does not, check the door
opener linkage, . and opener for proper adjustment and operation .
For your
safety, it is vital that the reversing mechanism be adjusted to perform properly. Check it
every six months or call a 1i professional door service person to check it for you. If, for any reason, the
opener is not functioning properly, immediately disconnect the opener from the door (Emergency
Release
Operation) and do not reconnect until the problem is corrected.
Adjusting "Up" Sensitivity
The "Up" sensitivity adjustment shaft is located beside the reversing sensitivity ("Down") adjustme nt.
If the door encounters an overload while opening, the opener will stop only. Turning the "Up"
sensitivity knob counter - clockwise wil I increase the amount of force necessary to stop the door's
upward movement if it encounters an obstruction. Turning the shaft clockwise will decrease the force
required to stop the door. Adjustment should be made just to the point that wirl allow the door to fu lly open.
l\2~n:11:u1
If satisfactory operation of the door/opener cannot be achieved by following the instructions obo Vif3 ,
disconnect ' the opener from the door by pulling the emergency release rope (page 17), then check
operation of the door alone. If door balance, rollers, and hinges operate smoothly, without striki rll g
or binding in the jambs, reconnect the opener and repeat the sensitivity adjustment procedure. If
door/opener operation is still unsatisfactory, contact qualified door service personnel .

substitute with any ether voltage input.
8. Opener motor is protected against burn-out by an internal
protector which wi II stop motor if door is opened and closed
loo many times in succession, or if some other overload con-
dition exists. If motor stops, allow it to cool 10-15 minutes,
then press wall push button to resume operation.
9. It is suggested that every 6 months door be disconnected from
opener and manually operated. Door should open and close
freely. If door does not operate freely, correct the problem.
Door is under extreme spring tension. Repairs and
adjustments, especially to cables and spring assem-
bly, con be hazardous and con result in severe per -
sonol
injury. Repairs and adjustments should be
performed
ONLY by QUALIFIED DOOR SERVICE
PEOPLE.
to, For normal conditions, lubrication of opener rotating and sliding
parts is not required. Motor is permanently lubricated.
II. DO NOT lubricate boom. It is possible a film may develop
inside the nylon carriage. This film may cause binding in
freezing weather. To correct, spray boom, or either side of
carriage, with a spray lubricant (WD 40, LIQUID WRENCH,
etc.), run opener open and closed, then wipe boom clean.
TROUBLESHOOTING GUIDE
This troubleshooting guide shows malfunction symptoms and their possible causes. Use it to help
