12. OPERATION OF YOUR OPERATOR (cont’d)
OPERATOR LIGHTS:
The amount of time that the operator light(s) are “on” can be
adjusted. Please refer to level 5 menu 4 in the “Advanced Settings”
Lights will come on whenever operator is activated. The default
factory setting for the light to stay “on” is 4 minutes and 15 sec., or
until the Light On / Off button on the wall control panel is pressed,
whichever is sooner.
Lights can be turned on and off manually as described under
operation of wall control panel.
Lights will flash when the operator senses an obstruction either detected
by the internal safety system or the photo eye sensors. To stop lights
from flashing, remove obstruction and operate door normally. The fault
light indicator will flash for the set light time “on” or for the factory
default setting of 4 minutes and 15 seconds maximum.

17. TENSION ADJUSTMENT
Your preassembled rail comes with the tension adjusted to factory
specifications. There should be no need for further adjustment. However,
if exposed or subjected to unusually harsh operating conditions, the
tension may need to be readjusted during the life of the operator.
Check Proper Tension:
Release trolley from belt connector, then examine the setting of
the tension adjustment at the header end of the rail.
Proper tension is set when the tension nut is tightened just
enough so that the washer will be spaced approximately 21mm or
13/16" from the rail end-plate. See Fig. 51.
If the gap between the washer and the rail end-plate is too big or
too small, the tension needs to be adjusted.
Adjust the Tension:
To increase the tension and tighten the belt, turn the
tension nut clockwise with 1/2” or adjustable wrench until the
washer is spaced properly from the rail end-plate. See Fig. 51.
Once the washer is spaced correctly, any additional tightening
will overtighten the belt and may cause damage to the system.
To loosen the tension, turn nut counterclockwise.
Reattach trolley.

8-1. ATTACH RAIL TO OPERATOR HEAD
Position door operator head with control panel facing front of
garage. Rest operator head on cardboard or protective surface
on floor so operator does not get scratched. Chassis side of
operator (with motor shaft sticking out) facing up.
Position rail onto operator chassis by lining up rail sprocket
opening with motor head shaft (Fig. 7A). Make sure shaft
engages teeth inside rail sprocket. Press rail down firmly onto
shaft and operator chassis. DO NOT HAMMER.
Position 2 "C" brackets over rail and onto chassis. Flanges on
"C" brackets MUST fit into cutout area on chassis (Fig. 7B).
Insert screws (6 x 14) through bracket holes and into chassis
holes, and tighten screws firmly to hold rail to head (Fig. 7C).
8. INSTALLATION STEPS
Unpack operator and one-piece preassembled rail and prepare
hardware components for installation. Identify a sound structural
support on header wall above garage door for header bracket
mounting. See Fig. 8. If appropriate header does not exist, replace
or install a new support using a 2x4 or 2x6 board. Fasten it securely
using lag screws (not provided) to structural supports of garage.

8-2. MEASURE AND MARK DOOR AREA
Before starting your installation, the door and the header above
the door must be measured and marked. This way, the
appropriate brackets can be mounted at the correct locations
avoiding installation and operating difficulties later.
MARK VERTICAL CENTER LINE:
Measure door width, then locate the center point (Fig.8).
Mark a vertical line on the upper half of your door, on the top
edge of your door, and on the header, through the center
point.
MEASURE DOOR’S HIGHEST TRAVEL POINT:
Open door to its highest travel point and measure from the
garage floor to the top of door (Fig.9).
Write down this distance.
Add 1-1/2” to the door travel height (measured above).
MARK HORIZONTAL LINE FOR HEADER BRACKET
LOCATION:
Close door and measure the required distance (determined
above) from the garage floor to the header.
Mark a horizontal line, intersecting the vertical center line, on
header. This is the position at which the bottom of the header
bracket should be installed.
In case of minimal clearance above the door, the header
bracket may be mounted to the ceiling. In this case, extend
the vertical center line onto the ceiling, and mark a horizontal
line on the ceiling no further than 4" from the header wall.
The header bracket should be mounted no farther than this
distance from the header wall.
When fastening the rail to the operator,
use only the screws provided. Use of any
other screws may result in operator falling
from ceiling and causing damage
to persons or property in the garage.

13. MODULAR ANTENNA
To replace modular antenna simply pull out existing module located on
the top of the chassis, and slide in the new one. It will make a clicking
sound when the receiver module is locked into place. (See Fig. 48)
14. LOCMATIC READY
The control module harness on the same side as the operator power
cord shown on figure 48A is provided for connectivity with the
Locmatic System control module.
The Locmatic door lock system is an optional accessory sold
separately.
