WARNING
• TO REDUCE THE RISK OF PERSONAL INJURY OR DEATH, DO NOT CONNECT ELECTRICAL POWER UNTIL
COMPLETE OPERATOR, JUNCTION BOX AND CONTROL PANEL ARE INSTALLED, SECURED AND PROTECTED
PER FOLLOWING INSTRUCTIONS.
• ENSURE THAT AREA IS CLEAR OF PERSONNEL AND CORDONED OFF TO ACCESS WHILE INSTALLING
OPERATOR.
• USE PROPER SAFETY PROTOCOLS ACCORDING TO INTERNAL, LOCAL AND FEDERAL REQUIREMENTS.
MANDATORY FIRST STEP - Limit Bracket Installation
If your door is not already equipped with bumper/pusher springs, it is mandatory to install the supplied Limit
Brackets. Mount one bracket to the top of each track (See Figure 1A) to prevent over-travel of the door, and enable
automatic encoder recalibration prior to setting limits and after a power-loss. These should be mounted inside the
door-tracks at the door’s maximum allowable travel point, and are required to be located at the same exact position
on both tracks so that the top rollers of the door rest against them in a level position.
To install, manually open the door to the uppermost opening position allowable by the cables, clamp the door in
place, and secure the brackets to the track as shown Figure 1A using the top rollers as the reference points for the
brackets.
IN THE ABSENCE OF BUMPER/PUSHER SPRINGS, INSTALLATION OF LIMIT BRACKETS IS
MANDATORY PRIOR TO OPERATOR INSTALLATION. WITHOUT PHYSICAL LIMITS, THE DOOR CAN
RUN OUT OF ITS TRACKS AND CAUSE SEVERE PERSONAL INJURY AND/OR CAUSE SEVERE
DAMAGE TO THE DOOR. FURTHERMORE, YOU WILL BE UNABLE TO SET THE LIMITS.
MOUNTING INSTALLATION INSTRUCTION
Shaft Collar/Key Installation
The Shaft Collar serves as an end-stop for the gearbox on the shaft to prevent possible damage to the encoder magnet. It
is important that it is securely fastened prior to installation of the operator, and needs to be mounted in conjunction with the
key as shown in Fig: 5.
Adjust the door so that the shaft keyway is facing up (you may have to
open/wedge/clamp the door open slightly to achieve this).
Loosen the Shaft Collar set screw and slide it over the shaft
approximately 3 ½” from its end.
Insert the 3 inch long key (provided with operator) into the door shaft
keyway with one end flush to the end of the shaft.
Slide the collar back so that it touches the key, which should still be flush with the shaft end on its opposite side (the key
sits in the keyway between the collar and the end of the shaft), see Fig: 5.Firmly tighten the set screw of the collar onto
the shaft. Fasten the Torque Arm to the gearbox on the opposite side as the encoder, and at an appropriate position as
suggested on Drawing Figs: 4A-F)
Please note that in order to keep this collar as close to the door frame as possible and to accommodate
fastening of the torque arm, you may be required to cut the shaft to an appropriate length.
