SITE PREPARATIONS

It is imperative that the wall or mounting surface pro-

vide adequate support for the operator.

This surface must:

a) Be rigid to prevent play between operator and

door shaft.

b) Provide a level base.

c) Permit the operator to be fastened securely and

with the drive shaft parallel to the door shaft.

The safety and wear of the operator will be adversely

affected if any of the above requirements are not met.

Both J and H series operators have dual output

shafts and may be mounted on either the right (stan-

dard) or left side of door, and in either a vertical

(standard) or horizontal mounting position. If you

need to move the drive sprocket, loosen BOTH set

screws, remove the sprocket and key, and place on

the opposite side of the drive shaft. Be sure to tight-

en BOTH set screws securely

On all models with B2 control wiring, a terminal bracket

marked R1 R2 R3 is located on the outside of the electri-

cal enclosure. Any commercial type LiftMaster brand

receiver may be mounted to this bracket. The operator

will then open a fully closed door, close a fully open

door, stop an opening door, and reverse a closing door

from the radio transmitter. In TS control wiring the oper-

ator will only open the door or reset the timer to close.

However, for additional door control from a 3 button

transmitter, a commercial three-channel radio receiver

(with connections for OPEN/CLOSE/STOP) is recom-

mended.

2. Be sure to run all control wires through the conduit

hole in the electrical box enclosure marked with the label

shown below.

3. Apply power to the operator. Press OPEN push button

and observe direction of door travel and then Press the

STOP button.

If door did not move in the correct direction, check for

improper wiring at the control station or between operator

and control station.

BRAKE ADJUSTMENT

A solenoid brake is optional on all models, and is optional on 1/3 and 1/2 horsepower models. The brake is adjust-

ed at the factory and should not need additional adjustment for the the life of the friction pad.

Replace friction pads when necessary. Refer to the

illustration for identification of components for the

solenoid type brake system.

CLUTCH ADJUSTMENT AND AUXILIARY REVERSAL SYSTEM

1. Remove cotterpin from nut on the clutch shaft.

2. Back off clutch nut until there is very little tension

on the clutch spring.

3. Tighten clutch nut gradually until there is just

enough tension to permit the operator to move the

door smoothly but to allow the clutch to slip if the door

is obstructed. When the clutch is properly adjusted, it

should generally be possible to stop the door by hand

during travel.

4. Reinstall Cotterpin.

The Auxiliary Reversal System works in tandem

with the adjustable clutch to detect if a closing door

meets an obstruction. If an obstruction is met and

causes the clutch to slip, the Auxiliary Reversal

System will return the door to the full open position.

The Auxiliary Reversal System is designed to protect

the door and motorized operator. It is not intended as

a replacement for a safety sensing device, nor will it

work for sectional doors when a jackshaft operator is

used.
