IMPORTANT SAFETY NOTES

The force, as measured on the closing edge of
the door, should not exceed 150 N (15kg). If the
closing force is adjusted to more than 150 N,
additional entrapment protection devices must
be installed, see page #9 for matrix. Do not use
the force adjustments to compensate for a bind­ing or sticking door. Excessive force will interfere

with the proper operation of the Safety Reverse
System or damage the door.

Fasten the caution label adjacent to the door con-
trol station as a reminder of safe operating proce­dures.

Disengage all existing door locks to avoid damage
to door. If the door lock needs to remain functional,
install an interlock switch.

Install the three button station, master discon­nect switch and any additional controls in a
location where the door is visible, but out of the
reach of children. Do not allow children to oper­ate push button(s) or remote control(s). Serious

personal injury from a closing door may result from
misuse of the opener.

CAUTION: Activate opener only when the door
is in full view, free of obstructions and opener is
properly adjusted. No one should enter or exit
through the door opening while the door is in
motion. Do not allow children to play near the
door.

Proper electrical lock-out/tag-out procedures
must be followed before making repairs or
removing covers on the door operator.

Keep door balanced. Sticking or binding doors

must be repaired. Doors, door springs, cables, pul­leys, brackets and hardware are under extreme ten­sion and can cause serious personal injury. Do not
attempt to loosen, move or adjust them. Call for
door service.

Proper protective gear should be worn when servic­ing or installing the door operator. Do not wear
rings, watches or loose clothing while installing or
servicing a door opener. Do wear safety glasses,
back support belt, and protective gloves. When
working on ladders and or elevated platforms, prop­er safety procedures must be followed.

To avoid serious personal injury from entanglement,

remove all ropes & chains connected to the
door before installing the door opener.

SITE PREPARATIONS

It is imperative that the wall or mounting surface pro­vide 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,

with the drive shaft parallel to the door shaft.

The safety and life of the operator will be adversely
affected if any of the above requirements are not met.

For metal buildings, fasten 50mm x 50mm x 5mm (2”
x 2” x 3/16”) (or larger) angle iron frames to the build­ing purlins. Retain 140mm (5-1/2”) between frames.
See Figure 3.

Both EJ and EH series operators have dual output
shafts and may be mounted on either the right (stan­dard) 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 tighten BOTH
set screws securely

Hand Chain Handing

For model EH with manual hoist hand chain systems,
the handing of the operator must be determined at the
time of order. The handing is indicated by last letter of
the model name (R or L). The hand chain wheel can
not be switched on site. If your installation causes
the hand chain to hang in the door opening, hook the
chain off to the side near the top of the door jamb.

OPERATOR PREPARATION

140mm

(5-1/2”)

Door Requirements: Door must be balanced within 150N and must have mechanical fixed stops at the end

points of travel

The weight of this operator powerhead is excessive, and can cause severe injury upon lifting, installing
or dislodging from its mounted position.

The operator powerhead should be raised into its mounting position by use of a hoist or elevated plat­form. Acceptable lifting points are output shaft or chassis frame. Do not lift by electrical enclosure. The
unit should be secured to the lifting apparatus to prevent it from swaying or dislodging during installa­tion. The unit should be fastened to its mounting surface with the correct size and grade hardware. All
mounting hardware should be securely fastened before releasing supporting devices. (See figure 4 on
page 6 for proper lifting).

The above stated procedures must be followed in the event that the unit is to be removed from
its mounted position when servicing is required.

and operator drive shaft is between 305-380mm
(12 - 15”). Refer to Figure 5.

OPERATOR MOUNTING

IMPORTANT:

The shelf or bracket must provide ade­quate support, prevent play between operator and door
shaft, and permit operator to be fastened securely, with
the drive shaft parallel to the door shaft.

1b. Bracket or Shelf Mounting

The operator may be mounted either above or
below the door shaft. The optimum distance
between the door shaft and operator drive shaft is
between 305-380mm (12 - 15”).

Refer to Figure 6.

1c. Place door sprocket on the door shaft. Do not

insert the key at this time.

2. Place drive sprocket on the appropriate side of the
operator. Do not insert the key at this time.

3. Wrap drive chain around door sprocket and join
roller chain ends together with master link.

4. Raise operator to approximate mounting position
and position chain over operator sprocket.

5. Raise or lower operator until the chain is taut (not
tight). Make sure the operator output shaft is par­allel to door shaft and sprockets are aligned. When
in position, secure the operator to wall or mounting
bracket.

6. Align sprockets and tighten all set screws and
mounting hardware. (see Figure 7).

These operators are equipped with a manual hoist. An
electrical interlock will disable the electrical controls
when the hoist is used. To operate the hoist:

1. Pull the disconnect chain (small chain) to engage the
hoist mechanism. The disconnect chain may be locked
in position by slipping the end through the keyhole of
the chain keeper mounted on the wall.

2. Operate the door in the desired direction by pulling
on one side or the other of the continuous loop hoist
chain (large chain).

3. The disconnect chain must be released from the
chain keeper before the door will operate again electri­cally.

7. Install Hand Chain (Model EH) Place hand
chain around hand chain wheel. Be sure to pass
it through both openings in the chain guide.
Remove enough links so chain hangs approxi­mately 609mm (24”) above the floor.

EMERGENCY MANUAL OPERATION

This operator has provisions for manually operating the door in case of an emergency or power failure. Refer to
the appropriate instructions below for your model operator.

Model EH

Model EJ

This operator has a floor level disconnect chain to dis­connect the door from the door operator. An electrical
interlock will disable the electrical controls when the
operator is disengaged.

1. To disengage, pull the chain and secure in the dis-

engaged position by slipping the end through the key­hole bracket mounted on the wall. Or if emergency
egress device is used, pull handle to disengage oper­ator from door.

2. The door may now be pushed up or pulled down

manually. Release the disconnect chain to operate the
door again electrically.

TO AVOID SERIOUS PERSONAL INJURY OR DEATH
FROM ELECTROCUTION, DISCONNECT ELECTRIC
POWER BEFORE MANUALLY MOVING LIMIT NUTS.

WARNING

MAKE SURE THE LIMIT NUTS ARE POSITIONED BETWEEN THE LIMIT SWITCH ACTUATORS BEFORE
PROCEEDING WITH ADJUSTMENTS. (Limit switch adjustments are located on the front wall of the elec­trical enclosure, see figure below)

1. To adjust limit nuts depress retaining plate to allow
nut to spin freely. After adjustment, release plate
and ensure it seats fully in slots of both nuts.

2. To increase door travel, spin nut away from actu-
ator. To decrease door travel, spin limit nut toward
actuator.

3. Adjust open limit nut so that door will stop in open
position with the bottom of the door even with top
of door opening.

4. Repeat Steps 1 and 2 for close cycle. Adjust close
limit nut so that actuator is engaged as door fully
seats at the floor.

Alert LED

Programmable Mid-stop:

The system will learn a programmable Mid-Stop point and will stop at that point when­ever the door is opened from a fully closed position.

Setting Mid-Stop:

Start with the door in the fully closed position. Set DIP switches to “set mid-stop”
mode. Press the open button. When the door reaches the desired Mid point, press
the stop button. Set DIP switches to the desired operating mode (B2, C2, T, TS,
FSTS). Press the open button and allow the door to run to the open limit.

Clearing Mid-Stop:

Start with the door in the fully closed position. Set DIP switches to “set mid-stop”
mode. Press the open button. Allow the door to run to the open limit. Set DIP switch­es to the desired operating mode (B2, C2, T, TS, FSTS).

Programmable Maximum Run Timer:

Any time a “closing” or “opening” door takes 10 seconds longer than its programmed
normal cycle time, the door will stop. The factory default for maximum run time is 90
seconds.

Setting Maximum Run Timer:

Start with the door in the fully closed position. Set DIP switches to “set max run timer”
mode. Press the open button. Allow the door to run to the open limit. Once the door
has stopped, set DIP switches to the desired operating mode (B2,C2, D1, E2, T, TS,
FSTS). The maximum run time is now set to the door’s travel time + 10 seconds.

Maintenance Alert System

Set dip switch to set cycle counter mode. When the operator is in this mode the LED
will flash the number of times in 5k increments the operator has cycled followed by a
five second delay.

(Refer to figure 1 for LED location on the pushbutton).
