IMPORTANT SAFETY INSTRUCTIONS

WARNING

TO REDUCE THE RISK OF SEVERE INJURY OR DEATH, READ AND FOLLOW ALL INSTRUCTIONS

1. Never allow children to operate or play with or near door.

2. Check to see that the operator is correct for the type, size of door and frequency of use per the

operator specifications.

3. If the door system is near a residential area, or pedestrian traffic is expected near the door system,

additional equipment such as electric reversing edges, photocells, or similar devices must be installed

as part of the system to prevent entrapment.

4. Reversing devices appropriate to the application must be installed as part of the system.

5. Outdoor or easily accessible controls must be of the security type to prevent unauthorized use of the

system.

6. Place controls far enough from the door so that a user cannot touch the door when operating the

controls.

7. Controls should be placed so the user has full view of the door when operating.

8. Always keep moving door in sight and away from people or vehicles until it is completely opened or

closed. NO ONE SHOULD CROSS THE PATH OF THE MOVING DOOR.

9. If a person is trapped under the door, push the "OPEN" control button.

10. Do not overtighten a clutch to compensate for a damaged door.

11. Test door and service monthly. After adjusting the limit travel, retest the door opener. Failure to adjust

the door may cause death or injury.

12. KEEP DOORS PROPERLY BALANCED. See door owner's manual. An improperly balanced door

could cause severe injury. Have a qualified service person make repairs to cables, spring assemblies

and other hardware.

13. If possible, use the emergency release only when the door is closed. Use caution when using this

release with the door open. Weak or broken springs may cause the door to fall rapidly, causing injury

or death.

and it is visible while the door is moving

4. INSTALLATION

All medium duty OPERA jackshaft operators are tested and adjusted at the factory. When installing your

unit, please note that the cams are resting in the center of the cam-shaft.

The OPERA operator has a dual output shaft and may be mounted on either the left or right hand side of

a sectional door (see Figure 2 and Figure 3). Place sprocket on either the right or the left end of the

output shaft according to the desired handing.

The Opera-MH comes with a chain hoist located on the right of the operator. If handing requires the

chain hoist to be on the left (rolling doors, left operator hood mounting for ex.), it must be requested at the

time of ordering. Do not attempt to change handing of the chain yourself.

4.1 IMPORTANT INSTALLATION INSTRUCTIONS

WARNING

TO REDUCE THE RISK OF SEVERE INJURY OR DEATH, READ AND FOLLOW ALL INSTALLATION

INSTRUCTIONS.

1. Installation of this door operator must be done by a qualified installer.

2. Insure that the door is properly installed and works freely in both directions. Do not install the

operator until all door problems have been corrected. If necessary, oil all moving parts (chains,

rollers, guides, etc.).

3. Remove all old accessories (locks, bolts, etc.) before installing door operator.

4. Do not connect the operator to a source of power until instructed to do so.

5. Locate control push-button station within sight of the door, at a minimum height of 5 ft. (1.5 m) so

small children cannot reach it, and away from all moving parts of the door.

4.2 INSTALLATION OF OPERA OPERATOR

IMPORTANT NOTE: THIS OPERATOR MUST BE INSTALLED A MINIMUM OF 8 FT. (2.4 m) ABOVE FLOOR.

The OPERA has two sets of mounting holes: outside the frame for wall mounting and inside the frame for

hood mounting.

To open the control box cover, loosen the screw at the base of the cover. If the cover cannot be fully

opened, the retaining arm may be used to hold the cover in other positions (Figure 4).

Figure 4 Control box cover opening

After installation, verify that there is no obstacle in the way when opening the control box cover. If so, it is

possible to remove the cover by unscrewing it from the box before putting the operator on the wall or

hood (see Figure 5).

Locate the four mounting holes. The optimum distance between the door shaft and operator drive shaft is

between 12" and 15". Mount the OPERA unit by fastening it to the wall, bench or hood with 3/8" or 1/2"

thru-bolts or if the wall is of such construction so as to prohibit use of thru-bolts, lag bolts and shields of

sufficient size may be used. Do not tighten.

CAUTION

MAKE CERTAIN THAT OPERATOR IS PERFECTLY ALIGNED WITH DOOR SHAFT OTHERWISE

DAMAGE CAN OCCUR

1. Place the driven sprocket on the door shaft loosely and align it with the drive sprocket of the

operator.

NOTE: If a chain spreader has been ordered along with your operator, see Figure 7 and Figure

8 below for installation.

Figure 7 Chain spreader Figure 8 Chain spreader mounted on door and

operator shafts

2. Lock the drive and driven sprockets in place by inserting the keys and tightening their respective set

screws.

3. Connect the sprockets with the drive chain, shorten to a suitable length and join together with the chain

link provided in the hardware bag. To shorten the chain, punch out the pin that will leave an inside link

nearest to the desired length. Connect the chain around the sprockets using the chain link (Figure 9).

Figure 9 Chain link

4. Slide the operator to tighten the drive chain and then firmly tighten the mounting bolts. Check the

tension on the chain and the set screws on the sprockets (there should be no more than 1/4" slack

when chain is depressed between sprockets

5. Opera-MH: run hand chain through the pocket wheel and through the chain guide outside the frame

(Figure 10A), allow both ends to hang down toward the ground and cut hand chain, if necessary, so

that both ends are approximately 2 feet (0.6 m) from floor. Connect both ends of hand chain.

6. Opera-MJ: link the disconnect chain at the key ring or hook located at the extremity of the disconnect

pull cable (Figure 10B) Place the Opera-MJ chain keeper so that, when pulled and engaged, the

disconnect chain keeps the machine ‘’disconnected’’ and in the manual position.

CAUTION

BEFORE PULLING HAND CHAIN THROUGH POCKET WHEEL OR LIFTING THE DOOR DIRECTLY BY HAND,

PULL CAM PLATE AND SPIN CAM NUTS TO CENTER OF LIMIT SHAFT SO AS TO BE SURE THE CAMS ARE

NOT BEING MECHANICALLY DRIVEN THROUGH THEIR NORMAL LIMIT SWITCH END POSITIONS.

4.3 LIMIT SWITCHES

WARNING

TO AVOID THE DANGER OF POSSIBLE DAMAGE TO THE DOOR AND OPERATOR, TRAVELLING

CAMS MUST BE ADJUSTED TO THEIR APPROXIMATE POSITIONS BEFORE MANUALLY

OPERATING THE DOOR OR BEFORE APPLYING POWER TO THE OPERATOR.

There are 4 limit switches. Two are used as end of travel, one is for radio-control or one-button

operation and one is for reversing devices. These switches are activated by the rotary cams travelling on

a threaded shaft (Figure 11).

ADJUSTMENT OF LIMIT SWITCHES

WARNING

NEVER PLACE HANDS OR TOOLS INSIDE OPERATOR OR NEAR DRIVE MECHANISM UNLESS

POWER IS OFF.

1. Open the cover of the electrical enclosure.

2. Manually raise the door to a nearly opened position (see section 4.9)

3. Pull the travelling cam retaining bracket on the Open Position cam side and rotate the Open Position

cam (Figure 12).

Note: Turning the cam towards the center of the shaft increases door travel.

Turning the cam towards the switch decreases door travel.

4. Manually rotate the Open Position cam until the lever activates the Open limit switch sufficiently so

as to hear the switch click.

5. Release and engage the retaining bracket. Make sure that the bracket engages in the slots of both

limit cams after each adjustment.

6. Manually lower the door to a nearly closed position and repeat steps 3 through 5 with the Close

Position cam.

7. Upon completion of all wiring connections (section 4.5 and 4.6, repeat steps 2 through 6 using the

"Stop" button for adjustments of limit switches to their final, exact positions.
