Figure 2 Standard Force Standard Force Increased Force Increased Force 4a The door opening speed must be adjusted to suit the width and weight of door. The wider and/or heavier the door, the slower it should open. To determine opening speed, measure door leaf width and weight and set speed to open door from 0° to 80° for the time shown in Table 3 on page 3. The opening speed control adjusting screw is located in the end of the door operator near the tubing connection (see figure 1). Using a 3/32” allen wrench (provided), turn the speed control clockwise to slow the door, counter clockwise to increase speed. Door Weight in Pounds 100 lbs. 125 lbs. 150 lbs. 200 lbs. FASTEST OPENINGTIME 0° to 80° DOOR WIDTH IN INCHES 36" 42” 48” 3.0 sec 3.5 sec 4.0 sec 3.5 sec 4.0 sec 4.5 sec 3.5 sec 4.0 sec 4.5 sec 4.0 sec 4.5 sec 5.5 sec Table 3 LL NOTE: If door width or weight is between the sizes and pounds listed, use the time shown for the next wider or heavier door. Caution DO NOT SET DOOR SPEED FASTER THAN CHART RECOMMENDS 4b If door weight cannot be measured, the weight can be estimated by finding the area of the door (length x width) and multiplying it by the weight per square feet for the door type that is being used as shown in Table 4 below. Type of Door - Solid Core Wood Weight per Sq. Ft. 5.5 lbs - 20 Ga.Flush Hollow Metal - Aluminum x 1/4” Glass - Mineral Core Door 7.0 lbs - 16 Ga.Flush Hollow Metal - Aluminum x 1” Glass Table 4 LL NOTE: These weights are for 1 3/4” thick doors. If the doors are thicker or thinner, consult door manufacture for proper weight or weigh the door. 5 Backcheck Adjustment 5a Backcheck slows the door swing as it approached full opening (see figure 1 on page 2). 5b Increase the resistance of backcheck only if necessary to prevent the door from striking a wall. To do this, turn the regulating screw (nearest to hinge) clockwise by quarter turns. DO NOT USE AN ABRUPT BACKCHECK. 6 Delay Time Adjustment After opening, the door should remain at the 90° position for no less than 5 seconds. This “Delay Time” can be increased to approximately 30 seconds by turning the timer adjustment wheel(s) clockwise. For the location of this wheel(s), refer to 7900 or 7980 Series Control Box Instruction Sheet. Adjust “Delay Time” to maximum practical for the elderly or handicap. Time cycle begins when switch or scanner is released. 7 Attach Cover 7a Slide cover insert into the top cutout in cover (see figure 4). 7b Push cover over the operator assembly and against mounting plate. 7c Insert cover screws and tighten securely. 8 8a Locating The Caution/Automatic Door Decal 9 Local one decal on each side of the door near lock stile of door, approximately 18” min. to 42” max. above the floor. The decal location must be visible without interference from door trim, panic devices, etc. It may be necessary to adjust the fully open door position. Minor adjustment can be obtained by using the telescoping arm as follows (see figure 5): 8b Clean area 6” x 6” where decals will be placed. 8c Apply one decal (item 17 on page 5) on each side of door. Remove backing and “roll” onto door to avoid trapping air under decal. Double Lever Arm Set Screw Adjustment AUTOMATIC 9a Shorten length of arm to decrease door opening. Lengthen arm to increase door opening. 9b Loosen arm set screw and adjust arm to preferred length. 9c Tighten arm set screw securely after adjustment. 9d After arm adjustment is made, cycle door to insure that it is operating properly.
