11.2 Push Arm Installation Steps
11.2.1 Attach Drive Arm to Operator
Caution: Door must be fully closed! Caution: ED operator axle closed position. In order to mount the drive arm in the correct position, the axle must be at the closed position.
Warning Use caution when working in proximity of door and push arm!
- Set ED50/ED100/ED250 operator spring tension based on width of door (See Chapter 12).
- Insert axle extension into drive arm.
- Move arm to ED50/ED100/ED250, inserting arm into axle extension sleeve at a 90° angle to operator.
- Thread SHCS into ED50/ED100/ED250 spindle and tighten.
Caution Use torque wrench with hex key socket to tighten SHCS to 26 ft-lb [35.3 Nm].
11.2.2 Drill Holes in Door for Adjustment Arm Shoe
Installation templates (Chapter 7) document location of shoe on door.
- Drill two holes in door for adjustment arm shoe. Fastener type depends on door material.
Tips and Recommendations Reference Chapter 2 for arm fasteners.
11.2.3 Secure Adjustment Arm Assembly to Door
- Fasten adjustment arm assembly to door (Fig. 11.2.6).
11.2.5 Connect Adjustment Arm to Drive Arm
- Loosen the two adjustment M6 x 10 mm flanged button head screws.
- Using a square, position adjustment arm assembly at a 90° angle to the door.
- Rotate drive arm and adjust length of adjustment arm until drive arm ball head (8) is aligned with adjustment arm socket (2).
- Insert adjustment arm ball head (8) into drive arm socket (2). The spring in the socket will retain the ball head.
- Secure adjustment arm position by tightening the two M6 x 10 mm flanged button head screws.
Caution Maintain adjustment arm assembly at a 90° angle to door. Recheck after tightening.
11.2.4 Install Shoe Fastener Covers
- Install two shoe fastener covers (11).
Chapter 12: ED50/ED100/ED250 Operator Spring Tension
12.1.1 Spring Tension Setting Revolutions
Use the table below to determine the required spring tension revolutions based on door width.
| Door Width (Inches) | 28" | 32" | 36" | 42" | 48" |
|---|---|---|---|---|---|
| Door Width (mm) | 711 | 813 | 914 | 1067 | 1219 |
| ED50 | 10 | 10 | 14 | 16 | 18 |
| ED100 | 10 | 10 | 14 | 16 | 18 |
| ED250 | 10 | 10 | 14 | 16 | 18 |
12.1.3 Spring Tension Adjustment
Spring tension adjustment is factory set fully CCW (no spring tension). It must be pre-tensioned before operation.
- Use a 5 mm T-handle hex key.
- Clockwise: Increases spring tension.
- Counterclockwise: Decreases spring tension.
Caution A minimum of ten (10) spring tension revolutions are required to operate the system.
12.1.4 Check Door Closing Force
- Use a pressure gauge to check door closing force at 2°.
- Adjust tension setting if necessary.
Tips and Recommendations System checks spring tension during learning cycle. Learning cycle will be canceled if spring is insufficiently tensioned. Door will stop and display will show a rotating "0" and an "F".
