1. AS parameter-Installation type, Para. 31.7
2. Tb parameter-Door width, Para. 31.2
3. Braking circuit plug, Para. 31.1
4. Spring tension, Para. 31.4
Step 1
Block arm at door closed position.
Hold block in place [Use caution!], or

Display indicates arm is at 70° position.
Reference Fig. 31.9.3 and 31.9.4.
Step 4
If desired, manually move door to 900
position for door installation.
TIPS AND RECOMMENDATIONS
• Arm installation; Reference Chapter 28.
• Arm must be blocked at door closed position
(0 degrees) during the learning cycle so that
it cannot travel past this position in the door
closing direction.
• Partial learning cycle will position arm at
70 degree position for door installation.
31.9.1 Initiate learning cycle to rotate arm.
Operator spring tension too low.
• Display with small rotating "o" and
an "F" during learn cycle indicates
spring tension is too low.
• Arm rotates to closed position.
1. Increase spring tension (Para. 31.4).
2. Restart learning cycle (Step 2).
