PULL BACK RIGGING OPERATING INSTRUCTIONS
6
Load
1. Engage both top grid motors to take the complete load of the array.
2. When at trim height (top rear of array motor point reference), the load is fully transitioned to the top rear of array motor
point(s).
3. Total array load is distributed between the top rear of array motor point(s) and the pull back rigging point.
4. The pull back rigging motor point load increases until it reaches the desired array downward tilt angle.
5. The top front of array motor point(s) should be tensioned with minimal load to avoid rattling and provide an extra safety
rigging point.
NOTE: Changing the top of array pickup point from the rear to the front increases the pull back rigging motor point
load and reduces array stability.
