PULL BACK RIGGING OPERATING INSTRUCTIONS
5
Movement
To transition from
top grid
to
pull back
:
1. Use the top grid motors to raise the array to trim height.
2. Slack the front motor until achieving the maximum natural downward tilt.
Make sure there is enough slack in the
top front of array motor(s)
to allow the added rotation introduced by the pull back.
3. Pick up the slack of the pull back motor until it is under tension.
4. Without exceeding the rated pull back load, take the pull back motor up to the desired downward tilt angle.
NOTE:
Make sure the downward tilt angle does not exceed the simulated configuration in MAPP XT. This may
result in an unstable array or exceed the maximum rated pull back load.
5. Pick up the slack of the
top front of array motor points
.
Do not use the
top front of array motors
to pick up the top grid, change the trim height, or change the angle as that will
alter the MAPP XT calculated loads.
NOTE:
Removing the slack is only to ensure that any failure of the
top rear of array motor
will result in the load
being picked up by the
top front of array motor points
.
