In-Floor Ramp Controller with Brass Adjustment Screws
1. Deploy Force Adjustment for Controller with Brass Adjustment Screws: For Deploy direction,
the maximum force attained by ramp against a forge-gauge before current limit shuts down,
is between 80 lbs. (33 kg.) and 100 lbs. (45 kg.). This will provide for the utmost in safety and
reliablity. Any force measureing instrument can be used as long as it contains a follower
needle to record maximum force attained. The set up must also contain a spring in series
with force measuring instrument to absorb ramp momemtum (elongation: 2 inches/5 cm.=80
lbs./33 kg.). To perform controller deploy force adjustment, follow this procedure:
A. Using a force-gauge, test ramp deploy force. If it is within 80-100 lbs. (33-45 kg.), do not
adjust. If adjustment is necessary, locate DEPLOY ADJUSTMENT SCREW.
B. With a small flathead screwdriver, turn adjustment screw no more than
5 turns counter-
clockwise (CCW)
to DECREASE force or no more than 5 turns
clockwise (CW)
to
INCREASE force.
C. Repeat above two steps. If reliable operation cannot be attained withing 80-100 lbs. (33-
45 kg.) of range, discontinue this procedure and check ramp for mechanical binding.
