Rapid-Air DUAL SWIVEL REEL: 100 & 1000 SERIES - Manual (Page 14)

The following procedure, presented in order of adjustment sequence, should be used
when readjusting all trimpot functions.
Fig. 2 ACCEL/DECEL TRIMPOT ADJUSTMENT
A. Acceleration Start. The ACCEL is factory set at approximately .2 seconds. To re-
adjust to different times, set the knob to the desired position as indicated in fig. 2.
B. Deceleration. The DECEL is factory set to provide a ramp down time of .2 sec-
onds. To change the ramp-down time, adjust the DECEL trimpot as indicated in fig.
2.
C. Minimum Speed Adjustment. If a higher than zero minimum speed is desired, read-
just the minimum speed by turning the speed control knob to zero setting (full CCW
position). Then adjust the min. speed trimpot to the desired setting.
NOTE: The min. speed adjustment will affect the max. speed setting. Therefore, it is
necessary to readjust the max. speed after the min. speed is adjusted.
D. Maximum Speed Adjustment. Turn speed control knob to full speed (maximum CW
position). Adjust max speed trimpot to new desired setting.
NOTE: Do not attempt to adjust the max. speed above the rated motor RPM since un-
stable motor operation may occur. For moderate changes in the max. speed, there will
be a slight effect on the min. speed setting.
E. Current Limit (CL Torque Adjustment) CL circuitry is provided to protect the motor
and control against overloads. The CL also limits the in rush current to safe level
during startup. The CL is factory set to approximately 1.5 times the full load range
of the motor. (CL trimpot is nominally set to approximately 65% of full CW rotation).
To set the CL to factory specification adjust as follows:
1. Set speed control knob to approximately 30-50% CW rotation.
Set CL trimpot for full CCW position.
2. Connect a DC ammeter in series with the armature lead.
