6.2 Trouble Shooting and Repair Guide
( Refer all repair work to qualified technical service personnel! )
6.3 Motor Driver Adjustments
CURRENT ADJUSTMENT PROCEDURE:
The motor driver board has an overcurrent protection feature with adjustable threshold by RV1.
1.
Do not change speed setting unless a replacement board is installed. Otherwise, set the speed at factory default .
2.
Adjust ‘current’ carefully by observing red ‘overcurrent’ LED. The LED should blink for minimal duration each time the motor
starts. If the led blinks too long and brightly, turn adjustment left (CCW) for minimal flash duration.
Note:
If the speed setting is changed, ‘current’ must be re-adjusted.
Caution!
Panel may stall and retreat with no obstacle if RV1 setting is too low. In this case turn RV1 counter clockwise to reduce sensitivity.
If the setting is too high then panel may exert excessive pressure on an obstacle.
