CALIBRATION
Center Potentiometer and Set Positions
1. Enter “Position Config” submenu.
2. Verify “Position Type” is set to
“Potent”.
3. Enter “Calibrate Close Pos”.
4. Manually operate actuator to 50%
position using joystick [PREVIOUS]
and [NEXT] or using actuator
manual override.
5. Adjust feedback potentiometer until
value reads between 1900-2200,
then tighten potentiometer gears.
6. Operate actuator to CW position and
press [CONFIRM] to save position.
7. Enter “Calibrate Open Pos”.
8. Operate actuator to CCW position
and press [CONFIRM] to save
position.
Approximate potentiometer ranges with potentiometer centered exactly to 2048 at
50% position. Specific values are not as important as ensuring value does not
jump between 0 and 4095 inside of operation range.

Problem
Resolution
No Display  In Sleep Mode. Press joystick in any direction to wake.
 Ensure Run/Program switch is pointed away from USB connector.

Ensure
supply power
present
or fuse is
not
blown.
Not Moving to set
positions
 Check
mechanical stops, or limits switches are not adjusted in too far.

Ensure potentiometer gears are not loose. Recalibrate if so.
Movement in wrong
direction

Open and Close positions set incorrectly, or Zero and Span reversed.

Motor CW / CCW wiring
reversed.
Problem
Resolution
Not responding
to command
signal
 Check command signal and position calibration.
 Ensure feedback potentiometer is centered, gears are not
loose.
Recalibrate if so.
No feedback or
feedback
incorrect
 Check feedback calibration.
 Ensure no external loop power is provided.
