DIP 3

DIP 4
Sets direction of offset. (Offset only available in MD
H
and MD
F
series)
DIP 5
Sets the highest amount of offset, typically 12°.
NOTE:
To set maximum offset DIP’s 5,6 and 7 will
need to be high for a total of 21°. The max. offset can also be set differently upon customer request.
DIP 6
Sets medium offset, typically 6°.
DIP 7
Sets the lowest amount of offset, typically 3°.
DIP 8
With DIP switch 8 in the ON position, the actuator will move to 4 positions. When switch 8 is off, the
actuator is limited to three positions. Switch 8 also changes the function of the output signals.
DIP 9
Run / Calibrate
Putting DIP switch 9 into the off position will disable the actuator positioning control, and the motor
will not move regardless of the input signals.
When DIP 9 is moved back into the on position, the actuator will perform its homing routine, and then
move to the position commanded by the input signals.

Actuator is moving, or has stalled and given up trying to reach
a requested position.
You may retry to reach any position by cycling alternate inputs
and trying the original again. Repeated failures to reach
position will require troubleshooting.
