How do I reverse direction on a 1000 series actuator?
- Apply a 4mA / 0vDC command signal - whichever applies to your actuator.
- Let the actuator run until it stops.
- Continue applying the 4mA / 0vDC signal, depress and hold the zero pushbutton.
Rotate the encoder knob (slowly, the encoder is speed sensitive) to run the actuator
halfway back to the opposite end of travel.
- Release the button
- Apply a 20mA / 5vDC /10vDC signal - whichever applies to your actuator.
- Let the acutator run until it stops.
- Continue applying the 4mA / 0vDC signal. Depress and hold the zero pushbuttons.
Rotate the encoder knob to run the actuator the rest of way to the low end of travel. Release the pushbutton.
- This completes the reversal process and your actuator should now be running the opposite direction for an increase in signal.

How do I restore the factory default settings on a Digital 1000 Series actuator?
- Hold down the speed, LOS and deadband pushbuttons at the same time until you see D5 illuminate (approx. 3 seconds).
- Factory settings are now restored and you can begin re-calibration.

What is the difference between "Remote Feedback" and "Local Feedback"?
- Remote Feedback is 4-20mA feedback from the actuator to the amplifier.
- Local Feedback is potentiometer feedback from the actuator to the amplifier.

The motor in my actuator hums, but the output shaft doesn’t move. Is it jammed?
There are two reasons for a unit humming. It is due to either an external binding condition, or an internal failure.
- First verify that no external binding condition exists.
- Power down the unit and check the movement of the device being actuated.
- If there is no external binding condition, then the unit has either a mechanical failure within the drive train,
or an electronic failure of the control amplifier. In both internal cases, the unit is in need of service.

|
How often do I need to lubricate my actuator?
- Never, RPC actuators are permanently lubricated.
|
|
My actuator has a handcrank, but it doesn’t seem to move the output shaft. What am I doing wrong?
- Ensure the hand crank is engaged by pressing in the handle, or pressing in the manual override push button.
|
|
How do I get my actuator to stop oscillating when it gets to its commanded position?
There are two basic options:
- Widen the deadband setting on the actuator. (Refer to the Instruction Manual for procedure.)
- If the unit has an amplifier with a dynamic braking feature, and the feature is not enabled, refer to the IM to enable the feature.
|
|
Why aren’t my command signal and feedback signal the same?
- Assuming there is a feedback signal, but just not matching the command, then there is a calibration problem with either the amplifier or the transmitter. Refer to the unit’s wiring diagram to properly calibrate the amplifier and/or transmitter.

Does my actuator come with a warranty?
Yes, either 1 year or 2 years depending on the model.
