ADJUSTMENTS
Start Point Adjustment
The start point of these actuators is factory-set to 6 Vdc and is field-adjustable from 2 to
12 Vdc. If a start point other than 6 Vdc is required, proceed as follows:
1. Peel back the TAC label from the drive, to expose the start point adjustment
potentiometer. Refer to Figure-3.
2. Disconnect the red, yellow, and blue leads of the drive from the controller.
3. Connect the leads of TOOL-202 to the like-colored leads of the drive.
4. Connect a DVM to the yellow (OP1) and blue (COM) leads of the drive.
5. Adjust TOOL-202 until the DVM reading equals the required start point voltage (2 to
12 Vdc).
6. Adjust the actuator start point, using a small, single-slotted screwdriver, so that the
actuator shaft just begins to rotate when the desired voltage is applied.
7. Press the label back onto the drive.
CHECKOUT
After the entire system has been installed and the actuator has been powered up, the
following checks can be made for proper system operation.
Positioning with
Controller
If the sensed media is within the controller’s setpoint range, the actuator can be positioned
by adjusting the controller setpoint up and down. Check for correct operation of the actuator
(valve or damper) while it is being stroked.

Supply
These terminals are marked L1 & L2 on 120V and 240V
actuators. 120V and 240V actuators must not have a built-in
transformer, or if a built-in transformer is present, remove red
and blue leads from terminals 7 and 8, and tape off.
CP-8301-024 can be used with the following electric
actuators: MP-361, 371, 381, 382, 2113-500 and 9713.
CP-8301-120 can be used with the following electric
actuators: MP-465, 475, 483, 485, 486, 495, and 2150-500.
CP-8301-240 can be used with 240 Vac electric
actuators. (Available as a standard option.)
Actuator rotates clockwise on increase in input signal.
To rotate actuator counterclockwise on an increase
in input signal, reverse blue/black and red/black leads
and reverse brown/black and brown/white leads.
