ADJUSTMENTS

The CP-9301 and CP-9302 actuator drives feature one jumper for selecting voltage or

current input, a second jumper for selecting 3% or 5% deadband, and potentiometers for

adjusting the input span and start point. The CP-9301 is preset at the factory for voltage

input, and the CP-9302 is preset for current input (Table-1). When necessary, these factory

presets may be changed according to the procedures in this section.

Voltage Input

Adjustments

When a CP-9301 has been left at its factory presets, the settings detailed in Table-1 apply.

If a CP-9301 requires adjustments to its deadband, startpoint, or input span, or if a CP-9302

is to be reconfigured for voltage input, make adjustments according to the following:

Caution:

• Do not apply a current source input to a CP-9301 or CP-9302 actuator drive that is

configured for voltage input (factory setting). Doing so may damage the drive.

• Static charges produce voltages high enough to damage the electronic components.

Follow static electricity precautions when servicing the device(s).

1. Turn off the controller signal to the drive’s input.

2. Turn off power to the actuator.

3. Remove the screw that secures the cover to the drive, then remove the cover. This

provides access to the start point and input span adjustment potentiometers, as well as

the input and deadband jumpers (Figure-9).

4. Disconnect the drive’s yellow and blue leads from the controller.

5. When reconfiguring a CP-9302 for voltage input, reposition the input jumper to the

voltage input setting, as shown in Figure-9.

6. Connect the leads of a suitable voltage signal source (voltage calibrator) to the

appropriate drive leads.

7. Connect a DVM to the yellow (drive input) and blue (COM) leads of the drive.

8. Apply power to the actuator, then turn on the voltage signal source.

9. If desired, reset the deadband by repositioning the deadband jumper.

10. Adjust the voltage signal source (voltage calibrator) until the DVM reading equals the

desired start point voltage (0 to 10 Vdc).

11. With the desired start point voltage applied, adjust the start point potentiometer, using

a small screwdriver, so that the actuator shaft

just reaches the start point
