Adjustment

NOTE: The minimum position current input (zero point)

potentiometer and maximum position current input (span)

potentiometer can be physically turned indefinitely; but they

have an effective limit of 25 turns. Relative to the start point (4

mA / 0 degrees), rotating the post CW causes the actuator to

drive toward 90 degrees. Conversely rotating the pots CCW

causes the actuator to drive back toward zero. This is true of

both the START POINT and SPAN adjustments.

NOTE: There is a slight delay (approx. 3 seconds) in actua-

tor movement when a potentiometer is adjusted. Make final

adjustments slowly to prevent over adjusting. If adjusted prop-

erly, when the unit just begins to drive is should stop within 5

degrees. Over adjusting will lower the actual start point.

3. With the desired current input for the minimum position ap-

plied (typically 4 mA), adjust the zero point potentiometer

so the actuator shaft drives to it's zero point (minimum

position). It is best to adjust the start point potentiometer

until the actuator shaft just starts to move off its zero point.

Maximum Position Calibration

1. Apply power to the actuator, then turn on the "current cali-

brator".

2. Adjust the "current calibrator" until the mA input equals the

desired finish point (maximum position). This is typically

20 mA.

Do not apply a voltage source input to a CP-

9302 actuator drive that is configured for cur-

rent input . Doing so may damage the drive .

NOTE: After adjusting for deadband or input, the drive will

need to be re-calibrated. Please follow procedure on page

5 and page 6.

Potentiometer Adjustment and Jumpers

The potentiometer adjustments and the jumpers are located under the metal cover of the CP-9302-702 (the black box).

3. With the desired current input for maximum position (typi-

cally 20mA), the actuator will drive towards 90 degrees.

Once the actuator stops, adjust the span potentiometer so

the actuator shaft drives to the maximum position. It is best

to adjust the span potentiometer until the actuator shaft just

moves to its finish point.

4. Remove the current calibrator and turn off power to the

actuator. Then, reconnect the drive's leads to the controller.

5. Reinstall the cover.

6. Reapply power to the actuator and turn on the controller.

NOTE: Occasionally, an adjustment to the input span setting

results in a change to the start point setting, due to a small

interaction between these two settings. After adjusting the

input span potentiometer, ensure that both settings meet

requirements by repeating steps 7 - 9.

NOTE: When setting the potentiometers; only move the

actuator shaft in one direction. If the shaft is moved in opposite

direction, deadband will effect the setting.

Static charges produce voltages high enough

to damage the electronic components . Follow

static electricity precautions when servicing the

device (s) .
