Application

The CP-9301 and CP-9302 electronic actuator drives

process a variable input signal from a controller to

provide proportional control of an electric gear train

actuator. The CP-9301 is preset at the factory for

voltage input. The CP-9302 is factory preset for current

input and has additional wiring for connection to an

override switch, for those applications requiring an

external override of the input signal. These drives are

equipped with built-in jumpers and adjustable

potentiometers, so that the type of input signal,

deadband, input span, and start point may be reset in

the field when necessary.

Features

• Mounts directly onto TAC proportional, electric, gear

train actuators.

• Power is supplied directly from the actuator.

• May be used with all gear train actuator voltages and

frequencies.

• Jumpers for selecting either voltage or current input,

as well as 3% or 5% deadband.

• Adjustable span and start point potentiometers.

Mounting The drive may be mounted on either the left or right side of the actuator, in a conduit opening adjacent to the low voltage wiring compartment. Mount the drive onto an actuator as follows: 1. Remove the cover from the actuator, to expose its power wiring compartment and low voltage wiring compartment. Note that each side of the actuator casing features two 1/2" knockouts which provide access to these two compartments. 2.

WIRING Power Wiring The power for the drive is supplied directly from the shading coil windings of the gear train actuator onto which the drive is mounted. Refer to Figure-7 or Figure-8 for an installation wiring diagram.

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.

12. Determine the finish point of the actuator by adding the desired voltage span to the start point voltage. The finish point is the voltage that causes the actuator to just reach its rotational limit. Adjust the voltage signal source (voltage calibrator) until the DVM reading equals the calculated finish point voltage. 13. With the finish point voltage applied, adjust the input span potentiometer, using a small screwdriver, so that the actuator shaft just reaches its rotational limit.
PAGE 11
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 10 through 13, as necessary. 14. Turn off the current input signal to the drive and turn off power to the actuator. Then, reconnect the drive’s leads to the controller. 15.
