AM-703…6, 708

Actuator Accessories for Schneider
Electric Proportional SmartX Actuators

Applications

The AM-703 span adjustment module changes non-standard
current and voltage signals into a 2 to 10 Vdc signal.

The AM-704 modulation interface converts signal input from a
pulse-width modulated input signal to an analog 2 to 10 Vdc
signal.

The AM-705 and AM-706 positioners are used for remotely
controlling proportional actuators. The AM-705 is for surface
mounting. The AM-706 is for flush mounting.

The AM-708 500 ohm resistor converts a 4 to 20 mA signal to a
2 to 10 Vdc signal.

Installation

AM-703
Set the circuit board jumper to fit the application.

Figure-1 Jumper Settings.

The AM-703 may also be used to sequence several actuators from one signal source. This is done by adjusting multiple mod­ules to work at different input ranges. (Example: 2 to 5 Vdc, 5 to 8 Vdc, 8 to 11 Vdc, etc.)

Calibration

1. Attach a variable signal source to the AM-703 input and power wires.

2. Apply power.

3. Input the minimum signal level.

4. Adjust the offset potentiometer to produce a 2 Vdc signal at the output. A clockwise rotation of the potentiometer screw
will increase the output signal. See Figure-2.

5. Input the maximum signal level.

6. Adjust the span adjustment to produce a 10 Vdc signal at the output. A clockwise rotation of the potentiometer screw will
increase the output signal. See Figure-2.

7. Double check the input-output calibration and install.
