Applications

The AM-703 span adjustment module changes non-standard current and volt age sign als into a 2 to 10 Vdc signal.

The AM-704 modulation interface converts signa l 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.

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.

4. Punch out a plug to route wiring into box. Two screw-in caps are provided.

5. Connect wires (Figure-13) and set output switch to either 2 to 10 Vdc or 0 to 10 Vdc (Figure-8).

6. Secure front cover with screws removed in step one.

3. Use two mounting screws (customer supplied) and appropriate drill to drill and mount

4. Remove the two screws from the front cover plate and separate the cover from the circuit board (Figure-9).

5. Position the circuit board behind the mounting surface. The wire screw terminals should be at the bottom.

6. Position the front cover plate and secure it to the circuit board with the two screws removed in step 4.

The dial has a sealing O-ring for moisture resistance. A thin gasket may be placed between the front cover plate and the mounting surface.

7. Connect wires (Figure-13).
