Two Position Microelectric

Valve Actuator

(Control module serial numbers starting with EM2C)*

The microelectric actuator consists of a control module, a stepper motor/gearbox assembly, a manual

controller (use is optional), a universal AC input (100-240 VAC, 50-60 Hz) to 24 VDC power supply,

and the interconnecting cables. The actuator is self-adjusting from 30° to 90° – no valve alignment is

necessary. Once a valve is installed by tightening the clamp screw, the actuator senses the positive

stops within the valve and memorizes them in the first four moves.

The time it takes a valve to cycle from Position A to Position B

depends on the amount of rotation involved. To determine the

number of degrees in the angle of rotation, divide 360° by the

number of ports in the valve. Then consult the table at right.

Installation and Use

Getting Started

Figure 1 on the next page shows how to connect the various actuator components. There are four

connectors on the control module, keyed and sized to prevent incorrect connection.

Cable and Connector Functions

Input power

(20-30 VDC, with 24-28 VDC preferred) is supplied through

a coaxial connector: the inner pin is + voltage and the outer pin is ground.

The average DC current requirement is 2.5 amps. Standby current draw

is 60 milliamps. The actuator should not share a power supply with

other noise-sensitive electronics, as the high current draw can cause

problems.

Motor driver output

is through the five-pin connector: pins 1, 2, 4, and 5

carry the stepper motor phase drive signals. Pin 3 is grounded and

tied to the cable shield to reduce electrical noise.

A three-pin connector is used for the

RS-232 interface

: pin 1 is ground,

pin 2 is transmit to the host computer, and pin 3 is receive from the

host. (A discussion on serial control of the actuator starts on page 3.)

The ten-pin connector is for the

manual controller

or for

digital input/output signals

; the actuator can be

controlled by

either

both

. The manual controller has a through port, so an additional cable can

provide simultaneous control by an external system. (Digital control of the actuator is discussed on

page 3.)
