Micro – Electric Multiposition Valve Actuator Installation and Use The microprocessor-based multiposition actuator consists of the control module, the stepper motor/ gearbox assembly, a manual controller (use is optional), a 110 or 220VAC to 24VDC power supply, and the interconnecting cables. 1.95"...

Motor driver output is through a 10 pin connector. The 26-pin connector is for the manual controller or digital input/output signals. (The actuator can be controlled by either or both. The manual controller has a through port, so an additional cable can provide simultaneous control by an external system.) The three-pin connector is for a serial RS-232 interface.
Valve Mounting Cheminert valves With the valve and actuator in Position 1, engage the drive pin of the valve with the coupling of the actuator. Rotate the valve by hand until the pin on the actuator clamp ring lines up with the hole in the face of the valve.

Digital Input / Output Protocol Digital input/output control of the multiposition actuator is designed for simplicity and flexibility of function. The simplest control of the actuator can be accomplished with two output control lines – STEP and HOME. On the other hand, the actuator can accept a latched BCD input with manual and automatic direction signals.
