1.GENERAL
This is a quarter turn electronic control actuator series.
The modulated actuators are operated with 4~20mA DC(or 1~5V DC) direct signals from a computer.
The precision (control resolution) of 1/250 is far higher than those of conventional pneumatic systems.
FEATURES
1. High control resolution of more than 1/250 with the original servo control pack.
2. Compact design with worm drive and robust aluminum die cast body.
3. Easy direction mode setting (Direct or reverse).
4. Easy mode selection (open, close or stop) during signal interruption.
5. Plural protections (thermal motor protector etc.).
6. Water protection: NEMA-4X (to IP-66).

4. OPERATION PRINCIPLE
4-1 Operation principle
The system makes computation between input signals (4~20mA DC) and position signals, then turns the motor in
direction to balance them, and stops the motor when they are balanced.
The motor torque is transmitted through the worm structure to the actuator shaft.
Rotation direction (direct or reverse) is selectable at the setting switch.
The backlash revision type potentiometer detects and feedbacks the shaft position to the control pack.
The system always controls shaft position at the correlated rates with input signals.

CAUTION ON ENVIRONMENTAL INSTALLATION CONDITIONS
5.INSTALLATION
5-1 Installation
Cautions on indoor installation
*Avoid a hazardous place, as this is not an explosion-proof type.
*Cover whole the unit, when installing the unit in a place with water or material splashes.
* It is recommendable to reserve a space for manual maintenance work.
(depends on installation conditions.)
Caution on outdoor installation
* To avoid rainwater or direct sunlight, it is necessary to cover or shade whole the unit.
(This concerns temperature rise in the unit, and anti-climate property of seals used.)
* It is recommendable to reserve a space for manual maintenance work.
(depends on installation conditions.)
