Emergency Shut Off Actuator

ECR series

ECR PHOTO

Ultra high capacity electric double layer capacitor.

In case of power failure, electric discharge from built-in capacitor lets valve operate.

Capable of high-frequency operation (over 200,000 times), and maintenance-free.

When motor is not in motion, consumed electric power is less than 2W. Energy-saving design.

Output signal rating: 125V AC/0.5A , 24V DC/1A MAX.
Amp. required for control SW: 6mA (leak less than 1mA)

When the power is turned on, operation starts after capacitor

is charged.

* How to set the DIP SW

Set the MODE (DIP SW) as shown below.

It's in MODE A when shipped.

* Operation

MODE A:

SW OFF : turns clockwise SS output.

SW ON : turns counter-clockwise SO output.

MODE B

SW ON : turns clockwise SS output

SW OFF : turns counter-clockwise SO output.

* When power shuts off

MODE A:

turns clockwise SS output.

MODE B:

turns counter-clockwise SO output.
