Remove the main body cover 

 of the seismic 

detector close to you and, as shown in this figure, 

use a cotton swab (not possibly scratching the steel 

ball 

)  or an equivalent to softly press the steel 

ball 

 to release it from the receiving rod 

.  

(See "7.4 How to adjust the seismic detector" on 

page 12). 

Allow the seismic detector to activate by dropping 
the steelball

  from the receiving rod 

 

 
 
 

9.4.2 Shut-off valve

 

 

    

Warning

 

(1)Make sure that the power supply is not turned on and then start this procedure. 

*An electric shock can possibly be given.

 

 

 

Cautions

 

(1)Keep watching an opening indicator or an equivalent to conduct a manual operation and check 

the wide open and fully closed positions to prevent them from being exceeded. 

*If they are exceeded, the product will be damaged. 

(2)Make sure that the power supply is not turned on and then start this procedure. 

*The product can possibly be broken.

 

 

Lower the manual clutch knob below the 

electric operation machine and turn it by 90 

degrees clockwise or counterclockwise. 

(The connection to the motor comes off to 

allow a manual operation). 

Engage a monkey wrench or an equivalent 

with the hexagon of the connector portion 

(two facets of the manual operation shaft for 

200A) to conduct a switching operation. 

 To return to an automatic operation, return 

the manual clutch knob to the original 

condition.  In this case, make sure that the 

manual clutch knob has returned to the 

original condition. 

If it does not return to the original condition, 
slightly move the connector or the manual 
operation shaft.   
Before proceeding to an automatic operation, 
ensure to remove the monkey wrench and 
the manual handle.
