Argus  E25 MOD II -  Operating Instructions 

 
 

28 

  

 

Automatic operation 

Switching the electric motor in the unit on 

generates a rotary motion. This is trans-

mitted to the reduction gear by a timing 

belt. This causes the valve stem in the 

unit to turn (see “Uses and function”). 
In automatic operation, the end positions 

of the unit are recorded and signalled by 

end-position limit switches (4.2). 
The end-position limit switches are inside 

the unit.  

 

 
The end-position limit switches are indi-

vidually adjustable by resetting the 

switching cams (4.11).  
 
 
 
 
 
 
 
 
 

 

ATTENTION!

 

Setting the end-position limit 

switches, even after repairs, shall 

only be carried out by authorised 

personnel. 

During operation do not carry out any 

other activities on the actuator or valve.
