• MANUAL OVERRIDE OPTIONS
The EC series can be supplied
with four different Manual
Overrides
Low Torque for Spring Return =
“J.S.”Jack Screw
High Torque for Spring Return
= “MOG” Manual Override with
integrated Gear
Low and High Torque for
Double Acting = “MGDA”
Declutchable Manual Override
High Torque for Double and
Spring Return = “M.O.H.P”
Hydraulic Manual Override
• CONTROL SYSTEM
The EC series can be supplied
with a set of additional
components specifi cally
engineered and integrated
