ec tower technical manual
• To calculate the torque required, the specifications supplied by the damper
manufacturers concerning the cross-section, the design, the installation site and the
ventilation conditions must be observed.
• The device contains electrical and electronic components and must not be disposed
of as household refuse. All locally valid regulations and requirements must be
observed.
Product features
Simple direct mounting
Simple direct mounting on the damper spindle with an universal spindle clamp,
supplied with an anti-rotation device to prevent the actuator from rotating.
Manual override
Manual override with push-button possible (the gear is disengaged for as long as the
button is pressed or remains locked).
Adjustable angle of rotation
Adjustable angle of rotation with mechanical end stops.
High functional reliability
The actuator is overload protected, requires no limit switches and automatically stops
when the end stop is reached.
