Siemens GHT336.1A/35 Quick Start Manual page 2

Use
For ventilation system with large area damper or combination damper.
Mechanical design
The actuator is driven by an on/off control signal from an external controller, and generates a
rotary motion which is transferred to the external link mechanism via mechanical transmissions,
and drives the damper shaft for rotary movement from 0° to 90°.
The actuators have a reversible asynchronous motor and gear train.
For GHT336.1A/35, the spring is fitted with a handwheel shaft, and the handwheel is engaged
when pushed in. For others, the worm shaft is fitted with a direct-acting handwheel. Manual
operation can be performed at any time using manual/electric auto changeover.
