Function
A DC-motor actuate the main shaft via a gearbox. The path control is done via two integrated micro
switches and signaling via two potential free limit switches. They are operated by cams on the main
shaft, before it reaches the limit switch. A mechanical travel limit is omitted. The visual position
indicator provides information on whether the valve is open or closed. On the standardized interface
fittings valves can be mounted directly or through appropriate adapters. The electrical connection is
via DIN connector. The type label and the wiring diagram to make every actuator easily identifiable.

ATC:
The control room heater is integrated and active as long as voltage is applied to the power
connector.
mechanical unlocking:
The actuator electronics enables easy switching from automatic mode
(AUTO) to Manual mode (MAN). The transmission is automatically unlocked, when limiter is active,
by a slight backward rotation of the motor.
Integrated Systems:
ETL (electronic torque limiter)
AVS (auto voltage sensing)
ATC (automatic temperature control)
PEC (protected electrical connection)
