and electronics technologies
The gear unit provides high
efficiency, maintenance free
operation.
Motor in insulation class F. Measuring
and monitoring of both current and
temperature provide full protection.
Introduction of efficient Man-machine
interface simplifies commissioning with
user guidance.
Motor and control cables are connected by
using screw type terminals or PCB plug-in
terminals to ensure reliable electrical
contact.
Magnetic angle sensors for contact-less
position detection, are operated by means
of the signaling gear to detect the current
valve position and torque.
A centrifugal lock prevents the hand wheel
from engaging before the motor has come
to a standstill.
