2.2 Short description
Multi-turn actuator Definition in compliance with EN ISO 5210:
A multi-turn actuator is an actuator which transmits to the valve a torque for at least
one full revolution.It is capable of withstanding thrust.
AUMA multi-turn actuators are driven by an electric motor and are capable of
withstanding thrust in combination with output drive type A. For manual operation,
a handwheel is provided.Switching off in end positions may be either by limit or
torque seating. Controls are required to operate or process the actuator signals.
Actuator controls The AUMA MATIC actuator controls are used to operate AUMA actuators and are
supplied ready for use.The controls can be mounted directly to the actuator but also
separately on a wall bracket.The functions of the AUMA MATIC controls include
standard valve control in OPEN - CLOSE duty, position indications and different
signals right through to position control.
Local controls Operation (via push buttons), setting and indication can be performed directly at the
controls (contents of these instructions).
