4 General Information
3.2 Moving-behaviour of the actuator
How the actuator moves to the end limits depends on, whether the actuator is in Failsafe mode or in electrical mode.
3.2.1 Moving behaviour electrical mode
• Moving in Failsafe direction
In this case the actuator moves in Failsafe direction electrically by motor till the adjusted electrical end position is
reached. If the end limit is set to travel dependent, the actuator stops at this point. If the end limit is set torque
dependent, the actuator moves electrically till the end position. In the end position the electrical holding brake is
released and the actuator build up the torque by the tensioned spring.
NOTE: For torque dependent end limit, the end position should be set in a sufficient range before the mechanical
end position to avoid damage on the valve.
•
Moving counter Failsafe direction
The actuator moves to the end position electrically by motor. If the end limit is set torque dependent the torque is
build up by the motor.
NOTE: For torque dependent end limit the end position should be set in a sufficient range before the real end position
to avoid damage on the valve.
3.2.2 Moving behaviour failesafe mode
• Moving in Failsafe direction
In Failsafe mode the actuator can only move in Failsafe direction. When the electrical holding brake is released the
actuator moves against the end limit by spring. In this case the end limit is generally torque dependent. The torque
in end position is build up by the residual spring torque. Travel depended positioning of the end limit is possible by
adjusting the mechanical end stops from the actuator. Thus the mechanical end position can be set from 85° to 95°.
CAUTION: The mechanical end stops in the actuator are not designed to be moved against by torque regu-
larly!
4 General Information
4.1 Serial number
See operating manual ACTUSMART CM.V1.2, section 2.2, page 23
4.2 Protection class
See operating manual ACTUSMART CM.V1.2, section 2.4, page 24
4.3 Mounting position
See operating manual ACTUSMART CM.V1.2, section 2.5, page 24
4.4 Direction of rotation
The standard direction of rotation for the actuator is:
• Clockwise = The actuator runs counter to the Failsafe direction
• Counter-clockwise = The actuator runs in the Failsafe direction
Which direction, opening or closing of the fitting causes, depends on:
• The Failsafe direction of the actuator
• The closing direction of the fitting
All the information in this operating manual refers to the standard direction of rotation.
