WARNING!
Directly after connecting the voltage to the
actuator, a zero calibration is automatically
performed when the absolute travel adjust
-
ment is set (state of delivery), causing the
actuator stem to move.
Do not touch the actuator stem or obstruct it
to avoid risk of injury to hands or fingers.
NOTICE
During zero calibration, the control valve
moves through a part of the travel range.
As a result, do not connect the wires of the
actuator while a process is running. Instead,
close the shut-off valves in the plant first.
Connect the 6-wire cable according to
Fig. 4.
