Operating and installation instructions
Thrust actuator ARI-PACO
®
2G 1,6D/Y
6.2.3 Initialization
NOTE !
Automatic mode cannot be activated unless the actuator has been initialized!
After the ARI-PACO
®
2G 1,6Y actuator has been
mounted on a valve, it must be initialized in order to
determine the full lift and the type of control (3- point or
analogue).
The desired control signal must be connected and set
for this purpose (refer to 6.2.1 Configuring the control
signal).
You can start an initialization run in any operating
mode by pressing the Reset button for longer than two
seconds. The yellow "Out of specification" LED blinks
when the initialization run is active. The actuator
automatically travels to the two final positions in order
to determine the valve lift.
You can cancel the initialization run at any time by
pressing the Reset button again briefly or by sliding the
"Man" switch.
If 3-point control is detected, an LED mounted directly
above the 3-point connector lights up continuously.
If analogue control is detected, the LED above the 3-
point connector only lights up when the electronics are
controlled by a 3-point signal.

NOTE !
Drives the actuator during the initialization of its valid travel range, the initialization will
be cancelled and the red and yellow LEDs lit. This may cause in an incorrectly set stem
excess length, wrong column lengths or even a missing valve.
