6.2.1 Automatic initialization, ARI-PACO 0,85 Y
The ARI-PACO 0,85 Y mounted on the valve can be automatically initialized. By automatic
initialization, the ARI-PACO 0,85 Y adjusts itself automatically to the valve travel. A
distinction is made between full initialization and partial initialization.
Full initialization, ARI-PACO 0,85 Y
In the case of full initialization, which is
started by means of a short push on the
button INIT, the operating end positions are
determined. During the full initialization, the
valve is once fully opened and fully closed,
the hand wheel makes short intermediate
stops. During the initialization, the LED
next to the button INIT blinks. The button
INIT is located beneath the drive housing;
refer to figure
Fig. 31
ATTENTION !
- Full initialization may not be carried out under insufficient voltage!
Partial initialization, ARI-PACO 0,85 Y
A partial initialization should be carried out for safety reasons after every voltage loss or
after every time the valve has been switched to manual operation. The direction valve
open or valve closed should be carried out according to plant conditions.
