6.2.6 Automatic Malfunction message, ARI-PACO 0,85 Y
If during the valve travel a blockage from a foreign body occurs in the pipeline, the drive
notifies this malfunction by means of a feedback signal of approx. 13 V DC (only without
voltage limitation of the Z diode between connector A or 0 possible), on connection terminal
A. Furthermore, the LED beneath the drive housing blinks.
By means of an automatic blockage removal algorithm, the actuating drive next attempts to
free the valve blockage by itself by briefly lifting the valve cone a number of times.
Additional malfunction messages by means of potential-free relay contacts can be made
with the relay card (accessories). The relay card can be retrofitted easily. Refer to Pt. 5.5.3 .

Switch 4
Actuating direction for partial initialization.
In the case of power loss or manual switched usage, the actuating drive carries out a
partial initialization for safety reasons. The direction valve open or valve closed are
determined by the plant conditions.
