5. Screw the pneumatic connections (not included in the
scope of delivery) into the threaded adapter and tighten
carefully.
6. Make sure that the ventilation lines are always depressur-
ized.
7. Connect the ventilation lines tension-free and without any
bends or knots and install them in a dry environment.

Hazardous situation
▶ Risk of injury or damage possible.
For correct commissioning, the
●
product must be calibrated to the pro-
cess valve by means of the initializa-
tion process.
During this commissioning, the valve is
●
automatically opened and closed sev-
eral times. It must therefore be en-
sured in advance that this does not
lead to a dangerous situation.
NOTICE
Incorrect initialization
Always carry out initialization without operating medium
●
pressure on the process valve
NOTICE
For delivery of the product assembled on a valve at the
●
factory, the complete construction is already ready for op-
eration at a control pressure of 5.5 to 6 bar without oper-
ating pressure. A reinitialization is recommended if the
plant is operated with a different control pressure or if the
mechanical end positions have been changed (e.g. seal
replacement on the valve or actuator replacement). The
initialization is retained even in the event of voltage
cutoff.
NOTICE
For delivery of the product without factory setting (e.g. for
●
delivery without valve) initialization must be carried out
once for correct operation. This initialization must be re-
peated every time that the process valve is changed (e.g.
seal replacement or actuator replacement).

ð Automatic initialisation is carried out. The initialisation
phase lasts a few minutes, during which the process
valve is opened and closed several times. The initial-
isation process is ended automatically.
