pneumatic installation for topCONTROL type 8630

the control valve is driven by compressed air via the topControl.
Remove the protective caps from the connectors on the TopControl and the valve.
Apply the supply pressure to port "1".
The supply pressure necessary for complete opening or closing of the valve may lie between the minimum
values of 3 and 6 bar, depending on the actuator. The permissible maximum value for the control pressure is
7 bar. The values for the pressure supply are given under p
Attach the exhaust line or silencer to port "3".
Control medium:

fluid connections of the topControl continuous

Remove the protective caps from the valve
and the TOPControl Continuous.
Apply the supply pressure to connection "1"
(3..7 bar, instrument air, free from oil, water
and dust)
Attach the exhaust line or silencer to
connection „3"
note
Maintain the applied supply pressure, without fail, at least 0.5 - 1 bar over that required to
bring the pneumatic actuator into the end position. This assures that the control behaviour in
the upper region of the stroke will not be significantly affected negatively if the pressure diffe-
rence is too small.
Keep variations in the supply pressure as low as possible during operation (max. ± 10%).
With larger variations, the controller parameters calibrated with the AUTOTUNE function will
not be optimal.
