NSTALLATION
Fluidic connection of the TOP Control 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 difference 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.
Remove the protective caps from the valve and the TOP Control Continuous.
