Typ 3363, 3364, 3365
Start-up
ATTENTION!
Only run TUNE if necessary.
It is only necessary to adjust the position control again if the actuator has been dismantled and/or the
diaphragm or the valve body has been replaced, or if the valve is loose.
With the M.Q0.TUNE function, the tight closing point and the tight closing force can be adapted to the current
operating conditions. Due to the adapted sealing force, the service life of the diaphragm can be increased,
especially at low operating pressures.
With the X.TUNE function, the tight closing point is determined via the presettings for the maximum operating
pressure.
When executing the X.TUNE or M.Q0.TUNE function, the position control is adapted to the physical stroke of the
proportional valve used and the required sealing force is determined.
M.Q0.TUNE
With the M.Q0.TUNE function, the tight closing point must be approached manually. It is important that the valve
is not completely closed (see "Fig. 43"), only to the necessary seal closure point. Based on this position the
device uses an algorithm to calculate the optimum force for sealing
If necessary, adjust the position control using the M.Q0.TUNE function, see chapter "11.5.1" on page 83.
X.TUNE
Adjust the position control using the X.TUNE function, see chapter "11.6.1" on page 87.
When executing the X.TUNE function, the position control is adapted to the physical stroke of the proportional
valve used and the required sealing force is determined using the default settings.
Applying the operating pressure is not required, but does optimise the result of the X.TUNE.
The LED illuminated ring will light up orange while the X.TUNE is executed.
When X.TUNE is finished, the LED illuminated ring returns to its previous status.
11.6.1 Adjustment of X.TUNE position controller with keys in device
The 2 keys for triggering X.TUNE are located beneath the blind cover.

To unlock the blind cover, turn it anticlockwise and remove.
Devices with ATEX approval or IECEx approval are secured with a magnetic lock.
The removal of the cover is described in the supplementary instructions for the electromotive control
valves with ATEX approval and IECEx approval.
How to trigger the X.TUNE function:
