Self-retaining when leaving the factory in both direction (cw and ccw).
12.1.8. Dead band
The dead band prevents operation to a new setpoint position within a specified band.
Required user level: Specialist (4) or higher.
Customer settings M0041
Multiport valve M1140
Dead band M1145
Default value: 0.00°
Setting range: 0.00 – 36.0° (degrees)
12.1.9. Correction of inertia
Due to reaction times and inertia, each Multiport valve has a specific inertia. This
can be compensated by inertia correction.
Required user level: Specialist (4) or higher.
Customer settings M0041
Multiport valve M1140
Overrun M1656
Default value: 0.00°
Setting range: 0.00° – 10.0° (degrees)
12.1.10. Backlash compensation
Adjustable backlash compensation of the overall system including valve coupling.
Required user level: Specialist (4) or higher.
Customer settings M0041
Multiport valve M1140
Backlash comp. M1146
Default value: 0.00°
Setting range: 0.00 – 36.0° (degrees)
12.1.11. Signalling behaviour of positions: set/check
Reaching of a point (valve port) can be signalled:
●
via bus (see separate instructions)
●
via indication lights (LEDs) of the local controls or
(refer to chapters <Indications> <Indication lights>)
●
via output contacts
(ref
er to chapters <Indications> <Assignment of outputs>)
Signal behaviour, this means the signal behaviour upon reaching a position, is set
via parameter MPV sign. beh. 1.
Customer settings M0041
Multiport valve M1140
MPV sign. beh. 1 M1147
Default value: No signal
Setting values:
No signal
A: Signal behaviour Off. Position is not signalled.
C________|¯¯¯¯¯¯¯¯O
B: Signal is active from reaching the position up to 360°.
C¯¯¯¯¯¯¯¯¯|_______O
C: Signal is active from 0° until the position is reached.
C_______|¯|_______O
D: When passing the position, a pulse signal is issued. The pulse range (range +/–
around the pivot point) depends on the set hysteresis.
