16.3. signal priorities
if a valve has several overlapping states, the following priority list applies:
Internal Fault (fault color: 450 ms ON, 50 ms OFF)
1.
Manual operating mode is active, e.g. by magnetic manual control - see chapter
2.
Control (fault color: 50 ms ON, 450 ms OFF)
Maintenance/service prompt (fault color: 1 s ON, 3 s OFF)
3.
Other fault, e.g. position measuring system not taught, bus error or other (see chapter
4.
if position feedback signals overlap, the following logic applies:
ON principle, S4 has the highest priority, descending to S1 (i.e. S4 - S3 - S2 - S1).
