permanent blinking in the fault color:
- Teaching does not occur
or
- Teach-Reset has been performed or
- Bus error
permanent blinking in the color for that position:
Signal from position 3
450 ms 50 ms Internal Fault (fault color)
50 ms 450 ms Service mode / manual control active
(fault color)
125 ms 125 ms Signal from the external initiator S4
(like "color for position 3")
1 s 3 s Signal in fault color (and additionally
color of the corresponding valve position):
Maintenance/service required
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. 17. Service Mode / Manual
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. 16.2. Blinking Pattern
& Fault Signaling)
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).
s1 s2 s3 s4 fault priority note / Blinking patterns
active active active active S4 Blinking in S4 blinking pattern (if S4 has been acti-
vated by DIP) since S3/S4 has priority over S1 and S2
active active S4 Blinking in S4 blinking pattern, if S4 has been acti-
vated by DIP
active active active S3 Blinking in S3 blinking pattern since S3/S4 position
has priority over S1 and S2
active active S2 Position feedback of S2 has priority
