P--- X Measuring range was exceeded, the potenti‐
ometer is in the inactive zone, the transmis‐
sion ratio selectors or the e󹪜ective lever arm
are not adjusted as per the actuator travel
• Switch the transmission ratio selector to
90°, especially in the case of part-turn ac‐
tuators.
• Adjust the e󹪜ective lever length of linear
actuators as per the measuring range.
RUN 1 X Initialization was started, part 1 is active (the
direction of action is determined)
• Wait.
RUN 2 X Initialization part 2 is active (actuator travel
check and determination of stops)
• Wait.
RUN 3 X Initialization part 3 is active (determination
and display of travel times)
• Wait.
RUN 4 X Initialization part 4 is active (determination of
the minimum controller increment length)
• Wait.
RUN 5 X Initialization part 5 is active (optimization of
the transient response)
• Wait until "FINSH" is displayed. Initializa‐
tion was completed successfully.
• For option -Z P02: Wait.
RUN 6 X Initialization part 6 is active (determination of
Valve Signature)
• Wait until "FINSH" is displayed. Initializa‐
tion was completed successfully.
YEND1 X The 󹪝rst position of the stop can be approach‐
ed only in case of a manual initialization
1. Approach 󹪝rst position of the stop with the
button
or .
2. Acknowledge using
button.
YEND2 X The second position of the stop can be ap‐
proached only in case of a manual initialization
1. Approach second position of the stop with
the button
or .
2. Acknowledge using
button.
RANGE X The position of the stop or the measuring span
is beyond the permissible measuring range
only in case of a manual initialization
• Approach a di󹪜erent position of the stop
using
or button and acknowledge
using
button.
• Move the friction clutch until "ok" is dis‐
played, and then acknowledge with the
button.
• Terminate the initialization process using
the
button, switch to the P-manual
mode, and correct the actuator travel and
the position displacement sensor.
ok X The permissible measuring range of end posi‐
tions is achieved only in case of a manual ini‐
tialization
• Use the
button to acknowledge; the re‐
maining steps ("RUN 1" to "FINSH") run au‐
tomatically.
