Meaning/cause
The end position or the measuring span is be‐
yond the permissible measuring range only in
case of a manual initialization
The permissible measuring range of end po‐
sitions is achieved only in case of a manual
initialization
Error in "RUN1", no movement e.g. due to the
lack of compressed air
Bar graph display of the zero point is outside
the tolerance range
Friction clutch was moved; "P 50.0" not dis‐
played when the lever is horizontal
"UP" tolerance range was exceeded or the in‐
active zone of the potentiometer was covered.
Possible only in case of part-turn actuators:
actuator travel is not in the range between 90
and 95%
"Up-Down" measuring span was undershot
Measure
● Approach a different end position using
or key and acknowledge using
key.
● Move the friction clutch until "ok" is
displayed, and then acknowledge with the
key.
● Terminate the initialization process using
the key, switch to the P-manual mode,
and correct the actuator travel and the
position displacement sensor.
● Acknowledge with the operating mode
button; the remaining steps ("RUN1" to
"FINSH") execute automatically.
Possible causes:
● Insufficient supply of compressed air.
● Restrictor(s) blocked.
● Actuator does not move freely.
Measures:
1. Eliminate possible causes.
2. Restart initialization.
1. Set between "P 4.0" and "P 9.9" ( >0< )
using friction clutch.
2. Continue using or
1. In the case of linear actuators, use the
or key to bring the lever
perpendicular to the spindle.
2. Briefly acknowledge using
(initialization is continued).
1. Increase the effective lever length of the
linear actuators or switch the transmission
ratio selector to 90°.
2. Briefly acknowledge using
3. Restart initialization.
1. Use the or key to move it in the
range between 90 and 95%.
2. Briefly acknowledge using
1. Decrease the effective lever length of the
linear actuators or switch the transmission
ratio selector to 33°.
2. Briefly acknowledge using
3. Restart initialization.
