Meaning/cause
Measuring range was exceeded, the potenti‐
ometer is in the inactive zone, the transmis‐
sion ratio selectors or the effective lever arm
are not adjusted as per the actuator travel
Initialization was started, part 1 is active (the
direction of action is determined)
Initialization part 2 is active (actuator travel
check and determination of end stops)
Initialization part 3 is active (determination
and display of travel times)
Initialization part 4 is active (determination of
the minimum controller increment length)
Initialization part 5 is active (optimization of
the transient response)
The first end position can be approached only
in case of a manual initialization
The second end position can be approached
only in case of a manual initialization
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 "RUN 1", no movement e.g. due to
the lack of compressed air
Measure
● Switch the transmission ratio selector to
90°, especially in the case of part-turn
actuators.
● Adjust the effective lever length of linear
actuators as per the measuring range.
● Wait.
● Wait.
● Wait.
● Wait.
● Wait until "FINSH" is displayed.
Initialization was completed successfully.
1. Approach first end position using
button.
2. Acknowledge using
1. Approach second end position using
or button.
2. Acknowledge using
● Approach a different end position using
or button and acknowledge using
button.
● Move the friction clutch until "ok" is
displayed, 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.
● Use the button to acknowledge; the
remaining steps ("RUN 1" to "FINSH") run
automatically.
Possible causes:
● Insufficient supply of compressed air.
● Restrictor(s) blocked.
● Actuator does not move freely.
Measures:
1. Eliminate possible causes.
2. Restart initialization.
