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 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 position of the stop can be approach‐
ed only in case of a manual initialization
The second position of the stop can be ap‐
proached only in case of a manual initialization
The position of the stop or the measuring
span is beyond 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 ac‐
tuators.
● Adjust the effective lever length of linear
actuators as per the measuring range.
● Wait.
● Wait.
● Wait.
● Wait.
● Wait until "FINSH" is displayed. Initializa‐
tion was completed successfully.
1. Approach first position of the stop with the
button or .
2. Acknowledge using
1. Approach second position of the stop with
the button or .
2. Acknowledge using
● Approach a different 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.
● Use the button to acknowledge; the re‐
maining 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.
