7.7.10 Travel limitation
If necessary, the travel can be limited in direction OPEN and/or CLOSE.
This prevents the end position(s) OPEN and/or CLOSED from being
approached in modulating duty. The actuator stops when reaching the set
position limit value. In operation mode LOCAL or REMOTE MODE, this limi
-
tation is not active. The valve can then be run into the end positions either
via the local controls or the remote control commands OPEN - CLOSE.
Figure 11 shows the limitation of the travel range:
