Actuating time limit
This function can be used to set the opening and closing times for the entire stroke, and thus limit the control
speeds.
When performing the
X.TUNE
function, the minimum opening and closing time are entered for the
entire stroke for Open and Close. This facilitates movement at maximum speed.
Factory setting: factory-set values through the
X.TUNE function
If the control speed is to be reduced, values can be entered for Open and Close which lie between the minimal
values to be determined by
X.TUNE
and 60 s.
Actuating time Open: Opening time for the whole stroke (in seconds)
Setting range: 1...60 seconds
Actuating time close: Closing time for the whole stroke (in seconds)
Adjustment range: 1...60 seconds
