Valve Rng Calib.
Upper Valve Rng
0.0 to 100.0 %
Normally, the valve range is determined automatically during Auto Adjust. A partial run of Auto Adjust
that is limited to the control parameters or valves and fittings without end stops, however, requires
manual adjustment of the valve range.
CAUTION
Danger of crushing!
Following manual adjustment of the end positions, it is essential that the parameter ‘Control at
100%’ is set to ‘On’. Otherwise, the valves and fittings may be driven at full speed to an end position.
• Do not reach into the adjustment mechanism.
Note
If after automatic adjustment, the valve range is manually rotated (old min. = new max. => old max. =
new min.) the device no longer reacts to set point changes. A constant process value of 128 flashes on
the display.
