Switching the tolerance level for valve supply

U and U
Q1
The threshold 20.4 V and 21.6 V can be adjusted for different
valve series (see Tab. 8 on page 70). In the delivery condition, the
threshold is set to 21.6 V (10%) (S1.7/1.8 set to OFF). If the
supply voltage for the valve control drops below this threshold,
a diagnostic message will be generated.
Note
The diagnostic message is displayed if a
valve reports an overload or short circuit.
This diagnostic message is only displayed
as long as this valve is controlled.
Switches 1.2 to 1.5 have no function (are not
assigned).
Switch 1.6 is reserved. It must be set to
OFF!
The threshold 20.4 V/21.6 V can be adjusted
for different valve series.
