Q1
and U
Q2
The threshold 20.4 V and 21.6 V can be adjusted for different
valve series. In the delivery condition, the threshold (see
Table 19 on page 92) is set to 21.6 V (10%) (S 3.7 and S 3.8 set
to ON). If the supply voltage for the valve control drops below
this threshold, a diagnostic message will be generated.
6.1.4 Diagnosis
The diagnosis can be read using the module states.
