CAUTION!
danger from wrong setting of the valve type.
If a different type of valve is selected from the valve actually used whose
coil has very different characteristics, the function of the valve can be se-
verely impaired. When using the form spring valve, Type 2822, the input of
a wrong valve type can lead to irreparable device damage!
• always set the valve type correctly.
For this parameter, the value „----" (no valve) is set as default value in the
delivery condition. If no valve is selected, the coil remains de-energised.
nOTe!
The choice of valves depends on the device type being used.
Due to the scatter of the valve types with respect to friction character-
istics and the relationship between sensitive control behaviour and low
hysteresis or low noise development and larger hysteresis, it can be
advisable to deviate from the recommended PWM frequencies (see also
chapter 8.3.3 VAdJ - Fine tuning of the valve frequency)
