Terms for the oscilloscope- and monitor view:
All Parameters are displayed with a resolution
of 0,01. Please mind the units.
Parameters shown in the Oscilloscope are
sampled with 1 ms. The solenoid current has
a lower sampling rate. Please take the sole-
noid display only for informational purpose,
but do not take these values for quantitative
validation.
Do not start up a pump or hydraulic system
before loading the correct control program
for the particular pump size to the attached
module. Damage of the pump or components
connected to it can be the result.
