Low pressure (leakage)
If the system pressure falls below the adjustable switch-on value, an error message
will appear.
When the pressure reaches or exceeds the adjustable switch-off value, the mes-
sage disappears.
Note:
For the Low pressure monitoring function, the switch-off value has to
be adjusted at least 0.1 bar higher than the switch-on value. The adjust-
ment ranges will automatically adapt to that.
