The Pressure monitoring function can be used for detecting overpressure or
low pressure conditions inside the system, and if necessary to shut down the af-
fected system components in order to avoid system damage. So sollen Anlagen-
schäden vermieden werden.
Note:
The pressure monitoring function will only be available when an RPS type
Grundfos Direct Sensor
™
or an electronic pressure gauge is connected.
Overpressure
If the system pressure exceeds the adjustable switch-on value On, an error mes-
sage will appear.
If the shutdown option has been activated for the overpressure monitoring func-
tion, the solar system will be shut down as well in the case of a fault condition.
When the pressure reaches or falls below the adjustable switch-off value Off, the
system is switched on again.
Note:
For the Overpressure monitoring function, On has to be adjusted at least
0.1 bar higher than Off. The adjustment ranges will automatically adapt
to that.
Low pressure
If the system pressure falls below the adjustable switch-on value On, an error
message will appear.
If the shutdown option has been activated for the low pressure monitoring func-
tion, the solar system will be shut down as well in the case of a fault condition.
When the pressure reaches or exceeds the adjustable switch-off value Off, the
system is switched on again.
Note:
For the Low pressure monitoring function, Off has to be adjusted at least 0.1
bar higher than On. The adjustment ranges will automatically adapt to that.
