Pressure monitoring
Note:
The pressure monitoring function will only be available when an RPD type
Grundfos Direct Sensor™ is connected.
The pressure monitoring function can be used for detecting overpressure or low
pressure conditions inside the system, and if necessary to shut down the affected
system components in order to avoid system damage.
Overpressure
If the system pressure exceeds the adjustable switch-on value, an error message
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, the sys-
tem is switched on again.
Note:
For the overpressure monitoring function, the
switch-on value must be at
least 0.1 bar higher than the switch-off value. The adjustment ranges will
automatically adapt to that.
Low pressure (leakage)
If the system pressure falls below the adjustable switch-on value, an error message
will appear.
If the shutdown option has been activated for the low pressure monitoring function,
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, the system
is switched on again.
Note:
For the low pressure monitoring function, the switch-off value
must be at
least 0.1 bar higher than the switch-on value . The adjustment ranges will
automatically adapt to that.
