11.7.50 Pumps outside duty range (4.4.7)
Fig. 95 Pumps outside duty range
Description
The function gives a warning if the duty point of the pumps moves
outside the defined range. For instance, if the inlet pressure
becomes lower than a minimum permissible value, thus causing a
risk of cavitation for some pump types.
The warning is given with a set time delay. It is possible to set
whether the warning is to be reset automatically or manually
when the duty point comes within the defined duty range. It is
also possible to set a relay output to be activated when the
warning is given, and to be deactivated when the warning is
reset.
This function requires that the discharge pressure and the inlet
pressure (either measured or configured) or the differential
pressure of the pumps is monitored, and that CU 351 contains
valid pump data from either a GSC file or from manual input.
See section 11.7.37 Pump curve data (4.3.19).
