Setting low pressure detection on suction
(typically used in boosting systemsconnected to the water mains)
The low pressure detecting function generates the blocking of the system after the time T1 (see T1: Low pressure delay :).
When this function is active the symbol F4 is shown on the main page.
Tripping of this function causes the pump to cut out; it may be reset automatically or manually. The automatic reset requires that, to
leave the error condition F4, the pressure must return to a value 0.3 bar higher than PK for at least 2 sec. To reset the cut-out in manual
