7.2 Operating modes
7.2.1 Manual mode
Manual mode is reserved for emergencies. Continuous manual operation would lead
to waste of energy and water and cause the fluid handled and/or the pump set to
overheat. A manual-automatic selector switch is provided at the switchgear and
controlgear assembly. When the switch is set to
manual the pump set is operated on
the power supply network, independently of the automatic system (pressure switch).
7.2.2 Functional check run
The switchgear and controlgear assembly contains a timer. During the functional
check run the pump set is operated directly on the power supply network,
independently of the automatic system (pressure switch). The functional check run
parameters can be set via the timer (see supplied original operating manual).
7.3 Functions
7.3.1 Dry running protection
A digital input is provided for connecting dry running protection equipment. When
the input is open, the control unit detects dry running and stops the pressure booster
system after approx. 10 seconds (factory setting).
