6.2 LED indicator and fl ow switch
The fl ow switch cannot be adjusted or switched,
it is fully automatic. There are only 3 LEDs which
indicate its operating status. (Figure 4)
Green and yellow are lit:
The pump is in operation and starts up immedia-
tely; a consumer for drawing off transport fl uid is
open.
Green and red are lit:
1. The pump is building up pressure (e.g. a
water tap is closed) and then switches off au-
tomatically.
2. The pump is running dry without transport
fl uid. The fl ow switch will make 3 attempts to
eliminate the dry running before the dry run-
ning guard fi nally trips.
Green is lit, red is fl ashing:
The dry running guard has tripped; it is no longer
possible to draw in the transport fl uid. Use the
pump's operating manual to fi nd the cause of the
fault (e.g. a leaking intake line) and rectify it. Then
restart the pump by pressing the Reset button on
the fl ow switch.
