9 Pump Accessories Installation
CAUTIONTo avoid multiple starts of
the pump in twilight conditions, the Sun
Sensor module must be installed and
configured for all PS2-1800 CS-F and all
PS2-4000 pump systems. Operating
without a Sun Sensor module can lead to
increased wear or damage to the pump.
Such damage is excluded from the
warranty.
CAUTION – Never let the pump run dry.
Dry running will damage the pump and
void the warranty. LORENTZ requires a dry
run protection for every pump system.
CAUTION – Installing a surge protector
at all switch inputs is recommended,
damaged inputs due to electric surges are
not covered by the warranty.
Figure 21: Well probe fixing
9.1 Well Probe
The well probe contains a mechanical float with a magnet
inside. When the probe is submerged, the float rises, and the
magnet actuates a switch. The switch closes (makes contact)
to indicate the presence of water. If the water level drops
below the probe, the float drops, and the switch opens
(breaks contact): The controller will stop the pump. When
the water level recovers and the switch closes again, the
controller will delay the restart for 15 minutes for the water
level to recover. To force a quick restart, turn the controller
off, then on again. The switch is sealed, so the contacts
never touch the water.
Submersion depth – The maximum submersion depth is
50 meters.
Fixing – Along with the probe two cable ties are provided.
For a pump that is to be installed in a vertical position,
clamp the probe to the pipe just above the pump outlet,
as shown in “Figure 21: Well probe fixing”. Splice the two
wires of the probe using the splice kit components that are
packed with the probe. The assembly procedure is the same
as the main pump splice.
Wiring to the controllerThe well probe must be wired
to the controller at terminal 1 and 2, cf. “7.6.3 Pump Acces-
sories Wiring” on page 27.
Potential problems with the well probe in surface
waterThe probe has a moving float. It is highly resistant
to deposits and debris. However, the float can become stuck
where algae or water creatures are present in surface water..
