Please refer to „8.6 Grounding" on page 33
The following conditions apply "Table 5: Technical
data of PSk2 controller" on page 24
Connect a well probe or float switch to terminal
1+2 to protect the pump system from running dry.
Every pump system must be equipped with a dry run
protection. Connect a jumper wire between 1+2 if
not used.
Connect a tank switch, pressure switch or any other
suitable remote switch to terminal 3+4.
Connect a jumper between 3+4 if not used.
Connect water detection sensor for surface pumps –
for submersible pumps a jumper wire is needed
between 5+6.
Connect the SunSensor to terminal 7+8 and observe
polarity. The SunSensor is included with the PSk2
controller and needed to protect the pump.
