9 4 5 Solar panel for Sun Switch
WARNING – To avoid multiple starts of
the pump in twilight conditions, the
SunSwitch must be installed and
configured according to COMPASS
data Multiple starts due to an
incorrectly configured SunSwitch can
lead to increased wear and damage
the pump Such damage is excluded
from the warranty
The PSk2 controller is supplied with a special small 1.5 Wp
PV module (pre-wired for crimping). This PV module is
used to measure the solar irradiation and allows you to set
irradiation dependent START / STOP values for the pump.
These settings can only be done via LORENTZ Pump-
Scanner. (Please check LORENTZ partnerNET and the "PS
DataModule and PumpScanner" manual).
WARNING – Do NOT use any other PV
module than the one supplied or the
PSk2 controller may be damaged
Mount the PV module with the same alignment as the
solar array that powers the pump system. For example, if
the solar array is tilted at an angle of 20°, the PV panel for
the Sun Switch should be tiled exactly the same. You can
ensure this by mounting the PV module on the frame of the
PV module array.
The plug of the small solar panel for Sun Switch has a red
(positive +) and a black (negative –) cable. Take care of
correct polarity. The plug has a plastic pin that fits into a
groove in the socket for the plug. This ensures correct plug
installation.
WARNING – Voltage reversal of the
Sun Switch panel will lead to damage
of the controller
If you need to switch external units ON/OFF, e.g. a genset,
use external Sun Switch (see partnerNET under "Products"
– "Manuals" – "Accessories").
