Pentair Pentek Solar Drive Sensor Settings
The Pentair Pentek Solar Drive controller can be turned ON or OFF remotely by using a
digital input or by using a standard float switch. There is a float switch terminal block
(Figure 6 on page 8) where digital signal wires are connected.
If Digital Inputs 1 and G experience a short circuit, the Pentair Pentek Solar Drive
automatically turns off. Similarly, if Digital Input 2 and G experience an open circuit, the
Pentair Pentek Solar Drive automatically turns off. There are numerous remote sensors
that can be used: float switch, pressure switch, flow switch, water level sensor, dry
run protection, etc. Ask your dealer about configuring sensors and switches for your
application.
A typical example of how tank and well switch signals can be used with a digital input port
is shown in Figure 10. For a tank application, if the active wire is connected to Position 1
and the return wire (usually black) is connected to Position G, then the Pentair Pentek Solar
Drive will stop the pump when the tank gets full because Terminals 1 and G will be “shorted”
(active short). This turns off the Pentair Pentek Solar Drive. See Figure 11.
For a well application, if the active wire is connected to Position 2 and the return wire
(usually black) is connected to Position G, then the Pentair Pentek Solar Drive will stop
the pump when the well runs out of water because Terminals 2 and G will be “open” (active
open). This turns off the Pentair Pentek Solar Drive.
