The VK86 connection cable has the following pin assignment:

To connect a sensor, lead its connecting wires into the box using one of the four cable

glands and connect them to the respective terminal of the terminal block.

When you connect the cable to the IN socket of the logger, make sure that the guide on

the plug fits in the groove in the socket and that you feel the plug latch in.

NOTE

When you install the measuring system please keep in mind that water and

dust can penetrate the box.
