NOTE: Connecting sensors to the back terminals first may be easier in terms of installation. Sequence:
(9-12, 7-8, 15, 4-6, 1-3, 13-14).
Connect sensor wires to the field wiring panel according to the Sensor Connections diagram
(see below)
using the following sequence:
1.
Touch the shield wire to the ground stud, and then connect it to the SHD (shield) terminal.
2.
Connect the black wire of the sensor to the “GND” terminal of the appropriate channel’s input.
3.
Connect the signal (white or clear) wire to the “SIG” (signal input) terminal.
4.
For three terminal devices ONLY (such as vanes or anemometers requiring 12 V power), connect
the red wire (excitation/power) to the “EXC” terminal.
5.
Confirm correct wiring by reviewing each sensor channel on the logger’s display.
6.
Coat the wiring panel’s terminal screws with an anti-corrosive product (such as PreserveIT P100L
from Caig Labs or Vaseline petroleum jelly).
7.
Systems that include an iPack will be on as soon as the iPack is connected and supplying power
to the logger. For systems without an iPack, install the D-cells now as described in the Logger
Setup section of this manual.
