equipment while a hole is drilled and a cable gland is
installed. The cable gland must accommodate the 0.40-
inch diameter ADS cable.
Connect the ADS cable. However, before beginning this
step, have the owner representative turn off the power to
the equipment and to any other connected devices that
may provide power through other means! There are two
“pairs” of the cable used for analog inputs. Input #1 (also
called channel #1) uses the red/black pair. Input #2 uses
the white/black pair. Black is always negative. Place these
wires in series with the signal wiring to become part of the
loop. The negative from the signal source usually connects
to the positive of the ADS cable. However, under some
conditions, these are reversed. No damage will occur if
these are connected backwards; however, the readings will
be negative. Reverse the connection if the readings are
negative or zero after checking the readings through
Diagnostics.
Note: Tape the ends of all unused wires in the ADS
cable to avoid shorting anything in the connection
area.
