2.2
CONNECTING A SENSOR
Attach the GK-404-1 flying leads to the bare leads of a
GEOKON
vibrating wire
sensor by connecting each of the clips on the leads to the matching colors of the
sensor conductors, with blue representing the bare shield wire.
GEOKON
makes patch cables that enable the GK-404 to read sensors with
connectors attached to the readout cable.
2.3
CONNECTING A LOAD CELL
If a load cell cable has a readout cable connector attached, the GK-404 can
easily connect to it using a patch cable provided by
GEOKON
.
If the load cell cable does not have a connector, the leads of the load cell may be
connected directly to the flying leads from the GK-404. The individual leads can
be identified as shown in the wiring diagram in Table 1 below.
Each sensor is read in turn by connecting either the red or black clip to the lead
marked
common
. The black or red clip must be connected to the leads marked
#1, #2, #3, etc. The blue clip should be connected to the cable shield wire, and
the green and white clips to the cable leads marked
thermistor
.

White's black and Green wires are switched on Geokon three gauge VW load cells prior to serial number 3313.
