Sensor cable connections must be crimped and
SOLDERED
for stable operation. Use
only continuous, un-spliced cable runs if possible. Improperly spliced cable can result in
corrosion, resistance changes, and drift.
To connect the cable at the sensor:
1. Remove the P/N 10252-1 housing lid to reveal the terminal strip. The sensor is
connected in the housing according to the color designations (Figure 3). The
green position is not used.
2. Sensor cables are connected at the controller to the terminal blocks located
along the top of the rear of the controller. The channel numbers (1&2) read from
top to bottom on this terminal.
3. Connect the cable so that the terminal color at the sensor housing matches the
terminal color at the controller as follows (Figure 4):

of 40-Ohms):
