4- or 8-Wire
sensor cable
Switches S1-1, S1-2, S1-3, and S1-4 establish the correct shunt calibration
connections for 4-wire and 8-wire sensor cables. The length of the sensor cable
determines which type of cable is used. Short cables are typically 4-wire cables
while long cables are typically 8-wire cables.
• Switches S1-1 and S1-2 select a 4- or 8-wire transducer for positive
feedback.
• Switches S1-3 and S1-4 select a 4- or 8-wire transducer for negative
feedback.
• The setting of jumper W8 (single ended excitation enable) may affect your
choices for these switches.
Note +/– excitation (–excitation is standard).
