Sensor Connections
For operation with a 4-wire sensor,
cSEN to +EXC and -SEN to -EXC.
This can be achieved by installed jumpers at E5 and E6 on the circuit board, or by
making the connections externally at the J1 connector.
For operation with a 6-wire sensor,
cSEN to +EXC and -SEN to
–EXC at
the sensor. 6-wire operation allows the distance between the sensor and the signal
conditioner to be up to 1 km (3300 ft).
