10.10 Check sensor-to-transmitter wiring
A number of power-supply and output problems may occur if the wiring between the
sensor and the transmitter is improperly connected, or if the wiring becomes damaged.
Be sure to check all wiring segments:
• If you have a 4-wire transmitter, check the wiring between the transmitter and the
core processor.
• If you have a 9-wire transmitter, check the wiring between the transmitter and the
sensor junction box.
• If you have a remote transmitter with remote core processor, check the wiring
between the transmitter and the core processor and the wiring between the core
processor and the sensor junction box.
