2.3 SIGNAL WIRING
The Dura-Trac and Dura-Trac II Sensors transmit the sensing signal to
Monitor/Controller by a multi conductor wires, see Figure 7 for signal wires
interconnection diagram. Twisted shielded cable should be used. The cable should be
enclosed in conduit for maximum protection against damage or electrical interference.
Do not run cable in same conduit with any other wiring.
CAUTIONS
R Make sure the monitor’s power switch is turn to off position before making any
signal wiring connections.
