• S
3
L devices may be connected to any available set of I/O terminals, or may be spliced into existing S
3
L device cable.
*Sensor may be connected to host instrument via pass-through S
3
L terminals on the 8059.
•
Only one wire should be inserted into a terminal. Splice double wires outside the terminal.
• The
TOTAL cable length from all S
3
L devices to the transmitter must not exceed 122 m (400 ft.).
•
Do not route I/O cables in conduit containing AC power wiring. Electrical noise may interfere with data signal.
•
Routing cable in grounded metal conduit will help prevent electrical noise and mechanical damage.
•
The sensor confi guration must be reset before the host instrument will recognize a new S
3
L device.
(see Calibrate menu, “Reset Sensor Confi guration” in the 8250 Level Transmitter manual.)
