Quick Start Guide
2.5 Wire sensor to transmitter
Procedure
1. Wire the correct sensor leads to the main board using the lead
locations marked directly on the board.
Use integral cable SMART sensors or compatible VP8 pH cables
to wire the Rosemount SMART pH sensors to the transmitter.
2. After wiring the sensor leads, use wiring diagrams found in
the sensor manual to guide you as you carefully take up the
excess sensor cable through the cable gland.
Keep sensor and output signal wiring separate from loop
power wiring. Do not run sensor and power wiring in the same
conduit or close together in a cable tray.
When wiring a pH/ORP sensor to the transmitter, follow this order:
1. Wire TB3/RTD to the return, sense, and RTD in terminals.
2. Wire TB2/reference and solution ground to the reference in,
reference shield, and solution ground terminals.
3. Wire TB4/preamplifier (if present) to the +volts and -volts
terminals.
4. Wire TB1/pH input to the pH shield and pH in terminals.
