GF Signet ProcessPro 8850-2 Installation Manual

Signet 8850-2 Conductivity/Resistivity Transmitter
*3-8850.090-2*
3-8850.090-2 Rev. J 4/12
CAUTION!
• Remove power to unit before wiring input
and output connections.
• Follow instructions carefully to avoid
personal injury.
1. Installation
ProcessPro transmitters are available in two styles: panel mount and fi eld mount. The panel mount is supplied with the necessary
hardware to install the transmitter. This manual includes complete panel mounting instructions.
Field mounting requires a separate mounting kit. The 3-8050 Universal kit (159 000 184) enables the transmitter to be installed
virtually anywhere. Detailed instructions for fi eld installation options are included with the 3-8050 Universal kit.
1.1 Panel Installation
1. The panel mount transmitter is designed for installation using a 1/4 DIN punch. For manual panel cutout, an adhesive template
is provided as an installation guide. Recommended clearance on all sides between instruments is 1 inch.
2. Place gasket on instrument, and install in panel.
3. Slide mounting bracket over back of instrument until quick-clips snap into latches on side of instrument.
4. To remove, secure instrument temporarily with tape from front or grip from rear of instrument. DO NOT RELEASE.
Press quick-clips outward and remove.
