2.0 Installation & Operation 319R

The analysis unit should be installed in the process at a maximum distance of 6 feet away from the main unit, depending upon the level of electromagnetic noise in the operating environment.

Analysis Unit Connection

The receptacle for the analysis unit cable is located in the lower left- hand corner of the rear panel. The 6-pin Minifit fitting is keyed to fit only one way in the receptacle; do not force it in. The other end of the cable is made of four separate wires; these should be connected to the terminal strip on the analysis unit as follows:

Red:	#1
Black:	#2
Green:	#3}	The green and white connectors can be
White:	#4	interchanged, but be consistent.

Refer to the probe interconnection dwg. A-58154.

Sample flow and pressure should not create significant backpressure past the sensor; 2 SCFH (atmospheric pressure) is nominal.

AC Power (International Ranges)

A 6-foot power cord is supplied with the Model 319R. Plug the female end of the power cord into the receptacle in the upper left-hand corner of the rear panel. The unit is now ready to be plugged into an AC power source (85-264 VAC, 47-440 Hz).

The ON/OFF switch is located to the right of the power cord recep- tacle.

DC Power

If you have ordered the 10-36 VDC power option, install DC power via the terminal strip on the rear panel of the unit.

Output Signals

Terminals for 4-20 mA, 0-10 VDC, and range identification are labeled on the rear panel of the analyzer, along with high alarm, low alarm, and sensor failure block terminals.
