FIGURE 3-6. Wiring for Sensors Without Solution Grounds Directly to Analyzer (Models 389-02-54,
396-54, 397-54, 399-09). For wiring to a junction box, see Figure 3-7.
FIGURE 3-7. Wiring for Sensors Without Solution Grounds to a Junction Box (Models 389-02-54, 396-54, 399-09)
NOTES:
1.Interconnecting wire maximum length is 500 ft. Use PN 9200273 (no substitutes). Shields must be insulated from each other at all cable ends. Connect to junction box as shown.
2.If distance to controller is short, the junction box is not required. Connect sensor leads directly to controller.
3.6 FINAL ELECTRICAL CHECK
When all wiring is completed, apply power to the con- troller. Observe the controller for any questionable behavior and remove power if you see a problem. With the pH sensor in the process, the display will show a pH value (though it may not be accurate).
CAUTION
To prevent unwanted chemical feed into the process and to prevent injury to operating personnel, disconnect the chemical feed pump and other external devices until the controller is checked out, programmed, and calibrated.
