Emerson Process Management 3081 pH/ORP specification

MODEL 3081 pH/ORP	SECTION 3.0
	WIRING

REMOVE BNC AND TERMINATE COAXIAL CABLE BEFORE WIRING SENSOR TO TRANSMITTER. SEE FIGURE 3-23. ALTERNATIVELY, USE A BNC ADAPTER (PN 9120531) OR ORDER MODEL OPTION -62 (SENSOR WITH BNC REMOVED AND TER- MINATIONS COMPATIBLE WITH 3081 pH/ORP). IF USING A BNC ADAPTER, THE RED WIRE IS MV OR pH IN AND THE BLACK WIRE IS REFERENCE IN. TO PREVENT SHORT CIRCUITS TO THE TRANSMITTER HOUSING, INSULATE THE BNC WITH BY WRAPPING IT WITH ELECTRICAL TAPE.

IF USING A BNC ADAPTER, THE RED WIRE IS MV OR pH IN AND THE BLACK WIRE IS REFERENCE IN. TO PREVENT SHORT CIRCUITS TO THE TRANSMITTER HOUS- ING, INSULATE THE BNC WITH BY WRAPPING IT WITH ELECTRICAL TAPE.

FIGURE 3-3. Wire functions for Models 399-02, 399-09, 381pH-30-41, and 381pHE-31-41 after removing BNC and terminating cable. Wire functions for Models 399-09-10-62, 381pH-30-42 and 381pHE-31-42 as received.

NOTES:

1.PLACE PREAMPLIFIER SELECTION SWITCH S1 IN "TRANSMITTER" POSITION (SEE SECTION 2.2).

2.IF SENSOR HAS 3K BALCO RTD, SET JUMPER (SECTION 2.2) AND PROGRAM TRANSMITTER TO RECOGNIZE RTD (SECTION 8.5-pH OR 10.5-ORP)
