Emerson 1066 Liquid Analysis Fieldbus pH/ORP Transmitter

Features and Applications

The Model 1066 Fieldbus Transmitter supports continuous measurement of one liquid analysis input.

It is designed for easy internal access and wiring connections.

Analytical inputs: pH and ORP sensors with or without Rosemount Analytical preamplifiers, and Rosemount Analytical smart pH sensors.

Large Display: High-contrast LCD displays real-time measurement readings in large numbers and up to four additional variables or diagnostic parameters.

Digital Communications: Fieldbus ITK 6 Menus: Menu screens for calibration and programming are simple and intuitive. Plain language prompts and "help" screens guide the user through the steps.

All menu screens are available in eight languages. Real-time process values are displayed during programming and calibration.

Troubleshooting and Warning Help Screens: Troubleshooting and warning information is included in the Help screens to provide the user with helpful troubleshooting tips. These screen instructions are intuitive and easy to use.

Diagnostics: The transmitter continuously monitors itself and the sensors for problems. On-screen display banners alert technicians to faults and/or warning conditions.

Languages: Emerson extends its global reach by offering eight languages: English, French, German, Italian, Spanish, Portuguese, Chinese, and Russian.

Input Damping: Automatically enabled to suppress noisy process readings.

Smart Enable pH: Rosemount Analytical SMART pH feature eliminates the need for field calibration of pH probes by automatically uploading calibration data and history.

Automatic Temperature Compensation: pH measurements require temperature compensation. the 1066 will automatically recognize the sensor's built-in Pt100 or Pt1000 RTD, or the temperature of an on-bus temperature measurement can be linked to the 1066 and used for temperature compensation.

Sensor Wiring

Overview

Connect the correct sensor leads to the main board according to the lead locations labeled directly on the main board.

Rosemount Analytical SMART pH sensors can be connected to the 1066 using either the integrated cable SMART sensor or a compatible VP8 pH cable.

After completing the wiring of the sensor leads, carefully route the excess sensor cable through the cable gland.

Separate the sensor and output signal wiring from the loop power wiring. Do not place the sensor and power wires in the same conduit or near a cable bridge.

Sensor Wiring Details

Sensor wiring should be done in the order shown above. The terminals are listed below:

TB3 RTD INPUT TERMINALS: The leads of the 3-wire RTD should be wired as shown. If a 2-wire RTD is used, the RTD return and RTD sense terminals must be jumpered to avoid an open RTD sense wire warning.

TB2 Reference Electrode and Solution Ground: The reference electrode lead and its shield and the solution ground lead should be grounded as shown. If the sensor does not have a solution ground, there are two options:

1. The reference voltage input and solution ground can be jumpered. If this is done, the reference impedance will read a constant value of 0 kilohms.

2. The second method is to turn on the solution ground terminal and set the Reference Impedance parameter (Reference Z) in the program menu (see Section 7.3.7) to High, 

thus turning off the reference impedance measurement. If the solution ground terminal is left open without doing so, a high reference impedance fault alarm will continue to sound.

TB4 Preamplifier Power: The power wire from the pH sensor or preamplifier in the junction box is connected to this terminal to supply power to the preamplifier.

TB1 pH Electrode Input: The pH electrode lead and its shield are located on this terminal as shown.

Smart pH Sensor: The smart pH sensor has a ground wire (not to be confused with the solution ground wire) that should be connected to the enclosure ground as shown in the power wiring diagram.
