Note

The Rosemount 6081 and all other wireless devices should be installed only after the 1420 Wireless Gateway has been installed and is functioning properly. Wireless devices should also be powered up in order of proximity from the 1420 Wireless Gateway, beginning with the closest. This will result in a simpler and faster network installation.

Note

Shipping considerations for wireless products (Power Modules):

The unit was shipped to you without the power module installed. Please remove the power modules from the unit prior to shipping.

Primary lithium power modules are regulated in transportation by the U. S. Department of Transportation, and are also covered by IATA (International Air Transport Association), ICAO (International Civil Aviation Organization), and ARD (European Ground Transportation of Dangerous Goods). It is the responsibility of the shipper to ensure compliance with these or any other local requirements. Please consult current regulations and requirements before shipping.

The power module with the wireless unit contains two “C” size primary lithium/thionyl chloride power sources.

Each power module contains approximately 5 grams in each pack. Under normal conditions, the power module materials are self-contained and are not reactive as long as the power modules and the pack integrity are maintained. Care should be taken to prevent thermal, electrical or mechanical damage. Contacts should be protected to prevent premature discharge.

Power module hazards remain when cells are discharged. Power modules should be stored in a clean and dry area. For maximum power module life, storage temperature should not exceed 30 °C.

WARNING

Use only with Rosemount Smart Power Module PN 701PBKKF

WARNING

Potential Electrostatic Hazard – The plastic antenna may present a potential electrostatic ignition hazard and must not be rubbed or cleaned with a dry cloth.

WARNING

Mechanical Spark Hazard – The 6081 enclosure is made of aluminum alloy and given a protective polyurethane paint finish.

However, care should be taken to protect it from impact or abrasion if located in Zone 0.

This applies to any Intrinsically Safe installation, whether the Class, Division or Zone system is used.

Quick Start Guide - 6081 Wireless pH Transmitter

1.Install the Power Module inside the rear enclosure. Follow the installation instructions on p.9 “Power Module Installation”.

2.Wire the pH or ORP sensor to the transmitter. Refer to the sensor instruction sheet for details.

3.Once the connections are secure and verified, install the Power Module to power to the transmitter.

4.When the transmitter is powered up for the first time, Quick Start screens appear. Using Quick Start is easy.

a.A blinking field shows the position of the cursor.

b.Use the or key to move the cursor left or right. Use the or key to move the cursor up or down or to increase or decrease the value of a digit. Use the or key to move the decimal point.

c.Press ENTER to store a setting. Press EXIT to leave without storing changes. Pressing EXIT also returns the display to the previous screen.

5.Choose a local language.

6.Choose measurement: pH, ORP, or Redox.

7.Choose preamplifier location. Select Xmtr to use the integral preamplifier in the transmitter.

8.Choose Off or On for displayed diagnostics.

9.Select measurement update rate. Select ENTER to choose an update rate of 1 minute or enter a value from 1 second to

10 minutes.

10.Choose temperature units: °C or °F

11.Choose Yes to Setup the Wireless Network or No if the Network ID and the Join Key have already been entered.

12.Enter the 5-digit Wireless Network ID. This ID number must match the Network ID of the 1420 Wireless Gateway.

13.Enter the 8-digit Network Join Key number 1 of 4 to match the 1420 Wireless Gateway. See the Note below for clarification.

14.Enter Network Join Key numbers 2, 3, and 4 to match the 1420 Wireless Gateway.

15.The transmitter will exit Quick Start and display the live measurement screen.

16.To change the Network ID or Join Key, HART address, or measurement-related settings from the default values, and to set security codes, press MENU. Select Program and follow the prompts. Refer to the appropriate menu tree.

17.To return the transmitter to default settings, choose Reset Analyzer in the Program menu.

Note regarding Wireless Device Configuration

In order to communicate with the 1420 Wireless Gateway, and ultimately the Information System, the transmitter must be configured to communicate with the wireless network. This step is the wireless equivalent of connecting wires from a transmitter to the information system.

Using a Field Communicator or AMS, enter the Network ID and Join Key so that they match the Network ID and Join Key of the gateway and other devices in the network. The Network Join Key consists of four (4) blocks, each with an eight digit code. The code of each block must match its corresponding block in the 1420 in order for the 6081 to join the network.

If the Network ID and Join Key are not identical, the transmitter will not communicate with the network. The Network ID and Join Key may be obtained from the 1420 Wireless Gateway on the Setup>Network>Settings page on the web server.

The final device network configuration piece is the Update Rate. This by default is one (1) minute. This may be changed at commissioning, or at any time via AMS or the 1420 Wireless Gateway’s web server. The Update Rate should be between 1 second and 10 minutes.

When device configuration is completed, remove the power module and replace the rear cover of the transmitter until the time of actual live installation in the process. Tighten the cover to the proper tension for safety approvals.

Note

For installation and operation at high elevations, slight convex bulging of the front keypad overlay is possible. If bulging occurs, it is recommended to unscrew the two Philips head screws that faster the front cover to the central housing to release any internal pressure. This will equalize the device’s internal pressure to the ambient atmospheric pressure. Re-tighten the two Philips head screws to secure the front cover before device installation or operation. Make sure to perform the pressure equalization in a clean, dry area.

Calibrations/standardization: The automatic buffer recognition uses stored buffer values and their temperature curves for the most common buffer standards available worldwide. The transmitter also performs a stabilization check on the sensor in each buffer.

A manual two-point calibration is made by immersing the sensor in two different buffer solutions and entering the pH values. The microprocessor automatically calculates the slope which is used for self-diagnostics. An error message will be displayed if the pH sensor is faulty. This slope can be read on the display and/or manually adjusted if desired. An online one-point process standardization is accomplished by entering the pH or ORP value of a grab sample.

The following calibration methods are supported:

-Two point calibration with Low and High buffer (pH only)

-Two point calibration with Automatic Buffer recognition (pH only)

-Single point standardization

-Single point Temperature Adjustment

-Automatic calibration upon live connection to RAI SMART pH sensors and upload of stored cal data to transmitter

Automatic Temperature Compensation: External 3-wire Pt100 RTD or Pt1000 RTD located in the sensor, compensates

the pH reading for temperature fluctuations. Compensation covers the range -10 to 150 °C (14 to 302 °F). Manual

temperature compensation is also selectable.

Accuracy: ±1 mV @ 25 °C ±0.01 pH

Repeatability: ±1 mV @ 25 °C ±0.01 pH
