Model 6081-P

Wireless pH/ORP Transmitter

ESSENTIAL INSTRUCTIONS

READ THIS PAGE BEFORE PROCEEDING!

Rosemount Analytical designs, manufactures, and tests its products to meet many national and international standards. Because these instruments are sophisticated technical products, you must properly install, use, and maintain them to ensure they continue to operate within their normal specifications. The following instructions must be adhered to and integrated into your safety program when installing, using, and maintaining Rosemount Analytical products. Failure to follow the proper instructions may cause any one of the following situations to occur: Loss of life; personal injury; property damage; damage to this instrument; and warranty invalidation.

Read all instructions prior to installing, operating, and servicing the product. If this Instruction Manual is not the correct manual, telephone 1-800-654-7768and the requested manual will be provided. Save this Instruction Manual for future reference.

If you do not understand any of the instructions, contact your Rosemount representative for clarification.

Follow all warnings, cautions, and instructions marked on and supplied with the product.

Inform and educate your personnel in the proper installation, operation, and maintenance of the product.

Install your equipment as specified in the Installation Instructions of the appropriate Instruction Manual and per applicable local and national codes. Connect all products to the proper electrical and pressure sources.

To ensure proper performance, use qualified personnel to install, operate, update, program, and maintain the product.

When replacement parts are required, ensure that qualified people use replacement parts specified by Rosemount. Unauthorized parts and procedures can affect the product’s performance and place the safe operation of your process at risk. Look alike substitutions may result in fire, electrical hazards, or improper operation.

Ensure that all equipment doors are closed and protective covers are in place, except when maintenance is being performed by qualified persons, to prevent electrical shock and personal injury.

NOTICE

The Rosemount Model 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.

NOTICE

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-containedand 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.

CAUTION

If a Model 375 Universal Hart® Communicator is used with these transmitters, the software within the Model 375 may require modification. If a software modification is required, please contact your local Emerson Process Management Service Group or National Response Center at1-800-654-7768.

QUICK START GUIDE

FOR MODEL 6081 WIRELESS pH TRANSMITTER

1. Refer to Section 2.0 Installation for installation instructions.

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-digitWirelessNetwork ID. This ID number must match the Network ID of the Model 1420 Wireless Gateway.

13.Enter the 8-digitNetworkJoin Key number1 of 4 to match the Model 1420 Wireless Gateway. See the Note below for clarification.

14.Enter Network Join Key numbers 2, 3, and 4 to match the Model 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-relatedsettings 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.
