The default update rate is eight seconds and will be appropriate for most applications. A more frequent update

August 2018

Quick Start Guide

rate may be used if desired. A less frequent update rate will extend transmitter power module life and optimize Wireless Gateway device capacity.

Consider the speed with which you want to be alerted to a dangerous concentration of toxic gas. “Reporting by exception” is not recommended for the Rosemount 928 Wireless Gas Monitors or Emerson Wireless Gateways due to its potential adverse effect on Wireless Gateway capacity and network integrity. Therefore, select an update rate for all Wireless Gas Monitors that corresponds to the safety needs of your facility but does not exceed the capacity of the Wireless Gateway or your wireless network.

Note

The LCD display and the optional local alarm output (if installed) update rates are not affected by the configured wireless update rate.

5.4 Configuring the update rate

The Rosemount™ 928 Wireless Gas Monitor takes measurements every two seconds. The update rate is the frequency at which new measurements and device status are transmitted over the wireless network. The update rate may be changed during configuration. The update rate range is 1 second to 60 minutes. The default update rate is eight seconds. Less frequent update rates help extend power module life and optimize Wireless Gateway capacity.

6.0 Calibrating the gas sensor module

Calibrating the Rosemount™ 628 Gas Sensor Module ensures that the analog, digital, and discrete outputs accurately transmit the target gas concentrations registered by the Rosemount 628 Gas Sensor Module. Although calibration was performed at the factory, the device must be calibrated at the following times to ensure accurate and correct operation:

 During installation

Quick Start Guide

August 2018

 At least every 90 days throughout the device’s service life  When replacing the Rosemount 628 Gas Sensor Module

The Rosemount 628 Gas Sensor Module is a smart sensor. As such, it retains its own calibration information. It must be connected to a Rosemount 928 Transmitter to perform calibration, but the calibration settings are stored in the sensor itself rather than in the Rosemount 928 Transmitter. The Rosemount 628 Gas Sensor Module may be uninstalled from a Rosemount 928 Transmitter and reinstalled in another without affecting its calibration.

Note

A conventional calibration cup is not required to calibrate the Rosemount 628 Gas Sensor Module. Connect calibration tubing (PVC tubing, 3/16-in. ID, 5/16-in. OD) directly to the fitting on the Rosemount 628 Gas Sensor Module IP filter assembly (00628-9000-0001).

8.0 Wireless considerations

8.1 Power up sequence

The Rosemount™ 928 Wireless Transmitter and all other wireless devices should be installed only after the Wireless Gateway has been installed and is functioning properly. Install the Emerson

™

701 SmartPower Module—Black into the Rosemount 928 Wireless Gas Monitor to power the device. Power up Wireless devices in order of proximity from the Gateway, beginning with the closest. This results in a simpler and faster network installation. Enable Active Advertising on the Gateway to ensure that new devices join the network faster. Refer to the reference manual for your Wireless Gateway for more information.

8.2 Antenna position

The antenna should be positioned vertically, either straight up or straight down and should be, if the application requirements allow, approximately 3 ft. (1 m) from any large structure, building, or conductive surface to allow for clear communication with other devices.

August 2018

Quick Start Guide

Figure 3. Antenna Position

8.3 Conduit entries

Upon installation, ensure that each conduit entry is either sealed with a conduit plug using appropriate thread sealant, or has a conduit fitting or cable gland installed with appropriate thread sealant.

Figure 4. Conduit Entries

A. Conduit entries

Quick Start Guide

August 2018

8.4 Choosing an installation location and position

When choosing an installation location and position, take into account access to the Rosemount

™

928 Transmitter for ease-of-use for the power module and Rosemount 628 Gas Sensor Module replacement. For best performance, the antenna should be vertical with space between objects in a parallel metal plane, such as a pipe or metal framework, as the pipes or framework may adversely affect the antenna’s performance.

The Rosemount 928 Wireless Gas Monitor is a diffusion-based gas monitor. This means that the target gas must actually come into contact with the electrochemical sensor for the device to register a signal. Each target gas has a unique density and will behave differently depending on the density of the surrounding atmosphere. For example, Hydrogen Sulfide is considered a heavier-than-air gas and tends to settle in low-lying areas when released into the air.

Install Rosemount 928 Wireless Gas Monitors with the sensor module facing downwards. Devices fitted with sensors for heavier-than-air target gases should be installed close to ground level, ideally between 12 in. above the ground and the breathing zone of a worker (3–6 ft. above grade level).

9.0 Electrical

9.1 Handling the power module

The Rosemount™ 928 Wireless Gas Monitor is self-powered. The included Emerson 701 SmartPower Module—Black contains two “C” size primary lithium/thionyl chloride batteries. Each battery contains approximately 2.5 grams of lithium, for a total of 5 grams in each pack. Under normal conditions, the battery materials are self-contained and are not reactive as long as the batteries and the power module are maintained. Take care to prevent thermal, electrical, or mechanical damage. Contacts should be protected to prevent premature discharge.

9.2 Making electrical connections (928XSS01 and 928XUT01 only)

See Figure 4. Make connections through the cable entry in the side of the connection head. Be sure to provide adequate clearance for cover removal.

Use caution when handling the power module

It may be damaged if dropped from heights in excess of 20 ft. (6.10 m).

August 2018

Quick Start Guide

10.0 Verifying operating atmosphere

Verify that the operating atmosphere of the Rosemount™ 928 Transmitter and the Rosemount 628 Gas Sensor Module is consistent with the appropriate hazardous locations certifications.

Table 1. Temperature Guidelines

Note

The electrochemical cells in sensor modules have a limited shelf life. Store sensor modules in a cool location that is not excessively humid or dry. Storing sensor modules for periods longer than three months may shorten their useful service life.
