STEP 1: PHYSICAL INSTALLATION

The CSI 9420 and all other wireless devices should be installed only after the 1420 Wireless
Gateway has been installed and is functioning properly.

Powering the CSI 9420

Remove the rear cover of the device to access the power connections. For the battery
powered version, simply plug in the power module. For the externally powered version,
connect a 10...28V DC (24V nominal) power supply to the bottom two screw terminals on
the right (see Figure 3). Pull the wiring through the threaded conduit entry. When selecting
the power supply, note that each CSI 9420 has a peak current draw of 40 mA when awake
and powering sensors.

NOTE:

Wireless devices should be powered up in order of proximity to the 1420 Wireless
Gateway, beginning with the closest device to the 1420. This will result in a simpler
and faster network installation.

GENERAL SENSOR HANDLING INSTRUCTIONS

The CSI 9420 utilizes special low-power sensors available from Emerson. Each sensor
requires a standard 1/4” - 28 mounting location. Refer to the User’s Manual for detailed
sensor mounting instructions. Sensor mounting instructions and practices are also available
in a separate Sensor Installation Guide on the CD packaged with this device and at
www.mhm.assetweb.com.

To maintain mechanical isolation of the sensor, a Remote Mount configuration is required,
as illustrated in Figure 2. In this configuration, the sensor is mounted separately from the
CSI 9420 housing, then connected to the CSI 9420. Although not required for all
installations, it is common to run the cable from the sensor to the housing through conduit.

NOTE:

The word “sensor” applies to both an accelerometer and an accelerometer with
embedded temperature. The word “accelerometer” refers to a sensor that measures
only acceleration.

Remote Mount

1. Install sensor or accelerometers according to standard sensor installation practices. Be
sure to use thread sealant on all connections.

2. Run wiring (and conduit if necessary) from the sensor to the CSI 9420.

3. Pull the wiring through the threaded conduit entry of the CSI 9420. If not using conduit,
an appropriate grommet or cable-gland should be used to provide both strain relief for
the cable and environmental isolation for the CSI 9420.

4. Attach the sensor wiring to the terminals as indicated in tables 1-3.

5. Connect the power pack module or external 24V DC power supply.

6. Close the housing cover and tighten to safety specification. Always ensure a proper seal
by installing the electronics housing covers so that metal touches metal, but do not over

STEP 2: VERIFY OPERATION

Operation can be verified by four methods: Viewing the LCD screen on the device, using the
375/475 Field Communicator, using the 1420 Wireless Gateway’s integrated web server, or
using AMS

™

Suite: Intelligent Device Manager (or other compatible HART-enabled host).

Refer to Step 3: Communications and Configuration for details regarding each method.

If the LCD is installed and enabled, during normal operation, the LCD displays the measured
values at the configured update rate. Every time the CSI 9420 device wakes up to make a
measurement it displays these screens and then takes the measurement. Refer to the CSI
9420 User’s Manual for error codes and other LCD messages.

Press the Diagnostic (DIAG) button once and the CSI 9420 will cycle through display of the
T AG, Device ID, Network ID, Network Join Status and Device Status screens, then make
a measurement. Pressing the DIAG button causes this information to be displayed even if
the LCD is disabled for normal operation.

NOTE: To access the DIAG button, remove the front cover of the CSI 9420.

The Network join status as displayed on the LCD is shown in Figures 4 for the 2.4 GHz and
Figure 5 for the 900 MHz versions. Prior to configuring the device to join a network, it will
remain in the Network Search mode.

STEP 3: COMMUNICATION AND CONFIGURATION

375/475 Field Communicator

In order to communicate with a 375 or 475 Field Communicator, the CSI 9420 device must
be powered by connecting the power module pack, or connecting external 24V DC power.
Also, the initial boot and acquisition cycle must be complete (This is indicated when the LCD
screen goes blank after a number of messages are displayed). If no LCD is installed, or if
the LCD is disabled, wait about 30 seconds after powering the device before attempting to
communicate on the wired interface.

To use the 375/475 Field Communicator with the rev 3 CSI 9420, a rev 3 DD (Device
Description file) is required. The rev 3 DD for the CSI 9420 is located on the CD that is
shipped with the CSI 9420. 375/475 System Software version 3.2 or later is also required.

Refer to Figure 6 for an illustration of connecting the 375/475 to the CSI 9420. The wired
HART connection is located on the terminal block in the rear chamber of the device. It is a
two-wire, polarity-independent connection. In the battery powered version, it is the bottom
two terminals, labeled “COMM”. In the externally powered version, it is the top two screws
on the right.

NOTE

Refer to the 375/475 Users’ Manual for details on DD’s or go to
www.fieldcommunicator.com/syssoftdds.htm for instructions on adding a DD for the
CSI 9420 or other new devices.

AMS™ Suite: Intelligent Device Manager

When the device has joined the network, it will appear in AMS Device Manager as illustrated
in Figure 8. Note that it is necessary to rebuild the hierarchy before the new device appears
in the tree. Once the device has appeared in the 1420 wireless gateway’s web interface,
right click on the network node in Device Manager and choose Rebuild and Identify
Hierarchy.

Prior to joining the CSI 9420 to the wireless network, it is also possible to configure the
network settings from AMS Device Manager using a wired HART modem. The
drag-and-drop feature in AMS Device Manager allows automated joining of a wireless
device to an existing network using a wired HART modem. A “Scan Device” must first be
performed on the 1420 and the CSI 9420 device before the drag-and-drop operation is
performed.

Once the new device appears under the HART modem tree, drag the device over the
wireless gateway icon and release it. This automatically sets the Network ID and Join Key
and causes the device to join the network when it is in range. Refer to the AMS Device
Manager documentation for additional details.

Figure 8. AMS Suite: Intelligent Device Manager

Troubleshooting

The most common cause of network problems is that the Network ID and Join Key are not
set correctly. The Network ID and Join Key in the device must match that of the 1420
Wireless Gateway exactly.

The Network ID and Join Key may be obtained from the 1420 on the Setup > Network >
Settings page of the web server (see Figure 7: 1420 Network Settings). The Network ID
and Join Key may be changed in the wireless device with the 375/475 Field Communicator
by using the Fast Key sequences shown in Table 8 and Table 9.

PRODUCT CERTIFICATIONS

The CSI 9420 has a number of certifications and approvals including CE, FCC, R&TTE, FM,
CSA, and ATEX. Please refer to the User’s Manual for a complete list of product
certifications. The User’s Manual is included on the CD that ships with the device or it may
be downloaded from the web at www.mhm.assetweb.com. A printed copy of the User’s
Manual (MHM-97408) may be ordered by contacting your local sales representative, or it
can be printed out from the CD.

OPERATING LIMITS

Each of the CSI 9420 signal inputs uses accelerometers to make vibration measurements.
Alternately, an accelerometer with embedded temperature may be used. The operational
ranges for the sensors are shown in Table 10:

Table 10. Sensor ranges

The accelerometers require a DC bias. The CSI 9420 device provides the necessary bias
and measures it to verify correct sensor operation. The nominal bias voltage is 2.5 volts. If
the bias voltage is outside of the 2 - 3 volt range, the device generates a FAILED alert for the
associated accelerometer. The DC input range represents the operational DC range of the
signal input. The AC input range represents the operational AC range of the signal input.
