Verify status and operation

Verify the status and operation of the CSI 9420 through the following:
  • LCD
  • Field Communicator
  • Smart Wireless Gateway


If the LCD is installed and enabled, it should display the measured values at the configured update rate during normal operation.

Remove the front cover of the LCD and press the DIAG button to display the Tag name, Device ID, Network ID, Network Join Status, and Device Status screens and make measurements.

The front electronics end cap (the cap covering the LCD) is certified for Class I, Division I in appropriate gas environments (check the nameplate on the device for details).

Exposing the electronics to a production environment may allow particulates, moisture, and other airborne chemicals to enter into the device, which could lead to contamination and potential product performance issues. In all cases, whenever opening the front end cap, be sure to seal it completely afterwards by tightening until the black O-ring is no longer visible.

Table 1 shows the LCD screens when the CSI 9420 connects to a network.

Field Communicator

You can verify the status of the CSI 9420 and configure it using a Field Communicator. Table Table 2 shows the fast key sequences you can use to configure and connect the CSI 9420 to a network. See the Configuration with a Field Communicator and Field Communicator fast key sequences for more information on the Field Communicator menu trees.

Note: HART Wireless transmitter communication requires a CSI 9420 Device Descriptor file (DD). The DD is included on the DVD that came with the device. Refer to the Field Communicator User's Manual for more details on DDs or go to for instructions on adding a DD for CSI 9420.

Note: The CSI 9420 does not publish any data to the gateway while a Field Communicator or HART modem is attached to it. After removing the leads from the Field Communicator/HART modem, the CSI 9420 senses that this connection has been removed and resumes publishing data to the gateway; however, this process can take several minutes. Pressing the "CONFIG" button on the local operator interface (when the CSI 9420 is not already engaged in performing another task) forces the CSI 9420 to switch operating modes.

Smart Wireless Gateway

From the Smart Wireless Gateway web server, navigate to the Explorer page. This page shows if the device has joined the network and if it is communicating properly.

The Explorer page displays the transmitter tag name, PV, SV, TV, QV, time of last update, and update rate (burst rate). A green status indicator means that the device is working properly. A red indicator means there is a problem with either the device or its communication path.

Note: It is normal for the CSI 9420 to have a red “X” on the screen until the sensor is installed.

Click on a tag name to display more information about the device.

If the CSI 9420 is configured with the Network ID and Join Key, and sufficient time for network polling has passed, the transmitter will then be connected to the network.

The most common cause of incorrect operation is that the Network ID or Join Key are not set correctly in the device. The Network ID and Join Key in the device must match those found on the Smart Wireless Gateway. From the Smart Wireless Gateway, click Setup > Network > Settings to display the Network ID and Join Key. Make sure the setting for "Show join key" is set to Yes.
