Note 1: In above example, alarm relay 3 (RL3) will trigger whenever any alarm level 2(point 2) is reached.

Note 2: For the single channel relay model transmitter, all (3) alarm relays are available for channel 1.

4.2.7 Relay Alarm Mode setting (for Oxygen sensors only)

This option is available for detecting oxygen levels. The user is allowed to set up two Alarm points/level (normal oxygen level is 20.9 %) under three available Alarm Modes. These Alarm Modes are: Above-Above, Below-Below and Below-Above. The Alarm Mode chosen by the user depends on the particular application/operation. If surrounding air is to be used for calibration, ensure that no contaminants are present. Refer to the Oxygen Sensor

Manual (MAN-0093) for detailed information.

4.2.8 Select Display Language

This option allows the display language to be selected. The default language is English. There are also options for Spanish, French, and Portuguese.

1.Enter the main menu by activating any key to get the “enter main menu” prompt then activate switch 1 to select “yes”.

2.Activate the up key (switch 1) or down key (switch 2) until “Select Display Language?” is displayed.

3.Activate the enter key (switch 3). The default language, ‘English’, will be displayed.

4.Locate other languages by activating the enter key (switch 3).

5.Once the desired language is displayed, select “Exit” at each menu stage (sub menu and main menu).

4.2.9MODBUS Setup

This option enables the following MODBUS parameters to be set:

•Addressing: From 001 (default) to 247

•Baud Rate: 02400 bps, 04800 bps, 09600 bps (default), 19200 bps, and 57600 bps.

•Frame Format: EVEN Parity (default), ODD Parity, NO Parity.

1.Enter the main menu by activating any key to get the “enter main menu” prompt, then activate switch 1 to select “yes”.

2.Select the up arrow key (switch 1) or down arrow key (switch 2) until “Modbus Setup” option is displayed.
