4.2.3 Enable / Disable channels

This option allows the Millennium II Transmitter channels to be enabled or disabled. The default value is channel 1(CH1) enabled for single sensor models while channel 2(CH2) is permanently disabled. Both channels are enabled for two sensor models.

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

2.Select the down arrow key (switch 2) with the magnet, and scroll to “Enable/Disable Channel?”

3.Activate the enter key (switch 3) to enter the option. The sub menu options: ‘CH 1 Enabled’ and ‘CH 2 Enabled’ will be highlighted.

4.To disable a channel 1, Activate the enter key (switch 3). “CH1 disabled” will now be highlighted / displayed.

5.To disable channel 2, highlight ‘CH2 Enabled’ use switch 2, then activate the enter key (switch 3) to configure to

‘CH2 disabled’.

6.To exit the main menu, select “Exit” with enter key at each menu stage (sub menu and main menu).

4.2.4 Viewing and setting alarm levels (points)

This option enables the channel low and high alarm levels to be viewed and set-up. Alarm levels (points) for each channel are user determined. Alarm Point 1 and Point 2 for channel 1 does not relate to Alarm Point 1 and Point 2 for channel 2.

1.Enter the main menu by selecting/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 the down key (switch 2) until “Set Alarm Level?” is highlighted / displayed.

3.Activate switch 3 to enter the “Set Alarm Level” option. Sub menu options ‘Set CH1 Level’, ‘Set CH2 Level’ and ‘Exit’ will be displayed. ‘Set CH1 Level’ being highlighted.

4.To view channel 1 alarm points, activate switch 3. ‘CH1 Point 1’ and ‘CH1 Point 2’ will be displayed.

5.To view channel 2 alarm points use switch 2, at step 3, highlight ‘Set CH2 Level’, then activate switch 3. ‘CH2 Point 1’ and ‘CH2 Point 2’ will be displayed.

6.To configure channel 1 alarm levels (Point 1 or Point 2), after step 4, use switch 3 to select CH 1 Point 1 (already highlighted) then proceed to step 8, or highlight CH1 Point 2 using switch 2 , then activate switch 3 and proceed to step 8.

7.To configure channel 2 alarm levels (Point 1 or Point 2), after step 5, use switch 3 to select CH2 Point 1 then proceed to step 8, or use switch 2 to highlight CH2 Point 2, then activate switch 3 to make a selection. Proceed to step 8.

8.Use switch 1 to increase the existing values representing previously set alarm levels/points and switch 2 to highlight and scroll across values.

9.After setting desired alarm points, select “Exit” at each menu stage (sub menu and main menu).
