5.- Entering the High Alarm Level Press the SELECT button again - the High Level Alarm Point indicator LED on the graphic face and the top RED line in the bar graph display will flash. P___ appears in the display. Enter the level, using the INCREASE or DECREASE arrow to set the desired level. When this point or level is reached, it will indicate a High Level Alarm has been reached and activate the control circuit/device you have designed into your system.

6.- Entering the Sump ON Level Press the SELECT button again - the yellow Sump ON indicator LED will flash along with the YELLOW line in the bar graph. P___ appears in the display. Enter the level, using the INCREASE or DECREASE arrow to set the desired Sump ON level. When this point or level is reached, LVCN-302 will deactivate the differential output relay to the control circuit/

device you have designed into your system.

7. - Entering the Sump OFF Level Press the SELECT button again - the Sump OFF indicator LED and the ORANGE line in the bar graph will flash. P___ appears in the display. Enter the Sump OFF level, using the INCREASE or DECREASE arrows. When this point or level is reached, LVCN-302 will activate the differential output(s) to the control circuit/device you have designed into your system.

8.- Entering the Low Alarm Level Press the SELECT button again - the Low Level Alarm Point indicator LED on the graphic face and the top RED line in the bar graph display will flash. P___ appears in the display. Enter the Low Alarm Level, using the INCREASE or DECREASE arrow. When this point or level is reached, it will indicate a Low Level Alarm has been reached and activate the control circuit/device you have designed into your system.
