Other Helpful Features of LVCN-302

Interrupted 4-20 mA Signal from Sensor

Whenever the 4-20 mA signal from the sensor device is lost because of an open wire or device malfunction, an ERR3 message is displayed in the Actual Liquid Level window. Additionally, the entire bar display will flash red and green.

Over &/or Under 4-20 mA signal received

When the input sensor is sending a 4.0 mA signal, the Actual Liquid Level display will show a \/ character in the first digit of the display.

Actual Liquid Level

00.0

Process Signal

Input is 4.0 mA, but

not an open wire.

See above for open wire

Actual Liquid Level

00.0

Process Signal Input is 20.0 mA

Software Version Numbers

The version number of your LVCN-302 unit is shown in the Actual Liquid Level display window when you power up the unit. If your unit has version 2.8, you will see in the window LV 2.8

Programmed data cannot be lost

All the data and logic are written to a permanent EEPROM, which will retain your data in the event the power supply is disconnected. There is no battery on the board to maintain the data in the EEPROM.
