Gauge Configuration.

To Calibrate the Gauge, Open the front cover 4 screws, Connect the Tank Probe, and Power the unit.

Toggle the Calibration switch, located top right of the C2020 PCB, marked

Cal (LK2)

1. First screen to show is a “Cube” Tank.

The middle Button scrolls through the

Tank Type Options.

2. Use the “Hidden” Button to scroll

through

the settings.

3. Choose the feature you require, then set the values by using the “Hidden” Button to

select the value to change, then use the other two buttons to Decrease (LEFT) or Increase

(RIGHT) the value.

HIDDEN BUTTON

6. Now use the Right Button to scroll across to the Sensor Selection. This should be

Automatic.

If the Automatic does not work, scroll to Mode, and manually select type of sensor with

the Right Button.

7. Sensor Offset.

How far from the bottom of the tank is

the sensor positioned? Enter this here.

As standard we would recommend

50mm which is 0.050m.

Sensor Span. As Standard, this comes

set for 2.55m. Change this to suit the

sensor range you have. Curser Confirm

YES.

8. Toggle the Calibration switch.

The Gauge returns to Standard

Readings.

4. You MUST scroll YES and use the

“Hidden” Button to confirm YES for all

screens

5. Now use the Right Button to scroll

across to Alarm Trigger Points and

Specific Gravity settings.

High Accuracy Calibration Adjustments.

For fine tune Calibration, the sensor settings can be adjusted to suit the individual user.

For Voltage Sensor.

The Maximum Value can be adjusted up or

down to suit. (Both must be adjusted by the

same amount).

If Gauge reads LOW, increase these values.

If Gauge reads HIGH, decrease these values

For Current Sensor.

The Zero Value can be adjusted up or down to

suit.

(Maximum Self Adjusts).

If Gauge reads LOW, increase these values.

If Gauge reads HIGH, decrease these values

Troubleshooting

•Litres Displayed Incorrectly.

Usually down to incorrect settings of the Sensor Span. Check Calibration as shown in

Section 7 –Sensor Span. The Span should match the sensor you have.

C22 = 2.55m (Default), C23 = 3.00m, C25 = 5.00m, C27 = 10.0m

•Display does not read Litres.

Gauges when powered will either read, No Sensor Connected, if there is not one, or one of

the calibration screens may be shown. This can be toggles by switching the Cal switch on the

back of the display board.

If no sensor connected, check that one is connected or check the wiring.
