Principle of Operation
Digital Tank Gauge. Accuracy +/- 0.25%.
This gauge is fitted in a weatherproof rated IP65 enclosure, for outdoor use. Fitted with a backlight that
enables easy reading (Backlight turns off after 1 hour). Litres and % Bar are displayed.
M (Master) and up to 3 other trigger points can be displayed.
The gauge can be setup for almost any tank shape, such as Cuboid, Rectangular, Cylindrical, Cylindrical with
dished ends, bespoke based on strapping table. (Level in meters and volume in cubic meters).
Can read temperature as an option, temperature probe required. “TP” probes read 0°C to 70°C.

Gauge Configuration
The set-Up of the Tank Gauge system using Interface lead and he software on a PC / Laptop.
Latest version of the software is V1.0.0.16
Tank Gauge adjustments can be made with the T4020 Configuration software.
This needs to be loaded on to Service Laptop or an Office PC.
1st Issue that will nearly always catch you out. If the gauges are set in ‘Modbus’ mode, or if they are in
Standard. To talk to the gauge with the configurator software, the gauge needs to be in Standard mode.
If it is not, disconnect the power lead (24vdc supply), and hold down the front middle alarm button (for 3
seconds) and reconnect power. (Front display will change to ‘Standard’. (Cycle power again when finished.)
2nd Issue, the comms lead will not talk to the tank gauge. “USB Serial Com Port”
This is the port you require to set the configurator, this is achieved by following the instructions for the Device
Manager below. This shows Windows 10, but if you have a different version of windows as long, as you can
access the device manager and find the com port number there shouldn’t be an issue.
IF YOU HAVE ANY ISSUES WITH SETTING UP / ACCESSING THE DEVICE MANAGER
PLEASE REFER TO DOCUMENT PD02/0003 –DEVICE MANAGER CONFIGURATION.
This is available from the OLE website as a downloadable .pdf
Windows Setup (Windows 10) / Device Manager.
Left click on the This PC icon. Scroll down and click on the Properties tab.
This will open the Control Panel / System and Security / System page. Click on the Device Manager Icon.
This will bring up the device manager page.

Page 7of 22
Scroll down and there will be a folder Ports (COM & LPT). It should show the USB Serial Port with the Com
port it is attached to, in this case, (COM7), this will vary on whatever computer the programmer is attached.
This is the figure that is entered in the T4020 Configuration Software. The communications lead RED LED
should flash when you try to connect the USB programmer to show the address for the lead is correct.
Connect the Programmer to the T5020 Gauge as shown in Page 4.
Configurator Software.
Next step is to open the T4020 Configuration Software.
Click on the File tab. On the drop down menu, click on the Program Settings tab.

Page 8of 22
This will open the Settings screen (Shown Below). Select from the drop down menu the Com Port number (as
shown in the device manager) and click OK.
Next step, click the Device tab at the top of the screen and click Connect.
A pop up screen, Input Value will show, click on OK.
99 is a global address which will work if only have one gauge connected.
Click on Yes on the Information screen.
Now the software will connect and “talk” to the unit, as shown in the bottom left of the configuration screen.
When the unit has connected, it will show CONNECTED in the bottom right of the Configuration screen.

Page 9of 22
Click on the Display Options tab.
Current Contrast Value, default is 47%. Set as required.
Number of Significant figures is 5. On the T5020, there is the option to choose Resolution of Display, e.g. 50
Litres or 10 Litres etc. Set as required. 10.00 for instance.
Display Units of Measure, set to Litres unless otherwise requested.
Screen Damping, makes the screen more stable, suggest 2Seconds.
When this screen is complete, Click Write Settings.
Click on the Sensor Parameters tab. Note: Set to Suit the Sensor, NOT THE TANK.
Sensor Min, set to 0.050m (50mm) as standard.
Sensor (Min) Reading set to 4.00mA
This would mean for example a 2.0m Sensor, would be set as a Sensor Min 0.050m to a Sensor Max 2.050m.
and a 3m Sensor would be Sensor Min 0.05m and Sensor Max 3.050m etc.
Sensor Max, set to Sensor 0.050m plus the Sensor length as shown in example above.
Sensor (Max) Reading set to 20.00mA
Enter the Specific Gravity of contents.
When this screen is complete, Click Write Settings.
Specific Gravity of liquids.
Gasoil = 0.84
Diesel (DERV) = 0.835
Kerosene = 0.80
Petrol = 0.745
AdBlue = 1.09
Rapeseed Oil = 0.92
Lube Oil = 0.89
Antifreeze = 1.11

Click on the Tank Settings tab.
The next step is to set the tank shape up. Enter the tank type from the scroll down menu, a name for the tank
and the measurements.
Ensure that the Enable 4-20mA Output is ticked.
Please make sure the Mirror Output box is NOT ‘Checked’ (ticked). If it is we need to discuss.
The Mirror input may be used when a second Gauge is set exactly the same as the first. Alternatively, the
second Gauge can be set to have the Sensor Parameters the height of the primary tank and this will work over
the full 4-20 milliamp range of the first gauge output. No sensor offset required.
When this screen is complete, Click Write Settings.
Click on the Alarm Setpoints tab.
Set the Alarm settings as required (High is normally 95% Rising).
Set the “Direction” to “Rising” or “Falling”. This will result in energising the Relays (R5 Option Board) if fitted
in that ‘form’.
Rising at 95% on the M alarm will output 24vdc when the level increases to 95%.
When this screen is complete, Click Write Settings.
Note: that the tank can be taller than the
sensor range due to specific gravity.
For example, the tank being 2.2m tall. If we say
this is Diesel (DERV), then 2.2 x 0.835 = 1.837
affective range on the sensor. This means we
can use a 2.0m sensor in a 2.2m tank.
A 3.0m sensor will work fine as well

Next step is to Access the T5020 additional settings and Summary Screen, press the Ctrl, and letter H keys
simultaneously, and click on Device Status Tab.
This will bring up the summary screen of what has been programmed into the unit as shown above
The Summary page. Click on the Device tab at the top of the screen and click Read All settings. This will
display all the settings that has been programmed. Next stage is to enter the final information on this screen.
Unit Serial Number: This is the serial number on the label of the front of the unit.
Safe Working Capacity: If the unit is a T5020, the Safe Working Capacity can be set to say 97%. In this case
the Alarms are based on the Safe Working Capacity value, so 10,000 litre tank has SWC of 9,700 litres. An
Alarm set at 95% will be 95% of 9,700 litres, not of 10,000.
Mount Sensor: 50 mm off the bottom of the tank.
Bund Alarm: If fitted, click YES, if not, Click NO.
Comms Type: Generally, set to Standard.
Name, Who, setup the unit, Date when setup and a File Saved as Name. XXXXXXXX.tls
Click the File tab at the top of the screen and then “Save As”. When this screen is complete, click the Device
tab at the top of the screen again and then Write All Settings.
ONLY READ AND WRITE SETTING FROM THE DEVICE TAB AT THE TOP OF THE PAGE.
If you have selected ‘Non-Standard’ as the tank type and put in a strapping table, you may have to “Write All
Settings” Twice. Click on Disconnect. Remove the programming lead. This completes the calibration.
Result, you should have a fully calibrated working Gauge, with 4-20 mA proportional to Litres, and either a
Standard or Modbus RS485 output.

B2-T –Water and Temperature Sensor

Page 19 of 22
TP –Temperature Sensor
The temperature sensor is a thermistor housed in a 316 Stainless Steel body. The standard cable is
Polyurethane sheathed and 10.0m in length and supplied with a 1” fitting.
It measures the temperature of the fluid in the tank from 0°C to 70°C.
Not suitable for ATEX applications. This probe requires a second tank connection point.

TP –Temperature Sensor
R5 –Relay Module
The R5 –Relay module is a “Plug In” board that connects to the “Output Connections” header on the
main T5020 board. This allows 5Volt Free switchable outputs. This board is supplied separate to the
gauges and is connected by the installer.
There are 2 sets of SPDT terminals for the 4 level settings and 1 x SPST terminals for the Bund / High
/ Water probe.
The switches are wires Com (C), Normally Open (N/O) and Normally Closed (N/C)
The contacts are rated ate 2A at 240VAC
Level settings can be factory set or by the installer using the Configuration Software.
