GENERAL PRODUCT INFORMATION
The electronic tank management system SmartBox®4 LAN, SmartBox®4 LAN PRO can be
used for remote monitoring of the level in unpressurised tanks containing liquids.
In addition to recording the tank content and remote data transfer, other functions can be
implemented by system enhancements, e. g. temperature measurement, reporting system
faults or connection to master control systems of the building.
The SmartBox®4 LAN has relay control functions, e. g. for activating external alarm devices,
solenoid valves, or the dry-run protection of pumps.
Via an integrated interface, a maximum of three more level gauges indicators
SmartBox®1, 2 or 3 can be connected and their measurements monitored remotely.
SmartBox®4 LAN PRO allows the content of up to four tanks to be recorded and monitored
remotely.
Because of its modular design, the system can be modified to suit many different applications.
The indicated measurements are not calibrated for invoicing.
SmartBox®4 LAN has a 2-line LCD display, a measuring input for connecting the probe, a
programmable relay with make and break switching output, a fault message input and an
integrated network connection for remote data transmission.
SmartBox®4 LAN PRO has a 2-line LCD display, four measuring inputs to connect the
probes, a fault message input and an integrated network connection for remote data
transmission.

Tanks with inner shell
For tanks with an inner shell (e.g. cylindrical horizontal or tanks welded together in the
basement) the data in steps "4.Tank volume" and "5.Internal tank height" must be corrected.
Examples:
Wall thickness of inner casing 0.5cm reduce value for inner height by approx. 1cm,
reduce volume for 10m³ by 1.3%, for 20m³ by 1 %, for 50m³ by 0.8% and for 100m³
by 0.7 %.
Wall thickness of inner casing 2cm reduce value for inner height by approx. 4cm,
reduce volume for 10m³ by 5%, for 20m³ by 4%, for 50m³ by 3% and for 100m³ by 2.5%.

-Activation of other indicators (and assignation of the respective tank numbers)
Numbering the tanks (if applicable)
The level gauge SmartBox®4 LAN always has tank number 1.
If other level gauge SmartBox®1, 2 or 3 (display unit) are to be connected, they must be
assigned defined tank numbers. The tank numbers are simply assigned in the sequence in
which the display units log on for the first time.
•First, activate display unit 2 for tank number 2 (switch on mains voltage), then for display
unit 3, and so on.
Example: Activate tank 2
•After connection the display unit of tank 2 as described under electrical installation –
Connecting the Interface to SmartBox®1, SmartBox®2 or SmartBox®3, switch on the
display unit of the tank in question (switch on the mains voltage).
In the display unit of SmartBox®4 LAN, the following will be indicated alternatingly: “Tank1:” -
“xx.xxxL“ – “Tank2:“ – “yy.yyyL“ (depending on the selection / adjustment in the menu step
6. Show tanks). Then, follow the same steps for the other display units.
The order of the displayed tanks can be changed subsequently under menu step

CONFIGURING THE NETWORK COMMUNICATION
Network communication for the device is configured via the menu item "15.Network".
By default, DHCP is enabled with "Yes". In this case, the device is assigned its IP address,
subnet mask, gateway and DNS server address automatically by the router.
Alternatively you can/should configure these address parameters manually. To do this, select
"No" in DHCP. In particular, your network administrator should confirm the port no. for the
device.
When the network cable has been connected, the device can be addressed in the network
(LAN) with a browser. To do this, enter the IP address of the device, such as 192.168.0.112,
in the browser's address line.
It is generally advisable to involve the network administrator for these configuration settings.

Overfilling of the tank due to incorrect entry values.
Operating media may leak. These:
•are hazardous to water,
•are category 1,2 and 3 inflammable liquids,
•can ignite and cause burning,
•may cause falling injuries due to slipping.
Enter these values with care!
The entry values are also retained in the event of the failure of the supply voltage.
Device connection in the network
The Ethernet network connection is established as follows:
Option A: Direct connection for testing
Connect a PC/laptop directly with SmartBox®4 LAN with a crossover cable
Option B: Mini network
Connect a PC/laptop with SmartBox®4 LAN via a switch or router
Option C: LAN/intranet
PC and SmartBox®4 LAN are connected directly to a local network (LAN/intranet). In each
case the SmartBox®4 LAN and the PC must be in the same network segment or be able to
"see" each other via corresponding routers
