GENERAL PRODUCT INFORMATION
The electronic tank management system SmartBox® 4 and SmartBox® 4 PRO can be used
for remote monitoring of the liquids contained in unpressurized liquids tanks.
In addition to the registration of tank content and remote data transfer, other functions can be
implemented by system enhancements, e. g. temperature measurement, message about
system fault or connection to master control systems of the building. A Nano-SIM card is
required for remote data transmission.
Typically, a message will be received by the accounting management system www.smart-
inspector.com. Optionally, the messages can be received on any mobile phone.
The SmartBox® 4 has relay control functions, e. g. for activating external alarm devices,
solenoid valves, or the dry-run protection function of pumps.
Via an integrated interface, a maximum of three more content indicators SmartBox® 1, 2 or 3
can be connected whose measurements are also telecommunicated.
SmartBox® 4 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 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 GSM modem for remote data transmission.
SmartBox® 4 PRO has a 2-line LCD display, four measuring inputs to connect the probes, a
fault message input and an integrated GSM modem for remote data transmission.

ASSEMBLY
Before assembly, check that the product is complete and has not suffered
any damage during transport.
ASSEMBLY must be carried out by a specialised company.
The specialised company and the operator must observe, comply with and understand all of
the following instructions in this assembly and operating manual. For the system to function
as intended, it must be installed professionally in compliance with the technical rules
applicable to the planning, construction and operation of the entire system.
These regulations also include the accident prevention regulations of the employers’ liability
insurance associations, the VDE regulations, and the installation and operating instructions.
The housing of the display unit is suitable for wall mounting and is connected to
the 230 V mains supply. Under normal circumstances, the display unit must be operated with
the housing cover closed.
It is installed and started up by a qualified technician while the unit is open.
Do not use this device for safety applications or emergency stop mechanisms
or misuse it!
Injuries and damage to health and property through misuse.
You must observe the information contained in these instructions, especially
regarding installation, start-up and maintenance.

SmartBox® 4 / SmartBox® 4 PRO

Damaged or destroyed insulation!
Can result in short circuit or electric shock.
Do not use the device if the insulation is damaged!
Have new insulation installed by a specialised company!
Selecting an installation location / Checking the reception quality of the mobile phone
network
Before installing the SmartBox®, you must check whether the reception quality of the
applicable telecommunications network is sufficient. The easiest way to do this is to have a
mobile phone ready at the designated place of installation. As a precondition, the mobile
phone must be registered with the same telecommunications network (in Germany e. g. T-
Mobile, Vodafone, O2) as the SIM card which is used for the SmartBox®.
If there is no suitable mobile phone at hand, you can also perform the test with the SIM card
for the SmartBox®. In this case, insert this activated SIM card into a mobile phone and switch
it on again.
The reception quality at the designated place of installation can simply be seen from the
indication in the mobile phone screen. At least one bar/scale line of the reception quality
indicator must be visible on the screen. If the reception quality is very bad (no bar/scale line
visible), another installation site should be picked and tested (possibly in another room).
If the reception quality is very bad, an additional antenna (accessory) should be used. It can
be installed e. g. in front of a basement window.
Installation of the display unit
Mount the display unit to the wall in a suitable position.
1. Open the display unit by removing the bottom cover.
2. After loosening the 2 screws, open the display unit by removing the cover.
3. Mount the display unit to a smooth vertical wall by means of dowels by the four fixing
holes with the enclosed screws and anchors. Take care not to damage the housing.
4. After connecting the terminals and setting the unit up, replace the covers.

additional tanks (tank 2 to tank 4) can be telecommunicated.
For SmartBox®1 and 2, the two-pole output terminal “Serial Link Output“ (terminals 3 + 4) is
con-nected to terminals 3 + 4 (terminal 3 3 and 4 4) of the SmartBox®4 with a two-core
cable (e. g. 2 x 0.4 mm²).
If the tanks should be numbered in a defined sequence (tank 2 to 4), then SmartBox®4 must
be activated first, followed by the other indicators in the desired sequence.

SmartBox® 4:
Activation of other indicators (and assignation of the respective tank numbers)
Numbering the tanks:
The contents indicator SmartBox®4 always has tank number 1.
If other content indicators SmartBox®1, 2 or 3 (indicator) are to be connected “SERIAL LINK
INPUT“ (terminals 3 + 4), they must be assigned defined tank numbers. The tank numbers
are simply assigned in the sequence in which the indicators log on for the first time.
•First, activate indicator 2 for tank number 2 (switch on mains voltage), then for indicator 3,
and so on.
Example: Activate tank 2
•After connection the indicator of tank 2 as described under Electrical Installation –
Connecting the Interface to SmartBox®1, SmartBox® 2 or SmartBox®3, switch on the
indicator of the tank in question (switch on the mains voltage).
In the display of SmartBox®4, the following will be indicated alternatingly: “Tank1:” - “xx.xxxL“
– “Tank2:“ – “yy.yyyL“ (depending on the selection / adjustment in the menu 14.Show tanks).
Then, follow the same steps for the other indicators.
You have now completed the on-site installation.
The order of the displayed tanks can be changed subsequently under menu step
16.Sort. Tanks

PROGRAMMING THE REMOTE MONITORING FUNCTIONS
If the device is linked to www.smart-inspector.com, this is done via the Internet.
As an alternative, the setting parameters for remote monitoring functions of the SmartBox®
can also be transmitted via SMS by any mobile phone. This can be done directly on site or
optionally at a later time, e.g. from the company headquarters.
Command to the device (from a mobile phone)
•An SMS may contain one or several commands.
•However, the total length of the SMS must not exceed 80 characters.
•There must be no spaces between the SMS commands and no special characters!
•When entering a chain of commands, the commands #R or #M or #C must come at the end,
if applicable.
Setting the SMS target number (number of the receiving building supervisor):
•Enter the SMS text ... #T=01701234567#M (i.e. the number of the reporting mobile phone)
•... and send it the mobile network number of the SmartBox®.
•Because of #M, the SmartBox®will send an SMS in reply (possibly after 1 - 2 minutes’ wait).
•The SmartBox®indicates reception of this SMS by showing “Receive” in the display.
•The transmission of the reporting SMS is indicated by showing “Sending” in the display.
Setting of unit names for the text messages of the system
•Enter the SMS text #H=Tankmonitoring Jones NameofPlace #R
•... and send it the mobile network number of the SmartBox®.
•Commands as #T=... #H=... and #R can be sent as a chain in one single SMS.
Example: Complete setup by means of one single SMS containing a chain of commands
#T=01714901312#H=Ct-024Tankmonit.K.Miller,LevenhamRd.21#P=10,07,15,01#R
See page 22 for a list of all commands.
