GENERAL
The electronic tank management system SmartBox 1, SmartBox 2 and SmartBox 3 can be used
for monitoring of the liquids contained in unpressurized liquids tanks.
In addition to the registration of tank content, other functions can be implemented by system
enhancements, e.g. temperature measurement, data telecommunication, or connection to master
control systems of the building.
The SmartBox 2 has additional relay control functions, e.g. for activating external alarm devices,
solenoid valves, or the dry-run protection function of pumps.
The SmartBox 3 has relay control functions and an audible alarm for minimum level Indication.
When the acoustic alarm sounds, it can be switched off by pressing the ‘Quit’ key.
Thanks to its modular design, the system can be equipped with additional modules, e.g. with an
analog interface or a GSM module for telecommunication.
The indicated measurements are not gaged for invoicing.
The measuring probe is not a safety device, not even in connection with an electronic indicator.
Accordingly, it will not replace a limit monitoring indicator at the tank.
To operate the device as intended and to observe the warranty conditions, it is imperative that
you adhere to this Installation and Operating Manual and hand it over to the user.
DESIGN
The SmartBox 1 has an 8-digit LCD display and a measuring input for connecting the probe. The
SmartBox 2 has additionally 2 programmable relays with make and break switching output. The
SmartBox 3 has a programmable relay with make and break switching output and an acoustic
alarm for minimum level Indication. As a standard, the measuring probe can be installed with tank
connecting thread G1, G1½ or G2.
