General
The electronic tank management system SmartBox 1, SmartBox 2, and SmartBox 3
can be used for monitoring of the liquids contained in un-pressurized liquids
tanks. In addition to the registration of tank contents, other functions can be
implemented by system extensions, e.g. temperature measurement, data
telecommunication, or connection to master-control systems of the building.
SmartBox 2 has additional relay control functions, e.g. for activating external
alarm devices, solenoid valves, or the dry-run protection function of pumps.
SmartBox 3 has relay control functions and an acoustic transmitter for minimum
level messaging. The alarm tone can be deactivated (acknowledged ) with
a button.
Thanks to its modular design, the system can be equipped with additional
modules, e.g. with analogue interface or a GSM module for
telecommunication.
The indicated measurements are not applicable 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 LC-display and a measuring input for connecting
the probe. The SmartBox 2 has additionally 2 programmable relays with make
and break switching output. As a standard, the measuring probe can be
installed with tank connecting thread G1, G1½, or G2.
