SYSTEM DESCRIPTION OF THE F073-T

Functions and features
The level monitor model F073-T is a microprocessor driven instrument designed to display level,
percentage or the height as well as the monitoring of the level for high / low values.
This product has been designed with a focus on:
 ultra-low power consumption to allow long-life battery powered applications (type PB / PC),
 intrinsic safety for use in hazardous applications (type XI),
 several mounting possibilities with aluminum or GRP enclosures for harsh industrial
surroundings,
 alarm transmitting possibilities with one switch output.
Sensor input
This manual describes the unit with a resistive array input type, known as "-T version". This version
is capable of reading resistive array sensors such as a reed chain. Other versions are available to
process a 0(4) – 20 mA or a 0 – 10V sensor signal.
One resistive array (preferably ≤ 20kΩ) can be connected to the F073-T.

Configuration of the unit
The F073-T has been designed to be implemented in many types of applications. For that reason, a
SETUP-level is available to configure your F073-T according to your specific requirements.
It includes several important features, such as Span, measurement units, display options etc. All
setting are stored in EEPROM memory and will not be lost in the event of power failure. To extend
the battery-life time, please use of the power-management functions as described in chapter 3.2.3.
Display information
The unit has a large transflective LCD with all kinds of symbols and digits to display measuring units,
status information, trend-indication and key-word messages.
Level and alarm values are displayed with the large 17mm digits while the smaller 8mm digits can
be set to display either the height or percentage filled.
Options
The following options are available: intrinsic safety, power- and sensor-supply options, panel-mount,
wall-mount and weather-proof enclosures, flame proof enclosure and LED backlight.
