1. INTRODUCTION
1.1. SYSTEM DESCRIPTION OF THE F090-A-PL
Functions and features
The general purpose indicator model F090-A-PL is a loop powered microprocessor driven
instrument designed to display the actual value, like level, temperature, flow, pressure etc.
This product has been designed with a focus on:
▪
ultra-low power consumption to allow loop powered applications (type PL);
▪
intrinsic safety for use in hazardous applications (type XI);
▪
several mounting possibilities with GRP or aluminum enclosures for industrial surroundings;
Sensor input
This manual describes the unit with an analog 4-20mA input type from the sensor "-A version".
One sensor with an active 4-20mA signal output can be connected to the F090-A-PL.
The F090-A-PL is powered from the loop (sensor signal) and does not require any additional
external power supply.

Configuration of the unit
The F090-A-PL has been designed to be implemented in many types of applications. For that
reason, a SETUP-level is available to configure your F090-A-PL 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.
Display information
The unit has a large transflective LCD with all kinds of symbols and digits to display measuring units,
status information and key-word messages.
The actual values
is displayed with the large 26mm (1”) digits while the smaller 8mm (0.31”) digits
display the measuring unit and messages.
The Piegraph is percentage-wise related to the span.
Options
The following options are available: intrinsic safety, panel-mount, wall-mount and weather-proof
enclosures, flame proof enclosure and LED backlight.
