SYSTEM DESCRIPTION OF THE F173-A

Functions and features
The level indicator F173-A is a microprocessor driven instrument designed to display the linearized
level and percentage as well as monitoring the level with four alarm values for a low-low, low, high
and high-high level. 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,
▪
ability to process all types of signals,
▪
transmitting possibilities with analog, alarm and communication (option) outputs.
Sensor input
This manual describes the unit with one analog (0)4-20mA input for the level sensor "-A version".
To power the sensor, several options are available.
Standard outputs
▪
Configurable alarm outputs: two, three or four alarm outputs, depending on the configuration
ordered. The functionality of the output can be user defined.
▪
Configurable passive linear (0)4-20mA / 0-10V analog output with 10-bits resolution representing
the actual level. The minimum and maximum signal output can be tuned.
