11.2 Field devices
All field devices are fitted with a power supply input of 11
÷
14Vdc, and a BUS communication
connection line.
They are internally fitted with a configuration button and a status LED that can show three
display statuses
•
Rapid flashing (1 Hz): field device to configure
•
Slow flashing: configured field device (lamp flash every 10 sec.)
•
Steady on: sensor in alarm condition (PR, 1t, 2t exceeded or FA)
The LED can be forced to "steady on" by setting up the control unit (forced or FA of the
sensor status); this allows the operator to visually identify the configured field device.
