3.5 LED signals and Reset button
The Rosemount 2230 has three LED signals that show communication and status.
Figure 3-9. LED Signals
Status LED
The status LED indicates error codes using different blinking sequences. In normal operation the LED
flashes every other second. When an error occurs, the LED flashes a sequence that corresponds to a code
number followed by a five second pause. This sequence is continuously repeated (for more information
see
“Device error signals” on page 86 ).
Communication LED:s
Tankbus communication is indicated by a pair of LED:s, see Figure 3-9 . When you connect the Tankbus
cables you can check the communication status with the LED:s.
Reset button
You may use the Reset button to force a restart of the Rosemount 2230 display. Restarting the
Rosemount 2230 has the same effect as switching off and on the power supply.
The Restart option will connect the Rosemount 2230 display to the Rosemount 2410 Tank Hub and
perform start-up tests of software and hardware.
