Function and Configuration

Indicators
The indicators consist of five LED's – two to indicate RS-485 digital communication, three to indicate the status of relays 1-
3.
RS485-TX/RX:
When the B6 is connected to a controller system via RS-485, the traffic of the communication
can be monitored visually through the two RS-485 indicators. One is RX LED, which indicates
the data stream received in from the controller. The other is TX LED, which indicates the data
stream out of the B6.
Note: If the TX LED or the RX LED is always ON, is indicative of a communication problem.
See Troubleshooting for RS-485.
Relay 1-3 LED:
Indicate the status of each relay. When the relay is actuated/closed, the relay LED is ON. When the relay is de-
actuated/open, the relay LED is OFF.
Note: If you set the relay to be Normally Energized (Fail Safe), the relay LED will turn ON at non-alarm state and turn OFF
at alarm state, because the LED reflects the relay coil status.
