3. Function and Configuration
3.1 Indicators
The indicators consist of five LED’s – two to indicate RS-485 digital communication, three to
indicate the status of relays 1-3.
3.1.1 RS485-TX/RX
When the Q6M 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 Q6M.
Note: If the TX LED or the RX LED is always ON, is indicative of a communication
problem. See Troubleshooting for RS-485.
3.1.2 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.
