Radio LEDs:
• The radio TX LED (Green) flashes each time a radio packet is sent. This LED
will blink rapidly while searching for the radio network.
• The Radio RX LED (red) blinks on each received radio packet.
Status LEDs:
• The Active LED (green) will blink at boot up and will blink rapidly when the
sensor is being powered.
• The HART_STATUS LED will blink once to indicate a HART sensor is
connected after a HART scan is completed. A HART scan is conducted at each
power-up or when the Scan/Checkin button is pressed.
• The ERROR LED (Red) will blink to indicate an error condition, such as the
Slave ID being set to 0 which is invalid.
Scan/Checkin Button:
• If this button is pressed the Sentinel will apply power to the sensor for the
configured sensor on time and scan for the HART sensor. If the HART
sensor is detected the HART_STATUS LED will blink once and its data
will be read. The Sentinel will also send the collected sensor data to the
gateway.
