LEDs
LED settings can be changed using the Device Configuration function; see the LEDs Tab section on page 9 .
Status LED
(Red) • Turned ON at the configured brightness for 2 seconds after application of power (battery
voltage or USB power).
• Turned ON at the configured brightness if a fault is detected.
• Pulsed at full brightness for a 10ms flash once per second if any severe event is present in the
logged events.
Note:
If power is lost during an event, the ADR uses a supercapacitor to maintain power for event
logging and severe event indication.
Power LED
(Green) • Turned ON when external power (battery voltage or USB power) is present.
Data LED
(Blue) • Turned ON at the configured brightness if any events are logged.
• Flashes at 1Hz if the event log is full.
• Flashes at 6Hz if an event is in progress.
External LED The External LED pin is a 30mA constant current output. The LED output has a clamp circuit to
protect the ADR if the output is open circuit. The output can drive a single LED or series chain of
LEDs with a maximum forward voltage of 10V.
• Turned ON as a lamp test at the configured duty for 2 seconds after application of power
(battery voltage or USB).
• Pulsed at full brightness for a 10ms flash once a second if any severe event is present in the
log.
• If the External LED is enabled in the configuration, then an open circuit test will be performed
during the lamp test. The external LED is considered open circuit if the LED driver output
voltage exceeds 11V.
If an open circuit fault is detected during the lamp test, then the External LED output is
disabled until the next power on lamp test.
If a severe event is present and the External LED is configured, the ADR will still attempt to
flash the External LED, even if an open circuit fault has been detected.
