4.6 Heater operation
All models have an integrated 20W heater element. The heater starts working when the light internal
temperature drops below 10°C. Heater reaches 100% operation when temperature drops below 5°C. Heater
stops working after the temperature rises above 10°C.
4.7 Causes for ALARM
The following events can cause an ALARM:
Internal hardware or power failure.
Light source failure, including decreased intensity level below rated level of light.
Loss of GPS synchronization signal or GPS module failure.
Incorrect photocell operation.
The ALARM LED will turn on and ALARM relay will activate.
4.8 On-board LEDs
Status indication LEDs are located on the controller board. Some of the status indicators have three
operating states (off, on and flashing). The lights have three status LEDs on the controller board. These
status LEDs are visible only when service access hatch is open, except the ALARM LED that can be seen
through the glass cover.
LED
Description
POWER
Internal operating voltage (GREEN)
LED OFF: Unit has power off
LED ON: Unit has power on
COM
Communication (GREEN)
LED OFF: Waiting for external signals
LED FLASHING: Master-slave communications occurring on the network
ALARM
Alarm indicator (RED)
LED OFF: Normal operation, no alarms
LED ON: Active alarm condition
4.9 GPS operation
In stand-alone mode, light heads will automatically synchronize their flashing with their built-in GPS module.
After light head start-up, it will take some time for the light head to acquire a GPS lock, because the lights
need a signal from multiple GPS satellites. The GPS provides same timing information for all the lights, so
they will flash in sync.
4.10 Troubleshooting
The light doesn´t start
•
No power (check that the POWER status LED is illuminated).
•
Incorrect configuration (check DIP switches, make sure Test mode is turned off).
•
Loose wires (check that all wires are properly seated in terminal block connectors).
•
Do not exceed maximum operating voltage. Mains power supply input is protected with overvoltage
protection circuit that is tuned to stated operating voltage range.
No Modbus data connection to Obelux controller
•
Check DIP settings. Check that light has a correct Modbus address and that there are no conflicting
addresses. Make sure the light is configured to Modbus mode (DIP8).
