Too many RS-485 termination resistors (120ohm) on the same RS-485 communication bus. Only the
last light on the bus should have the termination resistor in use.
•
Check Modbus data wiring.
Light does not change modes between day, twilight and night
•
Check that the photocell has an uninterrupted view of the sky.
•
Check that there are no external light sources that interfere with the photocell.

Photocell is sampled once in a minute and read values are averaged to avoid sudden state changes.
Unless test mode is enabled, it takes approx. three (3) minutes to change system state between day,
twilight and night.
Light does not flash in sync
