Solution
Adjust to the specified voltage range
Check the wires and plug connections and LED status
Check that the metal filings from drilling are removed
Check that the correct ELS 300 types are used
Check the installation distance and condition
Check that there is no mirroring possible
Check that no other opto-electronic devices interfere with
the installed ELS 300 system
Check that no beacon lights, e.g. from fork-lift trucks, are
directly flashing into the ELS 300 from short distances
Remove the obstruction
Clean the front surface with a soft towel from dust or dirt
