and rectified.

full lamps test must be performed to verify that all lamps are operating correctly.

•
Status and Configuration → Controller → Phases → Lamp Test
To use this facility level 3 access is required and the signals on/off switch MUST be in the OFF
position.

6.9.13 Solar Cell Testing
Solar Cell Testing
For this test to be performed the ambient light conditions must be appropriate to set the bright
condition on the controller.
Correct operation of the solar cell can be checked by covering the solar cell for at least one minute
and checking that the controller (suitably configured to allow dimming) dims the signals. Remove
the cover and check that the signals return to the bright condition.
