Photo Cell/Sun Switch
The sun switch/photo cell measures the illumination level (lux) and when this reaches a pre-set value it will activate or deactivate the lighting fixture(s).
The input from the (external) photo cell will be led into a light dependent relay, which is installed in the central control panel, which is adjustable between 1 and 100 lx.
The photo cell is housed in a small separate Ex d box or as part of the Control Panel.
