Picture 2: Photometer connection
2. 4. Onboard Indicators
Beside connectors there are LED indicators on the PCB board (see Picture 1). They indicate
current light conditions (green) and contactor output status (red).
2. 4. 1. Use of 230 V AC Contactor Outputs
Those outputs can be connected directly to the coil-side of the light-chain switching
contactors (check contactor’s coil voltage to be 230 V!). Use provided software to distribute
switching combinations according to the light conditions. Example is shown at Table 2 and at
Picture 4.
