"Middle of night" is automatically detected as the midpoint between dusk and dawn; no setting of a clock is required. It may take several days until the
controller has "learned" the middle of the night precisely. "Middle of night" may be different from 12:00 midnight depending on your location/longitude.
The controller recognizes day and night based on the solar array open circuit voltage.
The day/night threshold can be modified according to your local light conditions and the type of solar array used.
Dimming Function
Load hours (load 1 on CIS-CU case printing) and dimming hours (load 2 on CIS-CU case printing) work together to affect the dimming function:
Load hours
Dimming hours
The timer and dimming settings can be adjusted using the CIS-CU-LCD (Infrared remote control) or MXI-IR (Infrared to USB adapter) and CISCOM (PC program).
PIR / DIM override input: (0 - 0.5 V Off, 4 - 30 V On)
Input for a signal from a motion sensor (PIR), to override the dimming and set the light to full brightness in case a person is detected.
In this way, one can set a low dimming level to ensure a minimum light level, for sufficient orientation and to save energy.
When a motion is detected, the light is switched to 100%. The duration of the activation has to be adjusted on the motion sensor.
