Night Detection Function
Night detect (V) (rotary switch 12) is used to set the night detection
voltage. For the controller, dusk starts when the panel voltage falls
to this value. Dawn starts when voltage rises to the day detection
voltage, which equals night detection + 1.5 V. To find the
appropriate value, we recommend measuring the solar array open
circuit voltage at the time when twilight has reached the level when
the controller should assume night has begun.
CIS factory default is 8 V.
NOTE: Toggle Switch 4 is reserved for future use.
CIS-CU Working Range
The CIS-CU can operate at up to 10 m distance from the CIS
provided you are positioned and the CIS-CU is pointed directly in
front of the CIS unit.
If you would like to configure more than one CIS, be sure to have
visual proximity/contact to only one CIS unit at a time. To assure this,
keep a minimum angle and distance to the others as shown below.
