TECHNICAL DOCUMENTATION
FEATURES
•
4 channels for consumption counters (meters) with S0-pulse outputs
(UNE-EN 62053-31) *.
•
Registration of consumed electric power, cost and CO2 emissions that
can be split in up to 4 time intervals.
•
Compliant with UNE-EN 62053-31 Class B.
•
Total data saving on KNX bus power failure.
•
KNX BCU integrated.

•
DIN rail unit assembly (EN 50022), with snap fit clamp.
•
CE directives compliant (CE mark on the front side).
*Other counters (meters) with dry-voltage output or not complying S0 standard
may also work (previous test is recommended)

Figure 1: KCI
Programming button: short press to set programming mode. If this button is held while plugging the device into the KNX bus, it enters the safe mode.
Programming LED: programming mode indicator (red). When the device enters the safe mode, it blinks (red) every half second. During the start-up
(reset or after KNX bus failure) and if the device is not in safe mode, it emits a red flash.
LOW batt. LED: if this LED is blinking in red, replace the batteries as soon as possible.
EMPTY batt. LED: if this LED is blinking in red, the batteries are empty.
