KCI
KNX Consumption Interface
ZRX-KCI4SO 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.
•Size 90 x 60 x 35 mm (2 DIN units).
•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.

SAFETY INSTRUCTIONS
•Installation should only be performed by qualified professionals according to the laws and regulations applicable in each country.
•Do not connect the mains voltage nor any other external voltage to any point of the KNX bus; it would represent a risk for the entire
KNX system. The facility must have enough insulation between the mains (or auxiliary) voltage and the KNX bus or the wires of other
accessories, in case of being installed.
•Once the device is installed (in the panel or box), it must not be accessible from outside.
•Keep the device away from water and do not cover it with clothes, paper or any other material while in use.
•The WEEE logo means that this device contains electronic parts and it must be properly disposed of by following the instructions at

BATTERIES REPLACEMENT
1.
Extract the battery holder from the upper side of KCI. It is recommended to have the bus KNX connected during this
process to prevent S0 pulses loss.
2. Place the batteries in the battery holder (respecting the polarity shown) and insert it as indicated in the figure.
