1. KNX MWS3A KNX Product Guide lectronics intelligent energy control Ceiling microwave presence detector KNX Overview The MWS3A KNX microwave presence detector provides automatic control of lighting loads with optional manual control The MWS3A KNX detects movement using a highly sensitive microwave detector This works by emitting low power microwave signals and measuring the reflections as the signals bounce off moving objects The device is designed to be part of a KNX system Features include e Two switch inputs to manually override the dimming levels and or override the lights on or off KNX programming mode accessible with IR handset and also by using the push switch on the back of the unit e Programmable logic block This allows conditions to be set For example send the occupancy telegram only if the switch is pressed and the lux is low Full scene selection functionality selectable via the IR handset UHS7 eg scene on off raise and lower All functionality is fully programmable using the KNX ETS commissioning software Front features Mounting Bezel Ng Sensor Lens which covers Microwave Sensor IR Receiver Light Level Sensor Status LEDs Back features Retaining Spring KNX Communication LED KNX Program Button Switch Input Connector KNX Retaining Spring Connector Microwave Sensor Detects movement within the unit s detection2.

31. xception of the basic movement detection controller The detector contains a light sensor for use as part of the constant brightness controller and to send light level readings to other devices on the KNX bus It is important to note that the light sensor requires calibration in order to produce real lux values and this calibration should take place once installed using a light meter To perform a calibration the light level multiplier should initially be set to 1 0 The room should be furnished as reflected light e g from uncovered floor tiles will dramatically change the measured value Using the ETS group monitor record several lux values for different levels of illumination with the light meter placed normally within the room It will be necessary to assign a group address to the light level output group object Once these values have been recorded the multiplier can be calculated as follows 1 lightmetervalue Light meter value Detector value Calculated Multiplier Multiplier __ For example detectorvalue 590 534 1 105 928 816 1 137 An average of the calculated multiplier values yields a multiplier of 1 121 General settings Setting Options Description Sensor walk test LED Disable Enable or disable the sensor walk test LED triggered Enable when movement is detected This is useful for commissioning or if the detector is to be used in bedrooms Note that the walk test function ca
