The compact design allows it to be installed in space limited locations, where traditional motion sensors cannot be installed. The microwave technology allows the sensor to be mounted behind plastic constructions for out-of-sight installations. The Doppler radar sensor detects objects that are in motion towards or away from the sensor. People passing the sensor perpendicular (i.e. with no intention of entering an escalator) will have no or very low speed relative to the sensor such motion can remain undetected. The detection field is divided into two parts; low-speed zone and highspeed zone. The part of the field closest to the sensor is the low-speed zone where low speed motion is detected. This is intended to detect people in a multi-storey building that are moving from one escalator to the next making a semi-circular movement/turn i.e. perpendicular to the sensor and with a relatively low speed. The extension of the low speed zone relative to the high speed zone can be adjusted from 0 100% of the total range. Total range is also adjustable. The sensor also includes a background suppression feature which allows the sensor to ignore all constant movements of minor objects (either directly or indirectly detected through reflections) e.g. handrails.

Pin 2 / Adjustments Mechanical adjustment Sensor plug Notice that the sensing field is not symmetrical. The sensing field is in the direction perpendicular to front of the housing. The sensing field is narrow in the directions where the cable is inserted and wide in the direction orthogonal to the cable insertion. Notice that there are two different types of the sensor marked with L and H. Whenever two sensors are used to detect the same objects, use one of each type, to avoid risk of interference.

The enclosure can be taken apart if the 4 top screws are removed, and the PCB-board will be visible as shown in figure 1. Potentiometers (*) Extension of high-speed zone adjustment Within the sensing range, there are two zones; a high speed zone and a low speed zone. In the low speed zone which is close to the sensor, objects with speeds down to app. 20 cm/s will be detected. This is advantageous in order to detect crossing traffic close to the escalator, for instance when traffic is passing from one escalator to the next escalator in a multi-storey building. In the high speed zone only objects with speed larger than 0.4 m/s = 1.5 km/h will be detected. This will to reduce cross-traffic detection, but on the other hand still detect motion towards the sensor. (*) See figure 1. For radar sensor it is the speed towards the sensor that matters. (or more precisely the magnitude of the velocity projected on the line between the sensor and the object). Increasing the potentiometer will increase the fraction of the high speed zone and reduce the size of the low speed zone. Delay on de-activation of output can be adjusted between 0 s and 10 s Dip switches (*) 1 Background suppression on/off. Minor signals from constant signal contributors as for instance fluorescent light tubes and constantly moving parts as handrails on escalators, that may lead to unwanted detection are suppressed. Disable the function if it is not needed. Wiring diagrams The sensor has a solid-state relay output, and for the dc-versions also with an integrated output monitor Sniffer. Connect as below to ensure correct function of the sniffer. If faulty connected or failure is found the output is de-energised and the yellow LED will start blinking. Ensure correct connection and repower the sensor to escape the fault mode. If there is no Sniffer, i.e. the ac/dc-versions, there are no special requirements for connection of the opto-coupled solid state relay output. Configuration of NPN output 2 Signal summation on/off. If signal summation is on, multiple objects with different speed are all contributing to detection. Can provide more consistent detection of for instance legs, because these consist of different minor parts moving with different velocity relative to the sensor. Turn signal summation off if the range is larger and the sensor is directed towards the body, because the sensor then will have less sensitivity to background traffic. 3 (**) Direction sensitive on/off. If on the sensor will only detect objects moving towards the sensor. If off the sensor will detect both objects moving towards and away from the sensor. (*) See figure 1 (**) Only present for direction sensitive types Logic Detection indicator Moving objects present OFF OFF No objects or non-moving objects ON ON Configuration of PNP output Electrical adjustment Turn potentiometer fully clockwise for maximum range. Turn Off-delay fully anti clock wise to remove off-delay, for instant response. Turn high speed zone fully anti clock wise to remove high speed zone, for maximum motion sensitivity. This setting corresponds to the factory setting. Check if the sensing distance is adequate, but not excessive. Turn the potentiometer anti clockwise in steps until suitable range is obtained. With the speed zone set to zero (fully anti clock wise) the sensor will detect all motions down to 20 cm/s in the full sensing range. Crossing traffic will therefore be detected in the entire sensing range. Turn the speed zone potentiometer clockwise in steps in order to make the part of the sensing zone which is distant from the sensor to a high speed zone. Check whether crossing traffic is detected. 4 Finally increase the Off-delay if needed by the control system.
