GAMMA instabus Technical Product Information May 2008 AP 251/11, Motion detector IP55 (titanium white) AP 251/21, Motion detector IP55 (anthracite) 5WG1 251-3AB11 5WG1 251-3AB21 Product and Applications Description blocked no telegram will be sent neither at the beginning nor at the end of a detected motion. Installation Instructions * The device can be used for permanent installations in inside or outside areas. V The IP55 motion detector (short title AP 251/_1) is a surface mounted device with integrated KNX interface for mounting on a wall or ceiling (see figure 1) in inside or outside areas. It works by passive detection of heat radiated by bodies in its capture zone. It can be set separately for the beginning and end of detected movements, whether these are to be reported over the bus and whether a further telegram is also to be sent. Owing to its large capture zone of 290, the motion sensor is also suitable for mounting on a 90 outside corner. A special mounting base is available for this purpose as an accessory (5TC7 900 in titanium white and 5TC 901 in anthracite). By using an infrared remote control which is also available as an accessory (5TC7 902), a user can conveniently set, by means of the IR receiver incorporated in the motion detector, as well the detector's mode (test mode, brightness-dependent or brightness-independent mode, standard mode, pulsed mode) as the brightness threshold and the delay time, independently. The factory setting of the mode in the as-delivered state is brightness-dependent motion detection with a brightness threshold of 7 lux and a delay time of 2 minutes. The detector electronics are powered via the bus voltage. Application Program The motion detector AP 251/_1 requires the application program 25 S1 Motion Detector 909101" which can be configured and loaded with the Engineering Tool Software (ETS) from version ETS2 V1.3 upwards. Via the ETS it can be set separately for the beginning and end of detected movements, whether these are to be reported over the bus, whether the telegram "Movement = On" respectively "Movement = Off" has to be sent only once or cyclically and whether an additional telegram is to be sent only once or cyclically. The telegram to be sent additionally may be a switching command On/Off, an 8bit value (0-255) or a telegram for recalling an 8-bit scene. Via a separate communication object the motion detector may be blocked and released if required.

Technical Manual Update: http://www.siemens.com/gamma 2.13.1.5/2 Capture zone In order to avoid unwanted responses from the motion detector, you must consider potential sources of interference (such as warm air flows, moving bushes or trees). Unwanted capture zones can be filtered out as required by fitting the cover screen supplied. It is to be cut out accordingly for this purpose. The cover screen fixing ring must not be separated when cutting out segments (see figure 4). No movements will be captured by areas of the lens covered by the cover screen.

The capture range can be changed by adjusting the tilting arm (see figure 5). The bus cable is to be brought in through one of the punched out openings in the connection box. The insulation of the red and black wire is to be stripped back for approx. 5 mm, the wires are to be plugged into the part of the bus terminal with the same colour and the bus terminal is then to be plugged into its mounting on the detector's printed connection board. The detector is then to be plugged into the connection box and screwed to it with the fixing screw (see figure 8). Figure 5: Adjusting range of the tilting arm Mounting and connecting the bus cable The motion detector's connection box must be correctly positioned when mounting on a wall (TOP showing, see figures 6 and 7). You can use the dowels and screws supplied for this. The spacing of the drilled holes in the connection box is to be matched on a 60 mm flushmounted socket. Figure 8: Screwing of the motion detector Depending on the requirement and the type of mounting, the corresponding condensation opening adjoining the screw opening is to be punched out (see figures 7 and 9).

For this, the detector output is switched on approx. 2 seconds. The red LED inside the lens flashes approx. 3 times per second, until the device enters test mode automatically after a maximum of 45 seconds. Test mode Test mode is a brightness-independent mode with an ON period of 1 second and an after-run time of 2 seconds. It can be used for manual checking of the capture zone and to change the alignment or sensing angle of the lens. At the end of the test mode period of 10 minutes, the motion sensor switches automatically to the factory setting (brightness threshold 7 lux, delay time 2 minutes) or to the individual setting made. Test mode will be started automatically on first connecting to the bus voltage only after the initialisation phase has cycled. During any later bus voltage failure, only the initialisation phase will then be recycled and the motion sensor then enters the individual setting directly or the factory setting if no individual setting has been programmed yet. If test mode is re-activated, then this can be triggered by holding down S1 and S2 simultaneously for at least 3 seconds (max. 5 seconds). The LED also flashes quickly for 3 seconds and then stays ON. If you now release the buttons, then test mode is confirmed by the LED flashing twice. Test mode can be interrupted prematurely by tapping S1 or S2 (see figure 2). Mode and parameter settings The following table shows the setting options using the S1 and S2 pushbuttons. Whereas the detector is switched on for the set delay time with every motion captured during brightnessindependent operation, during brightness-dependent operation the detector is switched on with a captured motion only if the brightness falls below the set switching threshold. If a brightness switching threshold differing from the factory setting is wanted, then the user can store the current brightness value as the new switching threshold in the detector's memory by holding S1 down for a period of less than 3 seconds. When doing this, take care that the sensor is not covered by the user while storing the new value. In pulsed mode, the detector output is switched on for 1 second after the brightness falls below the threshold and motion is detected. It will then no longer respond to a movement for 9 seconds.
