PD4/M LUXOMAT PD4/S - Light Sensor

1 2425 Thank you for purchasing the occupancy have opted for a quality product from the BEG range and for one which has been manufac-tured, tested, packaged and despatched with the utmost read the information contained in these directions before commencing of the article numbers:ModelSMFCFMPD4/M Master921409214892255PD4/S Slave921429225492163We reserve the right to make any technical adjustments which are in the interests of product-improvement. Important: All work on the 230V power system must be carried out by qualified personnel only!

2 The mains voltage must be cleared prior to com-mencement of assembly of the LUXOMAT .With its infrared remote-control system, BEG is one of the first manufacturers worldwide to facili-tate control and programming of a occupancy detector using telecontrol does away with the need for erecting a ladder, and the setting of the presence-detector parameters can be carried out with considerably Operating and mounting instruction occupancy detector PD4/Master and Slaveless effort, in particular in situations where there is a large number of occupancy detectors in use, such as, for example.

3 In the case of large-scale office the motion detectors designed for external use which have dominated the sector up to now, occupancy detectors are considerably more sensi-tive and, as such, are particularly suited for internal applications; in addition to moving activity, they will also pick up activity of a sedentary PD4 ceiling-mounted occupancy detec-tors are available in designs intended for both surface- (PD4-SM) and flush-mounted (PD4-FM) installation as well as for built-in ceiling installation (PD4-FC). No further steps require to be taken in the case of the models which have been designed for surface-mounted installation; they can quite sim-ply be installed on any level surface.

4 The models which are intended for flush-mounted installation are compatible with conventional inlet of the appliances are available both as a Master and a Slave version:MasterThe occupancy detectors LUXOMAT PD4 Master feature 2 relay contacts, which may be set independently of each other. Contact 1 triggers the lighting, reacting to movement and ambient degrees of brightness. Contact 2 is voltage-free and will trigger any number of appliances as a reaction to movement. The Master-appliance has extensive possibilities when it comes to setting the control function for both lighting and the appli-ances.

5 These possibilities are covered in detail in the Operating occupancy detectors LUXOMAT PD4 Slave can only be operated in conjunction with a Mas-ter-appliance. Any number of Slave-appliances can be connected up to a Master-appliance for the purpose of extending the area of coverage without incurring significant expense. Slave-appli-ances cannot be set independently. All setting-work is carried out on the LUXOMAT PD4 ' N L - LNO NO3 ASlave/Remote PD4/MPD4/SLUXOMAT SMSurface mountFCCeiling mountFMFlush mount2627 Detecting movementThe motion-detector feature of the installation centres around a visual system which has been designed and developed to an exceptionally high electronic and optical standard.

6 The infrared beam which is radiated from moved or moving objects is directed straight at a pyroelectric Sensor via the hemispherical Fresnel lens. Automatic Light control (PD4 MASTER)FunctionThe Light is switched on automatically in the operating mode Fully Automatic once move-ment is detected and a pre-set minimum degree of brightness (switch-on value) is not achieved, just as it is switched off automatically in the absence of movement or when a pre-set maximum degree of brightness (switch-off value) is exceeded. It is possible to program either the switch-on or the switch-off value.

7 If it is the switch-on value which is pre-set, the detector will calculate the switch-off value automatically, and vice versa. When the system is in the operating mode Semi-automatic , it is always necessary to switch on the Light by hand, either using the switch provided or by remote so far as there is no detection of movement at the same time, the degree of brightness at any giv-en time is indicated as follows with the assistance of Light -emitting diodes (LED s) in the appliance:Appliance identifies bright : LED flashes at a steady rate Appliance identifies dark : LED does not flash at allAdditional information.

8 In order to avoid situations where switching-on and switching-off occurs unnec-essarily, the reaction on the part of the appliance to any change in the degree of brightness is triggered on a time-delayed basis. Passing cloud, for exam-ple, would suffice to cause unnecessary bright dark : 30 secondsTime-delay dark bright : 5 minutesLearning processThe system features a learning process, which enables the detector to take into consideration the fact that the illuminating power of fluorescent lamps is not yet fully developed at the beginning of their service life, and likewise their illuminating power deteriorates with age.

9 Once the switch-on value has been preset, the detector switches on the Light repeatedly for periods of 5 minutes regardless as to whether it has detected any move-ments, and then switches it off again until such time as the fluorescent lamps have developed their full illuminating power. It is, however, also possi-ble to get around having to carry out this process (see Automatic memorizing function of the current twilight value for Light control ).Manual Light control (PD4 MASTER)Regardless of the availability of Light at any given time, the Light can be switched on or off manually using the remote-control facility or a contact switch located at the input R (impulse to sec.)

10 Important: Appliance must be closed (see Clos-ing the PD4 Master ). Switching on using remote control or switchThe Light will remain switched on for as long as movements are detected in the areas of coverage. Once the last movement has been detected, the Light will remain on for the duration of the follow-up time as per setting. The appliance will then return independently to the mode selected. (Fully or Semi-automatic).Where the appliance has already identified the con-dition bright prior to the lighting being switched on manually, the level of brightness will not be moni-tored after switching-on has taken the appliance has already identified the condition dark prior to the lighting being switched on manually, the level of brightness will be monitored after switching-on has taken place.
