4. r or simply registrates the information for administration Even the handling of a taximeter can be simplified by usage of the seat sensor system The driver won t ever forget to switch the taximeter to occupied Fraud can be suppressed very easy and in a very efficient way The control unit is capable to control 3 lines that means three rows of seats inside the car The standard state of delivery is with two lines that means two transmitters and two receivers Most recently all car manufacturers modernized their vehicles with safety systems like SRS or even with special children seats in the rear passager seats which made the installation of older seat sensor systems beeing installed inside a seat unreasonable Even crossing the cars safety system with later taxi specific installations is not professional in any way ror tal RX reor RX Manipulation Conventional seat sensors contain always the problem of beeing disactivated by interrupting the lines between sensor and the meter This system controls itself though an intelligent processor It sends data words from the control device which have to be received correctly In case this chain is not closed the control unit reacts by giving the information of occupied state towards the following device O ne of the two outputs is also working like an alarm systems chain It is connected to ground as long there is noone inside the car By changing this state it will open the chain to g
5. round Even if this wire is cutted the information being presented to a taximeter is containing the state occupied The system excludes automatically environmental influences like temperature and it compensates the environmental light Variation effects of light are also being suppressed by the system Functionality For best results of the systems functionality it is necessary to be very careful installing all components and even reading the instructions is helpful to be successful The adjustment of the pots should be made carefully After some installations the installer will get a feeling of what can go wrong installing the sensors Even take into consideration that cars can be very different and the installation times can differ a lot e g when not finding a good possibiliy how to get the cables through the doors rubbers in case there is no additional space for your cable For good performance you need a perfect installation and even a constant supply voltage fulfilling the limitations Consider after working half a day inside a car installing taximeter radio and seat sensor the cars interior light is mostly constantly on and has taken a lot power from the cars battery Afterwards testing the seat sensors sometimes they are working well sometimes malfunctioning you will see the supply voltage of your cars is far below 12 Volts After an installation and before testing the sensors let the engine run for some moments to get a good sta
