1 General The Transmitter/Receiver Single Feeder 4 (SF4) is a re-design of the SF2 and can be used for identifying of ISO FDX en HDX responders. SF4 compared to SF2 The SF4 print is based on the SF2. Cable connections are the same as with a SF2. When using HDX and ISO operation a synchronisation cable must be installed. Most important change is that FDX and HDX responder types can be identified according to the full ISO standard 11784 and 11785.
3 Installation The Nedap guarantee-regulations are only valid when the SF4 is installed as indicated in this manual. The following is important : Technical specifications Single Feeder 4 Input voltage Max.
Synchronisation for HDX A synchronisation cable is necessary for HDX to synchronise T/Rs that can influence each other. For FDX only (jumper set to FDX only) synchronisation is not necessary. SYNC SYNC SYNC The connector at the right hand side (SYNC) contains a synchronisation signal for HDX (SYNC). SYNC has to be connected to all other HDX Single Feeders in the neighbourhood. There is no + or -. Maximum number is 16 that can be connected together for synchronization.
4 Set Address For communication the Transmitter / Receiver needs an address. Then the computer knows where to send the information to. At the transmitter / receiver with help of the display and the push button the stations address is configured. The two segment display and the yellow push-button must also be used for several adjustments of the Transmitter / receiver. A number of different codes will appear on the display when the push-button is pushed, these codes represent the so-called menus.
5 Adjust antenna The antenna adjustment has to be done with help of the display, push button, potentio meter (P1) and a coil (L404) on print (or EWA transformer when using external antenna).
Power adjustment After correct processing the antenna adjustment procedure, P1 (fig1) must be adjusted with help of AP. Power adjustment is used to set the ID distance. By reducing the power the reading distance will be smaller. Power adjustment is done with a potentiometer (P1). Changing the power level: Select with the push button the AP-menu (adjust power) and press untill the display starts to blink. A value appears on the display now. Turn P1 till the desired reading distance of the ID label.
6 Adjust Neutrodynisation Why using a neutrodynisation unit When two large antennas are used in a small area, a responder identified in one antenna, is also identified in the other antenna (cross talk). Installing a neutrodynisation unit can solve this problem max 00 9835733 00 9835733 9836080 1 2 Figure : Single Feeder model 4 with neutrodynisation Principle of neutrodynisation The neutrodynisation-unit is a small version of the big antennas.
Adjustment of the neutrodynisation unit Single Feeder model 4 IMPORTANT : Always use a synchronisation cable between both T/R. 1. Switch on the power to the system 2. Position both neutrodynisation-coils close to each other, but not touching 3. Antenna 1 : Select “An” on the display, then “nt”, press until display blinks. The display now shows “tt” (transmitting) Antenna 2 : Select “id” on the display, press until display blinks. The display now shows a numeric value (receiving) 4.
6 Display values During operation, the program steps through different program-states which are monitored on the display. This gives information about the state of the T/R and therefore can be used as an extra service tool.
7 Internal test menu The Internal test menu is a powerful service tool in case of system-service. The T/R stores registered errors which can be displayed on demand of the trouble-shooter. Also the T/R can execute a complete self test on demand, the test results also are displayed. Internal test menu − display Error procedure − Self test menu : see figure 2 Display error procedure The detected errors are stored by the T/R itself and can be monitored on the display.
