DIP-switch 7 DIP-switch 8direction presence signaldirection pulse signalThe direction pulse signal is normally used for counting systems and the direction pulse signal for gate and barrier controls.At the examples in the next column the operation principle of the direction logic is explained. The direction signal is output via the relay of the first covered loop i.e. signaling occurs in the case of driving direction 1->2 via relay 1 and in the case of driving direction 2->1 via relay 2.In case of failure of one loop during direction output mode the detector operate in presence output mode independed of the setting of DIP-switch 8.a) single vehicle1212121212b) column traffic121212121212121212c) reversing vehicle1212121212DIP-switch 8relay 1 signal onrelay 1 pulserelay 1 signal remainsrelay 1 signal offDIP- switch 8
