LD202 24V Dual Channel Boxed Loop Detector Applications Typical applications in the parking and access control environments are safety loops for barriers or gates, arming loops for activating card dispensers, vehicle counting with direction logic. Features. Reset Switch. Pressing the reset switch enables the detector to be manually reset during commissioning and testing. This results in the detector re-tuning the sensing loop and becoming ready for vehicle detection. Switch selectable Sensitivity. The detect sensitivity is the minimum change in inductance required to produce a detect output. (%∆L/L). Eight sensitivity settings are available on the switches to allow flexibility in configuration. Switch selectable Frequency. The frequency of the loop is determined by the inductance of the loop and the frequency switch setting. If the frequency switch is on, the frequency is reduced. It may be necessary to change the frequency to prevent cross-talk between adjacent loops on different detectors. Selectable N/O or N/C relay output. Internal jumpers enable the output relay contacts to be configured for normally open or normally closed contacts. Extend Option. When switched on this feature extends the presence output relay for 2 Seconds after the vehicle has left the loop. Direction Logic. This feature enables the detector to give a pulse output on relay1 for a vehicle travelling from loop1 to loop2 and a pulse output on relay2 for a vehicle travelling from loop2 to loop1. To enable this feature switches 2 and 4 must be on, and switches 3 and 5 must be off. Pulse Relay Selection. The detect relay may be configured for a pulse output, and to energise on detection of a vehicle or when the vehicle leaves the loop.
