Description
   LDP loop detector is well suited to be used in parking, drive through and car access control applications to control barriers, gates, bollards and car access equipment. Automatic frequency tuning and easy sensitivity adjustment enable easy setup and installation. Automatic sensitivity boost ensures high bed vehicles are detected reliably.

Main features
• Loop input inductance: 20 μH to 1000 μH
• Adjustable sensitivity in 10 steps: 0.01% to 1.00% via
   potentiometer
• Automatic loop frequency tuning or manual tuning via 4
   adjustable loop frequency channels to avoid crosstalk
• Automatic Sensitivity Boost (ASB) for high bed vehicle
   detection
• Selectable fail safe and fail secure mode
• 2 x SPDT relay outputs, selectable operation as pulse or
   presence switching
• Multicolor power/fault LED indication for easy setup and
   intuitive diagnostic
• Individual loop state multicolor LED to indicate different
   loop status and fault.
• Loop diagnostic capability: loop short circuit, loop open
   circuit, inductance out of range, channel crosstalk.
• Directional logic for dual loop.
• Wide range power supply: 24-240 VAC/VDC, 45-65 Hz
