How do I program delay or extend times on the LMD222?

The video below explains how to configure and troubleshoot EDI LMD Series inductive loop detectors, covering sensitivity, frequency, output modes, and open/short circuit faults.

• Sensitivity: Set each channel to a suitable level using a standard passenger car over the loop. Confirm the detector activates reliably.

• Frequency: Select from four frequency settings. Keep nearby loops sufficiently separated in frequency (the presenter recommends roughly 5–10% difference) to reduce cross-talk.

  Output modes:

  • Short: Presence detection up to 30 minutes.
  • Long: Presence detection up to 120 minutes.
  • Pulse: Brief output pulse of approximately 100–120 milliseconds.
  • Call: Continuous detection output, regardless of vehicle presence.
  • Off (–): Disables the detector.
• Fault detection: An open circuit triggers a fault indication and continuous call to the controller. A short circuit also triggers a fault.
• Fault reset: Restore the wiring, then press Mode + Frequency simultaneously or power-cycle the detector to clear the fault history.
