Description
LPI Lightning Strike Recorder
LPI® Lightning Strike Recorder (LSR2) is a lightning event counter. The LSR2 is simply mounted at any location along the down-conductor route. Its purpose is to record the number of lightning strikes captured by the lightning air terminal and conveyed by the down-conductor. The LSR2 operates by sensing current by means of an inductive pick up loop. The loop passes along the inside surface of the bottom of the enclosure. This loop detects lightning current impulses on the down-conductor and sends a trigger to the counter, which turns the counter over to register the event. The Recorder is mounted in a polycarbonate enclosure rated IP 65.
- To test the LSR, the supplied ‘pulse cable’ is positioned parallel to the down-conductor, through the mounting saddles as shown in Figure 3.
- Complete the loop around the LSR, making sure that pulse cable is positioned vertically across the top of the LSR as shown in Figure 4.
- Holding down the red button initiates the impulse circuit charging and firing process. Correct charging operation is indicated by the illumination of the red LED, as shown in Figure 5.
- After a period of 10-15 seconds an audible ‘clunk’ should be heard. This indicates that the charging process has finished and a current pulse has been sent through the pulse cable.
If the LSR and LSR Tester are working correctly, the strike count on the LSR will increase by one (1).
If the LED fails to light when pressing the red button, or if no ‘clunk’ is heard after a period longer than 30 seconds then the batteries need to be recharged using the supplied charger. The charger unit has two indication LEDs to indicate charger power and charging status.
Press and hold the charging button for up to 1 second to start charging the battery. The LED will indicate RED. Once a battery has been fully charged, the charging LED will turn GREEN.
Cara Pemasangan
LSR2 akan terpasang pada lokasi kabel konduktor antara head penangkal petir ke grounding dengan posisi sebagai sistem penghitungan arus dari sambaran petir menuju ke bumi sehingga bisa.
