Lightning Counter ERICO (USA)
The LEC-IVR Lightning Event Counter, part of the ERITECH
®line of facility electrical protection
products from ERICO, registers and records the number of strikes handled by a lightning
downconductor. Based on the proven LEC-IV technology, the LEC-IVR features an output that
allows for remote monitoring of the lightning count activity.
The device consists of a standard LEC-IV counter with an optic fiber output, a length of
interconnecting optic fiber and a remote monitoring device that mounts to DIN rail. The
interconnecting 1,000 μm fiber cable requires no special termination tools and uses simple
push and screw-in terminals.The optic fiber provides galvanic isolation between the lightning
downconductor and the remote monitoring device. Powered from a 9 to 12 VDC supply, the
remote monitoring device provides an easily interfaced relay closure output. Although the relay
output is normally open, it closes for 2.5 seconds to indicate a lightning strike. The clean, pre-
determined-duration contact closure eliminates relay chatter that might otherwise occur.
After the downconductor has been fixed into place, the LEC IVR may be mounted at any
location on the downconductor route between the terminal and grounding system. Choose a
secure area that is not prone to contact with moving objects, theft or vandalism. If the LEC-IVR
is to be encased in an additional enclosure, ensure that it is mounted to enable easy access to
the display. The LEC IV can be mounted at any point on the downconductor or at the injection
point of the grounding system
