Protection

The LGC is protected by internal solid state
Polyswitches on the incoming power and
network lines. These Polyswitches are not
replaceable and will reset themselves if the
condition that caused the fault returns to
normal.

Production Date

To determine when a module was
manufactured, check the Module Status
report in SuperVision. Refer to the SuperVision
User's Guide for more information about the
Module Status report.
A sticker on the back of the module also
shows the date the module was
manufactured. The first three characters on
the sticker indicate the type of module. The
next three characters show the year, month,
and week of manufacture. (The month digit is
in hexadecimal.)
