| Without
question, the main complaint in the industry with
regard to lightning surge protectors is the difficulty
in determining whether the surge or lightning protector
installed to protect your control system components
is still functional. M-System's latest addition to
their vast variety of surge suppression devices solves
this problem. Lightning
surge protector Models MDM2A and MAA provide 'health
indication' for easy monitoring, maintaining and
verifying the functionality of these control system
protection devices. These lightning surge protectors
include an amber alarm indicator to alert panel
inspectors that lightning surge protector has reached
its useful life and should be replaced before loss
of surge protection. If these units are not replaced
promptly, the alarm indicator changes from amber
to red upon a complete loss of surge and lightning
protection.
In addition to the life monitor
function, this counter function will help you to
gather statistical information on vulnerable spots
throughout your installation, for more efficient
surge protection measures.
Modern day industrial equipment
relies heavily on microprocessor-based technology.
This makes it essential for critical control components
to be protected from lightning, transients and surges.
M-System lightning surge protectors with health
indication operate by monitoring the leakage current
from signal to earth ground. Additionally the number
of suppressed surges is also monitored. When a predetermined
level of either the leakage current or number of
suppressed surges is exceeded, the health indicator
illuminates.
Low in cost, these devices pay for
themselves by providing early warning alarms and
reducing ongoing unnecessary panel maintenance.
To give you an idea of their functionality, consider
opening a panel with a large number of lightning
surge protectors. Instead of unplugging and testing
every unit, for M-System's life monitor series all
that is necessary is a quick visual indication.
No further tools or checking are required!
When it comes to comparing
the cost of downtime versus lightning surge protector
replacement, the choice is obvious.
