Fieldbus Surge Protector
Product Specifications
Surge protection electronics can tolerate a given number or frequency of activations at given
levels of voltage, before they completely fail, during which time, the surge protection
electronics will gradually degrade. The diagnostic electronics will log and compare
any activation to an algorithm that will then decide if the surge protection electronics
is reaching its
‘
end of effective life
’
. At this point, the diagnostic electronics generates an alarm
that the Fuchs Advanced Diagnostics infrastructure receives, whereon this alarm will
be transmitted to the system
’
s maintenance or operator terminal, containing Fuchs
Advanced Diagnostic Manager software. Additionally, at the Surge Protector, a visual alarm
is given so that the failing unit, or units, can be quickly identified.

Status and Error Messages
The Surge Protector types *-LBF-IA1.36.*.1 incorporate a LED showing the health or status
of the Surge Protector. A green flashing LED indicates that the Surge Protector is healthy.
An overvoltage event will be shown as a single flash event of the red LED.
During power up, Surge Protectors with integrated diagnostics show the percentage
of the headroom of surge events already used, before the Surge Protectors issue an alarm.
Each single flash represents 10 % of used headroom. If the LED shows 10 consecutive red
LED flashes, the exchange of the Surge Protector is required at some point before the next
expected surge event.
2.1.4
Compatibility for Surge Protector Diagnostics
This predictive maintenance feature for the Surge Protectors is available in combination
with the fieldbus coupler types R2-SP-IC*, R4D0-FB-IA*, and the Advanced Diagnostic
Module type HD2-DM-A. Using the Surge Protectors in combination with the fieldbus coupler
R2-SP-N*, a green/red LED locally on the device indicates the diagnostic information;
in this instance, the diagnostic information is not transmitted to the Advanced Diagnostic
Module.
