Operation
Surge protection electronics tolerate a number or frequency of activations at given voltage
levels until they eventually fail. During this time, the surge protection electronics gradually
degrade. The integral diagnostic function compares the overvoltage events to a given
algorithm. This way, the function can predict how many more overvoltage events are tolerable
until the surge protection electronics has reached the 'end of effective life'. Once this point has
been reached, the diagnostic function issues an alarm to the Pepperl+Fuchs Advanced
Diagnostics infrastructure. The alarm is transmitted to the Pepperl+Fuchs 'Advanced
Diagnostic Manager' software running on the system maintenance or operator workstation.
Additionally, the Surge Protector issues a visual alarm to help identify the failing unit or units
quickly.
For detailed information, refer to the respective Surge Protector(s) manual(s).

Accessory: Enclosure Leakage Sensor ELS-1

The FieldConnex
water ingress breaches inside housings early. ELS–1 warns of water ingress before it can
adversely affect fieldbus communication, demand high current levels or cause galvanic
corrosion damage to electronics. Compactly designed ELS–1 fits into most of today's existing
field device housings.
The sensor is designed for use in fieldbus communication topologies according to
IEC 61158–2. ELS–1 conforms to the intrinsically safe FISCO and Entity concepts and to
IEC 60079–11. As an associated apparatus, ELS–1 can be attached to any fieldbus trunk or
spur that is intrinsically safe certified.
ELS–1 can be connected in parallel to the spur output cables of Pepperl+Fuchs device
couplers types R2-SP-IC*, F2-SP-IC*, and R4D0-FB-*. Powered by the spur, ELS–1 requires
less than 6 mA for operation.
Once water is detected, the diagnostic function inside ELS–1 issues an alarm to the
Pepperl+Fuchs Advanced Diagnostics infrastructure. The alarm is transmitted to the
Pepperl+Fuchs 'Advanced Diagnostic Manager' software running on the systems maintenance
or operator workstation.
