6 Self-Supervision
The protection devices apply various check routines during normal operation and during the
start-up phase to supervise themselves for faulty operation.
Self-Supervision within the devices
Supervision of... Supervised by... Action on detected issue...
Supervision of data consistency after
an outage of the power supply (e. g.
outage of the power supply while
changing the parameter settings).
An internal logic detects corrupt data
after an outage of the power supply.
If the data is corrupt, all software-
based protection modules are
stopped, and the device continues
with the backup protection.
Parameter Setting (Device) Smart view carries out plausibility
checks to protect the parameter
settings.
(For the settings via DIP or HEX
switches there is no need for any
plausibility checks.)
A problem within the parameter
con󰊟guration can be detected by
means of plausibility checks.
Detected implausibilities are
highlighted by a question mark symbol
on the DiggiMEC and within Smart
view.
Quality of the power supply A hardware circuit ensures that the
device can only be used, if the CT-
based power (or the external power
supply, if available) is in the range
speci󰊟ed by the technical data.
If the supply voltage is too low, the
device does not start, or it stops
operating.
If the voltage is su󰊡cient for the
WIC1, but not enough for loading
the capacitors of the trip impulse
output, then the green “Ready” LED
(DiggiMEC: “System” LED) ceases to
shine.
Internal data of the device (memory
load, internal resources, ...)
An internal module monitors the
system utilization.
The module for the supervision of
the system utilization initiates in
case of a fatal error a reboot
of the device. Some fault types
are indicated via the System/Error
LED, see ╚═▷ “The »System« LED(s) –
“Ready”, “Error””.
(Please refer to ╚═▷ “10
Troubleshooting”.)
The issue will be recorded as a system
message.
An externally supplied WIC1‑4 allows for connecting an external output relay that
operates as a “Healthy” / self-supervision contact. See ╚═▷ “3.7.1 Self-Supervision
Contact for the WIC1‑4”.
