Self Supervision within the devices
Protecting the parameter setting by
plausibility checks.
A hardware circuit ensures that the
device can only be used, if the power
supply is in the range specified by the
technical data.
Short-term sags of the supply voltage
are detected and can be bridged in
most of the cases by means of the
integrated buffer within the power
supply hardware.
This buffer also allows the termination
of ongoing data writing procedures.
An internal module monitors the
system utilization.
The projected and activated SCADA
module supervises its connection to
the master communication system.

Implausibilities within the parameter
configuration can be detected by
means of plausibility checks.
Detected implausibilities are
highlighted by a question mark
symbol. Please refer to chapter
parameter setting for detailed
information.
If the supply voltage is too low, the
device will not start up or it will be set
out of service respectively.
The module for the supervision of the
system utilization will detect repetitive
short-term sags of the supply voltage.
The module for the supervision of the
system utilization initiates in case of a
fatal error a reboot of the device. In
case of minor faults the system led will
flash alternating red and green
(please refer to the trouble shooting
guide). The issue will be recorded
within an integrated fault memory.
You can check if there is active
communication with the master
system within menu <Operation/
Status display/ Communication>.
In order to monitor this state you can
assign this status onto an LED and/or
an output relay.
For details on the status of the
GOOSE communication please refer
to chapter IEC61850.
