Self-supervision Messages
The protection device supervises its normal operation by executing various self-supervision checks during runtime of the device.
When detecting any serious faults, the system LED will start flashing alternating red and green. The issue will be recorded in an internal memory.
Please check the self-supervision messages under <Operation/ Self Supervision/ Messages>.

supply is faulty.
Please check the supply voltage. If it is OK, send the device
to be repaired.

No error.
The device is in its start-up phase.
When the System LED switches to
constant green, the protection
functions are active.
No action necessary.

protection functions are working.
The internal self-supervision module
has detected a serious problem in the
system. The issue will be recorded
within an integrated fault memory.
Please refer to chapter “Self-supervision Messages”.

The device´s HMI is not operable.
There are no Softkeys shown on the
panel. Instead the panel shows
„Startup“ or just the device type (e.g.
MCA4) without any Softkeys.
The device is starting up. The
protection functions are already
working, but the HMI is still starting up.
If this is not finished after 5 minutes,
the device is probably busy with
handling Ethernet packets (Connector
X100).
Check if the following action makes the device´s HMI
operable:
Plug off the Ethernet (Connector X100). Is the HMI now
operable, there is an error on your Ethernet network (e.g. an
Ethernet storm). Please check your network traffic.
The HMI is not operable. A normal
page of the HMI is visible: Either
there are Softkeys visible or the LED
status page is being displayed.

The protection functions are working.
Plug off the Ethernet (Connector X100). Is the HMI now

Should this action not change the device´s behavior, please
read the next entry of this table.

Troubleshooting – Hardware
Problem or maloperation in… Problem Description Corrective Action
Failure of the display After selecting any key, the whole display
remains dark or the display is defective.
Check the following issues:
•Is the supply voltage connected? This is the case
when the System-LED is illuminated
•Is the environmental temperature within the
allowed range?
•Try to adjust the contrast of the display by using
Smart view (increase/ decrease).
If these checks do not show any results, send the relay
back to the manufacturer.
Failure of a binary output
(Also refer to: ”Binary outputs do not react“)
The physical status does not match the reported
state. Check the reported state of the binary
output with the HMI or Smart view.
Check the following issues:
•Is the binary output in the latched state?
Acknowledge the state if necessary.
•Is <Inverting> parameter of the binary output set?
•Check the wiring.
•Plug off the wiring from the binary output and
measure its output. Set the state of the binary
output by using the test functions Force/Disarm.
If these checks do not show any results, send the relay
back to the manufacturer.
Failure of a digital input The physical status of a digital input does not
match its reported state. Check the reported
Check the following issues:
•Is the configured voltage level set correctly?

Problem or maloperation in… Problem Description Corrective Action
state of the digital input with the HMI or Smart
view.
•Is the voltage level of the digital input (signal level)
correct?
•Is the parameter <Inverting> set?
•Check the wiring.
If these checks do not show any results, send the relay
back to the manufacturer.
Wrong setting of the device´s clock after a shortage
of the supply voltage
The internal battery for powering the clock is
empty or defect.
The relay is also working properly with an empty clock
battery. The device´s time can be synchronized. Please
contact the service team.
Failure of a key Send the relay back to the manufacturer.
Line Differential: Failure of the Fiber optic port You want to verify the correct functionality of the
relay's fiber optic module.
Do a Loopback Test:
•During this test the device receives and interprets
its own data as data coming from the remote
device. Therefore the differential protection
modules, the Transfer Trip module or the Signal
Transfer module might trip during the Loopback
test. Therefore we recommend that you block
these modules (or their trip commands) during the
test.
•Build a short direct connection between the RX
and TX port of the device.
The device's fiber optic module is functional, if:
•the device displays <Loopback> under
