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)

•
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
