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

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:

Troubleshooting – Parameter Settings
Problem or maloperation in… Problem Description Corrective Action
Transfer of device parameters from one protection
device to another of the same type (e.g. MCA4).
You have configured the parameters of a
HighPROTEC device. Now you want to transfer
these parameters to another relay. This is
possible, if both relays are of the same type, e.g.
MCA4.
Read out the device parameters with Smart view from the
first relay. Save them into a file.
Now reopen this file with Smart view. Adapt the settings to
the order code of the second device <Edit/ Modify Device
Configuration (Typecode)...>. Select <Apply>. By this the
existing parameter file is being converted to the format of
the second device.
Now there may be implausible parameters. They are
marked with a question mark. These are not valid for this
device type. Please adapt the values of these implausible
parameters. Afterward you can transfer the parameter
settings to the second device.
