17.6 Procedure in the event of errors
Possible error Cause Remedy
No display External fuse for the power supply voltage
has tripped.
Replace fuse.
No current display Measured voltage is not connected. Connect the measured voltage.
Measurement current is not connected. Connect measurement current.
Current displayed is
too large or too small.
Current measurement in the wrong phase. Check connection and correct if necessary.
Current transformer factor is incorrectly
programmed.
Read out and program the current
transformer transformation ratio at the
current transformer.
Current harmonics exceed the current peak
value at the measurement input
Install current transformer with a larger CT
ratio.
The current at the measurement input was
not achieved.
Install current transformer with a smaller
current transformer ratio.
Voltage displayed is
too large or too small.
Measurement in the wrong phase. Check connection and correct if necessary.
Voltage transformer incorrectly
programmed.
Read out and program the voltage
transformer ratio at the voltage transformer.
Voltage displayed
is too small.
Measurement range exceeded. Install voltage transformers.
The peak voltage value at the measurement
input has been exceeded by harmonic
components.
Attention!
Ensure the measurement inputs
are not overloaded.
Phase shift ind/cap. Current path is assigned to the wrong
voltage circuit.
Check connection and correct if necessary.
Active power is too
large
or too small. *
The programmed voltage transformer ratio
is incorrect
Read the current transformer ratio on the
current transformer and configure it again
on the device.
A current path is assigned to the wrong
voltage circuit.
Check connection and correct if necessary.
The programmed voltage transformer ratio
is incorrect
Read the voltage transformer ratio on the
voltage transformer and configure it again
on the device.
Active power
consumption/export
is reversed.
At least one current transformer connection
is reversed.
Check connection and correct if necessary.
A current path is assigned to the wrong
voltage circuit.
Check connection and correct if necessary.
An output is not
responding.
Incorrectly connected output. Check connection and correct if necessary.
“StG onE“ in the
display
Firmware update failed.
Renew firmware update via the GridVis
®
software.
"EEE" in the display See error messages.
No connection
to the device.
Incorrect device address Correct device address.
Different bus speeds (baud rate) Correct speed (baud rate).
Incorrect protocol. Correct protocol.
Termination missing. Connect bus with termination resistor.
Device still does not
work despite the
above measures.
Device defective. Send the device to the manufacturer for
inspection and testing.
* If the max. total energy value is reached, the display “0” appears.
NOTE
Property damage due to overloaded measurement inputs!
Too high current and voltage values overload the measurement inputs and can damage the device.
Observe the threshold values specified on the rating plate and in the technical data of this
manual.
