Procedure in the event of an error
Possible error
Cause
Remedy
No display
External fuse for the supply voltage was
triggered.
Replace fuse.
No current display.
Measurement voltage not
connected.
Connect measurement voltage.
Measurement current not connected.
Connect measurement current.
Displayed current is too high or
too low.
Current measurement in wrong phase.
Check connection and correct as needed.
Current transformer factor programmed incor-
rectly.
Read out and program the current transformer
conversion ratio on the current transformer.
The peak current value at the measurement
input was exceeded by current harmonics.
Install a current transformer with a larger current
transformer conversion ratio.
The current at the measurement input was
exceeded.
Install a current transformer with a smaller
current transformer conversion ratio.
Displayed voltage is too high or
too low.
Measurement in wrong phase.
Check connection and correct as needed.
Voltage transformer factor programmed incor-
rectly.
Read out and program the voltage transformer
conversion ratio on the voltage transformer.
Displayed voltage is too low.
Measurement range violation.
Use voltage transformer.
The peak voltage value at the measurement
input was exceeded by harmonics.
Attention!
Ensure that the measurement inputs
are not overloaded.
Phase shift ind./cap.
Current path is assigned to the wrong voltage
path.
Check connection and correct as needed.
Effective power drawn/delivered
have been switched.
At least one current transformer connection has
been switched.
Check connection and correct as needed.
A current path is assigned to the wrong voltage
path.
Check connection and correct as needed.
Effective power is too high or too
low.
The programmed current transformer conver-
sion ratio is wrong.
Read out and program the current transformer
conversion ratio on the current transformer
The current path is assigned to the wrong
voltage path.
Check connection and correct as needed.
The programmed voltage transformer conver-
sion ratio is wrong.
Read out and program the voltage transformer
conversion ratio on the voltage transformer.
An input/output does not respond.
The input/output was programmed incorrectly.
Check programming and correct as needed.
The input/output was connected incorrectly.
Check connection and correct as needed.
Display
"Measurement range violation"
There is a measurement range violation
Check connection and correct as needed.
Correct current /voltage transformer conversion
ratio.
No connection to device.
RS485
- Wrong device address.
- Different bus speeds
(Baud rate) and/or data framework
- Wrong protocol.
- No termination.
- Correct device address.
- Correct speed (baud rate).
Correct data framework.
- Correct protocol.
- Connect bus to a termination resistor.
Despite taking the above measures,
the device does not work.
Device is defective.
Send device back to
manufacturer with an
exact description of the error/fault.
