Possible error
Active power
too
small or too large.
No connection
with
the device.
Despite the meas-
ures above the device
does not work.
Cause
The programmed current
transformer transformation
ratio is incorrect.
The current path is assigned
to the wrong voltage path.
The programmed voltage
transformer transformation
ratio is incorrect.
RS485:
- Device address is incorrect.
- Wrong protocol.
- Different bus speed.
- Termination missing.
RS232
- Device address is incorrect.
- Wrong protocol.
- Different bus speed.
- The concealed key
(service) was used.
Device is defective.
Remedy
Read out and program the current
transformer transformation ratio at the
current transformer.
Check connection and correct if
necessary.
Read out and program the voltage
transformer transformation ratio at the
voltage transformer.
Adjust the device address.
Correct protocol.
Correct speed (baud rate).
