Questions during commissioning
1)
“AUTO”
is not displayed

control stopped or switched off.
Possible causes:
Manual operation, control has been stopped or switched off in the setup menu.
Current is less than 5 mA, voltage of THD of voltage or current are out of tolerance, temperature is too
high, “Automatic initialisation (AI)” was cancelled with an error notification.

Control is switched off
2) Display
“U ALARM” 
measuring voltage out of tolerance
Possible causes:
Over- or under-voltage in the system, the set nominal voltage and the voltage transformer factor do not
correspond to the system.
Solution:
Check the settings for nominal voltage (SETUP/100/Un) and voltage transformer
(SETUP/100/Pt). The set voltage tolerance range is too small.
Solution:
Check the settings of the tolerance range (SETUP/204).
3) Display
“I Lo ALARM”

no current
Possible causes:
Connection from the current transformer to the controller is not correct; current transformer jumper is
not removed; transformation ratio of the transformer is too large

current is less than 5 mA

no
current
4) Display
“EXPORT” 
feeding back of active power
There is no real feeding back, please check the connection of measuring voltage and current (phase,
polarity).
Possible causes:
The set phase correction angle does not correspond to the connection of measuring voltage and current.
Solution:
Correct the connection, execute the
“Automatic initialisation (AI)” or manually set the phase
correction angle correctly.
