Update notice
Cause
x High AC voltage measured long
enough
x High AC voltage peak
x Supply voltage out of RT-area.
Missing phase(s) or frequency out
of the allowed range for 20 seconds
during synchronization.
x AC voltage is lower than
U/Un LEVEL1
MPPT has reached the DC
x
reference minimum range.
x MPPT has reached the DC
reference maximum range.
x Cut-in conditions are not fulfilled.
x Error in the adaptive program
x Error in the RDIO module or module
configuration
x NAMU grid monitoring has alarmed. Check group
What to do
Check parameters

TIME.
Check parameter
PEAK.
Check RT-area parameters
40.10...40.15.
Check network conditions.
Check that initialized base

correct.
40.10 RT Alarm is cleared when the AC
voltage is greater than
Un LEVEL1

Check the settings of parameters
44.18...44.22.
Check the adaptive program for
errors. Check parameters
57.01...58.05.
Check that configuration for the
RDIO modules is correct in the

MODULES. Replace the RDIO
module if the alarm is continuously
active.
