Message
Fault
Action
Locked, Alarm LED on
Lock input activated
Unlock
Switch not in AUTO
mode, Alarm LED on
Slide switch is in handle
or lock position
Turn slide switch into
the AUTO position
Phases crossed
Phase rotation of sources 1
and 2 are different
Connect the phases of both sources in
the same order
S1 undervoltage
Voltage of source 1 is under the
threshold level set in parameter
“Dropout voltage, lower threshold“
Check the correlation between power
source and device configuration
S1 overvoltage
Voltage of source 1 is over the
threshold level set in parameter
“Dropout voltage, upper threshold“
Check the correlation between power
source and device configuration
S1 phase missing
One or two phases of
source 1 are missing
Check the power source
and connections
S1 unbalance
Phases of source 1 are not symmetric
Check the power source
S1 phase rotation
Phase rotation of source 1 is
different from the value of
parameter “Phase sequence“
Connect the phases according to the
configuration
S1 invalid frequency
Frequency of source 1 is out of range
set in parameters “Drop-out frequency,
upper threshold“ and “Drop-out
frequency, lower threshold“
Check the correlation between power
source and device configuration
S2 undervoltage
Voltage of source 2 is under the
threshold level set in parameter
“Dropout voltage, lower threshold“
Check the correlation between power
source and device configuration
