6.1 Alarms
Alarm condition 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
