Following the details of the adjustable alarms:
Current
unbalance
Unbalanced of current on phases L1-L2-L3,
in comparison to the average.
Adjustment range = amplitude 5% - 100% In
Delay: 1-20s
Volatage
unbalance
Unbalance of voltage (between phases and neutral, with
internal / external neutral), in comparison to the average
Adjustment range = amplitude 10-400V
Delay: 1-20s
Min. voltage
Minimum measured voltage (between phases,
if 3P device, or between phases and neutral,
if 4P with internal / external neutral)
Adjustment range = amplitude 90-540V
Delay: 1-20s
Max. voltage
Maximum measured voltage (between phases,
if 3P device, or between phases and neutral,
if 4P with internal / external neutral)
Adjustment range = amplitude 120-690V
Delay: 1-20s
Current max
Maximum phases current measured
(for load management)
Adjustment range = amplitude 50% -120% In
Delay: 1-20s
Power max
Maximum active power measured
(for load management)
Adjustment range = amplitude 100kW÷14MW
(limits depend on In)
Delay: 1-20s
Max. frequency
Maximum frequency measured
Adjustment range = amplitude 45-65 Hz
Delay: 1-20s
Min. frequency
Minimum frequency measured
Adjustment range = amplitude 45-65 Hz
Delay: 1-20s
Line phases
rotation
Wrong phase sequence
(rotation among phases different from L1 L2 L3)
