Single phase mode not
supported
94 Configuration A voltage module not supporting single phase mode was
configured for single phase mode. Use a voltage module with
production index A5 or later.
U below trip/warn level 95, 96 Motor supply voltage is too low. Check supply side: E.g. circuit breaker, fuses, wiring and the
feeding.
U above trip/warn level 97, 98 Motor supply voltage is too high. Check supply side: E.g. circuit breaker, fuses, wiring and the
feeding.

Configuration
Check that the configured sensor type is correct
Check that the correct sensor type is connected
Check that the delivered sensor signal in range.
P below trip/warn level 116, 117 Active power consumption of the
motor is too low.
Either the motor is idle (not loaded) or the motor load is not
connected because of a broken belt or a dry running pump etc.
Check load side
PF below trip/warn level 120, 121 Active power consumption of the
motor is too low
Either the motor is idle (not loaded) or the motor load is not
connected because of a broken belt or a dry running pump etc.
Check load side
Phase loss (voltage) 122 No voltage on one or more phases.
Possible causes are a blown fuse
or a wire break.
Check fuses
Check wiring on supply side.
Phase imbalance
(voltage)
123 There is a high imbalance on
supply side e.g. because of
unsymmetrical load of the three
phases.
Check supply side especially the fuses and supply line.
Voltage out of range 124 The voltage is out of the specified
voltage range
Check supply side. See 95 – 98.
Wrong Phase Sequence
(voltage)
125 The phases were wired in incorrect
order.
