Under-Voltage Alarm [433]
In this menu group the settings for an undervoltage alarm are
selected.
Under-Voltage Alarm Action [4331]
In this menu the alarm action for the undervoltage alarm is
selected. The following alarm actions are available:
Under-Voltage Level [4332]
Here the voltage level for an undervoltage alarm is entered,
expressed as a percentage of the nominal motor voltage. As
soon as any line voltage falls below this voltage level for a time
period equal to the set delay time in menu [4333], an
undervoltage alarm will occur and the action selected in
menu [4331] will be executed.
Under-Voltage Alarm Delay [4333]
In this menu the response delay for the voltage unbalance
alarm, as set in [4431] and [4432], is selected
Phase Reversal Alarm [434]
If this function is activated, an alarm will be issued if the
wrong phase sequence is detected prior to a start.
Phase Reversal Alarm Action [4341]
In this menu the alarm action for a phase reversal alarm is
selected. The softstarter will detect the phase sequence prior
to each start attempt. If the actual phase sequence does not
match the allowed phase sequence set in menu [4342], the
action chosen in this menu will be executed.
To enable the phase reversal alarm, a motor has to be
connected and the mains voltage has to be switched on. The
alarm is only valid at starting attempts.
Allowed Phase Sequence [4342]
In this menu the allowed phase sequence is selected.
