'Current limit' and 'Overload level' settings are adjustable. The XFE monitors current in one phase only and this
limits overload currents in accordance with the trip curves shown here (See Menu structure for default settings).
Parameter P106 may be changed to select Class 10B, 10, 20 or 30. This will automatically change the motor
current rating (Trip level) of the unit to maintain over current protection.
Note: The overload monitors one of the phases only and the 'Current Limit' level is only active during motor
starting.
IMPORTANT
It is recommended that the control supply is maintained between starts to ensure the integrity of the overload,
which will reset on it's removal.

Product information
Cooling
The XFE is designed so that the rated start current/time is close to the maximum allowed. If the start duty is
exceeded the unit will trip. All XFE Soft Starts have a forced off cooling time between starts.
In line with the stated IEC starting duties, all XFE 100 series have an enforced off period of 2 minutes, likewise all
XFE 200 and XFE 300 series have an enforced off period of 7 minutes set as standard. During this period the
display indicates
“Stopped.Cooling”
, and the XFE will not respond to a start signal.
AC53a ratings are for Optimising or use without a bypass contactor.
AC53b rating is only for use with a bypass contactor and will trip if one is not used
Trip curves show the nominal times for operation from cold (40°C)
