ALWAYS ENSURE THAT THE KEYPAD CABLE IS PLUGGED IN BEFORE APPLYING POWER TO THE UNIT
When wired as Fig 2.1,page 3, the XFE
display will indicate start up messages
followed by ‘Stopped and ready’. At this
point:
• the XFE will start the motor when
the keypad ‘START/STOP’ key is
pressed but not when the START
switch as shown in Fig.2.1 is closed.
• the XFE parameters are set to
factory default which may not be
ideal for the required application.
The examples in section 4 show how to
set up some of the essential XFE operating
parameters using the keypad. Once these
are understood, other XFE settings, as
indicated in the programming Menu
Structure, can be set in a similar manner
(The corresponding default settings are
shown in brackets). For the full menu
structure see page 6 .
XFE Soft Starts are either supplied pre-set to a Start Class or ready to set. An appliction selector chart is available
from FE to aid in the selection of the correct XFE. If the unit is supplied ready to set then it will force the selection
of a starting Class when first powered up.
It is always possible to change the starting Class through menu item >Advanced > current > P106 start class
When the motor is running the XFE can display current (default) or Estimated Power. Pressing the # key at the
top of the menu structure allows the user to toggle between these 2 options.
Starter Enable/Disable
An additional safety feature has been added so that following certain actions the XFE will be disabled. It is
strongly recommended that before any changes to parameter values are made, that the XFE is disabled via the
Basic Menu. Once disabled, the XFE remains unable to drive the load, until it has been enabled via the Basic
Menu, or the control supply is removed and reapplied, or the key is pressed when prompted.
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
