3 Keypad operation and basic set-up
ALWAYS ENSURE THAT THE KEYPAD CABLE IS PLUGGED IN BEFORE APPLYING POWER TO THE UNIT
When wired as Fig 2.1,page 3, the QFE display will indi-
cate start up messages followed by ‘Stopped and ready’.
At this point:
•
the QFE 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 QFE 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 QFE operating parameters using the keypad.
Once these are understood, other QFE settings, as
indicated in the programming Menu Structure below, can
be set in a similar manner (The corresponding default
settings are shown in brackets). For the full menu structure,
refer to the QFE Manual.
*1 The “Firing mode” must be set to ‘1’ for the In-Delta configuration.
*2 The “Cooling time” is dependant on the Model range, Duty rating and Heatsink temperature.
*3 The “Rated current” setting is for reference only and is not user adjustable.
Selects or deselects optimising (provided keypad control is selected).
Returns user to previous menu level and
cancels any changes made to settings.

or increment a setting value.
Allows user to move down a menu
group or decrement a setting value.

any changes made to settings.
