5.4 Setup Examples
This section holds common programming examples that any customer might wish to use.
They explain how to set up the QFE for common tasks. Further, more advanced examples
are given in section
5.5.2 and following.
5.4.1 Enabling and Disabling the QFE
In this software release, the QFE has an additional safety feature, the Enable/Disable
parameter; the effect of this parameter is that the user cannot start the QFE (
running the
motor ) without enabling the unit first.
Whenever the control supply to the QFE is turned on, the unit powers up in an enabled
state. The display will tell the user if the unit is enabled - if it is enabled the display will look
like this;
or whether it is disabled, when the display will look like this;
If the unit has been disabled, there are two ways to enable the unit; one by pressing the
down button when presented with the
Start Disabled
screen above, and the second by
following the instructions below.
With
Starter Disabled
on the screen, press the
Enter
button once. Press the
down button three times until
Basic
is on the top line of the display. Press the
Enter
button once, and with
Disable Starter?
showing press the down button once until
Enable Starter?
is on the top line of the display. Press the
Enter
button once and the
display will flash once confirming the change
There is only one menu-driven way to disable the unit, and that follows the same
procedure as above, except choosing
Disable Starter?
at the point where
Enable
Starter?
was chosen.
There is another situation in which the user may need to disable the starter, that is
when trying to write to a parameter to which write access is denied when the unit is enabled.
Given such a situation (for instance, trying to load default parameters), the unit will ask the
user whether he/she wishes to disable the starter. The user must then reply with the
Hash
( # ) button to answer no, and the
Enter
button to answer yes. Note; if the QFE is disabled
whilst running the load, it will stop running the load as soon as it is disabled.
