Controller menu selection. Use
this drop down list to access the
dierent controller menus.
Once all the addresses and custom naming is complete escape
out of the addresses menu and navigate to the ‘Suction’ tab. This
will allow for conguration of the Pack Controller(s). Use the drop
down (Suction) menu to access each Pack controller and the
corresponding menus. Please note that any online controller
devices will invoke a dialog box which asks if you wish to retrieve
the data from this controller. This dialog box is intended to direct
the choice of either uploading data from a controller (overwriting
any previous settings held in the AK-SM database) or not. If you
have existing controllers on the network which have already been
congured, choose the upload option (this need only be done
once for each controller you view).
When to use Upload / Download function:
The AK-SM holds a database in which all the system conguration
is held. This includes any actual controller devices connected or
just devices that have been selected ready for conguration. It is
important to recognise when to perform an upload or download
function so that any preset conguration is not overwritten by
automatic upload by the AK-SM.
Upload
This function may be required where the case and pack control-
lers have already been congured and all parameters are set
according to customer specications. In this instance the need is
to typically perform an upload function, thus updating the AK-SM
database to fully reect the controllers commissioned settings.
Once this has been done, changes to the controller settings can
be done directly from the AK-SM.
Download
The opposite to this would be where the controller devices have
not been set per customer specication and the AK-SM should be
used as the commissioning tool or window into the controllers.
By navigating through all the controller screens in the AK-SM it is
possible to congure the controller parameters and then send
these setting to the connected controllers via the download
function.
