UFS8000 System description 2
1.3. Diagram of the unit
The unit is schematically represented in the following diagram
The diagram features all the components defined in the controller. Only the components that are
connected to the available in- and outputs can be displayed.
§ 29 “Terminology” on page 107 offers an overview of the meaning of the abbreviations used..
These abbreviations may differ from the picture, because they have been modified by the user.
1.4. Unit configuration
In the controller the unit configuration can be configured via the menu option “Unit” (in the main menu).
First of all, an inventory has to be made of the components that have to be driven by the controller,
and to which pins these components are connected. The inventory is described in § 5.1 “Inventory” on
page 12.
Subsequent to the inventory any delays, limits etc. can be set for the various components under the
“Programming - Components ” option. This is described in § 6 “Component” on page 17.
Next the various phases (“Filtration”, “Pre Flush” etc.) can be programmed.
The functions that are switched on or switched off can be set for each phase. A time duration may also
be entered. This is described in § 7 “UF Unit” on page 45.
