1 System Design of UA 300 D
The UA 300 D Case Controller is a component of the new LDS System. It is based on the hardware of the
UA300 Case Controller and has been designed for application in discount stores. The controller is a package unit
without optional expansion modules. A BT 300 x Operator Interface can be connected to the controller when re-
quired. Electrical connections are described in Section Pin and Terminal Assignments of UA 300 D.
