Page 7: Introduction
Introduction 1. Introduction The PG 674 is a small, handy device with a keyboard and two- line display. It is used for operating the electronic cam control units Posi Control KUAX 674 and KUAX 673. It is separated from the cam control unit to allow variable use. It can be con- nected with the cam control unit via the programming interface at any time, even when the machine is running. - Page 8 The present operating manual exclusively describes the hard- ware of the PG 674 and how you use it to operate controllers. The control devices themselves are described elsewhere: Controller...

Operating terminal PG 674 3.2. Hand-held terminal PG 674 (674.001.00) The hand-held terminal can be connected to and disconnected from the cam control unit during operation. The connecting cable is firmly attached to the hand-held termi- nal. It serves both communication with the cam control unit and supplying power to the hand-held terminal (24 V DC), which are supplied by the cam control unit. -

Page 29: Choosing A Program
Programming 4.6.7. Choosing a program The cam control unit can store several programs: - KUAX 674: programs 0...7 - KUAX 673: programs 0...31 You can always select one of these programs for programming and/or operation. Apart from the actual programs, the operating terminal has its own program memory which is addressed under number 32. - Page 30 The PG 674 as a programmimg device To give access to program selection in restricted mode Anyone with access to the operating terminal should be able to change programs no matter what operating mode is set. This can be of significance when it is necessary to change programs frequently without problems occurring.
