Updates to the instruction manual

The majority of the modifications to the instruction manual are related to the new navigation

sequence and front panel keys for browsing through setpoints, actual values, and target messages.

The content of the manual was also improved to enhance the understanding of the product.

Chapter 1 was modified for the new navigation process reflecting the additional MESSAGE keys, the

introduction of the MENU key, and the elimination of the NEXT, SETPOINT and ACTUAL keys. Additional examples were introduced to illustrate the navigation process and how to access setpoints,

actual values, and target messages. The application example was enhanced, providing additional

background and adding wiring diagrams, connection diagrams, and control schematics.

The order code, as well as the examples, was modified in chapter 2.

Chapter 3 was updated with illustrations of the new product.

In chapter 4, the drawing showing the relay faceplate was updated to reflect the new faceplate

design. The format of the diagnostic messages was changed to reflect the new presentation. The

sections that covered the PC software was replaced with a new section corresponding to the enerVista 750/760 setup software.

Chapter 5 was modified to reflect the new navigation process. All navigation instructions for setpoints were reviewed and changed accordingly. The section corresponding to the Automatic Transfer Scheme was enhanced. Due to the keypad changes, the key sequence for clearing maximum

and last demand values was changed from ìSetpoint, Decimal, Message Upî to ìMenu, Decimal,

Message Leftî.

Chapter 6 was also modified to reflect the new navigation process.

The communications chapter (Chapter 7 in the previous manual) has been removed. This information is now available as GE Publication number GEK-106473: 750/760 Communications Guide.
