1. INSTALLATION

1.1 Introduction to the Control Panel

The DKG-705 is a control and protection unit used in gensets. The 4 lines by 20 characters LCD

display allows the visualization of many measured parameters. The unit is designed to provide user

friendliness for both the installer and the user. Programming is usually unnecessary, as the factory settings

have been carefully selected to fit most applications. However programmable parameters allow the

complete control over the generating set. Programmed parameters are stored in a Non Volatile Memory

and thus all information is retained even in the event of complete loss of power.

The measurable parameters are:

Mains voltage phase R to neutral

Mains voltage phase S to neutral

Mains voltage phase T to neutral

Mains voltage phase R-S

Mains voltage phase S-T

Mains voltage phase T-R
