and only the key functions such as tripping are connected to the outputs. The required
total IO must be calculated and specified at ordering.
Hardware modules are configured with the Hardware Configuration Tool in the
PCM600 engineering platform.
The Application Configuration tool, which is part of the PCM600 engineering
platform, will further to the four arrangements above include also alternatives for each
of them with all of the software options configured. These can then be used directly or
as assistance of how to configure the options. As the number of options can vary all
alternatives possible cannot be handled.
The configurations are as far as found necessary provided with application comments
to explain why the signals have been connected in the special way. This is of course for
the special application features created, not "standard" functionality.
The physical terminals for the configured binary inputs and outputs are found in the
connection diagrams for IEC 670 series 1MRK002801-AC.

Introduction
The RET 670 comes preconfigured for several applications.
ANSI RET670 Configurations
RET670-A30
RET670-b30
RET670-B40
Each of these configurations will be described below.
Description of configuration A30
This configuration is used in applications with two winding transformers with single or
double busbars but with a single breaker arrangement on both sides. The tripping is
three poles and also includes a synchronism check function for manual closing of the
low voltage side breaker. The high voltage breaker is foreseen to always energize the
transformer and be interlocked with an open LV side breaker.
