SYSTEM CONFIGURATION OVERVIEW
The GARD 8000 System differs from most conventional multifunctional distance relays in that rather
than supplied with very complex generic default logic, The GARD 8000 is intended to be easily
customized to meet your specific application requirements.
For most applications, the factory default logic may be suitable but RFL will modify it free-of-charge
as required.
The advantage with custom logic is that the user interface is greatly simplified as the web pages for
logic settings are automatically created to correspond to the actual logic.
While the logic is custom made, a considerable amount of settings and field flexibility can be built-in
to cover a large number of application needs. For instance, mapping of inputs and outputs, inverters for
inputs and outputs, timers, communications channel selections, etc. can all be made on web pages as
settings.
The distance relay in itself is highly programmable but the interaction in the system has been kept to a
minimum in order to simplify the system user interface. Recognizing the need for different
functionality for different users and/or applications, the logic signals (in and out) exchanged between
the system logic and the distance protection module can be custom specific.

HARDWARE CONFIGURATION
A GARD 8000 System can be built up with Functional Modules as required for a specific application,
with a selectable number of inputs, outputs and communications interfaces. Each GARD 8000 is
delivered with chassis drawings, showing the actual hardware and the factory default configuration.
These drawings are delivered as a paper copy and also in pdf format inside the GARD itself for print-
out or viewing on your PC.
The following overview describes a factory default configuration of a 3U chassis built up of:
•
Single Power Supply
•
Single Main Controller
•
Display Board with base Teleprotection System
•
RS 449 communications port on the rear of the PS module (included in Base System)
•
C37.94 communications module in rear Slot 1
•
Distance Protection module in front and rear Slot 3
•
12 input module in rear Slot 2
•
12 output module (6 solid state and 6 relay out) in rear Slot 4
