transmit frequency.

through J22 on the 9508 Line Board can be strapped in varying combinations to improve
loss if desired.

4.6.4 CURRENT DIFFERENTIAL RELAY COMMISSIONING PROCEDURE
Please review the following important information on the GARD Current Differential Relay
Module before beginning the commissioning procedure.
If the Current Differential Relay module was purchased as part of the GARD8000 system, the
Current Diff. Relay Protection Scheme logic consisting of edn, text files and Current Diff.
Relay settings were already loaded into the GARD8000 system. However, if the Current Diff.
Relay module was added into an existing GARD8000 system, new Current Diff. Logic and
settings have to be uploaded into the GARD8000. All the necessary steps on how to upload a
new Current Diff Relay logic are covered at the end of this Commissioning Procedure (sections
4.6.4.17 and 4.6.4.18).
A hard copy and/or a CD of the GARD System Instruction Manual is provided with the
purchased system. The software version of the GARD Instruction Manual can be downloaded
from the RFL website: (http://www.rflelect.com/operatingmanual.html) or from the
GARD8000 System chassis. Note that because of file size restrictions the manual downloaded
from the GARD chassis has all graphics removed. (Once the GARD is powered up; from the
Home web page click on “Settings,” select “File Operations,” select “Save File to PC," select
“Gard System Manual PDF.”
The GARD 8000 Emulator software can be used ahead of an actual commissioning in an off-
line mode in order to program the Current Diff Relay or GARD8000 system settings and save
them to a file. Later, during the commissioning this file can be uploaded to the GARD 8000
system. The GARD 8000 Emulator software can be downloaded from RFL website:
