Things To Do Before Loading New Firmware/Software

Ensure that a secure copy of relay settings is available as all settings will be lost during the code upload process.
A hard copy is useful for checking purposes. It is usually possible to download the existing settings into Reydisp
Evolution, save the file and then reload these settings into the relay following the upgrade. Reydisp will highlight
any changes that it cannot automatically resolve for you to manually correct when re-installing the settings..
If the relay is in service then it is advisable to remove any TRIP LINKS to prevent in-advertent mal-operation due
to incorrect settings being applied.
The attachments are password protected self extracting zip files to prevent email systems discarding them or
modifying them which should be saved with the "EX" extension renamed to be "EXE". The password that is
applied to this zip file is "REYROLLE" in capital letters.

Loading code using front usb port

New firmware/software may be loaded via the USB port on the front Fascia.
Check compatibility of software before starting the procedure. The relay will not accept firmware/software for
which the MLFB ordering code is not supported.
Installation instructions are provided with the upgrade firmware and should be studied before the procedure is
attempted..
A USB connection between a PC and the relay front port is required.
The process may take several minutes to complete at which time the relay will restart.
Please make note of any warning or error messages that appear on the Reyfresh terminal window as the relay
restarts.
