Downloading the configuration and setting files

When downloading a configuration to the REx670 IED with the CAP531 configuration tool, the
IED is automatically set in configuration mode. When the IED is set in configuration mode, all
functions are blocked. The red LED on the IED flashes, and the green LED is lit while the IED
is in the configuration mode.

When the configuration is downloaded and completed, the IED is automatically set into normal
mode. For further instructions please refer to the users manuals for PCM600.
