Ready Mode
Ready Mode is a standby mode for the E300 relay in which the relay is ready to
help protect an electric motor and no electrical current has been detected. You
can modify configuration parameters, update firmware, and issue commands if
the appropriate security policies are enabled. The Power LED on the
Communication Module and Operator Stations flash green and bit 14 in Device
Status 0 (Parameter 20) is set to 1 when the device is in Ready Mode.

Run Mode
Run Mode is an active mode for the E300 relay in which the relay is sensing
electrical current and is actively protecting an electric motor. Only non-motor
protection configuration parameters can be modified if the appropriate security
policies are enabled. The Power LED on the Communication Module and
Operator Stations is solid green and bits 3, 4, and/or 5 in Device Status 0
(Parameter 20) are set to 1 when the device is in Run Mode.
