Flash messages are warning, error, or general information messages displayed in response to certain key presses. The
length of time these messages remain displayed can be programmed in
. The factory default flash message time is 4 seconds.

SEVERITY
CAUSE
major
This error is caused by detection of corrupted location in the 745 data memory which cannot be
self-corrected. Errors that can be automatically corrected are not indicated. Any function of the
745 is susceptible to maloperate from this failure.
major
This error is caused when an error in FlexLogic™ is detected. No feature of the 745 that is
controlled by FlexLogic will operate when this failure occurs. Programming correct FlexLogic
equations will remove this error.
major
This error is caused when communications with the internal digital signal processor is lost.
Most of the monitoring capability of the 745 (including all measurement of current) will be lost
when this failure occurs.
major
This error is caused when the 745 determines that the transformer configuration programmed
via setpoints does not correspond to a realistic physical system.
minor
This error is caused by failure of the +32 V DC power supply used to power dry contacts of
logic inputs. Logic inputs using internal power are affected by this failure. This may be caused
by an external connection which shorts this power supply to ground.
minor
This error is caused by failure of the +32 V DC power supply used to power analog outputs.
Analog output currents are affected by this failure.
minor
This error message appears when the 745 determines that it has not been calibrated. Although
the relay is fully functional, the accuracy of measured input values (e.g. currents and line
voltage) as well as generated outputs (e.g. analog outputs) is not likely to be within those
specified for the relay.
minor
This error is caused when the 745 detects that the real-time clock is not running. Under this
condition, the 745 will not be able to maintain the current time and date. This would normally
occur if backup battery power for the clock is lost and control power is removed from the 745.
Even if control power is restored, the clock will not operate until the time and/or date are
programmed via the
minor
This error is caused by development software being loaded in the relay.
minor
This error is caused by the detection of unacceptably low (less than –40°C) or high (greater
than +85°C) temperatures detected inside the unit
minor
This error is caused when the IRIG-B signal type selected does not match the format code
being injected into the IRIG-B terminals.
minor
This error is caused when the passcode is entered incorrectly three times in a row from either
the front panel or any of the communication ports. This error may be removed by entering the
correct passcode.
minor
This error is caused when ambient temperature is out of range.(–50 to 250°C inclusive).
This flash message is displayed in response to pressing
message with a numerical value. The edited value had to be adjusted to the nearest
multiple of the step value before it was stored.
This flash message is displayed in response to executing a command at a command
message. Entering Yes at a command message will display the message
