power fail resume feature
cannot be used
The EEPROM is worn out;
no storage space is
available for storage of
recipe execution information.
Therefore, this message is
displayed when power is
restored after a power failure
that occurred while a recipe
was being executed under
the direction of the
controller. When this
message is displayed,
execution of the recipe
cannot be resumed
automatically.
Press any key to clear the message.
Call for service. (See Note 1 below.)

interrupt-related problem
While one of these
messages is on display, the
controller outputs are held at
the relay state or analog
output percentage in use
when the problem was
detected.
Cycle the power to the controller. If the
message recurs and persists, call for service.
Note 1: A host computer can wear out the EEPROM by writing to it too many times. Do
not write the setpoint to the EEPROM when you are writing a temporary setpoint to the
controller, such as when you are ramping to a final setpoint under the direction of a
MODBUS master.
