Help messages and recommended actions
Checksum error was detected in the nonvolatile memory
configuration data when the unit was turned on. Default
values have been loaded. Check to see that your
configurations have not been changed. Cycle the power to
clear alarm.
Communication failure detected between the sensor board
and the main board, indicating the sensor board has been
disconnected from the main board.Check the connecting
cable pins.
The sensor type does not match, indicating wrong sensor
board is connected.
The sensor board software version does not match the
expected version, indicating the sensor board software
needs to be upgraded. Place the jumper on J1 of the
sensor board and cycle the power to start the sensor board
software upgrade.
The Bootload Mode jumper at J1 of the sensor board is on
at power up. This mode should only be used to upgrade the
sensor board software. Remove the jumper from J1 of the
sensor board and cycle the power to clear the alarm.
Help messages and recommended actions
The sensor heater thermocouple voltage is reading
a negative voltage, indicating the thermocouple wire
connections may be reversed. Check wiring.
