Reinstall the option board.
Faulty Ethernet board.
Replace the board.
Temperature High Alarm
This error message is caused by the temperature signal from the conductivity sensor exceeding the
user-programmed value for the high alarm limit.
Possible
Causes

The temperature sensor has lost calibration.
Go to the Temperature Input Page and calibrate
the temperature.
Faulty circuit board.
Go to the Temperature Input Page and perform
a self test. If the self test fails, then the sensor
input board (if makeup) or the core interface
board (if system) should be replaced.
Faulty temperature sensor.
If a successful calibration is not possible,
the temperature sensor is probably faulty, and
the sensor should be replaced.
