CHAPTER 3 BASIC OPERATION
3-20
To activate the heater burnout alarm, set the HBA used" parameter
(advanced function settinglevel) to ON" and theheaterburnout set value
in the heater burnout detection" parameter (adjustment level).
In this example, set the heater burnout detection" parameter to 2.5".
• Moving to the advanced function setting level
The default of the heater burnout" parameter is already ON", so set the
heater burnout detection" parameter.
(1) Move to the advanced function setting level.
Press the key for at least three seconds to move from the operaĆ
tion level" to the initial setting level".
(2) Then move to advanced function setting level" by pressing the
key.
(3) Use the keys to input the password (-169"), and move from
the initial setting level" to the advanced function setting level".
The top parameter in the advanced function setting level" is disĆ
played.
(4) Select the HBA used" parameter by pressing the key.
Make sure that this parameter is set to ON" (default).
Next, set the heater current value monitor" parameter.
• Setting heater burnout detection
(5) Press the key for at least one second to move from the advanced
function setting level" to the initial setting level" and then to the
operation level".
(6) Press the key for less than one second to move from the operaĆ
