Note 1: The display and output may be uncertain depending on the nature of the ROM error.
Note 2: If a parameter failure relating to the current output occurs, the current output may not become exactly
the set value of the current output used when an alarm occurs.
Note 3: The output becomes the value selected in 8.2.11 “Current Output Setting Used When an Alarm
Occurs.”
Note 4: If the fluid empty alarm not included (WITHOUT EMP) is selected (standard) in the setting for alarm
output factors in 8.2.19 “Self-Diagnosis Function,” the output becomes 4mA and if the fluid alarm
included (WITH EMP) is selected, the output becomes the same as the above in Note 3.
