(Note1) Item codes 1 through 18 indicate error histories. Each history has the error code, error detail code, and time as a set.
(Note2) Error histories are displayed from the newest to the oldest. (Each history has the error code, error detail code, and time as a set.)
Up to the past six histories can be displayed. (The older ones will be deleted.)
(Note3) If the error history is empty, "----" will blink.
(Note4) Refer to section "2. Checking the sensor status" for details. (page 115)
(Note5) When the input type is selected
When the input type is not selected = 0
