① Press the SELECT switch 14 times. "E6" and "E7" are
shutdown histories of the DCBL controller. 5 of "E5." indi-
cates the oldest display of the digital monitor.
② Press the RESET button. The screen returns to the usual
digital monitor display.
IMPORTANT
1． If the shutdown code "XX" is "
no shutdown history. When other than shutdown
history displayed without performing shutdown
reset, it returns to the newest shutdown history dis-
play 3 minutes later.
2． The shutdown histories of the DCBL controller and
the fan inverter are recorded for the latest shutdown
only. The shutdown code displays a dedicated code.
( See shutdown code on this page.)
