c) If there is an error, any of LED D800 to D804 goes
on. (Display 1)
d) When pushing the pushdown button switch SW800 for
approx. 1 second, the display is exchanged. (Display 2)
e) When pushing SW800 again or after 2 minutes, the
status returns to that of Display 1
1Ph and 12HT-15HT 3Ph) (Fig. 13)
The error which is generating at present and the latest
error (latest error information including present) can be
conrmed by lighting LED D800 toD804 on the outdoor
control P.C. board.
a) When all DIP switch SW803 are OFF, the status of
error which is generating at present is displayed.
b) <1> only of DIP switch SW803 is turned on, the error
which generated before (latest error information
including present) is displayed.
