温度制限を越えた原因で、プロテクションが働い
たことを示します。異常状態のままパワーオンす
ると、約1秒後にプロテクションが掛かり、電源
が切れます。
The protection function worked due to the
temperature limit being exceeded. Causes
could be poor ventilation or a defect related
to the thermal sensor. If the power is turned
on with the abnormality unsolved, the pro-
tection function works in about 1 second to
turn off the power.
各プロクテクションの検出に関しては、後述のダイアグメニュー
No. 10 AD DATAを参照してください。
History of protection function
When the protection function has worked, its history is
stored in memory with a backup. Even if no abnormality
is noted while servicing the unit, an abnormality which
has occurred previously can be defined as long as the
backup data has been stored.
The history of the protection function is cleared when
DIAG is cancelled by selecting PRESET RESERVED
(Memory initialized) of DIAG menu No.9 or when the
backup data is erased.
プロテクションの履歴
プロテクションが働いた場合、履歴をバックアップして記憶し
ています。サービスのときに異常が認められなくても、バック
アップが残っていれば、お客様のところで起きた異常を区別で
きます。
ダイアグメニュー No.9 で PRESET RESERVED（メモリー
の初期化）を選んでダイアグを解除した場合、またはバック
