The indication list of alarm code.
The Eco Rich equipped with alarm detective function which classified as follows.
◆
Alarm code and abnormal phenomenon
Classification
①
Indicating alarm, at the same time, outputting alarm signal, then stopping operation forcibly.
Classification
②
Following actions are led by setting of setup mode item P02 (temperature alarm output setup) .
・
Setup value
『
0
』
: Not detect an alarm.
・
Setup value
『
1
』
: Indicating alarm and outputting alarm signal, then stopping operation forcibly 10 minutes
later. [Standard model : at sipping condition]
Classification
③
Following actions are led by setting of setup mode item P04 (pressure switch working pressure) .
(This alarm is pressure switch function.)
・
Setup value
『
0
』
: Not detect an alarm. [Standard model : at sipping condition]
・
Except setup value
『
0
』
: When the pressure decrease of setup time P03 (Delay time setup of pressure alarm)
continue, an alarm signal is outputting. It is canceled if the pressure reverts to the
normality. Operation is continued.
Classification
④
It is shown that there was “retrial action” to avoid operation stop in order not to stop the unit forcibly.
(Alarm code isn’t indicated.)
When it can’t be avoided, it is stopped forcibly, and alarm code
①
is indicated.
Classification
⑤
It is recorded only as an internal information.
Neither the stop of the unit nor the output of alarm signal.
Classification
⑥
Only when the item P04 (setup of pressure switch operation pressure) of the setup mode is effective,
and PO9 (setup of pressure switch operation indication holding) is “1”, alarm code is indicated.
However, alarm indication is held.
