Safety Systems and Error Codes
This incubator features safety systems independent of the controller, in addition to the self-diagnostics
function of the controller. The table below shows the causes when the safety systems go into effect
and the countermeasures to be taken.
If an abnormality such as an operational error or equipment failure occurs, the corresponding error code “ErrX”
(where X is a number) appears on the operation panel display and a buzzer sounds. In this case, check the
error code and immediately stop operation.
