Reading failure codes
The device is equipped with a failure diagnostic system. This system recogni-
zes failures during the operation and allows the allocation of failure causes by
numeric codes. Failure recognition is displayed by an acoustic and a visual alarm
at the operating panel. The diagnostic system stores the last 10 failures in the
sequence of their occurence. The failure table can be requested and read.
If the cause of a failure cannot be repaired, please have the fault code and the
serial number of the device available when contacting Technical Service.

Incubator BB 150 Operating Instructions

NOTE – Response delay
To prevent short term changes of the opera-
ting conditions from resulting in repeated fai-
lure messages during the operation of the
incubator, the diagnostic system has a re-
sponse delay:
•
After changes to nominal values:
max. 152 min
•
After the glass door has been opened:
max. 45 min
•
Other failure causes: max. 1 min
NOTE – Delay time reset
If the set nominal value is reached during the
specified period, the delay time is reset to 1 min.
NOTE – Failure cause
When the temperature nominal value and/or
the CO
nominal value is reduced, a failure
2
message (code 101/201) may appear due to the
slow reaction time of the atmosphere within the
work space. Therefore, the device doors
should be opened for some time if the nomi-
nal values are reduced.
