7.7 Reading failure codes
Failure diagnostic system
The device is equipped with a failure diagnostic system. This system
recognizes 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 Ser-
vice.
NOTE!
Response delay:
To prevent short term changes of the operating conditions
from resulting in repeated failure messages during the opera-
tion of the incubator, the diagnostic system has a response
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!
