6.11 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 due
to 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.
NOTE – Response delay
To prevent short-time changes of the operating
conditions from resulting in repeated failure
messages during the operation of the incuba-
tor, 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
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
2
nominal value is reduced, a failure
message (code 101/201) may be set due to the
inertia of the atmosphere within the work spa-
ce. Therefore, the device doors should be ope-
ned for some time if the nominal values are
reduced.
