Fig. 8: ‘Service‘-monitor: Self-test failed
Note
In some cases it is helpful to switch off the unit and to switch it on
again after approx. one hour.
If a ‘Test failed’-symbol is shown again after that, please contact the
M&C Service!
7.4 Self-monitoring during operation
Note During its regular operation the unit runs automatic self-tests.
7.4.1 Power consumption readjustment
Over time the signs of aging of the Peltier elements increase gradually the value of the
internal resistance. As a consequence the power necessary to keep the target temperature
constant can not be supplied anymore. The projected capacity reserve compensates this
unavoidable aging effect and maximizes the service life of the EC-30C.
7.4.2 Pre-warning messages
If the capacity reserve has been exhausted up to a critical value, the unit will show a warn-
ing message about the upcoming failure. An exact definition of the remaining time, until
the breakdown of the unit, is not possible.
Note
Please plan servicing the unit ahead of time. The remaining service
life of the unit after the failure warning can not be determined
exactly.
If the reserve capacity is exhausted, an alarm message will occur. The unit still keeps on
cooling, but the target temperature will not be reached any more. The longer the unit will
be kept in this modus, the less it will be able to cool. The possible cooling temperature will
constantly rise.
