Heater-Cooler System 3T • Operation
CP_IFU_16-XX-XX_USA_015 5.15
5.5.2 Error displays
Most error messages indicating “Error Codes” simultaneously trigger alarms which always lead to a
total standstill of the respective functional group. For example: An error in the temperature control of
the cardioplegia circuit stops this circuit; the patient circuits, however, are not affected. Errors
affecting the entire heater-cooler, lead to a total standstill of all circuits.
Error displays on the heater-cooler (base unit)
You can try to clear the “Error Codes” by means of a “Cold start” (switch the unit off for about 10
seconds and restart).
◗ If the error code remains, there is in any case a defect and the device should not be used.
◗ If the error code is cleared, the heater-cooler should be checked by the designated service
technician at the earliest opportunity.
◗ Display
➜ Possible causes
◗ Effects
➜ Corrective measures
◗ Two or three dashes on one of the
actual temperature 7-segment displays
➜ Illogical values below 0°C or above
50°C indicate a defective temperature
sensor
◗ Incorrect or no actual temperature
measurement
➜ The circuit in question cannot be used.
Pass the device on to your service
technician as soon as possible.
◗ “EE(E)” flashes on one or several
7-segment displays, alternatingly with
an error code:
◗ Dependent on the kind of error (error
code number), the error has an impact
upon the function of
–a single circuit or
– the entire heater-cooler
During priming
➜ Error Code 08, 19, 23: ◗ The error messages disappear as soon
as the system is completely primed.
See page 5.11
During operation
➜ Error Code 0... 59:
Error in the heater-cooler base unit
◗ The heater-cooler cannot be, or only
partly be used.
◗ If this error only has an impact upon
one circuit, the remaining circuit can be
used. Only the affected circuit is non-
operational.
➜ Notify the designated service
technician.
