Operating instructions
Error code indication
Before turning on the instrument on the main switch, it carries out an
automatic travel calibration of the specimen clamping. e specimen
clamping is brought into that position which has the longest distance to
the knife carrier.
If there is an operational fault during this process, e.g. debris or frost
impedes the specimen clamping movement, this is shown via the
message ‚NO END POSITION‘ and means that a calibration was not
carried out.
A service technician must be called.
e instrument is designed to check for internal system errors.
In case such an error is recognized, it is shown as
‚ER-10‘
to
‚ER-16‘
for approx. 5 sec. in the middle of the display.
e recognition of such an error leads to an automatic RESET-process.
e cause for this might be a temporary fault.
Note:
In case one of these messages occur more than once, please note down the
error code and contact a service technician.
ere is insufficient disinfection medium in the container. Please check
and refill disinfection medium if necessary. Restart the Cold D. It might
be possible that a repeatedly restart is necessary after filling the contai-
ner especially for the first time.
e Cold D cycle can only be carried out if the heated window is com-
pletely closed. Please check whether the heated window is closed and
restart the Cold D cycle.
e heated window needs to remain closed during the whole Cold D
cycle. If the heated window is opened during the process, this error code
appears. Close the window and continue.
A 2-hour wait period is required between the beginning of a subsequent
defrost cycle and a Cold D cycle. If this wait period is not complete
during the programming of the Cold D time, an error message appears
and the Cold D time is set at the next possible time.
