2-9 ERROR CODE INDICATION
The instrument has an error code indication to
define faster and better possible malfunctions.
The error codes E-01, E-02 and E-04 refer to
the function of the integrated feed mechanism
and to the condition of the battery buffer for
storing data and is shown on the left display.
The error code E-03 refers to the temperature
of the cooling chamber and is shown on the
right display.
2-9-1 DEFINITION OF THE
ERROR CODES
The error code E-01 is shown on the left
display and indicates that there is a
malfunction in the power amplifier of the
instrument.
The user now knows that the integrated feed
mechanism is not ready to operate.
In this case, a trained service
technician must
be
called.
The error code E-02 is also shown on the left
display and indicates that the battery for the
stored data is empty. This means that the
indication of the real time clock as well as of
the defrost timer is wrong. However, the
instrument can be operated.
After a few seconds the error code E-02
disappears automatically. The variable values
are then cleared. The set value of the
temperature is adjusted to a default value. To
select other values, press the UP or DOWN
buttons.
The battery should then be replaced by a
trained service technician as soon as possible.
The error code E-03 is shown on the right
display, if the temperature of the cooling
chamber is higher than 0° when turning on
the
instru
ment. This error code indicates that no
cooling process was carried out for a longer
time caused by power failure or turning off the
instrument. In these cases, the instrument
warms up and the cooling chamber as well as
the microtome with knife carrier of the
instrument gets wet or humid.
