Error code indication
e instrument has an error code indication to define faster and better
possible malfunctions.
e error codes describe so-called system errors. Additionally, error mes-
sages are shown on the display as text messages, e.g. when the temperature
sensors are faulty, when the end position of the specimen clamping has
not been reached, when there is a high pressure in the cooling system and
when the function of the automatic approach system is faulty (see page 43).
Note:
If an error code appears on the display of your instrument, please note it
down and contact your sales organization where you bought the instrument
or directly contact ermo Scientific Microm International GmbH.
Four different error codes, which indicate a defect on a temperature
sensor, can appear on the display. e message is shown on the second
line from below on the display (fig. 126):
e instrument recognizes a faulty operation on the specimen tempera-
ture sensor, which is placed in the specimen head.
e instrument recognizes a faulty operation on the box sensor, which is
placed on the base plate of the microtome.
e instrument recognizes a faulty operation of the defrost limiting
sensor, which is placed between the fins of the evaporator.
e instrument recognizes a faulty operation of the defrosting limiting
sensor, which is placed between the fins of the evaporator.
Note:
However, you can work with the instrument to a certain extent until the
operational fault is removed by a trained service technician.
