3.2.3 Error display
➢
When faults of the refrigerator temperature display sensor including short circuit, open circuit,
malfunction and incorrect
connection appear, “E0” is displayed. When faults of the refrigerator
temperature control sensor including short circuit, open circuit, malfunction and incorrect connection
appear, “E1” is displayed. At the same time, the buzzer of the temperature controller will give out alarm
and the display screen displays corresponding alarm parameters (E0
，
E1).
➢
After the power is switched off, the control function of the controller fails and the back-up source is used
for displaying. If the back-up source is charged for more than 10 hours, the power failure symbol
“
Pd
”
,
the current inside temperature and the alarm display alternatively for one time and then display again
after 30S stop for cycle operation. After 8 hours, the nixie tube stops displaying. The power failure alarm
light will 5S twinkle continuously until the electric quantity of the back-up source is used up. The inside
temperature can be continuously displayed during the power failure. Please pay attention to this and take
relevant measures to avoid damage.
➢
Suggest: If you judge that the temperature sensor goes wrong, you should cut off the power and first
check whether the connecting wire of the sensor is loose. Please contact professional after-sales service
or distributor of us for processing.
Tips: if internal code appears when user regulates the temperature controller, the user should
wait for 1 minute and then operate it till the inside temperature is displayed to avoid fault of the
medical refrigerator caused by the changing of the control parameter.
➢
When the medical refrigerator stops temporarily due to power failure or other faults, the inside
temperature of the medical refrigerator will rise from 5
℃
to 15
℃
within 1 hour. If power cannot be
supplied in short time, the user should consider taking out the stored goods and putting them into other
normal medical refrigerators for storing to avoid losses caused by the damage of the stored goods.
➢
Before putting goods into the medical refrigerator to be stored, the user should confirm in advance that
whether inside temperature of the medical refrigerator is in accordance with the set temperature for
storing to avoid losses caused by goods damage due to the improper temperature.
➢
Due to the refrigeration inertia, the medical refrigerator cannot be kept at constant temperature. And
there is certain up and down difference between the inside temperature and the set temperature. The
inside temperature varies with the changing of the environmental conditions and the temperature set . It
belongs to normal phenomenon.
