6.3.2 Incubation temperature
The microprocessor-controlled PID-type regulation permits quick availability of the set temperature, at the same provid-
ing a high temporal temperature constancy of +/- 0.2 K. Display as well as setting the temperature is done digitally on an
LED display, in 0.1 K increments. The operating temperature is approx. 8 K above ambient temperature to 70 °C. The
serial cooling coil for connection to the domestic water supply or to a refrigerated circulator permits operation at set tem-
peratures as of 20 °C.
After switching the unit on, display 8 flashes and shows the last memorized set temperature, pilot lamp 11 glows. Use keys
12 (+) and 13 (-) to enter a new set temperature. Press key 25 to confirm the set temperature. The temperature con-
troller starts operation. Approx. 30 seconds after the last entry pilot lamp 11 goes out and pilot lamp 9 glows. The display
now switches from set temperature to actual temperature.
Three different temperatures can be selected and changed by pressing key 12:
1. Set temperature, pilot lamp 11 glows.
2. Difference point for over-temperature alarm, dependent on the set temperature (set temperature plus differ-
ence point = alarm point), pilot lamp 10 glows. Factory aligned at 04.0 = 4.0 K.
3. Difference point for under-temperature alarm, dependent on the set temperature (set temperature minus dif-
ference point = alarm point), pilot lamp 23 glows. Factory aligned at 09.0 = 9.0 K.
When key 24 is pressed, the displayed set point starts to flash and can be reset through keys 12 (+) and 13 (-). Press key
25 to confirm the new set point. Over-temperature and under-temperature alarms are signalled acoustically as well as
visually by error codes in the display. For further information on this subject, please see chapter 7.1 Error Codes of these
instructions. When opening the Incubator's cover, both heating and shaking drive will be switched off. After closing the
cover, the Incubator will restart with the set values of temperature and shaking frequency.
Caution,
the temperature in the Incubator's interior may rise up to 70 °C during operation. Danger of burns. Wea-
ring suitable safety gloves is recommended.
6.3.3 Shaking frequency
An overload-protected a. c. motor produces an orbital shaking motion with a shaking amplitude of 30 mm through the
robust, durable drive mechanism. The motor is controlled through a PID type microprocessor frequency regulation. The
shaking frequency can be set between 20 min
-1 to 250 min -1 , independent of the load. It is equipped with a gentle start-
up and can be set in increments of 1 min
-1
.
Press key 26 to switch the shaking movement on and off. After switching on the shaking device, the Incubator starts shak-
ing with the last set shaking frequency. Pilot lamp 15 glows, display 14 shows the actual shaking frequency. In order to
reset the shaking frequency, first press key 17 and then 27. Pilot lamp 16 glows, the display flashes and shows the set
shaking frequency. Use keys 17 (+) and 18 (-) to reset the displayed value. Press key 28 to confirm the new set value.
Even when the shaking device is switched off, the set shaking frequency can be read by pressing key 17 (pilot lamp 16
glows = set frequency). It can be reset as described above. Approx. 30 seconds after the last entry the Incubator auto-
matically switches back to operation mode (shaking device on or off). To switch off the shaking device, press key 26. The
shaking frequency is cut off slowly, the operation panel is switched off.
