• Additionally, a mechanical/visual indicator for the maximum water level is available to assist the
user in filling the water reservoir
The sensor for the acquisition of the workspace temperature as well as the CO
O sensor are integral to the control system of the device. Their measured values are compared to the
2
selected set values. Based on this data, the control system controls heating and CO
The fan ensures that the incoming gases are well intermixed with the humidified air, thus providing for
an even temperature distribution throughout the workspace.
The overtemperature protection feature is factory-preprogrammed and requires specially trained service
personnel in case changes are needed. It protects the stored cultures from overheating.
If the set temperature is exceeded by more than 1°C, the thermal protection responds and the
workspace temperature is automatically reduced to the selected set value so that the incubation process
can be continued even in case of a failure. Any response of the thermal protection will simultaneously
trigger a visual alarm. If the thermal protection is enabled:
• An error message (Temp.-Actual value high) and an acoustic alarm signal are issued,
• the alarm relay responds.
If the error message is accepted, the display shows the Overtemperature icon to indicate the response of
the thermal protection, and the temperature display is highlighted in red.
