5.2 Performance during and after power failures
During a power failure, all controller functions are shut down.
After the power returns, all functions return to the same status the chamber had before power failure. The
set-points are immediately resumed.
If during power failure an alarm has occurred (tolerance range, safety controller etc.), confirm the alarm.
See chap. 13.
6. Start up
After connecting the power supply and filling the freshwater can, turn on the chamber by its main power
switch (1). The lit pilot lamp shows the chamber is ready for operation.
The controller shows normal display and controls temperature and humidity to the last entered values.
For operation with humidity, the humidifying and dehumidifying system must be activated (chap. 8).
For operation with humidity:
•
Activate the humidifying and dehumidifying system (chap. 8).
•
Open the freshwater can tap (chap. 4.1.3)
•
Do not firmly close the lid of the freshwater can to allow air to enter the freshwater can. As a result,
obstruction of the water supply due to negative pressure inside the can is avoided.
After the first turning on of the chamber or after an interruption of the power supply the relative humidity
will increase after a delay of about 20 minutes. During this period, the relative humidity can drop consid-
erably.
Warming chambers may release odors in the first few days after commissioning. This is not a quality
defect. To reduce odors quickly we recommend heating up the chamber to its nominal temperature for
one day and in a well-ventilated location.
WARNING: If customer should use a BINDER chamber running in non-supervised continu-
ous operation, we strongly recommend in case of inclusion of irrecoverable specimen or
samples to split such specimen or samples and store them in at least two chambers, if this is
feasible.
