• Performance after power failure during Week program operation
The week program continues with the values corresponding to the current time.
Power failure and power return are noted in the Event list (chap. 14).
If during power failure an alarm has occurred (e.g., tolerance range, safety controller), confirm the alarm.
See chap. 16.3.
8.3.2 RD4 controller
After the power returns, the set-points are immediately resumed.
If during power failure an alarm has occurred (e.g., tolerance range, safety controller), confirm the alarm.
See chap. 16.3.
9. Start up and performing the drying process
With regard to operating the vacuum drying oven VDL and to the installation location, please observe the
relevant national regulations (for Germany in particular: DGUV guidelines 213-850 on safe working in
laboratories, issued by the employers’ liability insurance association; Industrial Safety Regulation (Be-
trSichV); Ordinance on Hazardous Substances (GefStoffV); Technical Regulations on Industrial Safety
and Health (TRBS 1201 Part 1).
Note: Warming chambers may release odors in the first few days after commissioning. This is not a quali-
ty defect. To reduce odors quickly we recommend heating up the chamber to its nominal temperature for
one day and in a well-ventilated location.
Do not start up the chamber without technical ventilation (chap. 5.2.2).
9.1 Requirements for safe commissioning
Prior to turning on the chamber, the following points must certainly be met:
• Installation of the chamber (chap. 6) performed in compliance with the installation guidelines and am-
bient conditions (chap. 5)
• Connection for compressed air or inert gas for sweeping the electrical installation area and controller
housing
• Vacuum supply connected (chap. 6.4)
• If required: Inert gas connection established (chap. 6.5)
• Equipotential bonding established(chap. 6.6)
• Observing all safety instructions
• Upon initial commissioning: Test before initial commissioning performed and passed (Chap. 7.4)
• Upon recommissioning after maintenance / repairs / changes requiring review: Test performed and
passed (Chap. 7.5)
• Technical ventilation activated
• Power connection established (chap. 6.7).
