6.5 Turning on / off the interior socket voltage (with optional interior socket)
For chambers equipped with the optional interior socket (chap. 15.4) you can turn on and off the voltage
of the interior socket.
To turn on or off the interior socket voltage, go to Menu > Interior socket (optional)

Submenu “Interior socket”.
The current setting is displayed.
To change the setting, press the operating button
“Interior socket: On” = socket with activated voltage
“Interior socket: Off” = socket voltage-free
Close Home
Go back to the initial view with “Home”.
This symbol on the controller display indicates that the interior socket is activated.
6.6 Performance during and after power failure
During a power failure, all controller functions are shut down. The gas inlet valves are closed so that no
gas can escape into the ambient air. The zero-voltage relay alarm output (9) (chap. 11.6) is switched to
alarm position for the whole duration of the power failure.
After the power returns, all functions return to the same status the chamber had before power failure. The
controller continues to function in the original operating mode it was in previously before the power failure
occurred. In “fixed value” mode, the setpoints are immediately resumed.
If the chamber had been running in sterilization mode, the sterilization process is cancelled and the
chamber operates in “fixed value” operation mode with the setpoints already entered. All setpoint values
remain in memory.
If the temperature or concentration of CO
2
, and O
2
(chamber with O
2
control) have dropped below the
alarm limits during power failure, confirm the alarms with the RESET button as soon as the correct values
are reached again (chap. 11.4).
Power failure, including chamber shut-down with the main power switch, is listed in the event list.
After the power returns or chamber startup, this symbol and the message window “Power
supply was interrupted.” appear in the controller display. Confirm with OK to close the window
and make the icon disappear.
