Vacuum Controller
V-800/V-805
10 Control function in connection
with Rotavapor R-200/R-205
10.1 Start of rotation
The Vacuum Controller V-800/V-805 makes it possible to
automatically start rotation of the evaporating flask. This
function is activated and deactivated in the configuration menu.
The rotation speed corresponds to the respective rotary button
setting of the rotary evaporator. In spite of the activated
autostart function, you can also rotate the evaporating flask
at any time without start of controller. For this purpose, you
simply turn slightly on the respective regulating button of the
evaporator.
Configuration possibility: start rotation On/Off
10.2 Stop rotation
If the function is activated, when the controller stops, rotation
of the evaporating flask is automatically stopped. This function
is turned on and off in the configuration menu.
Configuration possibility: Stop rotation On/Off
10.3 Automatic lowering of the evaporating flask
When configured accordingly, when the controller starts, the
evaporating flask is automatically lowered into the bath. It is
essential that the lower end catch is correctly set in the quick-
action jack of the rotary evaporator. Hand operation of the
quick-action jack is already priority effective.
Configuration possibility: Lowering ON/OFF
10.4 Automatic raising of the evaporating flask
This function is also only active when configured accordingly.
When the controller stops, the evaporating flask is automatically
lifted from the heating bath to the upper end catch. Hand
operation of the quick-action jack is always priority active.
Configuration possibility: Lifting ON/OFF
