CTU in operation
Automatic reservoir switchover
The levels in reservoirs B1 and B2 are continuously monitored during the
rinsing of the inner chamber.
When the level in reservoir B1 reaches the lower threshold, the system
automatically changes between reservoir B1 and reservoir B2 so that when
processing continues, the test liquid will be pumped from reservoir B2 to B1.
The message "Switching reservoirs - Please wait"
is output in the status line of the ConTeS.
The status light additionally blinks red .
The supply of test liquid will be stopped. It takes about 30 seconds to change
over the rinsing reservoirs.
If rinsing of the inner chamber is complete before the remaining volume has
been used, the system will immediately switch containers as soon as the
rinsing stops.
If both reservoirs B1 and B2 reach the lower threshold at the
same time, the CTU will constantly switch from one to the other.
This is possible if the test/analysis liquid is still in the analysis
chamber or is in another, external test item.
• Check that the ball valve is in the "Open" position.
• Check the filter membrane, as it is possible that this is so
blocked that no more analysis liquid can be sucked away.
• Use the vacuum to suck the test/analysis liquid back into the
reservoirs. You can use the "Fill CTU" function in the
software.
