Function stirring
12.1
Intermittent mode
If Intermit mode is active, "On IntErmit" will be displayed when the
device is switched on.
The intermittent mode interrupts the stirring cycle at regular inter-
vals. For example, if the function
the setpoint speed set at 1 rpm the stirring cycle will be interrup-
ted for approx. 10 seconds after a cycle time of 60 seconds. The
cycle time and the length of the interruption can be modified via
the serial interface (see section 15.1).
The stirring bar breakaway monitoring function cannot be
enabled when the intermittent mode is enabled.
The intermittent mode can also be used with the special small stir-
ring bars. These can be used when the stirring bar breakaway
monitoring function is not enabled and will continue to stir the
medium even when the stirring bar breaks away. These stirring
bars are picked up once again when the speed drops cyclically.
