This new device is particularly for users who necessitate only a gradient control and do it without analyzing software. The gradient control gets along without PC and needs only little place.
Via the menu navigation programms can be easily and fast programmed. Once if the internal memory should not be sufficient or if the program data are needed for documentation these may be readout via a serial connection by a PC.
The unit possess 4 serial ports to communicate with new generation BESTA pumps. For older models or different makes 4 ports with analog voltage (0-10V) are available parallel. .
Via 7 I/O channels more, eg motor switch valves, can be triggered. Per channel
the break contact element and the normally open contact of the relay is leaded
through on the 25-pole Sub-D jack. A special channel is the impulse channel.
In the menu a impulse-aftermath will be entered, e.g. 5 min. Is the impulse
channel beeing activated within a programm it releases a impuls. This is particularly
meant for the glass change with fraction collection tanks.
