Switchos Ii Controlled By Event Outputs - LC Packings SWITCHOS II User Manual

Software Control
4.2.3
If serial control is not possible (e.g. no free COM port available), the Switchos
loading pump can be used to control the valve positions. The switching valves
are then controlled by the event outputs of the Switchos II loading pump
(TABLE 4-1) and EVENT8 can be used to trigger another device (e.g. a mass
spectrometer).

Note: The EVENT number as well as the type are indicated on the rear panel of
the Micropump (e.g. EVENT 1 'TTL', EVENT 3 'OC', etc.). Make certain that the
proper EVENT output is linked to the corresponding signal name of
CHROMELEON (e.g. 'Valve_A' should control EVENT3 of the Micropump, 'SSV'
should control EVENT7, etc.).
To control the unit by the event outputs of the Loading Pump:
a) Select the Relays tab of the LC Packings UltiMate/Switchos box (FIGURE 4-4).
FIGURE 4-4
b) Check the outputs 'SSV', 'Valve_A', and 'Valve_B', check 'Switchos_Relay_2'
if you want to trigger any instrument by the EVENT 8 output.
Note: The default signal names corresponds to the names used in the
(predefined) panels and should not be changed. If you modify the signal names,
they may not be recognized and some functions may not work properly.
