Configuration
7.4.6.1 Setting the Lift Parameters
When the sample lift is activated, the lift air valve is slowly opened from “start%” to
“stop%” in steps of “step”, pausing “time” x 32ms at each step. Typical default values
for an input pressure of 4 bar are shown in the example below. You can slow down the
lift by increasing the time per step or reducing the step size. In order to save these val-
ues to the non volatile memory of the board, press “save to NVRAM”.
The lift can be tested from the web pageside using the up/down toggle function
7.4.6.2 Setting the Spin Parameters
When the sample spin is activated, the spin air valve is slowly opened with “offset%”
and holds this value for a time given by the number of ticks (in the example below 3 x 30
x 32 ms = approx 3 seconds) before beginning the PI control. Typical default values for
an input pressure of 4 bar are shown in the example below.
The starting value of the air valve setting should be close to the value that the PI control-
ler finally settles down to. This vale can be read out under “Control PWM value (%)” and
should then be entered to “offset%”.
In order to save these values to the non volatile memory of the board, press “Apply
Changes”.
The spin can be tested from the web page using the start/stop toggle function.
