Example:
Input: VALVE:OPEN: 30,10,15,90,20,8
Result: The initiated cycle comprises the following values:
Rising: 30
≙
3,0 ms (ms = Milliseconds)
Open Time: 10
≙
1,0 ms
Falling: 15
≙
0,15 ms
Needle Lift: 90 %
Number of Pulses: 20
Delay: 8
≙
0,8 ms
Return: OK
24. VALVE:AOPEN:<Rising>,<Open Time>,<Falling>,<Needle Lift>,<Number of Pulses>,<Delay>
Description: This command corresponds to instruction no. 23 described above. In this
case however, both of the parameters “Rising“ and “Falling“ are specified
in steps of 1/100 ms, in contrast to the other ramp parameters (1/10 ms) .
Specified values must be integer and positive. If the External Mode is de ‐
sired, instead of a numerical value enter “EXTERNAL” for “Open Time”.
Also in this case, parameters previously entered by “TRIGGER:SET“ are not
erased, but the combination remains in the system only until the end of
the cycle. Therefore, if the user does not wish to reenter the entire com ‐
mand several times, the “TRIGGER:SET“ command is advantageous, since
here the cycle can be reactivated simply by “VALVE:OPEN“, as desired.
Example:
Input: VALVE:AOPEN:30,55,8,80,20,8
Result: The dispensing cycle includes the following values:
Rising: 30
≙
0,3 ms (ms = Milliseconds)
Open Time: 55
≙
5,5 ms
Falling: 8
≙
0,08 ms
Needle Lift: 80 %
Number of Pulses: 20
Delay: 8
≙
0,8 ms
Return: OK
25. VALVE:UP
Description: The valve is opened until it receives the command “VALVE:DOWN”. Other ‐
wise it closes automatically after 2 min. During this phase, other commands
are ignored, in order to protect the valve.
Example:
Input: VALVE:UP
Result: The valve opens.
Return: OK
26. VALVE:DOWN
Description: This command, closing the valve, represents the only instruction accepted
in a “VALVE:UP“ phase. In other situations, it remains without effect.
Example:
Input: VALVE:DOWN
Result: The valve is closed.
Return: OK
