VALVE:DOWN
Description:
This command closes the valve. It is the only instruction accepted in a
“VALVE:UP“ phase. In other situations it has no effect.
Example:
Input:
VALVE:DOWN
Result:
The valve closes.
Return:
OK
43
VALVE:OPEN
Description:
This command initiates a dispensing cycle with the parameter combination
currently selected.
Example:
Input:
VALVE:OPEN
Result:
The system launches a dispensing cycle, using the parameters
given by the working configuration or select pins, respectively.
Return:
OK
44
VALVE:OPEN:<Rising>,<Open Time>,<Falling>,<Needle Lift>,<Number of Pulses>, <Delay>
Description:
This command initiates a dispensing cycle with the parameter combination
currently selected. Time parameters have to be specified in 1/10 ms, except
for “Falling“, which has to be entered in 1/100 ms.
Specified values must be integer and positive. To choose the external mode,
enter “EXTERNAL” for “Open Time”, instead of a numerical value. You have
to include all six setup parameters.
Parameters previously entered by “TRIGGER:SET“ are not erased.
The values entered by “VALVE:OPEN:<Rising>,<Open
Time>,<Falling>,<Needle Lift>,<Number of Pulses>,<Delay>”, are valid only
until the end of the dispensing cycle. If the combination is intended to be
used several times, the complete command has to be repeated at the begin-
ning of each single cycle. In such a situation it would be more practical to use
the “TRIGGER:SET“ command instead, since the cycle in this case can be
reactivated simply by “VALVE:OPEN“.
Example:
Input:
VALVE:OPEN: 30,10,15,90,20,8
Result:
The dispensing cycle contains 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
45
VALVE:AOPEN
Description:
This command initiates a dispensing cycle with the parameter combination
currently selected.
Example:
Input:
VALVE:AOPEN
Result:
The system launches a dispensing cycle, using the parameters
given by the working configuration or select pins, respectively.
Return:
OK
