54 VALVE:AOPEN:<RI>,<OT>,<FA>,<NL>,<NP>,<DL>
Description:
With this command, both of the parameters “Rising” and “Falling” are
specified in steps of 1/100 ms, in contrast to the other time parameters
(1/10 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:ASET” are not erased, but the
combination remains in the system only until the end of the cycle. If you do
not wish to reenter the entire command several times, the “TRIGGER:ASET”
command is advantageous. This way the cycle can be reactivated simply by
“VALVE:AOPEN”.
Important Note!
In case you trigger a dispensing process in the Infinite Mode with this
command, you cannot stop it via the RS232C interface. You can only stop it
via the PLC interface or by pressing the [esc]-key on the MDC.
Example:
Input:
VALVE:AOPEN: 30,10,15,80,20,15
Result:
The dispensing cycle contains the following values:
Rising: 30 ≙ 0.3 ms (ms = Millisecond)
Open Time: 10 ≙ 1.0 ms
Falling: 15 ≙ 0.15 ms
Needle Lift: 80 %
Number of Pulses: 20
Delay: 15 ≙ 1.5 ms
Return:
OK
55 VALVE:AOPENS<setup no.>
Description:
This command initiates a dispensing cycle with the parameter combination
of the setup (or scenario) indicated in the command.
You decide to dispense with the parameters of a specified setup (or
scenario, if SCENARIO is “ON”), by using one of the following command
extensions:
• S0 - uses parameters of setup 0 (or scenario 1 with SCENARIO “ON”)
• S1 - uses parameters of setup 1 (or scenario 2 with SCENARIO “ON”)
• S2 - uses parameters of setup 2 (or scenario 3 with SCENARIO “ON”)
• S3 - uses parameters of setup 3 (or scenario 4 with SCENARIO “ON”)
These parameters are used even with activated select pins. As an example,
to dispense with the parameters of setup 2 you have to enter the following
command:
VALVE:AOPENS2
For this example, SCENARIO has to be “OFF” in the menu.
Important Note!
In case you trigger a dispensing process in the Infinite Mode with this
command, you cannot stop it via the RS232C interface. You can only stop it
via the PLC interface or by pressing the [esc]-key on the MDC.
Example:
Input:
VALVE:AOPENS2
Result:
The system launches a dispensing cycle, using the
parameters given by the selected setup (or scenario; for
further information about scenarios and the select pins, see
paragraph 7.9, page 70).
Return:
OK
