50 STRIGGER:ASET:<RI>,<OT>,<FA>,<NL>,<NP>,<DL>,1
Description:
As described pulse parameters can be modified and saved in EEPROM in
the control unit (reaction time: 200 ms). (The latter marks the difference to
the command before this one. It is shown in the command line with the “1”
at the end.) It does not transmit a trigger command.
Both of the parameters “Falling” and “Rising” are specified in steps of
0.01 ms. Minimum value for “Falling”: 0.01 ms, for “Rising” 0.01 ms. But the
minimum values for Falling and Rising also always depend on the current
Needle Lift % (see paragraph 7.4, page 66).
All other time parameters are entered in units of 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.
The start of a dispensing cycle with the selected parameter configuration is
initiated by the command “VALVE:AOPEN”.
This command works just like its “TRIGGER” variant. Only the MDC does not
answer with “OK”, but with the saved parameters instead. This way the
machine software can check directly, if the parameters were received
correctly.
Example:
Input:
STRIGGER:ASET:55,10,8,80,20,8,1
Result:
The following values are assigned:
Rising: 55 ≙ 0.55 ms (ms = Millisecond)
Open Time: 10 ≙ 1.0 ms
Falling: 8 ≙ 0.08 ms
Needle Lift: 80 ≙ 80 %
Number of Pulses: 20
Delay: 8 ≙ 0.8 ms
Return:
55,10,8,80,20,8
51 VALVE:UP
Description:
The valve is opened until it receives the command “VALVE:DOWN” or 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
52 VALVE:DOWN
Description:
This command closes the valve. It is the only command accepted in a
“VALVE:UP” phase. In other situations, it has no effect.
Example:
Input:
VALVE:DOWN
Result:
The valve closes.
Return:
OK

53 VALVE:AOPEN
Description:
This command initiates a dispensing cycle with the parameter combination
currently selected. Usually this is the working configuration (setup 0). But if
in the menu SCENARIO is ON (see
paragraph 4.5.5, page 35), then the
parameters of scenario 1 are chosen. If the select pins are activated (see
paragraph 7.8, page 68), the setup (or scenario) is determined by them.
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
Result:
The system launches a dispensing cycle, using the
parameters given by the working configuration, scenario 1
or the select pins, respectively (for further information
about scenarios and the select pins, see
paragraph 7.9,
page 70). Usually this is the working configuration (setup 0).
But if in the menu SCENARIO is ON (see paragraph 4.5.5,
page 35
), then the parameters of scenario 1 are chosen. If
the select pins are activated, the setup (or scenario) is
determined by them.
Return:
OK

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
