Description:
This command is used to modify pulse parameters without transmitting
the trigger signal. The values for both of the parameters “Falling” and
“Rising” are specified in steps of 0.01 ms. Minimum value for “Falling” is
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.
You have to include all six setup parameters.
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.
Information:
With this command, the information is only held in the RAM and therefore
gets lost, once the system is switched OFF. If that is a problem, use the next
command instead. (The difference in the command line is the “1” at the
end.)
Example:
Input:
STRIGGER:ASET:55,10,8,80,20,8
Result:
The following values are assigned to the dispensing
parameters:
Rising: 55 ≙ 0.55 ms (ms = Millisecond)
Open Time: 10 ≙ 1.0 ms
Falling: 8 ≙ 0.08 ms
Needle Lift: 80 %
Number of Pulses: 20
Delay: 8 ≙ 0.8 ms
Return:
55,10,8,80,20,8

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
