53 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. The minimum values for Falling and Rising depend on the Needle
Lift (see paragraph 7.4, page 61).
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:55,10,150,80,20,8,1
Result:
The following values are assigned:
Rising: 55 ≙ 0.55 ms (ms = Millisecond)
Open Time: 10 ≙ 1.0 ms
Falling: 150 ≙ 1.5 ms
Needle Lift: 80 ≙ 80 %
Number of Pulses: 20
Delay: 8 ≙ 0.8 ms
Return:
55,10,150,80,20,8
54 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
55 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

56 VALVE:CHECK:OFF
Description:
This command deactivates the valve check at the start-up of the MDC,
during which the valve is opened very shortly.
The default setting for the valve check is “ON”.
Information:
Even if the valve check is set to “OFF”, you can perform an immediate valve
check with the command VALVE:CHECK:<value>.
Example:
Input:
VALVE:CHECK:OFF
Result:
The valve check will not be performed at the start-up of the
MDC.
Return:
OK
57 VALVE:CHECK:ON
Description:
This command activates the valve check at the start-up of the MDC, during
which the valve is opened very shortly.
The default setting for the valve check is “ON”.
Example:
Input:
VALVE:CHECK:ON
Result:
The valve check will be performed at the start-up of the
MDC.
Return:
OK
58 VALVE:CHECK:<value>
Description:
This command causes an immediate valve check, during which the valve is
opened very shortly. As parameter you enter the Needle Lift to use for the
check. You can enter a value between 1 and 100. This value will correspond
directly to the Needle Lift.
In case you enter a value above 100, the response will be “NAK”.
In case the command is send correctly, but the valve check cannot be per-
formed for technical reasons, the response is “NOT OK”.
Information:
Even if the valve check is set to “OFF”, you can perform an immediate valve
check with the command VALVE:CHECK:<value>.
Example:
Input:
VALVE:CHECK:30
Result:
The system immediately starts a valve check with a Needle
Lift of 30.
Return:
OK

59 VALVE:OPEN
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 31), then the
parameters of scenario 1 are chosen. If the select pins are activated (see
paragraph 7.8, page 64), 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:OPEN
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 66). Usually this is the working configuration (setup 0).
But if in the menu SCENARIO is ON (see paragraph 4.5.5,
page 31
), then the parameters of scenario 1 are chosen. If
the select pins are activated, the setup (or scenario) is deter-
mined by them.
Return:
OK
60 VALVE:OPEN:<RI>,<OT>,<FA>,<NL>,<NP>,<DL>
Description:
This command initiates a dispensing cycle with the parameter combination
currently selected. Time parameters have to be specified in 1/10th 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:<RI>,<OT>,<FA>,<NL>,<NP>,<DL>”,
are valid only until the end of the dispensing cycle. If you intend to use the
combination several times, the complete command has to be repeated at
the beginning 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”.
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:OPEN: 30,10,15,90,20,8
Result:
The dispensing cycle contains the following values:
Rising: 30 ≙ 3.0 ms (ms = Millisecond)
Open Time: 10 ≙ 1.0 ms
Falling: 15 ≙ 1.5 ms
Needle Lift: 90 %
Number of Pulses: 20
Delay: 8 ≙ 0.8 ms
Return:
OK
