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
