See Section
4.2.1 Parameter Definition of Terms
- 18 -
4.2.1 Parameter Definition of Terms
Term Explanation
Switching Time (0.1 to 10,000 ms)
Corresponds to the electrical actuation time of the micro dispensing valve. NOTE: see Chapter 4.3!
When ‘infinite’ is ticked off, the valve remains open until the programme is stopped.
Pause between shots (1 to 1,000 ms)
Determines the length of pause between the shots on one dispensing position, as far as several shots are applied.
Pre-selected number of shots (1 to 65,000)
Determines the number of shots.
When ‘infinite’ is ticked off, the valve keeps on dispensing until the programme is stopped.
Switching time single shot (0.1 to 10,000 ms)
Determines for how long the air nozzle remains open after the valve is closed.
PLEASE NOTE – V10 DIGITAL+
The Software for the V10D+ comprises two more parameter settings for actuation of the air nozzle. (see Chapter 6.1)
PLEAES NOTE – COM PORT
In case it is unclear which COM-Port should be chosen, proceed as follows: - Enter the Windows system control.
(Start -> system control) - Select ‘Hardware and Sound’ - Open sub-section ‘Devices and Printers’
Device-Manager - Select Section ‘Inputs (COM & LPT)’ and open it up (click onto the
arrow). - Now it should read ‘Prolific USB-to-Serial Com Port’ and in brackets
‘COM’ with a number. Select this COM-Port.
- 19 -
4.3 Switching Time Settings
The switching time matches the electrical actuation time of the micro dispensing
valve and must be adapted to the corresponding LIQUIDYN valve type (dot or jet
type!
4.3.1 Switching Time for Dot-Type Valves
Actuation of Dot-type micro dispensing valves: (P-Dot / P-Dot ET)
With this type of valve the switching time must be set to 2ms before commissioning.
The switching time must not be altered with this type of valve.
Adjusting the switching time of dot-type valves has no influence on the dispensing
volume, but leads to malfunction of the micro dispensing valve. The switching time of
a dot-type micro dispensing valve is set to 2ms one time only and is never altered.
Oscillogram (valve output):
PLEASE NOTE – ACTUATION
The switching time of dot-type micro dispensing valves does not correspond to the opening time of the valve. The opening time of the valve depends on the settings for working pressure and set screw and is usually shorter than the electrical actuation time (switching time) by factor 5 to 10.
- 20 -
4.3.2 Switching Time for Jet-Type Valves
Actuation of Jet-type micro dispensing valves: (P-Jet / P-Jet CT / Liqui-Jet)
With this type of valve the pneumatically actuated dispensing needle remains open
as long as it is triggered. The switching time of the triggering signal influences the
dispensing volume. The switching time of jet-type valves can be set within a range of
2 to 10,000 ms. With a switching time below 2ms it cannot be guaranteed that the
valve will function properly.
Oscillogram (valve output):
PLEASE NOTE – ACTUATION
The switching time of jet-type micro dispensing valves corresponds to the opening time of the valve. By amending the opening time, the dispensing volume can be altered.
