Pulse Time Setting for Jet-Type Valves
• For jet-type valves, the pneumatically actuated dispensing needle remains open as long as it is triggered. The
Pulse Time directly affects the dispensing volume.
• The Pulse Time of jet-type valves can be set within a range of 2 to 10,000 ms. If the Pulse Time is below 2ms,
correct valve operation cannot be guaranteed.
Oscillogram (Valve Output) for Jet-Type Valves
NOTE: The Pulse Time of jet-type valves corresponds to the opening time of the valve. The dispensing volume can
be adjusted by adjusting the Pulse Time.
Setup (continued)
Pulse Time Setting for Dot-Type Valves
• The Pulse Time must be 2 ms before placing the valve into operation.
• Do not change the Pulse Time for Dot-type valves.
The Pulse Time for dot-type valves must be 2 ms. With dot-type valves, Pulse Time adjustments do not affect the
dispensing volume, but they can cause poor dispensing results.
Oscillogram (Valve Output) for Dot-Type Valves
NOTE: The Pulse Time of dot-type 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 the set screw and is usually shorter than the electrical
actuation time (Pulse Time) by a factor of 5 to 10.
