6.5 VARIABLE SPRAY TIMING
This timing mode is used to create spray pulses with variable length. The lengths of the spray pulses depend on the
specific time delays between the rising and falling edge of the trigger input.
INCREASING AND DECREASING SPRAY LENGTH
The 2850+ will spray exactly as long as the object has been detected by the sensor when the Start/Stop Spray Delay are
the same. This delay should then be equal to the time/distance delay between the position of the sensor and the
position of the spray nozzle.
The spray distance (or time) will now always be exactly the same as the object length (or time).
INCREASED SPRAY LENGTH
•
Decrease Start
-
delay: The spray is started before the object has reached the spray nozzle.
•
Increase Stop
-
delay: The spray continues after the object has passed the spray nozzle.
