DISTANCE BASED SPRAY TIMING
The fixed and variable spray length timing modes have an alternative in which distances are used instead of time.
These modes are called
fixed spray distance
and
variable spray distance
. In these modes, delays are expressed in
distance units. These are the units that were chosen when calibrating the frequency input.
The anticipator time in this mode has a special behavior, it is converted to a distance using the maximum speed,
meaning that it is a minimum anticipator time. At speeds below the maximum speed, it will be longer.
ANTICIPATOR/FOLLOWER TIME
The system will start spraying when it receives a
“
trigger
”
signal and stop when the trigger signal is removed.
If your system is equipped with an air atomizing nozzle the 1750+ will switch the air output on before it starts spraying
to allow the spray pattern to develop fully. When the system stops spraying, the air will continue for a short period
after to guarantee no large droplets can drip off of the nozzle. These times always reference from the spray timing.
Max time for both is 10 s.
Note:
The anticipator time must not be shorter than the start delay time set in the timing settings.
When a spray pattern is generated where the off time < (anticipator time + follower time), the air output remains on
for the duration of this pattern.
