7.3 SPRAY TIMING MODES
Timing modes are selected by going to the HMI settings page and selecting the
“
Timing
”
button.
The system will spray for a predetermined time depending on the timing mode selected. The spray controller allows
for accurate time
-
based control over the spray nozzle based on an external trigger signal.
When there is a start delay value of 0 sec., the spray will start immediately after the trigger signal is sent to the 1750+,
and if the stop delay is set to 0 sec. the spray will stop immediately after trigger signal goes low. All delay values can be
set from 0.00 to 320.00 sec., spray times can be set to 0.01 to 320.00 sec.
SPRAY PERIOD
•
The spray period is the time the object remains under the spray nozzle or the time that it takes to dispense a dose.
This will be in time units.
START DELAY
•
The time that the system should wait between a trigger event and the start of the spray.
•
Typically, this is the distance between the sensor and the spray nozzle.
•
The start delay must always be longer than the configured minimum signal length of the trigger.
STOP DELAY
•
The time that the system should wait between the end of a trigger event and the end of the spray. Typically, this is
the distance between the sensor and the spray nozzle.
