30 ISO Product Controller II and Hawkeye Operation Manual
SYSTEM SETTINGS TAB - ALARM
To access the Alarm Settings Menu:
1. Open the UT Menu and select the Hawkeye
®
Menu button.
2. From the home screen, select the Tools Menu softkey along the right side of the display.
3. Select the System Settings tab along the top of the display.
4. Select the Alarm Settings button. The following information will display for the product number shown at the
top of the screen:
MINIMUM PRESSURE
The minimum pressure feature will allow the operator to set the lowest tolerable pressure during field operations.
If the application system reaches the minimum pressure, the UT will display an alert and the application system will
maintain the flow rate to keep the monitored pressure consistent and to maintain the spray pattern.
OFF TARGET PRESSURE PERCENT
The off target pressure percent sets the allowable difference between the target and actual pressures. Enable the
off pressure feature and enter a non-zero value to set the allowable difference between target and actual
pressures during field operations. If the difference between the actual and target pressure exceeds the set
percentage for more than five seconds, the system will display an off pressure alarm.
SYSTEM EFFICIENCY LIMIT
The system efficiency limit feature allows the user to monitor system performance. The system will display an
alarm in the actual efficiency exceeds the ideal efficiency by more than the set percentage. Typical efficiency may
range from 90% - 105% during normal operation. System efficiency readings higher than 100% indicate that the
system is delivering more flow than expected for a given NCV duty cycle. If the flowmeter and pressure transducer
are calibrated and operating correctly, and the tip size is selected properly, there may be a system leak after the
flowmeter or a malfunctioning NCV. System efficiency readings less than 100% indicate they system is delivering
less flow than expected for a given NCV duty cycle. There may be a restriction or flow delivery issue to the NCV’s.
LOW TANK LIMIT
Enable the Low Tank Limit feature and enter the desired volume threshold at which a low tank condition alert will
display. Enter a value of zero or uncheck the Enable box to disable the alarm. Manually set the tank volume upon
refilling or the tank fill flowmeter will monitor the tank level.
STUCK POPPET
The stuck poppet alarm notifies the user if the NCV doesn’t detect movement of the poppet. The NCV’s must be
assembly revision G or newer to support this feature. The revision level information is located on the NCV label.
