WHAT TO EXPECT WHILE RECIRCULATION IS ACTIVE
NOTE: When operating in Auto Recirculation Mode, it is recommended to adjust the Standby PWM% value
so that recirculation pressure is close to the application pressure used during application.
When recirculation is active:
• The main product pump runs at the “Standby PWM%” value.
• Section valves will cycle “On” sequentially in pairs from the outermost to innermost sections for the user
defined recirculation time.
NOTE: NCVs on each section will remain off.
• The system will continue to monitor the main flow meter to ensure product is circulating. If the product
recirculation is less than the low limit of the flow meter, the system will display an alert, but recirculation will
continue.
• The boom pressure transducer is monitored to ensure the system pressure stays within the minimum and
maximum allowable pressures. The main product pump will shutdown if the boom pressure exceeds the
minimum (6 PSI) or maximum (150 PSI) pressure.
• Section valves will continue to cycle sequentially unless spraying or shutdown conditions are met.
• The drain valve will be used to drain out any product in the recirculation line when rinsing the boom.
NOTE: It is recommended to rinse the system with the boom unfolded to prevent circulating with pinched
supply hoses.
ALARM SETTINGS TAB
To access the Alarm Settings tab:
1. Open the UT Menu and select the RCM - Sprayer Menu button.
2. Select the Tools Menu softkey along the right side of the display.
3. Select the Alarm Settings tab along the top of the display.
4. Use the Product Channel buttons along the top of the page to select the desired product for the following
alarm options and settings:
NOTE: Alarm settings must be set for each product channel on the system.
OFF PRESSURE ALARM
Toggle the check box option at the far right to enable or disable the Off Pressure Alarm.
When enabled, enter a value between 1 and 100 percent for the allowable difference between the target and actual
product pressure. If the difference between the actual and target pressure exceeds the set percentage for more
than 5 seconds, the system will display the off pressure alarm for the product.
