ISOBUS PRODUCT CONTROL NODE CALIBRATION
OFF RATE PERCENT
Enter the percent at which the off rate alarm will activate. The off rate alarm activates when the actual rate differs
from the target rate by the programmed value for longer than five seconds.
RPM OFF RATE PERCENT (GRANULAR APPLICATIONS ONLY)
Set the percent at which the RPM off rate alarm will activate. The RPM off rate alarm activates when the actual
RPM differs from the target RPM by the programmed value for longer than five seconds. See the Spinner/Fan
Control Setup section on page 22 for details on calibrating an RPM control valve.
DUAL ENCODER ERROR PERCENT (GRANULAR APPLICATIONS ONLY)
In Gran 3 (dual bed, dual encoder) systems, a dual encoder error may be displayed when the encoder rates differ
by the selected value for more than five seconds.
NOTE: The dual encoder error alarm prompt will not be displayed if the control type is not set to Gran 3.
BIN LEVEL SENSOR (GRANULAR APPLICATIONS ONLY)
If a bin level sensor has been installed, enable this alarm to alert the operator when the level of product remaining
in the bin falls below the bin sensor.
LOW LIMIT PRESSURE SETTING
Enter the desired pressure for product at the pressure transducer location.
NOTE: The product control valve will stop closing then the low pressure setting is reached.
LOW SUPPLY PRESSURE SETTING (ACCUFLOW HP PLUS APPLICATIONS ONLY)
Enter the desired minimum supply pressure that must be measured to allow the boost pump to engage.
NOTE: The product boot pump will disable when the low pressure setting is reached.
LOW PRESSURE ALARM (ACCUFLOW HP APPLICATIONS ONLY)
The low pressure alarm is displayed if the control type is set to ‘NH3 Applicator’ and requires a transducer to
measure the pressure of the anhydrous ammonia product currently being applied. Enable the low pressure alarm
and enter a percentage value below the target pressure which the VT console will display an alarm condition.
NOTE: The product control valve will stop closing when the Low Pressure setting is reached.
PUMP FAULT ALARM (ACCUFLOW HP PLUS APPLICATIONS ONLY)
A pump fault alarm will signal and eventually the pump control will be disengaged if the pump control reached it’s
maximum value but the outlet pressure did not increase above the inlet pressure.
