Direct Injection: Application Error; Direct Injection: Discharge Flow Sensor Error - Ag Leader EDGE User Manual

• Analog Pump Speed Sensor
The injection pump's analog speed sensor is used in conjunction with the digital pump speed sensor to
provide accurate rate feedback. The sensor is a generator that produces a varying voltage dependent on
the speed of the pump. The injection module will only get feedback from this sensor when the pump is
rotating. If the analog sensor is not providing a feedback to the module, the pump will run full speed and
the user will not have the ability to manually change the speed.

The injection module requires that a pump calibration be performed
before actual application can occur. The calibration number found
on the tag of the injection pump's digital speed sensor needs to be
divided by a factor of 10 before entering it as the factory calibration
number. If the factory cal number is entered wrong, the pump
calibration routine will not finish due to a high application error.
Notes:
• The pump calibration will fail if error is >10% from the factory
calibration number.
• If the calibration fails, check pump and plumbing for physical
damage or excess wear.
The discharge flow sensor is used as a system check to
see if product is actually exiting the output of the pump.
The sensor is a shuttle valve that allows feedback for
every stroke of the pump. If the user has enabled the
Flow Monitor Warning the display will provide a
message if the discharge flow sensor falls out of its
calibrated value. See table below for pin locations.
