Direct Injection: Pump Runs Full Speed
Digital Pump Speed Sensor - The injection pump’s digital pump speed sensor is used to provide actual
rate feedback to the display. If the display is not receiving an actual rate the pump will run full speed and
provide a “Rate Not Responding” warning message. See Digital Pump Speed Pin out table below for pin
locations. With the section valves on the cabling can be tested by pulsing the signal and ground pins to
verify the total applied increases, it is always best to pulse the pins at least 10 times to make sure the
total applied will increase by a noticeable amount.

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.
