To install the Danfoss Heavy Duty Series Pump Controls, follow the steps below:

1. Disconnect the battery and ensure that the engine or motor providing power to the pump is not running. Engage the parking brake and disengage any peripheral equipment.

2. Using a 1/4 hex wrench, remove the xxxx holding the clip to the Feedback Sensor connector.

3. Using a 9/64 hex wrench, remove the two screws holding the existing Feedback Sensor.

4. Carefully remove the existing Feedback Sensor and gasket.

5. Install the provided O-ring into the groove on the bottom of the new feedback sensor.

6. Install the new Feedback Sensor into place using the two cap screws and flat washers. Hand tighten the cap screws at this point.

7. Set and Check the Supply Voltage:
a. Turn on the power supply and multimeter and allow a brief warm-up period.
b. Connect the equipment as shown in the installation guide.
c. Set the multimeter to display DC Volts.
d. Record the power supply output to the nearest millivolt. Do not change the supply voltage from this point on.

8. Set the Feedback Sensor Neutral:
a. Assuming the pump is destroked and in neutral, connect the equipment as shown in the installation guide.
b. Rotate the sensor housing counterclockwise until the multimeter indicates the sensor's output is exactly half the voltage recorded in step 7d ± X (X is a tolerance value).
c. Torque the sensor screws to 26.2 ± 2.6 in·lb.
d. After securing the sensor, verify that the sensor's output voltage displayed on the multimeter is still half the voltage recorded in step 7d ± X. This tolerance ensures that the sensor is centered to ± 0.1 degrees about the swashplate's neutral.

9. If the sensor output is out of tolerance, loosen the screws and repeat steps 8b through 8d.

10. Reattach the xxxx holding the clip and connector to the pump. The pump is now ready to return to operation.
