Speed Transducer for the Pump
The speed transducer that measures rotations per minute (RPM), is
located at the inner side of the PTO shield.
The sensor is an inductive type, which requires metallic protrusions to
pass by it to trigger a signal.
If exchanging the sensor, it must installed accurately to function
properly.
Adjustment
1.
Adjust the air gap (A) between sensor tip and the protruding
pump part by turning the counter nuts at the support bracket for
the sensor.
The air gap (A) must be set to 1 mm (+0.3/-0.0 mm).
Use a feeler gauge or similar tool to verify.
2.
Verify transducer function on the controller:
•
HC 5500:
Correct fitting is indicated by continuous flashing from
transducer, when the shaft is rotating.
Level Indicator Adjustment
Regularly check the level indicator reading. When the tank is empty, the
float should lie on the stop pin (D) of the rod, and the indicator O-ring
positioned at the top position line (A).
If finding any deviation, do the following:
1.
Pull out the plug (B).
2.
Loosen screws (C).
3.
Adjust the length of the cord, until it reads correctly.
4.
Push the plug (B) back into place.
÷
NOTE! To obtain the best accuracy, do the adjustment with the
sprayer attached to the tractor normally used.
Level Indicator Cord Renewal
If changing the level indicator cord, then remove the float guide pole:
1.
Remove the tank drain valve (see the following section “Drain Valve Seal Replacement”) and loosen the fitting holding
the pole in position.
2.
Pull the pole down through the drain valve hole, until it is free in the top of the tank.
3.
Now take out the pole through the filling hole in the top of the tank.

DANGER! Do not enter the inside of the tank - it is possible to replace all parts from the outside of the tank!
