The adjustable stator is preset at the factory to match the nozzle installed in the rotor. The purpose of the stator is to maintain a consistent and desirable speed of rotation. Rotors that turn too fast cannot reach their published radius distance. Rotors that turn too slow will irrigate with a higher precipitation rate per revolution causing wet spots and run-off.

Turn the riser upside down, remove the filter screen and view the stator area. Notice the black part with the three sections extending outward from the center. This black part on G70 and G75 risers is called the adjustable stator plate. Beneath the adjustable stator plate is a gray non-removable part with the three openings. This part is called the stator. The stator has a series of numbers engraved into the plastic. These numbers are the nozzle size reference numbers.

Turn the riser upside down, remove the filter screen and view the stator area. Notice the black part with the three sections extending outward from the center (fig 1). This black part on G80 risers is called the adjustable stator plate. Beneath the adjustable stator plate is a gray non-removable part with the three openings. This part is called the stator. The stator has a series of numbers engraved into the plastic. These numbers are the nozzle size reference numbers.

Line Fault: This display indicates a power or wiring related problem. Generally it will appear if an IDS or VSX controller has detected an Overload condition (transformer current draw in excess of 2 amps), and no stations were scheduled to be running. If there were no stations running but a 2 + amp current was sensed, this would indicate a direct short circuit in the two wire path, or a potential transformer problem.

To test one of the main component behind the two wire path's power supply (Decoder Output Board), follow these steps:

Caution! The riser assembly is under spring tension. Eye protection should be worn and safe-handling procedures followed when servicing this product.

Tools Needed (varies with riser model)

• T-Handle Tool – PN 053191

• Hunter Wrench – PN 461720

• Snap-ring Tool – PN 052510

• Needle-Nose Pliers

• Flat Blade Screwdriver

• Phillips Screwdriver

Electric Valve-In-Head TTS rotors are equipped with a selector to control operation of the rotor. The selector is located on the flange compartment’s lid. From the factory, the selector is set to the AUTO position which is located midway between the ON and OFF positions (fig 1).

Several tools are available to make ON-AUTO-OFF selections:

 

• T-Handle Tool – PN 053191

• Hunter Wrench – PN 461720

• Snap-ring Tool – PN 052510

Prior to removal of the upper snap-ring assembly, the rubberized logo cap must be removed and the riser assembly must be pressed below the snap-ring’s rubberized seal. If the procedure below is not followed, the upper snap-ring assembly cannot be removed from the G900 Series rotors:

 

The first practice in troubleshooting “Revolving Messages” is press the CLEAR button 3 times to remove old invalid messages. When a message is generated, it will continue to be present even if the error has internally corrected. This is by design to inform the user that there is/was a controller incident.

Note: When the term “CLEAN” is stated below, power down the controller and use a soft toothbrush and alcohol to gently break away deposits.

(Image Needed: boards identified)

No display: Check power connections. It's possible the fuse on the power supply board (PSB) has blown, and the controller will not power up until it has been replaced. The fuse is an AGC, 3 amp, fast-blow only.
