Edit Decoders: This option only appears in VSX/IDS Field Decoder Controllers. Decoder controllers are always configured for 103 stations, plus a Pump output. Each station has a corresponding decoder installed in the field, connected to a two-wire path.

The Edit Decoder function allows you to change the assignments of decoder identification numbers to station numbers in the field.

This can be used whenever a decoder is replaced, added, or exchanged with another decoder, after initial setup.

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.

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.

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.

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:

• Hunter Wrench – PN 461720

• Snap-ring Tool – PN 052510

• Needle-Nose Pliers

• Flat Blade Screwdriver

• Phillips Screwdriver

In hydraulic installations, the flange compartment should be used to make the Control Tubing connections to the rotor. This allows for tubing connections, pressure tests and flushing of the control lines - all without digging.
