Two-Speed Sprinkler Alignment - Models 696 and 698

There are two types of full circle sprinklers which have special arcs of slower then regular speed. Alignment of the heads is critical for proper performance. The model 696 sprinkler is a two-speed head with two 60° and two 120° arcs of speed. A red button on the drive assembly indicates it is a two-speed 60°–120° head and acts as a pointer toward the center of the fairway or the next head in the row of sprinklers. The model 698 sprinkler is a two-speed head with two 180° arcs of speed. A yellow button on the drive assembly indicates it is a two-speed 180° head and also indicates the center of the regular speed side. Align the sprinkler so the button points toward the center of the overlapped area of coverage. When a nozzle assembly is changed on either the 696 or 698 head, the main nozzle must be aligned with the small boss on the bull gear of the drive assembly.

Align main nozzle directly over raised timing mark on bull gear.

Back Nozzle Alignment

When replacing the back nozzle, align it so the nozzles are vertical and the ramp is parallel to the ground. Use a 5/8 in. wrench to remove and align the back nozzle. See example at right.

Pilot Valve Operation

RAMP ALIGNMENT

PARALLEL

GROUND LINE

The main function of the pilot valve is to control the operation of the main valve located in the base of the sprinkler body. The main valve is operated by the release of water metered through the pilot valve when it is activated either manually or automatically by the 24 VAC coil assembly.

Another important function of the pilot valve is to regulate the water pressure to the sprinkler nozzle. Pressure regulation compensates for large variations within the system and maintains a constant pressure for optimum sprinkler operation. The 690 series pilot valve is factory set to regulate at 80 or 100 PSI depending on sprinkler model.

Sprinkler operation mode is set using a Toro Selector Tool (P/N 995-15) inserted through the body flange onto the pilot valve D shaped selector-cam. The "AUTO" mode permits automatic operation from the system controller. The "ON" mode opens the main valve for manual operation and "OFF" mode prevents the main valve from opening.

System Troubleshooting

Pilot Valve

Possible equipment failures with causes and corrective action are listed below.

PROBLEM

POSSIBLE CAUSE – CORRECTIVE ACTION

1.Sprinkler will not turn on (a) No 24 VAC to coil assembly - Measure voltage with DVM.

Check wiring and controller program - Refer to Controller Operating

Instructions.

(b)Selector cam in "OFF" position - Set to "AUTO" position.

(c)Debris in pilot valve assembly - Disassemble and remove all debris (See Servicing Pilot Valve page 8.)

2.Sprinkler will not shut off (a) Constant 24 VAC from controller - Check for voltage using a DVM. If voltage is present, disconnect wire.

If sprinkler closes, service controller. Refer to Controller Service Manual.

(b)Selector cam in manual "ON" position - Set to "AUTO" or "OFF" position.

(c)Debris in pilot valve assembly - Disassemble and remove all debris (See

Servicing Pilot Valve page 8.)
