Abstract

A modular irrigation controller has a robust ground path with high conductivity that can accommodate lightning induced power surges on field valve wires and common wires that are connected to a plurality of station modules. Sensitive electronic components in the station modules are thereby protected from damage. The robust ground path extends from conductors on circuit boards within the station modules through captive mounting screws to a metallic backplane and then through metallic grounding brackets within a pedestal enclosing the modules and the backplane. The grounding brackets are in turn grounded to both an earth ground stake and to a ground wire associated with the incoming one hundred and ten volt AC power.

First claim

What is claimed is:

1. A pedestal for an electronic landscape controller, the pedestal comprising:
a frame having a hollow interior sized and shaped to receive one or more electronic components and an opening into the hollow interior;
a door supportable by the frame and movable between an open configuration and a closed configuration, the door being sized and shaped to cover at least a portion of the opening when in the closed configuration, the door having a hollow interior, an upper drain hole for water to enter the hollow interior, and a lower drain hole for the water to exit the door and the pedestal;
a receptacle formed in the frame at a location above the hollow interior and configured to receive at least a portion of a control panel, the receptacle having a plurality of side walls, a bottom wall, and an upward opening;
a space formed outside the receptacle and between a sidewall of the plurality of sidewalls of the receptacle and the door at least when the door is in the closed configuration; and
a drip trough, at least a portion of the drip trough being disposed relative to the space to route the water entering the space to the upper drain hole in the door.

2. The pedestal according to claim 1 , further comprising a top cover configured to move between an open configuration and a closed configuration, the top cover covering the receptacle when in the closed configuration.

3. The pedestal according to claim 1 , wherein the receptacle surrounds the control panel.

4. The pedestal according to claim 1 , wherein the space comprises at least one recess, and wherein the at least one recess is sized and shaped to allow a user to move the door from the closed configuration to the open configuration.

5. The pedestal according to claim 4 , wherein the at least one recess is sized and shaped to receive at least a portion of a hand of the user.

6. The pedestal according to claim 4 , wherein the at least one recess is sized and shaped to receive a tool.

7. The pedestal according to claim 1 , wherein the frame further comprises a downwardly facing surface, and wherein the door comprises a peripheral lip configured to mate with the downwardly facing surface to inhibit the water entering the space from entering the hollow interior of the frame at least when the door is in the closed configuration.

8. The pedestal according to claim 7 , wherein the peripheral lip is located above the upper drain hole in the door.

9. The pedestal according to claim 1 , wherein the door further comprises at least a portion of the drip trough.

10. The pedestal according to claim 1 , wherein the drip trough comprises an upwardly opening cross-section defined at least in part by the door and the frame when the door is in the closed configuration.

11. The pedestal according to claim 1 , wherein a least a portion of the drip trough is sloped to route the water entering the space towards the upper drain hole in the door.

12. A pedestal for an electronic landscape controller, the pedestal comprising:
a frame having a hollow interior, at least one side wall, and an opening into the hollow interior, the hollow interior being sized and shaped to receive one or more electronic components, the at least one side wall having a hollow interior and a lower drain hole;
a door supportable by the frame and movable between an open configuration and a closed configuration, the door being sized and shaped to cover at least a portion of the opening when in the closed configuration;
a receptacle formed in the frame at a location above the hollow interior and configured to receive at least a portion of a control panel, the receptacle having a plurality of side walls, a bottom wall, and an upward opening; and
an upper drain hole disposed between the receptacle and the hollow interior of the at least one side wall so as to provide a flow path for the water in the receptacle to enter the hollow interior before flowing through the hollow interior of the at least one side wall and exiting the pedestal via the lower drain hole.

13. The pedestal according to claim 12 , further comprising a top cover configured to move between an open configuration and a closed configuration, the top cover covering the receptacle when in the closed configuration.

14. The pedestal according to claim 12 , wherein the receptacle surrounds the control panel.

15. The pedestal according to claim 12 , wherein the upper drain hole is disposed in the bottom wall of the receptacle.

16. The pedestal according to claim 12 , wherein the lower drain hole is disposed in a bottom surface of the at least one side wall.

17. A pedestal for an electronic landscape controller, the pedestal comprising:
a frame having a hollow interior, a side wall, and an opening into the hollow interior, the hollow interior being sized and shaped to receive one or more electronic components;
a door supportable by the frame and movable between an open configuration and a closed configuration, the door being sized and shaped to cover at least a portion of the opening when in the closed configuration;
a receptacle formed in the frame at a location above the hollow interior and configured to receive at least a portion of a control panel, the receptacle having a plurality of side walls, a bottom wall, and an upward opening;
a space formed outside the receptacle and between a side wall of the plurality of side walls of the receptacle and the door at least when the door is in the closed configuration;
a first drainage path for water to flow from the space and through the door before exiting the pedestal; and
a second drainage path for water to flow from the receptacle and through the side wall before exiting the pedestal.

18. The pedestal as in claim 17 , wherein the first drainage path is separate from the second drainage path.

19. The pedestal as in claim 17 , wherein the first drainage path comprises:
a drip trough; and
an interior of the door.

20. The pedestal as in claim 17 , wherein the second drainage path comprises:
a drain hole in the bottom wall of the receptacle; and
an interior of the side wall.
