Appendix F: Troubleshooting

SYSTEM PROBLEMS

Effective troubleshooting means you follow logical steps and always check out a problem in this order:

1. TD200 Controller (clock).

2. TWIG units.

3. Solenoids.

Don’t go out to the eld TWIGs until you have learned all you can from the TD200 controller. It

is more often the eld connections or the solenoid than the controller but too much time can be

wasted if it is the controller. Check the displayed information about each eld TWIG battery voltage

and solenoid. This can usually be done at the controller location unless the controller is down.

A good tool to have is a volt/amp

meter and a screw driver.

Carry several fresh ‘D’ cell batteries.

TD200 TROUBLESHOOTING

In the event the valves are not responding to commands

from the controller.

1. Conrm that the cables are plugged in correctly for power and for the antenna is securely

connected.

2. Verify that the TD200 programming was saved and the right dial rotated to the ‘RUN’ position.

3. Make sure that the TD200 is setup to TD200 control.

4. Check to make sure the TD200 is communicating with all the TWIGS and that there are no ?

marks or low batteries on the TWIGS. Also check on the TD200 for open circuit messages for

any of the valves.

5. Reset the controller network using the following steps:

a. Put the left dial in the ‘SETUP’ position.

b. Move down to the ‘Setup Twigs’ line and press ‘ENTER’.

c. Move down to the ‘Reset Network’ line and press ‘ENTER’. Then Exit. This reset method

is a good way to clean up any TWIGs that have accidentally joined to the TD200.

OR

6. Reset the controller using these power cycle steps:

a. Power down the TD200 by unplugging it from electricity.

b. Power the TD200 back up.

c. Watch that all the TWIGs are communicating with the TD200 and there are no errors.

d. Verify the proper TWIG numbers are assigned and the + shows in the selection column for

all valves that are to be in a group.

e. Make sure the proper TWIG address number is assigned to the proper valve.
