TROUBLE-SHOOTING GUIDE

SYMPTOM

CAUSE

CORRECTION

LCD Display is blank

1. Power is off to the Ec Controller

Re-establish power to the controller. If the current time is not shown, or your program is no longer in memory, reprogram the controller.

2. If under battery power, the controller may be in "sleep" mode.

Press any button to reactivate the controller.

LCD is partially or completely blank.

3. An electrical surge or lightning strike may have affected the controller's electronics.

Turn off the controller and disconnect the 9 Volt battery. let the controller sit for two or three minutes. Then reconnect the battery and restore power to the controller. Reset the date and time as described beginning on Page 12 of the Manual.

It the electrical surge did no permanent damage, the controller will accept programming commands and function normally. It the controller does not operate properly, contact Rain Bird Technical Assistance. In Europe, or outside the United States call your Rain Bird Dealer

Display shows a station operating, but no watering occurs

4. The valve may have a defective diaphragm, a clogged pilot port or other malfunction.

Check and repair the valve.

Program does not begin watering as scheduled.

5. Programming dial is set to OFF position.

Set the programming dial to AUTO.

6. Start time has not been properly entered for the program.

Turn the dial to PRGM START TIME and check the start times entered for the program. If the start time is missing or incorrect, enter it as described on Page 16 in the Manual.

7. Today may not be set as a watering day for the Program.

If today is a watering day for a program, the program letter appears in the display. Turn the dial to WATER DAY to check the watering days for the program. It necessary set watering days as described on Page 15 of your Manual.

8. Water supply may be shut off.

Make sure water supply line has pressure.

A particular station does not come on as scheduled.

9. No run time has been set for the station

Turn the programming dial to STATION RUN TIME to check the run times set for the station. To add a run time, see Page 17.

10. A short circuit in the Solenoid or valve wiring has disabled the station.

Identify and repair the fault in the electrical circuit.

11. A start time has not been entered for the station's assigned program

Turn the dial to PRGM START TIME and check the start times entered for the program. If the station's start time is missing, enter it as described on Page 16.

Watering starts when it should not.

12. An unwanted program start time may have been entered.

Turn the dial to PRGM START TIME and check to see if any programs have an unwanted start time. See the instructions beginning on Page 16 for setting and deleting start times.

Watering does not stop as scheduled.

13. Programs may have accidentally been set to overlap.

Check to see if another program's start time began during the previous program's run cycle. The overlapped program would immediately follow the earlier one. Reprogram if necessary.

14. A valve is stuck in the open position.

Turn the programming dial to OFF and wait 10-20 seconds. If the irrigation does not stop, shut off the valve manually and repair the valve.

LCD display shows ERR

15. The automatic circuit breaker has detected an electrical problem

The "ERR" in the display indicates a short circuit or electrical overload on a particular station. The station's number should also be displayed. For example "2 Err" means the problem is in the circuit for Station 2.

Usually, the short circuit is in the solenoid on the electric valve, but shorts can also occur in the wire connectors at the valve. Occasionally, nicked or "skinned" field wires can cause a short. A large pump start relay can also produce a momentary overload that may be detected by the controller.

Locate and repair the cause of the short circuit. See Diagnostic Circuit Breaker on Manual Page 6 for instructions on clearing the problem indicator from the display and testing the station.

LCD display shows an ERR for a few seconds and then shows the station operating for a few seconds.

16. Same as Cause #15.

See correction for Cause #15.

Replace 9 Volt Alkaline Battery [Energizer] every 12 Months.
