Troubleshooting

Problem

The controller repeats itself or continuously waters, even when it should not be on (cycling repeatedly).

Cause

Too many start times (user error).

Solution

Only one start time per active program is required.

Problem

There is no display.

Cause

Check AC power wiring.

Solution

Correct any errors.

Problem

The display reads "SP ERR".

Cause

Electrical noise is entering the system.

Solution

Check the SmartPort® wiring harness. Verify that the red wire is attached to the AC1 terminal, the white wire to the AC2 terminal and the blue wire to the REM terminal. If the wires were extended then they will need to be replaced with shielded cable. Contact your local distributor for information on shielded cable.

Problem

The display reads “P ERR”.

Cause

There is a fault in the pump start, master valve, or the wiring for the pump start/master valve.

Solution

Check the master valve or pump start wire for continuity. Replace or repair the shorted wire. Check that all wire connections are good and watertight.

Problem

The display reads a station number and ERR, such as “2 ERR”.

Cause

There is a fault in the station solenoid, or the station wiring.

Solution

Check the station wire for continuity. Replace or repair shorted wire. Check that all wire connections are good and watertight.

Problem

The display reads “NO AC”.

Cause

There is no AC power present (the controller is not receiving power).

Solution

Check to see if the transformer is properly installed.

Problem

The display reads “SENSOR OFF”.

Cause

The rain sensor is interrupting irrigation or the sensor jumper is not installed.

Solution

Slide the Rain Sensor switch on front panel to the BYPASS position to bypass rain sensor circuit, or install the sensor jumper.

Problem

Rain sensor will not shut off system.

Cause

  • Incompatible rain sensor or the jumper was not removed when sensor was installed.
  • Manual Single Station Mode Used.

Solution

  • Make sure sensor is micro-switch type such as Mini-Clik®. Check that the jumper has been removed from the SEN terminals. Confirm proper operation (see “Testing the Weather Sensor”).
  • Manual Single Station Mode will override the sensor. Use Manual All Station Mode to test sensor.

Problem

The controller does not have a start time for each station.

Cause

Programming error, dial in incorrect position.

Solution

Be sure the dial is in correct position. Total number of stations can be easily checked by placing dial in the RUN TIMES position and pressing the back arrow.

Problem

Valve will not turn on.

Cause

  • Short in wiring connections.
  • Bad solenoid.

Solution

  • Check field wiring.
  • Replace solenoid.
