For troubleshooting of the Tucor Hybrid 3D, it is necessary to remove the cover to view the LEDs.
The 3D board has 4 LEDs:
- Act/Err (Activation/Error)
- ST (Station)
- MV (Master Valve)
- FS (Flow Sensor)
The Act/Err LED indicates the error while the other three LEDs indicate where the error is. The Act/Err LED will be solid green when the 3D is powered on and idle. If not on, check the power source and wiring. The Act/Err LED will flash red to indicate an error.
The ST LED indicates which station has the issue (e.g.: 4 blinks = station 4).
The MV LED indicates the master valve is the issue
The FS LED will flash red if a 3D-FMV is not detected by the 3D. This is normal if you do not have a 3D-FMV or 3DSD-100 installed. It does not detect the actual presence of a flow meter on the flow meter inputs of the 3D-FMV decoder.
| Code | Error | Cause | Action |
| 10 | Short circuit on two-wire path. | The two-wire output of the 3D is short circuited in the field. The output of the 3D is disabled. | Check the two-wire path for issues, including decoders and splices. Perform short finding. |
| 20 | Station activation error - current consumption exceeded. | Decoder output shorted, no decoder connected, no solenoid connected, wrong solenoid type. | Check decoder, solenoid, and splices. Remove cover to view ST or MV LED to determine which decoder. |
| 21 | Station activation error - too many active stations. | Too many stations have been activated at once. | Deactivate one or more stations. Remove cover to view ST LED to determine which decoder. |
| 25 | Flow sensor check failed. | Flow sensor not present during test. | Connect a flow sensor. |
| 30 | Decoder programming - no decoder detected. | Connect a decoder. | |
| 31 | Decoder programming - wrong decoder type. | Use the correct decoder type. | |
| 32 | Decoder programming - verification failed. | Reconnect decoder and try again or replace decoder. | |
| 33 | Decoder programming -operation timed out | Station programming took too long and the 3D reverted to normal operation. | Perform decoder programming more quickly. |
