LX - Troubleshooting Overview

Problem

No power at plug

Cause

  • Tripped breaker or GFCI

Solution

  • Reset circuit breaker in main panel or the GFCI usually located in a bathroom, garage, or kitchen.

Problem

GFCI keeps tripping

Cause

  • Ground problem or defective GFCI

Solution

  • Use a high-grade model such as the Hubbell #GF5252I.

Problem

One cable run not working

Cause

  • Cut cable or short

Solution

  • Test cable for voltage. If none, it is cut. If there is very low voltage and the cable is hot, there is a short. Check all fixtures and splices for defects.

Problem

Lamps are burning out prematurely

Cause

  • Excessive voltage at lamp

Solution

  • Drop the affected cable run down to the next lower voltage tap or increase wattage load on that cable to drop voltage. Also, some lamps are rated for a very short life such as the 4414 (300 hours). Use halogen lamps.

Problem

The closest lamp to the transformer is burning out prematurely

Cause

  • Excessive voltage at lamp

Solution

  • The closest lamp will always have a higher voltage reading than the last lamp. Cable fixtures so that there is about 40' from first to last within a lighting zone. See system layout for details.

Problem

Lamps have a yellow or golden tone

Cause

  • Voltage too low

Solution

  • Move affected cable to the next higher voltage tap or reduce load on cable. If possible, run additional cable to first fixture to reduce voltage loss.

Problem

Lamp goes on and off when fixture is moved

Cause

  • Too much tension on socket leads

Solution

  • With spring type sockets, it is important to leave some slack so the socket contacts make a good connection to the lamp base.

Problem

System is getting dimmer with age

Cause

  • Splices are corroding

Solution

  • As non-waterproof splices corrode, they create electrical resistance, which reduces voltage.

Problem

Photocell transformer is coming on too soon

Cause

  • Transformer is in dark location

Solution

  • In order to operate properly, the photocell must have a good look at daylight. Move to a brighter location.

Problem

Fixtures have a white mineral deposit on them

Cause

  • Irrigation water is hitting them

Solution

  • Schedule the irrigation to come on after the lights have gone off. This is especially true with the 50 W spots — very hot.
