Insect (fluorescent) Light Trap Trouble Shooting Guide

Problems

Possible Root Cause

Solution

(Work through the possible causes outlined in sequence under each issue) (Always switch off the unit before any service is done on the unit)

1. Lamps not lit

Power is not getting to the unit.

Check if the power supply is switched on. Try a different socket/power supply.

Check if a supply circuit breaker has tripped the supply.

Check mains lead & fuses if fitted. If in doubt, contact a qualified electrician to do this test.

If all solutions above fail and power supply to the facility is fine, contact your supplier/distributor.


2. Lamps not lit & there is power to the unit

Lamps are not installed correctly

Remove lamps from the unit and reinstall them into the unit.

One or more lamp(s) may be damaged. As the lamps are often in series, if one is damaged; no lamp will light up.

Replace damaged lamp(s).

If unit has starters, then possibility of starter failure.

Replace failed starters.

If unit has an electronic ballast, then possibility of ballast failure. If the unit has an electronic ballast, there will be no starters in the unit.

This is not a user serviceable part and needs to be replaced btqualified personnel. Contact your supplier/distributor.


3. Lamps flickering

Lamp(s) may have reached end of life.

Replace flickering lamp(s).

If unit has starters, then starters may have reached end of life.

Check that installed starters are functioning correctly; and replace as necessary.


4. Killing grid and lamps not working

Safety micro-switch may be open.

Products with high voltage grills have safety micro switches incorporated into the design to cut off the power supply when the catch tray and/or protective grilles are opened or removed. Refit the catch trayand/or close the protective grilles and the power should be restored.

Killing grid not fitted properly.

Ensure killing grid is properly fitted and the grid is connected to the high voltage connectors.

Defective transformer.

This is not a user serviceable part and needs to be replaced by qualified personnel. Contact your supplier/distributor.


5. Insects escaping from unit. Glueboard not trapping Insects

Release paper (protecting the glue) has not been removed from glueboard.

Ensure the release paper has been removed from the glueboard.

Glueboard is saturated with insects with no sections of the glueboard left for newly attracted insects to stick to.

Install a new glueboard into the unit, and ensure the release paper is removed after installation.

Glue on the Glueboard is drying out and losing its stickiness.

Although our high quality glueboards include a UV blocking additive in the glue to prolong the glue's life, glueboards should be replaced every month, even if they are not full. In particularly dry environments, the glueboard may require replacement sooner.


6. Unit not attracting insects

UV light output from the lamps has significantly reduced over time.

Replace lamps with recommended UV lamp type. Optimum UV light waves are emitted for approx. 8000 hrs so as a general rule, lamps should be routinely replaced every 12 months; ideally in early spring.

The unit is located in direct sunlight or other competing UV light source.

Ensure the unit is located away from direct sunlight or other competing UV light sources.

Unit should ideally be strategically placed: to allow easy servicing; near entrances in locations to intercept insects between the entry point and the protected area; in locations where they can not attract insects from outside in; at a height of 3-6 feet above ground level; away from exposed foods; away from extreme sources of heat; away from areas with high air movement; away from areas with high mositure or wet conditions (unless it is a 'Jet Proof' unit).


7. Lamp ends glowing brightly or lamps are flickering

If the unit has an electronic ballast, then the lamp has reached its end of life.

Replace Lamps.

If unit has starters, then starters may have reached end of life.

Check that installed starters are functioning correctly; and replace as necessary.
