3.19 Fault finding

-tube blackening,

-lamp type and wattage must correspond to that required by ballast label,

-lamp orientation designation incorrect for application (base up, base down).

1B:Visual inspection of components

-damaged ballast, starter or capacitor,

-evidence of moisture or excessive heat,

-loose, disconnected, pinched or frayed leads,

-incorrect wiring,

-ballast, starter and capacitor must correspond with lamp type and lamp wattage for the actual mains supply voltage.

1C:Visual inspection of installation

-incorrect wiring,

-blown fuses, switched circuit breakers or contactors,

-hot cables,

-damaged lampholders.

1D:Visual inspection of mains supply

Verify that the correct line voltage is being supplied and that phase and neutral are connected in accordance with the the wiring diagram.

2: Quick fix for restoring lighting

After the visual inspection and repair, replace any defective component, starting with the lamp and glow-switch starter.

3:Trouble-shooting checklist

When, after following points 1 and 2, a failure still exists, some tests will have to be carried out.

Fault I: lamp shows bright flash and does not ignite again.

• Possible cause:

-no ballast, incorrect ballast, short-circuited ballast,

-capacitor across the lamp instead of across the mains.

Fault II: newly replaced lamp does not ignite.

• Action:

-disconnect starter and measure mains voltage and open-circuit voltage at the lampholder.These must both be equal in case of a linear coil,

-if equal, replace the starter,

-if not equal, replace the ballast,

-if equal and not igniting with new starter and lamp, check lampholder and circuit contacts.

Fault III: lamp remains in glow stage, does not ignite properly or only lamp ends (electrodes) do emit some light.

• Possible cause:

-lamp was damaged in previous overload,

-starter defect or short-circuited.
