7 RoHS

The starters meet RoHS requirements (Reduction of Hazardous Substances).

The glass used (bulb, exhaust stem, flare) is lead-free.

8 Disposal

The starters may be thrown away with household waste.

9 Troubleshooting

9.1 Observation: the lamp fails to ignite, the starter switches without interruption

Cause:

The lamp voltage is too high (lamp at the end of its life)

Remedy: Replace the (compact) fluorescent lamp and starter (ST 111 LONGLIFE/ ST 151

LONGLIFE)

9.2 Observation: the lamp fails to ignite, the DEOS

SAFETY starter has reacted

Cause:

The lamp voltage is too high (lamp at the end of its life)

Remedy: Replace the (compact) fluorescent lamp and press the red button on the starter

(disconnect from the power supply first) (DEOS

ST 171, ST 172, ST 173 SAFETY)

9.3 Observation: the lamp fails to ignite, the electrodes glow, the starter does not

switch

Cause:

The bimetallic switch on the starter is stuck or there is a short-circuit at the compensating capacitor.

Remedy:

Replace the starter – replace the old lamp at the same time.

9.4 Observation: the lamp fails to ignite, the electrodes glow, the SAFETY starter

has reacted

Cause: The bimetallic switch on the starter is stuck or there is a short-circuit at the compensating capacitor.

Remedy:

Replace the starter – replace the old lamp at the same time. Press the red button on the

new DEOS

starter (disconnect from the power supply first).

9.5 Observation: blackening of the ends/blackening near the electrode coils

Cause:

Oxide sputtering at end of life

Remedy: Replace the (compact) fluorescent lamp and starter (ST 111 LONGLIFE/ ST 151 LONGLIFE)

Remedy:

Replace the (compact) fluorescent lamp and press the red button (DEOS

starter ST 171,

ST 172, ST 173 SAFETY) (disconnect from the power supply first)

Cause:

Extremely frequent switching

Remedy:

Eliminate abnormal operation
