Description
The Electronic Transformer is conveniently fitted with an overload power-off device. This feature prevents the installer from damaging the transformer by putting too much glass into the circuit. However, this feature may cause nuisance tripping if the transformer is loaded to just within the maximum limit (refer to data sheet). This is due to the fact that the supply voltage and the load conditions will fluctuate slightly during operation. To avoid this nuisance tripping, it is recommended to bench test the sign and transformer with an extra 300mm length of 15mm Argon (blue gas) filled tubing. If the transformer does not shut down with this extra load, then you can be confident that the loading is correct.
In case of automatic overload power-off, the transformer will then attempt to restart up to 3 times within 10 seconds. Short bursts of power (flashing) are generated during these 10 seconds.
To reset device: switch power off (for at least 10 seconds), correct the fault and then switch power back on.
