FPSL A for LED |

System design |
The LED pitch illuminance system must be split into two independent sources: primary and secondary. Each of the two independent LED systems must operate effectively and produce uniform illuminance across the pitch. They must be supplied and operate completely independently of each other and not be reliant upon the operation status of the other system or of the pitch lighting control system. |

System functionality |
In normal operation mode, each of the two sources supplies power for 50% of the full illuminance level uniformly across the pitch. Each source must have sufficient capacity to supply the entire floodlight system in the event of a failure. If one source fails, the other source must take over the extra 50% in a fully automated switchover process within less than 15 seconds. Switching back from the backup mode to the ‘normal’ operation must be manually controlled from the moment the primary power supply is recovered. |
