Page 17: Lens Heating Optional Device
LED PAPI 66 Lens heating optional device The LHA unit of LED PAPI 66 system can be equipped with optional lens heaters. The heater is controlled by a microprocessor system to delete any problem caused by repeated and close on-off cycles and to optimise the relative consumption. The heater is always activated at full power for 25 minutes after the unit is powered on. Subsequently it remains powered at low power to keep the lens warm at about 5 ° above ambient temperature. In any case, if the lens temperature exceeds a certain threshold, the heater is deactivated. Tilt switch optional device The effectiveness of the LED PAPI 66 system is determined by the correct inclination of the light beams of the LHA units installed. If a LHA unit loses the alignment of the correct inclination, can provide incorrect indications to the pilot approaching. Each LHA unit can be equipped with a tilt switch optional device of the LHA unit and, if this deviates by the correct inclination set during installation, the whole LHA units system is deactivated (with a delay of 10-30 seconds, to avoid detection mistakes due to temporary external conditions, such as wind or vibrations). The PAPI system is designed to operate in fail-safe mode: when the LHA units are equipped with tilt switch device, the system becomes operational only if all LHA units are correctly inclined. Tilt switch optional device (mercury-free) The LED PAPI 66 system can be equipped with tilt switch optional device mercury-free type (for applications in areas in which mercury is listed among the substances subject to restrictions). The operation of these components is similar to the one already described in the paragraph related to the standard tilt. Behaviour in case of fault Below are listed the possible types of faults and the behaviour of the failed unit and of other units of the system in the various cases: ●... -
