7. PERIODIC MAINTENANCE The EP1000A itself requires very little servicing because of the following features the use of a laser diode which has a life expectancy of 3 to 5 years and is easy to control In addition an electronic system continuously controls and regulates the power emitted by the laser diode synchronous detection is used to get over the background noise it is fitted with a blowing and ventilation device which prevents the fouling of the optics to a high degree and cools the heat sink of the laser diode it is fitted with an air flow sensor which sets off an alarm and optionally has a device for closure of the protective boot thus preventing fouling of the optics in the event of a blower or mains failure Nevertheless its use on a smokestack and on industrial sites which are very dusty calls for regular servicing Warning the operations and adjustments described in this paragraph are reserved to authorised personnel only Inthe EP1000A unit a lithium battery fig 6 ref F backs up the memory of the micro board and has a life expectancy of 5 years maximum This battery must therefore be changed every 5 years at least check the slaved units controlled by the Alarm and Fault contacts and if necessary change the soldered relays on the main analog board fig 5 ref A and B clean the parts in contact with the blown air and the dust from the smokestack This cleaning must be performed regul
