Single leakage The abbreviation LE stands for single leakage measurement measurement The displayed value shows the annual operating load times due LE to leakage Continuous leakage The abbreviation Le stands for continuous leakage measure measurement ment The displayed value shows the annual operating load Le LC times due to leakage When the abbreviation LC is displayed continuous measure ment has been carried out for more than a week In case of single leakage measurement a single measurement operation over six hours serves to determine the hourly operating load times per year due to leakage In order to obtain a precise value it is imperative that no operational com pressed air consumption take place during measurement resp production is to be shut off for at least six hours If measurement is actuated by means of the control system measurement will be deferred by six hours This allows you to activate the leakage function already in the afternoon causing the measur ing operation to start in the evening six hours later to continue over night Unlike continuous value measurement single value measurement is also pos sible if several compressors are being operated in the basic load mode at the same time Starting separate single value measurement of each compressor enables you after a six hour measurement period to read and to add up all of the single values of the compressor control units Their total v
