2. SETTING UP REGIONS AND RELAYS For some systems it may be helpful to divide a circuit of sensing cable into regions In addition regions are sometimes useful in setting up TT NRM relay actions When a length of sensing cable is divided into regions the TTDM 128 will identify the region in which a Service or Leak event occurs Each region represents a section of the entire length of sensing cable Regions are defined by a Start starting distance and an End ending distance Regions can contain the entire sensing circuit or only a part of the circuit TO CREATE REGIONS FOR A CIRCUIT REPEAT FOR EACH DESIRED REGION Select the appropriate SIM channel Use the DOWN arrow key to select Add Regions Relays then press ENTER Select Region No from the menu and press ENTER e Use the arrow keys to select a region 1 10 and press ENTER Select Start from the menu and press ENTER This value represents the starting distance for the region Using the arrows enter a starting distance and press ENTER Select End from the menu and press ENTER This value represents the ending distance for the region Using the arrows enter an end distance and press ENTER Select ID from the menu and press ENTER Using the arrows assign the region an alphanumeric label and press ENTER If a TT NRM is connected and will be utilized with this region continue as follows IMPORTANT Each TT NRM leak alarm relay can only be assigned to a sing
