5. The Daisy Chain configuration utilizes a single run of communication cable with all of the equipment connected in parallel as shown on Sheet No 1 This type of network utilizes the least amount of cable and is probably the most popular approach when long line runs are anticipated Depend ing on the desired reliability of the system some consideration should be given to the effect of a cable break If the cable is broken all ATSs beyond the break will lose their communication It should be kept in mind that annunciator lamps will flash if a disconnec tion occurs Also a disconnection of the communica tions cable will in no way impair the operation of the automatic transfer switch Star networks can be used as an alternate configu ration as shown on Sheet No 2 With this approach greater reliability can be achieved because a discon nect of the cable between the junction box and the ATS will only impair one switch Depending on location of this equipment it may sometimes be advantageous to use combinations of Daisy Chain and Star networks Typical configurations are shown on Sheets No 3 and 4 DISCONTINUED PRODUCT SETTING UP THE ATS ANNUNCIATORS Catalog 214A400 214A404 Maste r ATS Annunciators aaam aae ae n ot a ert on swe sw2 sw on sw4 ea SWS aogoog 4 Tooogg 4 Che tl H Address 0 Address 1 Address 2 Address 3 Master ATS Annunciator factory default settings Figure 5 DIP switches in Master Before applying
