1. The ZAPP receiver must receive a minimum supply voltage of 20 Vac If long power or output wire runs are required a voltage drop due to Ohm s Law I x R line loss must be con sidered This line loss can result in a significant increase in total power required and thereby affect transformer sizing This means that some volts will be lost between the transformer and the ZAPP receiver Because all transformer output voltage levels depend on the size of the connected load a larger transformer outputs a higher voltage than a smaller one for a given load Fig 6 shows this voltage load dependence 27 26 25 24 23 22 SECONDARY VOLTAGE 100 OF LOAD 200 M993 Fig 6 NEMA class 2 transformer voltage output limits There are three ways to adjust the output level 1 Use a larger transformer 2 Use heavier gauge wire for the power run 3 Locate the transformer closer to the ZAPP receiver The issue of line loss is also important in the case of the out put wiring connected to the Triac digital outputs The same formula and method are used The rule to remember is to keep all power and output wire runs as short as practical Use the heaviest gauge wire available up to 14 AWG 2 0 mm with a minimum of 18 AWG 1 0 mm for all power wiring operation if the primary voltage drops to 102 Vac 120 Vac minus 15 or 193 Vac 230 minus 15 To meet the National Electrical Manufacturers Association N2. heavier wire for longer 60 C rating effects on power runs consumption NOTE PVC wire must not be used where prohibited by local fire regulations ENOB 0286 R0101 ZAPP RECEIVER SYSTEM ENGINEERING Step 5 Ordering Equipment Order equipment after compiling a bill of materials through completion of the previous application steps Table 4 ZAPP Ordering Information Part Number Product Description Comments ZAPP receiver W7070 A 1000 ZAPP handhelds RT 7070A 1008 Echelon Based Components and Parts 209541B FTT Termination Module Two required per LONWoRKS network segment Cabling Serial Interface Cable male DB 9 to female DB 9 or Obtain locally from any computer female DB 25 hardware vendor Belden 9H2201504 LONWoRKS network plenum 22 AWG twisted pair Level IV 60 C rating Europe solid conductor nonshielded Belden 9D220150 LONWoRKS network non plenum 22 AWG twisted Level IV 60 C rating Europe pair solid conductor nonshielded CD ROM CARE CD Contains all of the DRF s Data Resource Files which At present no plug ins are available you will need to adjust the configuration of the network variables Step 6 Configuring the ZAPP Receiver General The configuration process involves providing the ZAPP receiver with information using the LonMaker tool or other LNS based tool Commissioning Commissioning refers to th
