This& is& the& 0*0.5& Vac& process& input.& This& input& is& used& in& junction& with& a& current& transformer.& The& input& has& a&
factory*installed& current& shunt& attached& between& terminals& 7& and& 5.&The&shunt&converts& 5& Aac& from& the& current&
transformer&to&0.5&Vac.&This&input&signal&represents&the&motor¤t&where&0&Vac&input&represents&zero&motor&
amps& and& 0.5& Vac& input& represents& maximum& motor& amps&(that& is,& the& rating& of& the& current& transformer).& This&
signal&is&displayed&on&the&Operator&Control&Panel’s&digital&display&(1).&When&5&s&is&applied,&it&is&converted&to&0.5&
Vac&and&the&AC*24&Controller&will&display&the&number&set&for&the&Display&Range&(28/29).&The&display&range&should&
be&set&to&match&the¤t&transformer.&For&example:&The&factory&default&display&range&is&set&to&100.0&for&a&100:5&
current&transformer.&If&the¤t&transformer&rating&is&50:5,&the&display&range&should&be&set&to&50.0.&
