Cr4320-30
An external current transformer may be used with the transmitter by The scaling factor may be changed by threading the primary current- routing the secondary leads through the window opening. Use the carrying wire several times through the window opening. The "actual" CR4320-5 current transmitter when using a 5 Amp secondary measurement range will be the name plate range divided by the number instrument grade current transformer. For additional details on current of wire passes. For example, the CR4320-30 has the name plate range transformers, see page 25. of 0-30 Aac. Two passes of the wire through the window opening will then provide an effective range of 0-15 Aac (30÷2). Heaters Controls And Sensors Ltd., www.hcs77.com Toll Free: 800 - 279 - 9912 9
