Wiring
The following diagram shows the terminal arrangement for CT inputs when a
XW2B-20G5/4 Connector Terminal Conversion Unit is connected. Connect CT0
to CT7 to the CT inputs for control points 0 to 7. For example, CT0 will detect
heater burnout or SSR failure for the output of control point 0.
Use the E54-CT1 or E54-CT3 Current Transformer (CT). Refer to Appendix B
for further details on the CT. Refer to 3-10 Heater Burnout Detection for details
on wiring the CT.
