Connect a platinum resistance thermometer with copper wire. All three leads
should have the same thickness and the same length to give them identical re-
sistances. Do not branch the two (B) leads near the terminal block as this in-
creases measurement errors.
Use an E54-CT1 or E54-CT3 Current Transformer (CT). Refer to Appendix C
Heater Burnout Detection for details of the Current Transformer specifications
and installation dimensions.
NC: Not connected
The pairs of terminals B2 to A2 and B1 to A1 are shorted internally. Always sup-
ply power to the 24-VDC terminal (B1) as this drives the internal circuits.
