4-1-8 Burn-out Detection (B.SL)
▪ When Sensor signal input is interrupted because of sensor burn-out or line break-off , PV will be
set a certain value so that the operations, alarm action, PV retransmission, control output should
be set with the PV.
▪ B.SL is used when the input type is in TC, RTD group.

▪ Detection case (B.SL = UP, DOWN) : retransmission and alarm action is affected.
MV should be Preset Output value.
▪ Non-Detection case (B.SL = OFF) : PV will be Indefinite
Preset Output will not work.

4-1-9 Reference Junction Compensation (R.SL)
▪ Compensation of reference junction temperature for TC input group is automatically done.
▪ In most cases, R.SL should be “ON” because the TC voltage decreases by the emf of terminal
temperature. If R.SL = OFF, the deviation in PV by terminal temperature will appear.
▪ In RJC ERROR situation, error message and PV is displayed in PV FND alternately and the control
will continue with RJC = 0℃.
