Reference Conjunction Compensation (RJC)
The Burn-Out (B.OUT) function determines the control outputs including PV up/or down scale, retransmission output and Alarm
when an input disconnection/failure occurs (such as sensor). The Burn-Out is used in the input range of Thermocouple and RTD.
•When the Burn-Out is detected (B.OUT=UP, DOWN), the retransmission and alarm operation is affected and a Control
Output is the Preset-Out.
•When the Burn-Out is not detected (B.OUT=OFF), the PV is rejected and a Control Output is normal (No Preset-Out occurs).
•-OVR or OVR presents on PV Display when the PV is in either -5% or 105% of the input range.
(a controller runs as per either -5% or 105% of PV)
• PV > EU (105 %): PV=105 %, PV Display= OVR
• EU(-5 %) ≤ PV ≤ EU(105 %): PV= PV
• PV < EU (-5 %): PV= -5 %, PV Display=-OVR
•The error message presents on PV Display when an A/D error occurs.
•A controller runs an alarm and retransmission operations as per 105% of PV.
● Lock Functions
Key, Menu, and Password locking prevents the accidental or unauthorized change.
•The reference conjunction compensation is automatically performed when the input type is a Thermocouple.
•When the RJC error occurs, the error message and PV presents on PV Display and a controller runs as per RJC=0 ℃.
