Loop Disconnection Detection Dead Band Function - Mitsubishi Electric MELSEC iQ-F FX5 User Manual

4.31
Loop Disconnection Detection Dead Band
Function
Set the non-alert area having the set value (SV) at the center (temperature width in which no loop disconnection is detected)
to prevent accidental alerts of the loop disconnection detection.
When the temperature process value (PV) is within the loop disconnection detection dead band, an alert is not output even
though the loop disconnection alert conditions have been satisfied.
Temperature process value (PV)
Set value (SV)
(1) 'CH1 Loop disconnection detection dead band' (Un\G538) (this band has the set value (SV) at the center)
*1 If internal thermocouple/platinum resistance thermometer inputs selection= 0.8
If internal micro voltage inputs selection= 0.8% of scaling span
If external inputs selection= 0.8% of external inputs span
Setting method
Configure the settings as described below.
