AT Auto Tuning
CT Current Transformer
DI Digital Input
DO Digital Output
(Control outputs of relay and voltage pulse, and event output)
EV Event
LSP Local Set Point. This value is the SP value stored in the instrument.
MFB Motor Feed Back. This indicates the feed back of motor opening which is used for position proportional control.
MV Manipulated Variable
PV Process Variable
RSP Remote Set Point. This is the set point which is set by the analog input from an external device.
SP Set Point
U Unit. This indicates the minimum digit of the selected PV input range with industrial unit (°C, Pa, L/min., etc.).
1 U = 1 °C in a range of –200 to +200 °C. 1 U = 0.1 °C in a range of 0.0 to 200.0 °C. Additionally, 1 U = 0.01
when the DC voltage input is scaled to 0.00 to 10.00. Furthermore, 0.1 U means 1/10 of 1 U.
