OL: Output low. Low limit setting for the manipulated variable.
OPEN: Open. Motor shaft rotates toward the open position.
PID: Control parameters
P (proportional band)
I (integral time)
D (derivative time)
PTN: Pattern. A series of SP changes during "pattern operation." Consists of one or more segments.
PV: Process variable. Measured value.
RAMP: Ramp Segment. A segment in which the SP changes in pattern operation.
READY: Ready. A standby state in which control operation is stopped.
RSP: Remote set point. Set point through analog input.
RUN: Run. State in which control operations are running.
SEG: Segment. A constituent of a pattern, configured by one set point and one length of time.
SEG-EV: Segment event. Only one segment event can be turned ON in pattern operation.
SOAK: Soak segment. A segment in which the SP is constant in pattern operation.
SP: Set point. The set value (target value).
TP: Time proportioning.
V-P: Voltage pulse.
VT: Voltage transformer.
