PV/SV display (red): Indicates the input value and setting value. During setting mode, characters
and setting value of the setting item are indicated in turn.
MEMO/STEP display (green): Indicates memory number during fixed value control. Indicates step number
during program control.
PV indicator (red): Lights up when the input value (PV) is indicated.
SV indicator (green): Lights up when main setting value (SV) is indicated.
AT indicator (yellow): Flashes during AT (auto-tuning).
T/R indicator (yellow): Flashes during serial communication (Lit while sending data, Unlit while
receiving data)
OUT indicator (green): Lights up when control output or OUT1 (Heating side, option Heating/Cooling
control) is ON. (For DC current output type, it flashes corresponding to the
manipulated variable in a 0.25 second cycle)
