Green 5-digit, 7-segment LED
This panel normally displays values. Item codes are displayed in control data setting mode and
alarm codes are displayed when alarms are generated.
Orange 5-digit, 7-segment LED
This panel normally displays SP values. Set values are displayed in control data setting mode.
Orange 2-digit, 7-segment LED
This panel displays the difference between LSP and RSP values in normal indicating mode when
display panel 2 shows SP values. In control data setting mode, item codes are displayed.
12 green and amber LEDs

PID computational units control constants (LSP).
MAN computational units output manual settings. (However, only one MAN
computational unit can be used.)
Only PID computational units perform integral operations.
MAN computational units outputs follow inputs to the SDC40B.
