setpoints, parameters, and output values (in manual operation). Pressing the key decreases a
numerical value, while pressing the key causes it to increase. You can hold down a key to gradually
increase the speed of change. These keys also switch between menu displays when a main menu or
submenu of parameter setting display is shown.
A/M
When lit, indicates the status of a deviation (PV - SP).
: Is lit (in orange) if a deviation exceeds the deviation display range.
: Is lit (in green) when a deviation is within the deviation display range.
: Is lit (in orange) if a deviation falls below the deviation display range.
The deviation monitor goes off if any display other than the operating display or SELECT display is shown.
Is lit (in green) to indicate the status of operation or control.
CAS: Not used in single-loop control.
REM1: Is lit when in remote mode.
REM2: Not used in single-loop control.
MAN1: Is lit when in manual mode.
MAN2: Not used in single-loop control.
STP: Is lit when operation stopped.
Is unlit when a setup parameter setting display is shown.
