Used to switch between the AUTO and MAN modes. Each time you press the key, it switches to the
AUTO or MAN mode alternately.
8.
SET/ENT
key S E T / E N T Used to switch or register a parameter. Pressing the key for more than 3 seconds allows you to switch
between the operating display and the main menu for operating parameter setting display alternately.
9.
Used to change numerical values. On setting displays for various parameters, you can change target
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. To change from the parameter setting (operating or setup) display to the
menu or from the setup parameter setting display menu to operating parameter setting display menu,
press the and keys simultaneously.
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.
REM: Is lit when in remote mode.
MAN: Is lit when in manual mode. The lamp blinks when the controller is being auto-tuned.
Interface for an adapter cable used when setting and storing parameters from a PC.
This requires an optional parameter setting tool.
Displays PV.
Displays a menu symbol when you set a parameter.
Displays an error code (in red) if an error occurs.
Displays a parameter symbol in 3-digit LED.
Displays the setpoint of a parameter in 5-digit LED.
UT450: If any of alarms 1 to 4 occurs, the respective alarm indicator lamp (AL1 to AL4) is lit (in orange).
UT420: If any of alarms 1 to 3 occurs, the respective alarm indicator lamp (AL1 to AL3) is lit (in orange).
