Note: Shorting across B and B terminal will cause an error
when thermocouple/voltage/current is inputted.
If used with input current, apply supplied shunt resistor
of 250 ±0.1% between input terminals (+,−).

5. Names and Functions of Parts on Front Panel
Name Function
Measured value
display
• Displays measured value (PV) or each type of
parameter signs (red)
Target set value
display
• Displays target set value (SV), each type of
parameter set value
• Output value is displayed by % on control output
monitor screens of the screen group 0 (green)
Action display
• Out (green) /Control output display
• Lights when output turns on during contact or
SSR
dr
ive voltage output.
• Turns off when output is 0% during voltage or
current and flashes continuously
when output is
100%.
• Flashes on a equal basis of 0.5 sec for others.
• EV1, EV2 (orange)/ Ev
ent output display
• L
ights during event output.
• AT (green)/ auto tuning action display
• Flashes when ON key is selected by key on the
AT action selection screen and AT is executed by
key and goes out when AT terminates
automatically or is released.
• MAN (green) /Manual control action display
• Flashes when manual control action mode is
selected.
Operating keys
• Parameter key
• Pressing this key on any screen of the screen
group 0 and the screen group 1 calls the next
screen onto display.
• When pressed continuously for 3 seconds, this
key functions to move toward the basic screen of
screen group 0 and the initial screen of screen
group 1.
• Down key
• When pressed on each of the screen, the decimal
point of the rightmost digit flashes and the set data
decreases or moves backward.
•
Up key
• When pressed on each of
the screen, the decimal
point of the rightmost digit flashes and the set data
increases or moves forward.
• Registration (entry) key
• Used to register a set data changed by means of
or key on a parameter screen. (The
flashing right most digit turns off.)
• When pressed continuously for 3 seconds on the
control output screens (mode 0 to 1), this key
functions to switch between the manual control
mode (Man flashes) and the automatic control
mode (Man turns off).
