ＭＡＣ３Ｂ４８×９６ size front
4-2. Explanation of front panel section
① : Display of measured value (PV) (red)
Measured value (PV) and type of setting is displayed on each setting screen.
② : Display of target value (SV) (green)
Target value and set value are displayed on each setting screen.
③：Monitor LED
(1) RUN monitor LED RUN (green)
If RUN is performed with RUN key, operation mode1 screen, external control input (DI), and
communication, it lights up, and put out by standby (reset). It blinks, if a manual output is
chosen in output monitoring screen or external control input (DI).
(2) Program functional monitor LED PRG (green)
Lights up at the time of program control's standby or flat part control. Puts out at the time of
FIX control selection.
(3) Auto tuning operation monitor LED AT (green)
If AT is chosen in ON or external control input (DI), blinks during AT execution. Lights up
when AT is on standby, and puts out with AT automatic termination or release.
(4) control out put 1 monitor LED OUT (green)
At the time of a contact or a voltage pulse output, the it lights up with ON and lights off with
OFF. Lights off with 0% power output, and lights up with 100% power.
And blinks in intermediate ratio.
(5) Event output monitors LED EV1 and EV2 (yellow)
Lights up when the allotted event output turns to ON.
(6) Control out put 2/event output 3 monitors LED OUT2/EV3 (yellow)
When control output 2 is chosen, it operates like control output 1 monitor LED does.
When event output 3 is chosen, it operates like event output monitor LED does.
④： Key-switch section
(1)
(MENU)key
Press this key to move onto the next screen among the screens.
Press
(MENU) key for three seconds on the basic screen, then it jumps to the
lead screen of Mode 1. Press
key for three seconds on the lead screen of each
Mode screens, then it jumps to the basic screen.Press
key for three seconds on
the lead screen of FIX or PROG, then it jumps to the basic screen.When a
program control option is added, press
(MENU) key for three seconds on the
screen of operation mode 2, then it jumps to the screen of operation Mode 1.
(2)
(DOWN)key
Press
(DOWN) key one time, and the shown value decreases by one numerical value.
One time press of
key decreases by one numerical value. By pressing the key
continuously, the value as well consecutively decreases. A decimal point of the smallest digit
blinks at this time. This shows that a setting change is in progress.In PROG, used as a shift key
between each step setting screens(Steps 1-25) ,lead screen.Also used as a shift key between
lead screen in each mode screens.
(3 )
(UP) key
Press
(UP) key one time, and the shown value increases by one numerical value.
By pressing continuously, the value By pressing the key continuously, the value consecutively
increases. A decimal point of the smallest digit blinks at this time. This shows that a setting
change is in progress. In PROG, used as a shift key between each step setting screens (Steps
1-25), lead screen. Also used as a shift key between lead screen in each mode screens.
(4)
(ENTRY/REGISTER)key
The setting data changed on each screen is determined (the decimal point of the minimum
digit is also lighted off).
When a program control option is added, press
(ENT) key for three seconds on the screen
of operation mode 1, then it jumps to the screen of operation Mode 2.
Press
key for 3 seconds on the output monitoring screen,then the shift between manual
output and automatic output is carried out.
Press the key for 3 seconds on the basic screen, then it shifts to FIX or PROG head screen.
Push at FIX-PROG and each mode screens' lead screen, then shifts to setting screen.
(5)
(RUN OPERATION/STOP)key
Push for 3 seconds at STBY (control stop), then FIX or PROG control starts.
Push for 3 seconds while FIX or PROG is in operation, then control is stopped.
