3-2. Instruction for front panel

:Measured value (PV) display (green)

(1)Displays current measured value on the mode 0 basic screen.

(2)Displays parameter type on each parameter screen.

:Set value (SV) display (orange)

(1)Displays set value on the mode 0 basic screen.

(2)Displays selected item and set value on each parameter screen.

:Monitor LED

(1)OUT (output) monitor LED (green)

For contact or SSR drive voltage output, a light turns on for output ON and turns off for output OFF.

For current or voltage output, the light intensity changes proportionally to the output altitude.

(2)AT (auto tuning) monitor LED (green)

On selection by , ON turns on AT waiting ( ENT key), flashes on AT execution.

(3)AH alarm output monitor LED (red)

Turns on for higher limit alarm output ON.

(4)AL/HB alarm output monitor LED (red)

Turns on for lower alarm output ON or heater break alarm ON.

(5)MAN (manual control output) monitor LED (green)

Flashes when control output is in manual operation.

(6)STBY (control output stop) monitor LED (green)

Turns on when the control output stop mode is selected.

(7)COM (communication) monitor LED (green)

Turns on when the remote communication mode is selected.

:Key switches

(1) (parameter) key

Press on set screen to move to next set screen.

Keep pressing three (3) seconds for function of move key between basic screen of the mode 0 screen group and direct call screen of mode 1 screen group.

(2) (down) key

Press on the set screen to flash the point of the least digit and to reduce data or back increment data.

(3) (up) key

Press on the set screen to flash the point of the least digit and to increase data of increment data.

(4)ENT (entry/registration) key

Press on the set screen of the mode 0 screen group and mode 1 screen group to fix the data changed by

the , keys and to extinguish flash of the point.

The function selecting screen, of the mode 2 screen group, registers data of the point flashing digit and simultaneously shifts a data changeable digit (the point flashing digit).

The input scaling screen, of the mode 2 screen group, registers data and shifts a parameter capable of being set (in the row in which the rightmost point is flashing).

Press the key for five seconds and it functions to change the basic screen of the mode 0 screen group to the function selecting screen of the mode 2 screen group and vice versa.

(5)MAN (manual) key

Pressing this key on the control output screen changes automatic control output to manual control output and vice versa. During manual control output, the MAN monitor LED flashes.

The MAN key does not function in the control output stop mode.
