(2) Control output (OUT) action indicator

A green LED lights when the control output (OUT) is ON.

(3) Serial communication output indicator A yellow LED blinks while serial communication TX (sending) is output.

(4) PID auto-tuning action indicator A yellow LED blinks while PID auto-tuning is functioning.

(5) PV display

Indicates actual temperature (PV) with a Red LED.

(6) SV display

Indicates setting value (SV) with a Green LED.

(7) key

Increases numeric value on the SV display or switches the selected item.

(8) key

Decreases numeric value on the SV display or switches the selected item.

(9) key

Changes the Menu Item or enters the value for the selected Menu Item.

3. Operation

The sensor input character and temperature unit are indicated on the PV display for approx. 3

seconds after the power is turned on, and the rated scale maximum value is indicated on the SV display. (Table 3.1-1) (If the other value is set in the scaling high limit value, it is indicated on the SV display.) During this time all outputs and the LED indicators are on their OFF status. After a while control starts indicating actual temperature on the PV display and setting value on the SV display.

Setting value LOCK designation

• Locks the setting value to prevent setting errors.

The setting item to be locked is dependent on the designation.

• PID auto-tuning cannot be carried out when Lock1 or Lock2

is selected.

• (Unlock): All setting values can be changed.

(LOCK 1): None of setting values can be changed. (LOCK 2): Only main setting mode can be changed.

(LOCK 3): All setting values can be changed except Controller/Converter

function selection. However they return to their former value after power is turned off because they are not saved in the non-volatile memory. (Be sure to select LOCK 3 when using with PC-900 [SVTC attached])
