Any that is outside of the range set in the parameters of (lower limit) and (upper limit) of the third block cannot be set. (See page 5) Related parameters: (page 54) (page 54) [Setting example] Changing the from 25 C 1195 C Press the or keys display. will be registered in the () in three seconds. After that, the controller will operate with the being

15 Manual mode setting (Settings: off/on) This parameter switches the control mode between Au and Manual. During Manual operation, the decimal point is kept on at the far right in the display section. During Manual operation, au tuning or self tuning is not done. If the mode is switched Manual while au or self tuning is being done, the tuning is forcibly terminated. The PID parameter remains the same in such cases. Manual operation output is not limited by MV limit. Manual operation can be carried out during standby operation. The operation output set value during Au/Manual operation mode and manual mode is sred in non-volatile memory. It is kept sred even if a power interruption occurs. When the power is turned on again, the state before the power interruption is resumed. The following table lists the operation output at the time of switching between Au and Manual.. Au Manual Manual Au Balanceless bumpless MV output according (Switches manual mode, PID operation holding the MV value just (Sudden change may occur before the switching.) the MV value.) Manual MV Manual Single output Manual PID calculation AUTO MAnU = ON P-n1 = Single Dual output MV1 MV2 Au Au Limit Limit Standby Standby Error output Error output OUT1 OUT2 Manual [Setting example] Switching manual mode Press and hold the SEL key for one second, and is displayed. Press the SEL key once, and the current set value ( ) on the display section starts flickering. Press the or the keys display. Press the SEL key once, and the manual lamp at the lower right corner comes on, indicating that the mode has been switched Manual. To display operation status, press and hold the SEL key for two seconds. 15

16 Standby setting (Settings: off/on) This parameter switches the control between RUN and Standby. During standby, the control output and the alarm output stay OFF, like the standby for ramp-soak operation. While the alarm with a hold is selected, the hold function takes effect after changing the Standby setting from ON OFF. is displayed during the standby for ramp-soak operations or the controller changes the standby state in case of the occurrence of errors. The other operations are the same as those of the rampsoak standby. The setting of ON/OFF for standby is saved after poweroff. When the standby is set ON during the au-tuning, self-tuning, and ramp-soak operations, those operations will sp. (The PID constant will not be renewed.) Even through it is set OFF later, the au-tuning, self-tuning, and ramp-soak operations will not be re-started. During standby, the ON-delay timer is reset. When returning RUN from the standby state, the timer will start from the beginning. [Setting example] Starting the control Press and hold the SEL key for one second. will be displayed. Then press the key once. The current setting ( ) flashes on the display. Press the or keys display. The standby state for control is selected.

Up eight pairs of rampsoak operation can be programmed. The first ramp starts at the (Measured value) that is the one just before running the program. The program can also aumatically run at power-on (Power-on starting function). Refer the parameter of (page 47).
