Chapter 8. PROGRAM SETUP

8 - 3 General Reset

A general reset can be performed when the controller is in the READY AUTO mode in the normal display mode. If not in the normal display mode, press the DISP key to invoke it. A general reset has the following functions. Program settings such as program numbers 1 to 49 are all deleted. Parameters are reset to their factory defaults and the READY AUTO program run mode is invoked.

■General reset procedures

(1)Invoke the READY AUTO mode for both CH1 and CH2. Or set variable parameters PA01 and PA02 to 0.

(2)Press the FUNC, CLR and MESSAGE keys and you are prompted to confirm a general reset. “g.rESt ” is displayed in display panel 1.

(3)Press the ENTER key to execute the general reset and start startup operations that occur after a power up.

Press the DISP key cancels the general reset and returns the normal display mode.

In the fixed command control mode, program number, segment number and profile display go off.

•When the RAM backup fails at startup, the controller automatically prompts you to confirm a general reset – no key input is required - and “g.rESt ” flashes in display panel 1.

Press the ENTER key to execute the general reset. All other keys are invalid.

•A general reset does not return the following settings to factory default values.

C01, C02, C11, C12, C21 C22: these values are stored.

Note, however, that a general reset resulting from a RAM failure at startup resets also these settings to factory default values.
