C. Function to detach defective sections

For those abnormalities listed in the table below, defective units can be detached temporarily to use other con-trol units manually. While detached, an error detection is not carried out on these detached units.

There are 2 methods of setting for limited use.

(1) User operation

When an error code occurs, press the HELP key following the message on the operation panel and then turn thepower switch (SW2) OFF and ON. This allows you to use it temporarily until the main power switch (SW1) is OFFand ON (including an OFF/ON operation by the weekly timer) next time.

(2) DIPSW setting

Turning the main switch OFF and ON after setting the specified software DIPSW bit allows you to make a limiteduse of it until the bit setting is released next time (this requires the OFF/ON operation of the main power switch(SW1)).
