Memory clearing when the Windows® version of the tool is ready for online operation or
when the Ladder Chart System is not purchased yet by the user.
If neither the Windows® version of the tool nor the PCs can be placed into an online state
(due to, for instance, an "line error"), discharge all the memory backup energy and clear the
memory by performing the procedure described below. Then, restart the system.
Procedure
① Before handling the CPU module, ground yourself to discharge any static electricity.
② Turn off the power switch on the power supply module.
③ Open the front panel as shown below.
④ Insert a finger nail or the tip of a slotted screwdriver about 1 mm into the slot at the lower
right of the front cover (see the figure below). Then carefully lift away the front cover in
the direction of the arrow.
Notes
Do not insert the slotted screwdriver more than 1 mm. Otherwise the internal PC board
may be damaged.
