*1: When there is a probability that two or more switches are pressed
simultaneously, each switch must be provided with a diode.
(Refer to the right figure.)
*2: A fuse-blown error will also be displayed when the external
supply power switches off.
*3: The fuse in the output unit is provided to prevent the external wiring from
burning out if the outputs of the unit are shorted.
Therefore, it may not protect the output elements.
The fuse may not be blown if the output elements are damaged in the fault
mode other than a short circuit.
