Installation and Wiring Precautions
Note Do not latch the RUN output and use it in a circuit to stop a controlled object.
Chattering of the relay contacts used in the output may cause incorrect opera-
tion.
When the PLC controls an operation such as the clockwise and counterclock-
wise operation of a motor, provide an external interlock such as the one
shown below to prevent both the forward and reverse outputs from turning ON
at the same time.
This circuit prevents outputs MC1 and MC2 from both being ON at the same
time even if both CIO 000501 and CIO 000502 are both ON, so the motor is
protected even if the PLC is programmed improperly or malfunctions.
Be sure to consider the following factors when installing and wiring the PLC to
improve the reliability of the system and make the most of the PLC’s functions.
Do not install the PLC in any of the following locations.
