Controller I/O Wiring
Minimize Electrical Noise
Because of the variety of applications and environments where controllers are
installed and operating, it is impossible to ensure that all environmental noise
will be removed by input filters. To help reduce the effects of environmental
noise, install the MicroLogix 1200 system in a properly rated (NEMA)
enclosure. Make sure that the MicroLogix 1200 system is properly grounded.
A system may malfunction due to a change in the operating environment after
a period of time. We recommend periodically checking system operation,
particularly when new machinery or other noise sources are installed near the
Micrologix 1200 system.
