Controller I/O Wiring Minimizing 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 (i.e. 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.
