Mounting
Securely mount the sensor on a firm, stable surface, or support for reliable
operation. Mounting subject to excessive vibration or shifting could cause
intermittent operation. Once securely mounted, the sensor can be wired per
the wiring instructions in the next section.
You may need to adjust the sensor in the mounting due to the location of the
target in relation to the sensor face. The 871TM sensor offers margin
indication through the yellow status indicator. The status indicator blinks
when the target is 80% of the maximum sensing distance or farther from the
sensor face. It is recommended that you adjust the sensor to be closer to the
target.
