5. CONFIGURING THE CM-221M

Range of Detection and Output Duration

Looking at the back of the CM-221M with the Mode pins located at the top, you will see two adjustment potentiometers. The one 
on the left can be turned clockwise to set the range of detection (2” to 8” / 5cm to 20cm), and the one on the right will set the 
duration of the output (0.5 to 20 seconds). 
If the output needs to be triggered and maintained in that state until triggered once more, then the Toggle feature can be used by 
turning the output duration adjustment potentiometer to the fully clockwise position.

Remote LED Switching

The CM-221M can also have its LED states controlled remotely. This is done by installing the supplied jumper from the parts 
bag onto the two pins on the back of the unit. Once installed the green and red LED’s can be triggered to change by bringing 
either one low (to ground). The yellow wire controls the green LED, whereas, the white wire controls the red LED. They can be 
individually turned on or off, or they can be wired to a SPDT contact to turn red on and green off, or vice versa.
