Magnet Switch and LED Status Indicator
The Echo
®
Wireless Vibration Sensor has a magnetic switch located inside the sensor
that is used to activate and deactivate the sensor. Hold a strong magnet next to the sensor
housing at the location indicated on the housing, see figure below, to operate the switch.
The blue LED light should begin blinking quickly within about 4 seconds. When it starts
blinking, remove the magnet from the sensor. If the sensor was previously deactivated, it
will become active and immediately take a measurement. If the sensor was previously
active, it will deactivate and no longer take measurements. The blue LED light allows
the user to quickly determine the status of the unit by the time interval between blinks.
An active sensor will blink every 4 seconds while a deactivated sensor will blink every 8
seconds. Note: If the LED does not blink after holding the magnet next to the housing for
5 seconds, remove the magnet and try again.
