2.9 Input Protection
The MicroMux is equipped with lightning protection components on the control signals. As a result, care
must be exercised in the installation to maximize their effectiveness. Specifically, an effective earth
ground must be attached to the MicroMux shield (S) for proper protection. Most Vibrating wire instruments
also have lightning protection components.
The Enable and Clock inputs can be connected to 12 volts directly without damaging the MicroMux. The
connections to the datalogger should be disconnected and insulated from contacting other electrical
connections. The 12V tolerant inputs allow the MicroMux to be field tested without the need for a
datalogger connection. The enable can be wired to the 12V input while the clock input can be touched to
12V. This action will cause the MicroMux to step channels for each touch to 12 volts.
