Magnetic test point
A magnetic test point is on the side of the housing (
), allowing a functional test of the
Rosemount 2130 Level Switch. By touching a magnet on the target, the output will change state for as
long as the magnet is held there.

Inspection
Visually examine the Rosemount 2130 Level Switch for damage.
If it is damaged, do not use it.
Ensure the housing cover, cable glands, and blanking plugs are fitted securely.
Fit a suitably rated blanking plug where required.
Ensure the LED flash rate is once every second or continually on.
If anything else is demonstrated, see
.
Electrical shock can result in death or serious injury.
If the level switch is installed in a high-voltage environment and a fault or installation error occurs,
high voltage may be present on the sensor leads and terminals.
Use extreme caution when making contact with the leads and terminals.
Make sure the main power to the level switch is off and the lines to any other external power source
are disconnected or not powered while wiring the level switch.
Ensure the wiring is suitable for the electrical current and the insulation is suitable for the voltage,
temperature, and environment.
External surfaces may be hot.
Care must be taken to avoid possible burns. The flange and process seal may also be hot at high
process temperatures. Allow to cool before servicing.
