What to do if my Rosemount Switch 2120 does not switch?
If your Rosemount 2120 Switch isn't switching, begin by checking the power supply. If you have a direct load switching electronics model, verify the load. Also, you may need to replace the 2120, or carefully clean the fork. If the LED is on, wait 5 seconds as this could be normal.
Why is my Rosemount Switch 2120 switching faulty?
Faulty switching of your Rosemount 2120 Switch can be due to several factors. If turbulence is the cause, try setting a longer switching time delay. If excessive electrical noise is the problem, suppress the source of the interference. Also, ensure that the cassette is the one originally supplied with your Rosemount 2120; if it's from another unit, fit the factory-supplied cassette and then calibrate.
