How to adjust the alarm contact position of the Sol level switch 221A-B1C-B-A1-T6
Adjusting the alarm contact positions of the Solenoid Level Switch 221A-B1C-B-A1-T6 usually requires following the specific installation and operation manuals. The general steps may include turning off the power, opening the switch’s housing, and then adjusting the position of the contacts according to the actual situation. It is recommended to follow the specific operating instructions included with the product, or contact the technical support for that product for detailed assistance. .
I’ve never seen the actual device; I searched online and guessed that liquid must flow inside the stainless steel part. There is a magnetic float inside, which rises to the position of the contacts; the magnetic force causes the reed switch to close, and then the signal is amplified, prompting the limit switch represented by the black square in the image to activate, thereby generating a signal. By changing the position of the contact within the stainless steel tube, it is possible to adjust the liquid level at which the alarm is triggered.
