What to do if the Sitron CF12 AC Monitor relay does not change state?
If the Sitron Monitor relay does not change state, there could be several reasons. If the LED is off, it indicates a lack of power, so check the power supply. If the LED doesn’t change color, verify the installation (insertion length). Also, verify the calibration of the device.
Why does the Sitron CF12 AC flow switch turn on and off suddenly?
The Sitron Monitor flow switch might turn on and off suddenly due to radio frequency interference. To resolve this, use armored cable and shielded housing.
