UFKS-2 water supply and drainage controller is a kind of liquid level controller which uses magnetic levitation ball to control two-point switch signals. Reed switches are installed at different heights of the conduit. When the magnetic floating ball floats up and down with the change of liquid level, the magnetic steel in the floating ball makes the electric shock of the reed switch at the corresponding position attract or disconnect, and sends out the switch signal. The AK level control panel is installed in the junction box, which can directly drive the level and automatically start and stop the water pump. Control modes are divided into water supply (lower limit pump start and upper limit pump stop) and water drainage (upper limit pump start and lower limit pump stop), which can be set by users themselves.
Basic parameter
Measuring range l: ≤ 6000mm Medium temperature: ≤ 100℃
Action error: 2mm? Release error: 2mm
Specific gravity of medium: ≥ 0.8 (users suggest otherwise when it is less than 0.8)? Connecting flange: DN50? HG20593-97 (RF)
Pressure grade: 0.6-2.5Mpa Power supply voltage: 24VDC.
Contact output: 220Vac 5A can also directly drive CJX2-09 AC contactor.
Show? Instructions: start the pump: blue LED indicator lights up, stop the pump: red LED indicator lights up.
Control mode: select water supply (the lower limit pump starts and the upper limit pump stops) and water drainage (the upper limit pump starts and the lower limit pump stops) through the button switch.
Working environment: ambient temperature -25 ~ 85℃, ambient humidity 5% ~ 95%, mechanical vibration 10 ~ 150 Hz.
Transmission distance: less than 100 meters.
Precautions:
The turn-on frequency of the upper and lower reed switches shall not exceed 3 times/minute.
Rain and high temperature should be avoided as much as possible on site.
For the control that needs manual/automatic switching and button switch, it can be extended through the electrical control panel.
For high-power water pump motor, it should be used together with other contactors and their supporting electricity.
Connection:
Output: Two-wire terminals are connected to 220V contactor.
Power supply: two-wire terminal 24VDC red+,black-.
