Cable Float Level Switch Instruction Manual

I. Overview:

Cable float level switch /Float switch /High sealing performance float switch. The cable float level switch /Float switch is suitable for controlling the operation of the liquid pump and adjusting the liquid level. It can also be installed in the submersible pump to control and protect the motor. High sealing performance is ensured by polypropylene injection.

Second, the scope of application:

Cable float level switch /Float switch is a switch that can adjust the level of the tank, tank or well. It can be automatically adjusted, easy to operate, easy to install, safe, reliable, maintenance-free, non-toxic and environmentally friendly. It is resistant to sewage, widely used in the family , Pools for factories, mines, oil, tanks for acid and alkali, barrels, tanks, tanks, etc.

Third, the working principle:

The cable float level controller is designed using the principle of gravity and buoyancy. It mainly consists of a float body, a large-capacity micro switch installed in the float body, a drive mechanism capable of turning the switch on and off, and a switch connected to the switch. Three-core cable. Features: Stable and reliable quality, no malfunction due to liquid level fluctuations, corrosion resistance, long service life, easy installation, affordable.

Fourth, performance characteristics

Strict manufacturing process provides a reliable guarantee for product quality. The shell is made of engineering plastics with high mechanical strength and good sealing. The cable is made of special materials, resistant to oil, acid and alkali, and has superior anti-corrosion capability. Simple structure, reliable performance. Output stable and reliable switch control signal, without any malfunction, high reliability. Easy to install, easy to debug, move the positioning block up and down , You can freely adjust the control range of the Huai River.

V. Technical parameters

Rated current/voltage: 8A/220VAC SPDT.

Material: Polypropylene

Operating temperature: -10Celsius ~ 80 (plastic) degrees Celsius.

control precision: ±0.05m.

Applicable medium: Clean water, sewage, oil and acid-alkali liquid below the low concentration.

cable length: 2m/3m/5m/10m/15m.

Sixth, instrument wiring and installation methods

1KW and 1KW The following single-phase pump can directly connect the floating switch in the circuit. 1KW Above the pump, the floating switch can be connected in series in the control circuit of the electric control box. The control height of the liquid level is determined by the length of the cable in the liquid and the position of the weight on the cable. Use brown and black wires: When the float is in the lower level, the contact is on. When the float floats on the liquid level, the contact is in an unblocked state. Use brown and blue wires: When the float is in the upper level, the contact is in the ON state. When the float is in the lower level, the contact is in a disconnected state. Unused wires must (be absolutely insulated.) ) Float level controller recommended voltage24V.

Seventh, heavy hammer device method

1After inserting the cable switch of the float switch through the concave hole in the center of the weight, gently push the weight so that the plastic ring embedded in the round hole will come off due to the thrust of the cable head. (If necessary, also This plastic ring can be removed with a screwdriver.) Put the dropped plastic ring on the cable and you want to fix the weight to set the fluid position.

2, Gently push the hammer to pull out the cable until the center of the hammer hits the plastic ring. The light weight will not slide off as long as it is on the plastic ring.
