ZRN711 cable float level switch is a control device capable of adjusting barrel, tank or well liquid level. It can automatically adjust, easy to operate, easy to install, safe and reliable maintenance exemption, non-toxic and environmentally friendly. It has water resistance widely used in pools, oil, acids and alkali tanks, barrels, tanks, irrigation and other household containers, factories and the like. If linking two controllers. a release to the water tower, another place to control the pump wells, It can be prevented due to lack of water open air pumps and pumping equipment damage; also three series with a controller, a release to the water tower, and the other let go and a place to filter water (wells) can simultaneously control, can be prevented due to lack of water open air pumps and pumping equipment damage; three controllers can be connected in series, a release to water (wells) can simultaneously control two pumps equipment (refer below).
3. Technical Data
1, the working voltage: 250V ~ 380V.
2, the operating current: 10 (8A) ~ 10 (4A).
3, the working temperature: 0 ~ 80 ℃.
4, electrical life: 1 * 100,000 times.
5. Mechanical life: 5 * 100,000 times.
6, lead length: 3m 4m 5m 10m length and other special materials can be customized
1, the use of black and blue wires
Float in the liquid, the contact is unreasonable state, the float next level, the contact is connected to the state.
2, the use of black and yellow wires
Float in the liquid, the contacts are connected to the state, the float next level, the contact is unreasonable state.
3, float level switch fixed weight of installation
Control the height of the liquid level by ZRN711 cable float level switch cable length and weight of the liquid at a location determined by the cable.
Fixed ZRN711 cable float level switch weight is:
1, the first non-plastic hammer to remove the bell end of the snap ring, which was set in place on the cable
2, and then the cable from one end of the plastic hammer bell penetration, set in the cable collar on defining the hammer position.
3. Finally, at the appropriate cable fixed outer container. The end of the cable to the control box, try to avoid using the middle connector, For when there are joints, the joints must not be immersed in liquid.
(Note: non-plastic hammer ring the bell end of the card may not be removed directly from the bell end of the cable penetration, and then wrapped in cable scrap bare plastic hammer can be stuck in place)
Float Level Switch Installation Instructions:
1, the water supply system
Use the 'black' and 'blue' wire:
When the float next level, the contact is connected to the state
Float at the water level, the contact is unreasonable state
2, the drainage system
Use the 'black' and 'brown' wire:
When the water level float state, the contact is switched on
When the float next level, the contact is unreasonable state
