United States United States dedicated heat pump water level switch, 4:00 float level switch

Float switch Caution: 1: gently (because float switch inside the reed, is fragile, it is in use due note) 2: PP plastic float switches use a temperature below 80 degrees , stainless steel is 180 degrees. 3: Use low voltage power (10W) must not exceed 100VDC, current 0.5A, (high power 50W) must not exceed 220V, current 1A, if you have special requirements, to be customized. 4: Try to avoid vibration during use, magnetic fields, or prolonged beyond the maximum operating temperature. 5: Use liquid must not be too thick. 6: Please use foam packaging during transport. Float Level Switch Installation Instructions ˉˉˉˉˉˉˉˉˉˉˉˉˉˉˉˉˉˉˉˉˉˉˉˉˉˉˉˉˉ ◆ installation location should be away from the inlet, or switch due to enter fluctuations outlet and cause a malfunction. ◆ If the switching device in the container wall, the installation of the L-shaped angle bracket. ◆ If the switch means in the stirring area, install anti-wave tube or anti wave baffles. ◆ The control circuit load must match the float switch contact capacity. ◆ the proportion of liquid to be measured must be larger than float proportion. ◆ float action points have been adjusted according to the requirements of customer orders at the factory, please do not adjust the float position. Level switch contact protection circuit ˉˉˉˉˉˉˉˉˉˉˉˉˉˉˉˉˉˉˉˉˉˉˉˉˉˉˉ ◆ When the float switch for use in a motor, relay, solenoid coil, which are circuit inductive loads, it is recommended to protect the line across the load in parallel, such as: RC (buffer), varistors, diodes. Note: Do not float switch connected directly to the solenoid valve, motor or solenoid switch ◆ When the float switch is used in the capacitor, the hot light bulb, very long cable lines, and capacitive load, the switch contacts between the Swells generated a current; recommends protection float switch in parallel across the line, such as current limiting resistor or surge absorber and the like. Float level switch Common Faults and exclusion ˉˉˉˉˉˉˉˉˉˉˉˉˉˉˉˉˉˉˉˉˉˉˉˉˉˉˉˉ ◆ Symptom, Causes and Remedy float does not move ① liquid specific gravity less than the specific gravity float → float proportion of newly confirmed ② float leaks → contact the company to replace the float ③ foreign body stuck → Remove foreign ◆ float float action, but no signal output ① float position offset → adjust the position of the float the reed switch ② damage → Replace reed switch ◆ signal output is not normal, there is magnetic interference near → eliminate magnetic ◆ signal remains, can not be recovered, the float can not return, a foreign body stuck → Remove foreign
