EWD-H-XJ4 Elevator Load Weighing Device

INTRODTION MANUAL

• This system is applicable to all elevators with movable platform car (containing 4-channel programmable switch signals)
• Main characters:

• 1.Contactless inductive working mode, solid state relay output, no need to fix the original position of elevator overload switch, and to change structure of elevator platform car.
• 2.Electrical properties is in compliance with the standard of the International Electro-technical Commission.
• 3.Set up all parameters on the spot.
• 4.Adopt strong inductive magnet, improve the anti-interference ability to the utmost.
• 5.System carry scientifical computing out according to mathematical equations to automatically amend detention of error. It also has no-load auto zero capacity
• 6.It is totally convenient to adjust on the pot by means of artificial self-study or artificial displacement.
• 7.Control method of programmable output signal created by ourself is applicable to all kinds of traction elevator with movable platform car.
• 8.Integrated structure design: small size, easy installation.
