1.4 Safety

Refer also to KONE U.S. Safety Policy (SAFETY-01-003) and Elevator Industry Field Employees’

Safety Handbook.

Safety precautions Note

You should develop and follow procedures that

have assimilated the requirements of national lift

codes and other safety related regulations.

In case of conflict between the Code and the

present instructions, a full risk assessment

should be carried out and an appropriate

course of action defined with the local

regulator and company management.

The local safety codes and rules must be obeyed

whenever possible. Refer to your local procedures to take the elevator

out of use.

Follow the safe working methods defined herein.

In case you are uncertain of the method’s safety,

seek expert advice.

Follow this instruction. Do not skip any step within

the procedures; otherwise there may be a

potentially dangerous situation which you have not

considered.

Warning signs highlight possible hazards.

Be sure that you have the latest maintenance

instruction in use. If you are unsure please

contact KONE.

ENSURE THAT ELECTRICAL EQUIPMENT AND

CONDUCTORS ARE SAFELY DE-ENERGISED

BEFORE WORKING ON THEM.

A locking off system for main electric supply isolator

or other system (for example fuse removal, locking

and tagging system, etc. when applicable) must be

agreed with person responsible for the building

electrification.

Do not connect or disconnect any connectors

when the power is ON.

Personal safety equipment must be available and

used as required.

Handle and dispose of waste materials in

accordance with company procedures that have

assimilated the regulations applicable to your

country/state.

Ensure that your work does not cause a hazard to

others. In particular keep access ways and fire exits

clear.

8.6.4.13.2: Kinetic Energy and Closing Force for Automatic Doors (Horizontal)

Procedure Note

Kinetic Energy for Automatic Doors (Horizontal)

To test the kinetic energy:

•Check the time the leading edge of the door

takes to travel the code zone during closing.

•Verify that the average door closing time for the

doors is greater or equal to the minimum door

closing time shown on the door operator data tag.

•The code zone for side opening doors is

measured at 2 in (50mm) from fully

opened to 2 in (50mm) from fully closed

positions.

•The code zone for center opening doors

is measured at 1 in (25mm) from fully

opened to 1 in (25mm) from fully closed

positions.

•Adjust the doors, as required.

Closing Force for Automatic Doors (Horizontal)

•Park the car at floor level and start the doors in

the closing direction. Allow the doors to start

moving in the closing direction to about midway

of their normal travel and stop them.

•Push a force measuring device designed for that

purpose (KONE US45371) against the leading

edge of the door, removing the stop so the door

is held stationary by the gauge.

•Back the gauge off until the door is barely held

stationary by the gauge and read the value. The

closing force may not exceed 30lbf (135N).

Adjust the closing force, as required.

MX10 & MX20 Brake Maintenance

MX10 MX20

General Maintenance Information for MX10 and MX20 Brakes

•MX10 and MX20 machines are equipped with two independent direct acting brakes. The

brakes must always be adjusted separately.

•The center nut must be checked during routine maintenance and prior to any brake adjustment

to verify the washer is loose under the center nut when the brake is set. As the brake shoe

wears, the center nut moves in with the brake shoe and can bottom against the brake body,

preventing the brake from setting fully. Loosen the center nut as needed until the washer under

the nut turns freely.

•There are four adjusting screws per brake. The adjusting screws are held in place by locking

plates. The locking plates must always be in place during elevator operation to prevent the

adjusting screws from changing.

•Adjusting the brake is a four-corner procedure. Any adjustment must be made evenly on the

four screws. Turning one screw significantly more than the others will cause the brake to bind

internally and the brake will not pick consistently.

•The adjusting screws are very sensitive. A ¼ turn corresponds to a .010 in. [.25 mm] change in

air gap.

•For MX10 and MX20, the emergency brake is the brake closest to the motor junction box. The

emergency brake will be marked with an identifying label.

•Always put elevator on cartop inspection for MX10 and MX20 applications
