2.4 Dangers in handling the product

The traction sheave and handwinding wheel of the TW63B are designed without
safety covers. This means that the drive may only be operated in a closed room.
It must be ensured when persons are in the vicinity of the machine that there is
adequate safety clearance to all revolving parts (marked in yellow).

With the vertical version, do not place any objects (e.g. tools etc.) on the
handwinding wheel, as there is a risk of injury as a result of parts being thrown.

In the event of improper use, there is a risk of personal injury or to the life of the
user or third parties, or impairment on the subassembly or other assets can
arise. Malfunctions that can impair safety must be rectified immediately.

When working on the drive, it must be de-energised before work is started, and
the system must be secured against inadvertent switching on.

A sign indicating that maintenance work is under way on the drive must be
attached in the area of the main switch.

Emergency brake, NBS : if an emergency brake NBS is fitted, the sequence and
procedure for emergency rescue change. This also applies to testing and setting
up procedures. Follow the instructions in the separately supplied operating
manual.

The shaft version of the machine (MRL) usually has no manual release (possible
as an option). It can only be operated with suitable electrical additional measures
that are not included in the scope of supply.

Suitable measures must be taken by the manufacturer of the elevator
installation:

to be able to operate the brake in emergencies (power failure).

to enable release of the car from the engaged position if the safety gear is
triggered. (For example, by means of a winching device for ropes on the elevator
car or counterweight.)

to be able to carry out an individual check of the two brake circuits.

It must be ensured that a fault generated by the encoder, the brake or the brake
activation is detected by the elevator control or frequency inverter. The control
system must immediately place the elevator in a safe state.

The elevator system must be fitted with a safety device complying with EN81 or
that detects unintended elevator car movement with the door opened and
initiates suitable measures.
