damage, hazards or faults may result.
Intended use
The WSG-29 lift machines have been manufactured in compli-
ance with the latest state of the art and recognised safety reg-
ulations. They may only be used for the purpose for which
they are intended, and with all safety devices in proper work-
ing order.
The WSG-29 may only be used for driving lifts. "Intended use"
also requires that the instructions contained in the documen-
tation supplied with the machine and the commissioning
instructions be observed, and that the specified inspection and
maintenance work be carried out.
Warranty and liability
Our " onditions of Sale and Delivery" shall apply for all our
supplies and services.
We do not accept any warranty or liability claims for personal
injury or property damage resulting from one or more of the
following causes:
• Improper use of the lift machine
• Improper installation, commissioning, operation or mainte-
nance
• Operation of the WSG-29 with defective and/or inoperative
safety or protective devices
• Non-compliance with the instructions contained in the
operating instructions or other documentation supplied
• Unauthorised construction modifications to the WSG-29
• Insufficient monitoring of parts subject to wear
• Repairs carried out improperly
• Emergencies caused by external forces or force majeure
Safety precautions
Only qualified personnel are authorised to perform any plan-
ning, installation or maintenance work, and this must be done
in accordance with the relevant instructions.
The personnel must be trained for the job and must be familiar
with the installation, assembly, commissioning and operation
of the product.
The WSG-29 lift machines are intended for use in an enclosed,
lockable machine room to which only qualified personnel and
personnel authorised by the customer have access..
Danger
Warning
Caution
• WSG-29 lift machines are not ready-to-use products; they
may only be operated after they have been installed in lift
systems and their safe operation has been ensured by taking
the appropriate measures.
• heck the proper functioning of the motor and the brake
after installing the machine.
• Repairs may only be carried out by the manufacturer or an
authorised repair agency. Unauthorised opening and tam-
pering may result in injuries to persons and property.
• The machines are not designed for direct connection to the
three-phase system but are to be operated via an electronic
frequency inverter. Direct connection to the mains may
destroy the motor.
• High surface temperatures may occur on the external parts
of the machine. Therefore, no temperature-sensitive parts
may be in contact with these parts or attached to them.
Protection against accidental contact should be provided, if
required.
• The E type-examined fail-safe brakes provided are designed
only for a limited number of emergency braking operations.
They must not be used as working brakes.
• If the motor is not energised, no torque is produced. This
may result in uncontrolled acceleration of the lift, if the
brakes are released. Therefore, the motor winding should be
short-circuited to produce a speed-dependent braking
torque while the motor is not supplied with current. (Use
the main contacts for short-circuiting as rated motor cur-
rent may be flowing.) The motor must never be short-
circuited while it is energised.
• High voltages are applied at the terminal connections during
the operation of synchronous motors.
Note

Gearless Lift Machine
WSG-19
Operating Instructions
The compact flat-type gearless WSG-19 lift machines are
designed for gearless traction sheave lifts with machine
room. They are intended for operation with a 2:1 or 1:1
suspension and are distinguished by their high efficiency,
extremely low noise and excellent operating characteris-
tics.
The WSG-19 gearless lift machines are designed solely for
use with electronic frequency converters.
The synchronous motor has been designed for various
rated torques, based on a number of overall widths. It
can also be supplied for several rated speeds, which can
then be further adapted to meet individual customer
requirements.
The machine comprises a grey cast iron frame (11), the
three-phase motor, traction sheave (4) and shoe brake
(1).
The shaft is very sturdily designed to accommodate the
high loads acting on the traction sheave. At the D end, it
is supported in a robust self-aligning roller bearing (6).
Six threaded holes (6) are provided on the front end
periphery, permitting a mechanical return motion device
to be fitted in case of an emergency.
The stable D end shield (5) is of spheroidal cast iron. At
the ND end the shaft is also carried in a self-aligning
roller bearing (15) which is preloaded by means of a cup
spring. The bearing is incorporated in ND end shield (13)
of grey cast iron. The two bearings are sealed with inter-
nal and external shaft sealing rings.
A separately driven low-noise fan (10) is mounted on top
of the ND end shield. The terminal box is arranged on
the right-hand side (viewed facing the shaft).
The mounting flange on the ND end shield incorporates
the speed/position measuring system (16).
The brake is connected to a A - system via a control unit
which is included in the scope of supply. This over-exci-
tation rectifier can be installed, for example, in the con-
trol cabinet. The terminals for the brake monitoring con-
tacts, the motor terminals and the temperature detector
monitoring contacts are accommodated in the terminal
box.
The brake can be released manually, if required, by oper-
ating the manual release lever. The braking torque can
be adapted to the specific needs, if necessary, by adjust-
ing the two brake springs.
No brake lining wear occurs, since in modern drive equip-
ment such brakes are under friction only in an emer-
gency. Normally they are only applied when the machine
is at rest.

5. Transport and storage
The lift machines leave the factory in perfect condition
after being tested.
Make a visual check for any external damage immediate-
ly upon their arrival on site. If any damage incurred in
transit is found, make a notice of claim in the presence
of the carrier. If necessary, do not put these machines
into operation.
Transport
Observe the relevant safety regulations and
take the centre of gravity into account
when handling the lift machines.
The motor has to be hung up at the 4 carrying rings that
way, that the load angle ais always £45° between the
ropes.
The eyebolts are designed for the specified machine
weight, i.e. it is not permitted to suspend additional
loads.
Storage
Store the motors only in closed, dry, dust-free, well-ven-
tilated and vibration-free rooms (storage temperature:
-20° to 60° ). Do not store lift machines in the open air.
Bright parts are not sufficiently preserved to withstand
extended periods of exposure.
Avoid excessive storage periods (recommendation: max.
one year).
After prolonged storage (>3months), rotate the motor in
both directions at a low speed (< 20min-1) to allow the
grease to distribute evenly in the bearings.
Measure the insulation resistance before initial operation
of the machine. If the value has dropped below < 1kW
per volt of rated voltage, the winding needs to be dried
(insulation meter voltage: 1,000V D ).
Unpacking
Dispose of the packaging material in an
environmentally friendly manner or reuse
it.
Any special transport aids or shipping
braces are left with the customer.
Warning
Note
This can be done, for instance, with heated air, in a dry-
ing oven, or by applying a d.c.voltage to the motor con-
nections.
Make sure that the voltage selected does not exceed the
values shown in the figure
"Drying the winding" . Let the
temperature rise to about 70 – 80° and maintain it for
several hours.

Operating Instructions
Be sure to check the base frame or founda-
tion loads by calculation before installing
the lift machine.
The lift machine may only be installed if the relevant
safety precautions have been met. The machines can be
used in lift systems with a machine room.
The machines may only be installed, electrically connect-
ed and put into operation by trained specialist personnel.
The system-specific conditions and the requirements of
the system manufacturer or plant constructor must be
met.
over the machine and especially the
brakes when doing any machining or dust-
producing work in the shaft or machine
room.
The measuring system is only accessible
from the rear side. Therefore, leave enough
space between the wall and the rear side of
the machine or ensure that the machine
can be moved away from the wall.
Degree of protection
The lift motors are designed with degree of protection
IP23 M / IP125, i.e. M : during operation
S: at rest.
The traction sheaves are provided with holes for the
cooling air circuit and with external fins for stiffening.
Therefore, take special care.
When making the electrical installation, make sure the
cable connections to the terminal boxes are sealed tight-
ly.
Ambient conditions
The following ambient conditions must be ensured on
site:
Altitude: max. 1,000m a.s.l.
Ambient temperature: - 5... 40°
Max. rel. humidity: 85% at 20° (no moisture con-
densation)
Install the machine so that ventilation is not obstructed,
i.e. sufficient heat dissipation by convection and radia-
tion must be ensured.
The torque and power values indicated in the Technical
Data apply to the above ambient temperatures and alti-
tudes. In case of a deviating altitude and/or ambient
temperature, the reduction factors k shown in the dia-
gram below must be used.
Mpermiss. = k * MN
Ppermiss. = k * PN
Fastening the machine
The rope force can be applied to the lift
machine in any direction.
The machine or base frame should be mount-
ed on rubber pads for vibration damping.
The machine is fastened using 8 bolts for:
WSG-19: M 24 - 8.8; tightening torque: 680Nm or
WSU-19: M 24 - 12.9; tightening torque: 1,150Nm.
The permissible uneveness of the mounting surface is
0.1mm. The mounting surface must be sufficiently dis-
tortion-resistant and stable to accommodate the forces
occurring in the system.
After completing the adjusting work or after a
breakdown, tighten all the fastening bolts of
the machine, using the specified torque.
No welding work may be performed on the
lift machine, nor is it permissible to use the
machine as a mass point for welding work.
This could destroy the bearings and the
magnets.
Lift machines are generally equipped with rope slip-off
guards. After putting the ropes in place, adjust them so
that the distance between the rope and the rope slip-off
guard does not exceed 1.5mm.
If the machine is not installed in the machine room "on top"
of the shaft, the installation of the rope slip-off guards may
have to be modified. In this case, optional rope slip-off
guards are available that can be fitted to the foot area of the
machine.

Operating Instructions
7.1. General
The electrical connection may only be made
by a qualified electrician.
Before starting any work on the machines,
ensure that the lift machine or system is
properly isolated.
Before making any connections check that
•the connecting cables are suitable for their specific
application and for the relevant voltages and currents.
•the sufficiently dimensioned connecting cables and
torsion, strain and shear relief as well as anti-kink pro-
tection are provided
•the protective conductor (Protection lass I only) is
connected to the earthing terminal
•there are no foreign bodies, dirt or moisture in the ter-
minal boxes
•cable entries not in use and the terminal box itself are
tightly sealed to prevent the ingress of dust or splash
water.
The insulation system of the motors is
designed such that they can be connected
to a converter with a maximum d.c. link
voltage Ulink max up to max. 700 Volt.
Note: Ulink max is the maximum value of the
d.c. link voltage which is only transient and
approximately equivalent to the inception
voltage of the braking chopper or of the
energy recovery unit.
The maximum permissible rate of voltage
rise (dU/dt) at the motor terminals may be
max. 4 kV/ms.
The overvoltage at the motor terminals
must not exceed 1.56 kV. It may be neces-
sary to use motor current filters or reactors
to achieve these values.
7.2. Motor connection / Winding protection
The electrical connection of the motor and the winding
monitoring devices is made in the terminal box on top of
the machine.
The motor cable must be shielded. Ensure that the cable
shield contacts the frame over a large area at both ends.
The motor phases U1, V1 and W1 must be connected cor-
rectly to the corresponding phases of the converter; they
must not be interchanged.
The thermocouples installed in the winding
such as PT thermistor detectors and ther-
mostatic switches must be evaluated in the
control system or frequency converter to
protect the motor from overtemperature.
The separately driven fan must be properly
connected and operated. It can be switched
in dependence of temperature by the ther-
mal switch S4, if required (relay must be
used).

7.3. Speed/Position measuring system
The basic version of the lift machines is equipped with a
E N 1313 sine-cosine encoder from Heidenhain GmbH.
The encoder is connected via a 17-pole signal plug con-
nector which is fitted to the measuring system housing.
Alternatively, the machines can be equipped with the
encoder types ERN1387 also from Heidenhain GmbH.
These measuring systems are connected via a 17-pole
signal coupling fitted to the motor.
We can also provide other measuring systems on request.
We recommend the use of an appropriate
cable set to connect the measuring system
to the converter system. able sets can be
supplied as accessories.
The measuring system of the WSG-19 lift
machines is matched to the associated con-
verter. Do not change the adjustment as
this may make it impossible to use the
motor.
On the measuring system housing there is a
label showing the "offset angle" deter-
mined at the factory.
Note: This value depends on the converter.

Earthing
For safety reasons, it is very important that the motor be
properly and carefully earthed.
It is essential to use the earthing terminal
in the terminal box. In addition, an earth-
ing screw is provided on the motor frame
for the connection of a protective or earth-
ing conductor as specified in VDE 0100 and
VDE 0141 respectively.
When using shielded power cables, make sure the cable
shield metal contacts the motor frame over a large area.
This is achieved, for example, by special cable glands pro-
vided for shield contact.

machines, type WSG, can be short-circuit-
ed, if required, to brake the lift machine
faster. This is, however, only permissible at
speeds less than the rated speed of the
respective motor.

7.4. Brake
The brake magnets are supplied with d.c. voltage by the
overexcitation rectifier, which is supplied separately. The
rectifier should be installed in the control cabinet of the
lift system.
The logic output of a PL (24 V control voltage) can be
used for controlling the brake.
If the control voltage [15..35 V(D )] is applied, the mag-
net is excited (provided the supply voltage is applied) and
the brake released.
The overexcitation time and the holding
voltage are factory-set for the specific
machine. Do not change the holding volt-
age and the overexcitation time as this can
destroy the brake magnet through over-
heating.
This digital PL input could be deactivated
if needed. Please contact the manufacturer
in this case.
To reduce the switch-off time, switching
can be effected from the d.c. side. (refer
„ ircuitry suggestion for brake control“ )
Repeated switching of the brake magnets
during the overexcitation period must be
avoided as this will result in overloading of
the brake control unit. Therefore, a mini-
mum brake operating time of approx. 1.5 –
2s should be maintained during an
inspection or commissioning drive.
The control, input and output cables have
to be installed separately.
Note on the use of d.c./a.c. side switching:
A.c. side switching is recommended for nor-
mal operation, since the lift machine is
then decelerated in a controlled manner to
zero speed and the switching noise of the
brake is negligible.
When braking in the event of a breakdown (emergency
stop) or during an inspection drive, the switching should
be performed from the d.c. side, since this ensures a
faster braking effect with the car being stopped earlier.
It is therefore recommended to use 2 separate contactors
for the brake control circuitry, one of which switching at
the d.c. side, the other one at the a.c. side.

9.3. Lubricating instructions
Relubricate the main bearing after about 7,000 hours of
operation, using a KP 2 N-30 to DIN 51 502 grease such
as Wälalit LZ2 or Klüberlub BE 41-542 (approx. 58g on
DE and approx. 16g on NDE).
Use a conventional grease gun and press the grease into
the hydraulic-type grease nipples to DIN71 412 AM 10x1.
The relubricating points are provided on the D and ND
end shields of the machine. The DE grease nipple is
located behind the traction sheave. Turn the traction
sheave until one vent hole coincides with the grease nip-
ple, and the nipple is thus accessible.

9.6. Emergency evacuation
The lift design engineer must always pro-
vide for an electric return motion control
or for a manual rewinder (please note EN
81-1 /12.5.2)
Should a failure occur with the car at rest, the car can be
moved with the drive connected to the mains or to an
uninterruptible power supply (UPS) or mechanically
under its own load with the emergency brakes temporar-
ily released.
These brakes are released electrically either from the
mains or using a UPS. They can, however, also be released
manually.
The manual releasing of the shoe brake can be performed
by using the release lever.
If the brakes are released with the motor deenergised,
the motor windings should be short-circuited. This pre-
vents the lift from accelerating in an
uncontrolled manner since the short-
circuiting produces a speed-dependent
braking torque.
A mechanical return motion device can
be fitted at the operator's own respon-
sibility if the lift needs to be moved
manually in case of a breakdown or if
the car is caught by a safety device.
The use of the return motion device is
shown in the drawing.
Bolt the bearing block to
a cross-beam at the rec-
ommended spacing. The
cross-beam is firmly con-
nected to the lift
machine. When fitting
the device, a switching
command "electrical sup-
ply disconnected" must be
activated.
The specific conditions resulting from
the different traction sheave types and
brake arrangements must be taken into
account in regard to the arrangement
of the return motion device.
Then screw the threaded bolt into an
appropriately positioned threaded hole
in the traction sheave using a spanner.
While releasing the brake magnets, either electrically or
using the brake lever plates, the slide block can be dis-
placed by turning the corresponding nuts. This turns the
traction sheave. The bolt can then be moved to a new
hole in the traction sheave, if required.
The lift must be braked when changing the
bolt.

9.7. Testing the brake system to EN 81-1
The brake system should be tested with the
car about halfway down the shaft. If any
motor short-circuit connections have been
made, these should be deactivated so that
the brake effect can be tested indepen-
dently.
Overload
The brake system should be tested by interrupting the
power supply to the motor and brake system with the car
moving downward at rated speed and 1.25 times the
rated load. The brake system must be capable of deceler-
ating the car.
Failure of a brake
If one brake fails, the brake system must still be capable
of decelerating the car sufficiently during its downward
travel at rated load and rated speed.
When simulating the failure of one brake, the other
brakes must be kept open separately, even if the safety
circuit is open. This should preferably be done using suit-
able electric circuitry, but can also be performed manual-
ly.
This state must not be maintained in the long term.
Observe the lift during this test. If it does
not decelerate, close the open brake circuit
immediately.
Separate operation of the individual brakes
There are several possible ways of operating the brakes
separately:
•The preferred method is separate electrical control of
the brakes. The individual brakes can be activated/deac-
tivated quickly by individual control buttons (The con-
nections for the two coils are accessible in the brake
magnet.).
•Block one brake arm in its open position by using a
suitable excentric lever. This lever makes it possible to
release the blocked brake arm immediately in the case
of an emergency.
Note
Note
Monitoring the brakes
heck the brake monitoring switches individually. No car
travel must be permitted if a micro switch signal is miss-
ing or a wrong signal operates.

Example:
Lift machine WSG-19.4
Rated motor torque MN= 2500 Nm
Braking torque of one half Mb= 1.25 x 2500 Nm (125%)
a = 165 - (3200 / 68) = 118mm
•Slacken locknut (30) and turn pull rod (14) until
dimension "a" of the compression spring corresponds
with the required braking torque MBof one side as
specified on the label. The label is on the brake lever
directly under the compression spring.
•Secure pull rod (14) with locknut (30).

9.8. Brake
Replacing the brake shoe
Replace the brake linings when they are
worn down to a thickness of less than 3-
4mm or no longer usable.
Before working on the brake secure the
counterweight and the car against any
uncontrolled movement. Disconnect the
motor and the lift system from the mains
supply. No torque may act on the traction
sheave.
•Slacken locknut (30) and screw out pull rod (14). au-
tion! The brake shoe lever will tilt outwards.
•Remove shaft circlip (6) from bolt (5). Remove the bolt
and take off the shoe.
•Slacken locknut (9) and unscrew bolt (10) through
some turns.
•Regrease the sleeve bearing bushes, insert new brake
shoe (4), install bolt (5) and the new shaft circlip (6).
•Tilt brake shoe lever (1) back and install spring (13),
spring plate (12) and pull rod (14).
•Adjust the brake torque. Secure the setting with lock-
nut (30).
•Adjust the remaining play of the magnet to
x=2.6+0.5/-0.8 mm and secure the setting.
•Bed-in the linings.
Adjusting the braking torque
The loaded spring length "a" is used to estimate the brak-
ing torque.
The total braking torque is Mbtotal = 2 x Mb
Mb: braking torque of one half of the twin brake
(recommended setting 125% of the rated motor
torque)
Distance “a” for the braking torque is calculated accor-
ding to the following formula:
