2Safety instructions for OMS elevator drives
2.1 Intended use
OMS elevator machines EC 2-25 Lift are designed and intended exclusively for installation and
use in electrically operated traction sheave elevators for the conveyance of persons or goods in
accordance with EN 81-1.
Use for any other purpose that the intended use as specified above is considered improper use.
OMS ANTRIEBSTECHNIK disclaims all liability for any damage or injury resulting from such im-
proper use or from errors of procedure or method.
All planning, installation and maintenance work must without exception be carried out by
qualified specialist personnel.
Qualified personnel is defined as persons who due to their education and training, special
training, instruction and experience as well as their knowledge of all pertinent norms and
standards and general and statutory specifications, requirements and regulations, accident
prevention regulations and operating conditions as authorised by those responsible for the
safety of the system to carry out the necessary work and thereby recognise and avoid potential
hazards. (Qualified personnel as defined in IEC 364).
This OMS elevator drive falls within the scope of application of the 9
th
Directive of the Ma-
chine and Product Safety Law (9. Verordnung zum Geräte- und Produktsicherheitsgesetz) and
the Machinery Directive 2006 42 EC and is a machine part to be subsequently installed for its
intended use in an elevator system and is thus without the CE mark.
Commissioning is prohibited until the installer (see Machine Directive 95 16 EC) has properly
installed the product in the designated elevator system and the CE mark has been affixed to
the elevator system to show that the safety requirements for the product as supplied by the
manufacturer are fulfilled.
All other applicable or pertinent regulations and legal requirements (e.g. on operation, mainte-
nance and inspection) remain in force.
OMS does not accept any responsibility, liability or warranty whatsoever for any damage what-
soever caused by improper, unprofessional or other actions which do not comply with these in-
stallation and maintenance instructions and or do not comply with the aforementioned norms
and standards and are thus detrimental to the product properties and characteristics.
The motors are designed exclusively for use with frequency converters. Customer supplied fre-
quency converters must be adjusted in accordance with the appropriate instruction sheets to
comply with OMS elevator machine characteristics, properties and requirements. Adjust the
frequency converter parameters to the motor output of the drive.
The drive is designed exclusively for use within an enclosed area (e.g. elevator shaft or machine
room).

The storage, installation and or operation areas for OMS drives must be closed and dry. The fi-
nal customer and the user must ensure that appropriate protective measures are implemented
to avoid any contamination whatsoever due to any building dust or dirt.
When running, the machine may only be stopped via the frequency converter and machine
brake.
OMS elevator machines may only be operated when in technically perfect condition and when
within the parameters as specified by OMS.
Intended use also includes:
•Compliance with the operating instructions
•Compliance with the statutory accident prevention and environmental regulations
•Compliance with and adherence to the elevator documentation elevator regulations and
specifications.
2.2 Im ro er use
OMS drives may not be operated in potentially explosive environments or corrosive atmos-
pheres.
The shoe brake with double circuit double acting expansion solenoid is designed for only a lim-
ited number of emergency stops. Using it as a working brake is deemed improper use.
Exceeding the permissible limits for use constitutes improper use.
Permissible limits:
•Max. motor speed: see technical documentation;
•Max. static load on the traction sheave, see technical documentation;
•Max. number of journeys hour = 240;
•Ambient temperatures during operation min.: 5° C, max.: 40° C;

Important:
•All work connected with the transport, electrical connections, commissioning
and maintenance and servicing of the drive must only be carried out by quali-
fied specialist personnel. Improper actions can cause serious injuries and equip-
ment damage.
Caution! Important note on elevator machine EC 2-25 Lift:
•The high efficiency of the elevator machine means the self-locking capacity is
negligible, i.e. the drive will start to move immediately as soon as the brake is
released.
•When installing the safety catching device, the brake system must be fully functional and
guarantee that the service brake is ready to be applied immediately at any times.
•Elevator machine operation without a fully functional safety catching device is prohibited.
The operator has sole liability for all and any injuries and damage.
•Recurring checks and tests may not lead to excessive wear, stresses or strains which could
impair the operational safety of the elevator.
Periodic tests can be done with test weights and nominal speed
Alternatively the tests can be done with an empty car and nominal speed ( up to v = 2ms
-1
).
•Releasing the elevator car from the safety catching device may only be done by moving the
elevator car in the opposite direction to the direction that caused the safety catching device
to activate. Under all operating conditions, the elevator drive may only be operated with the
max. permissible loads as specified by the elevator specifications. All and any procedures and
applications causing additional static and dynamic loads (torque, force, vibration etc.) on the
elevator drive e.g. on the traction sheave, motor, brake, housing, are prohibited. OMS refuses
all and any warranty and or liability claims if this is not complied with, irrespective of legal
basis.
•Ensure the motor does not rest on or against the mounting frame. Take appropriate measures
to ensure the above and check that this is done in each and every case. Record these
measures in a protocol as documentary proof.

2.3 Warranty and liability for the drive
•The manufacturer of the drive only guarantees proper and safe functionality of the drive if
the specifications provided with each drive are observed and if proper assembly (installation)
maintenance, testing and operation of the drive is in accordance with the maintenance in-
structions and the procedures stipulated here.
•The warranty is void if the permissible limits are exceeded during operation, maintenance or
testing.
•The customer is responsible and liable for the proper assembly (installation), maintenance,
testing and operation of the drive and must furnish proof that only trained and qualified
specialist personnel are employed.
•Should errors, defects or non-conformances be detected on the elevator system including the
drive, the system must be disabled immediately, otherwise the operator is solely liable for all
and any injuries to persons or damage to equipment irrespective of legal basis.
•Incorrect installation and or improper operation of the system, in particular with respect to
the aforementioned improper procedures or changes or modifications made to the drive or
its components irrespective of legal basis always lead to the complete and absolute non-
liability of the drive manufacturer and the invalidity of the guarantee and warranty.
•OMS refuses all and any warranty and or liability claims when the installer, operator and or
maintenance company does not furnish complete and continuous documentary proof that
the described permissible system and procedures and uses for the elevator system including
drive have been complied with (e.g. elevator book etc.).
2.4 Hazards associated with the elevator drive
The elevator drives are state of the art and are safe to operate at delivery. Any changes or
modifications, in particular when detrimental to operational safety, are prohibited.
The traction sheave and the handwheel of the elevator machine EC 2-25 Lift provided by OMS
do not have safety covers and may only be used in a locked machine room. When persons are
in the machine room, ensure adequate safety distance is kept to all moving and rotating parts
(marked in yellow).

3.1 Installation
Prior to installation, the intended frame or foundation upon which the elevator machines are
to be installed must always have been calculated and proved adequate.
The frame must be rigid enough to withstand all and any bending and torsional forces that
may occur during operation.
3.1.1 Installation instructions
For installation in position B1, observe the following:
Rope running direction downwards:
Observe the following for this installation variant:
The housing has 5 contact areas.
Ensure that all 5 contact areas lie evenly. None of the contact areas 1-5 may have an air gap
(max. permissible air gap between surface and contact area: 0.05mm).
Non-compliance can cause distortion of and damage to the elevator machine.
Rope running direction horizontal:
When the rope running direction is horizontal, the gear unit must be additionally horizontally
supported using surfaces A-D.
The same as above applies to horizontal support; none of the contact areas A-D may have an air
gap (max. permissible air gap between contact area and support: 0.05mm).

Note:
The gear unit is sealed oil-tight for transportation. With the screw plug or cap in place, the
gear cannot vent air. Starting operation with the screw plug still in place can lead to overpres-
sure in the housing and thus cause leakage and oil discharge at the shaft sealing rings.
The oil dipstick does not seal the gear.
Electrical connections
Only trained and qualified personnel may open the terminal box on the motor,
connect the electrical supply and carry out maintenance and repair work on
electrical parts of the elevator machine.
Disconnect the main switch beforehand and secure it against being inadvertent-
ly switched on!
In accordance with DIN - EN 81 – 1, the safely rules governing the construction and erection
of elevator machines must at all times be complied with.
Note:
The elevator machine’s electrical system is designed in accordance with the general technical
specifications EN 60 204 – 1.
To ensure flawless and trouble-free machine functionality and to com ly with the EMV
regulations, all and any wiring must be shielded. Ensure that ground loo s are avoided
when grounding the shielding.
Procedure:
1. Motor:
Connection to the power supply must comply with the wiring diagram in the motor terminal
box (see appendix for the motor wiring diagram).
Should an alternative wiring exit be required, unscrew the internal screws in order to turn the
terminal box. Exercise due care when detaching and fastening the fine temperature monitor-
ing wires.
2. Frequency converter:
Connection and setup to the OMS elevator machine must comply with the instructions sup-
plied with the converter. Contact the frequency converter manufacturer should the need arise.
3. Incremental encoder:
The incremental encoder (between motor cover and handwheel) is normally supplied with a 5
m shielded cable and a 2-row 15-pin connector to be appropriately connected to the frequen-
cy converter. The shielding is wired to the plug housing, PIN 12 and the incremental encoder.
Depending on the type of incremental encoder, the connector wiring can vary (see appendix
for encoder electrical connections).
Adapters and extensions are optionally available if other connections (e.g. 3-row, 15-pin) to
the frequency converter are required (see appendix).

3.3 Install the ro e clam
To prevent rope slippage during installation or maintenance work, an optional rope clamp is
available for the traction sheave.
Fit the rope clamp on the side of one of the traction sheave openings (see fig. 3). Ensure that
the lug of the inside clamp bar snaps securely behind the frame of the opening. This prevents
the rope clamp slipping after tightening the locking bolts.
Tighten both locking bolts until the outer and inner bars are approximately parallel to each
other. The inner bar is supported by the frame, thus ensuring that the forces are equally dis-
tributed over all the ropes.
Fig. 3: Side-fitted rope clamp
When using a rope clamp, ensure that:
1. It does not collide with any other parts.
2. It does not get tangled in the upward downward ropes.
3. It does not block anything.
4. The next safety device to prevent rope jumping is not obstructed by the rope clamp. If
necessary, remove the bolt from the safety device to prevent rope jumping.
Pulling the elevator car out of the safety catching device using the rope clamp,
additional „loose rope“ and letting the balance weight fall is prohibited.

4Construction and function
The OMS elevator machine is a high performance drive unit consisting of several components
with various functions.
The extremely high efficiency of the gear unit of 96% means heat loss is so far reduced that
attachments and surrounding mechanical and electronic components are only subjected to low
heat loads. This has a favourable effect on component ageing induced by wear and tempera-
ture.
The gear oil filling is thus normally regarded as lifetime lubrication.
At medium ambient temperatures of approx. 35°C and continuous operation, the oil can be
used for up to 40.000 operating hours. In addition to the routine checks, the lubricating prop-
erties of the oil should be checked every 2 – 3 years (see section 6).
