2Safety Instructions for OMS Escalator Machines
2.1 A licable Use
The OMS – escalator traction machine EC 2 - 25 is solely intended for usage in escalators and
passenger conveyors (travelators, moving walks) for public transportation according to EN 115
and DIN EN ISO 12100 part 1 + 2.
The installation and use of the EC 2-25 for other purposes is not applicable. The OMS ANTRIEB-
STECHNIK is not liable for personal injury and or damage resulting from none applicable usage.
All Planning, installations and maintenance work may only be carried out by qualified personnel.
Qualified personnel are such who having studied for qualifications, or are experienced, or have
received instruction and have the knowledge relating to the relevant standards and directives,
safety regulations and local knowledge required to install and maintain the machine and be able
to recognise and access the risks appertaining to this machine. (Qualified Personnel, as defined
in IEC 364).
This OMS – escalator drive is applicable to the 9th Directive of the Machine and Product Safety
Law (9. Verordnung zum Geräte- und Produktsicherheitsgesetz [Maschinenverordnung]) and the
2006 42 EC Machine Directive. It is part of a machine, namely an escalator or a travelator and is
therefore not liable for CE certification.
The commencement of regular use is not permitted until the traction machine has been correct-
ly installed into the escalator or travelator and the manufacturer has applied the CE label to the
escalator or travelator to certify that the safety requirements have been fulfilled for the com-
plete product machine as supplied by the manufacturer.
All other required regulations and certificates (e.g. applicable to general use, maintenance and
inspections) remain in force.
The drive manufacturer only respects the warranty for operation and safety of the drive if it is
has been erected, maintained and operated according to the printed specifications supplied indi-
vidually with each drive. The warranty is void if the parameters outlined in the operating,
maintenance and control documentation have been exceeded. An incorrect installation or incor-
rect use of the system, and or violation of the standards outlined above, lead to a complete and
absolute none liability of the drive manufacturer.
The used motors are generally suitable for frequency inverter operation, provided the slew rate
limit of the motors is adhered to. Customer supplied frequency converters must be set up ac-
cording to their instruction sheets, in order to comply with the requirements of the OMS-
Escalator Machine, and with the national EMI directives.
The escalator traction machine is only intended for installation and usage in an enclosed area.

OMS Drives may only be stored, erected and run in dry closed areas. The IQ OQ representative
and the user must ensure that adequate measures are taken to avoid a contamination with
building dust and or dirt.
Stopping of a running traction machine is via frequency inverter control or via the machine
brake. In emergency situations braking may be via an external, auxiliary brake on the escalator
main shaft. Make sure that when braking with such an auxiliary brake onl , the traction ma-
chine is not dynamically overloaded. When braking with an auxiliary brake, this should prefera-
bly be engaged together with the machine brake.
OMS-Escalator machines may only be operated when in technically good condition and within
the parameters as described by OMS.
Applicable use also includes the following:
•Working according to the supplied instructions,
•Observing the regulatory safety and environmental requirements,
•Adherence and observance of the Escalator documentation and regulations.
2.2 Non A licable Use
OMS Drives may not be operated in potentially explosive or environmentally aggressive areas.
Further operation is not permissible once the pre determined wear points have been achieved.
Permissib e Limits:
•max. Motor Speed: refer to technical documentation;
•Local ambient temperature during operating min.: 0° C max. 45° C and 55° C for 1h.; with mo-
tor heating from -10°C up to 45°C, with additional gear box heating from (for intermediate
gear box too)-35°C up to 45°C
•Local ambient temperature without operating: -20°C max. 60°C
•The technical data and specifications on the Motor Data Label are only valid for an installation
height up to h ≤ 1000m over NN.

chine operates immediate y after the brake has been re eased.
•At initia start-up, the motor must acce erate to norma speed and be run for
min. 30 seconds, before a ower standby speed can be used! This is mandatory
to warrant ubrication of the upper Hypoid bearing via the integra oi pump.
2.3 Warranty and Liability for the Escalator Drive
•The drive manufacturer only respects the warranty for operation and safety of the drive if it is
has been erected, maintained and operated according to the printed specifications supplied
individually with each drive.
•The warranty is void if the parameters outlined in the operating, maintenance and control
documentation have been exceeded.
•The customer is responsible for the qualified installation of the drive by certified personal.
•If damage or other problems are found on the Escalator or the drive, then the system must be
disabled, otherwise the operator will be liable for all damage and injury appertaining thereto.
•An incorrect installation or incorrect use of the system, particularly with respect to the forbid-
den procedures outlined above, lead to a complete and absolute none liability of the drive
manufacturer.
•This is also applicable, when after damage has occurred, the operator and or the installer and

The electrical connections should be connected as per the diagram in the Motor Terminal Box.
(See also: Appendix, Electrical Connections). Should a different wiring exit position be required,
the Terminal Box can be turned by loosening the internal fixing screws and repositioning the
Terminal Box. Fasten the terminal box and tighten the inner screws with torque of 20 Nm.
Please take care when adjusting the fine wiring of the temperature monitor switches..
2. Brake So enoid:
The brake solenoid (Two Circuit Double Stroke Expanding Magnet) must be connected according
to the various requirements (see connection of the brake magnet to the power supply in the Ap-
pendix). Supply voltage generally 230V AC (± 10% max.)
a) for a single circuit brake (O-21 or O-31) both left and right solenoid circuits are controlled
by one module.
b) for a double circuit brake both sides of the solenoid (O-22 or O-32) are controlled by an in-
dividual module. For earthquake unsafe regions the electrical connection of the two mod-
ules is made individually, too (O-23 or O-33).
Attention! Specia note appertaining to Dua - and Dup ex machine: The motors
and the brake so enoids must be connected in a way if one so enoid wi fai out
both motors are to stop!

4Construction and Function
The OMS escalator machine is a high capability traction machine, compromised of several sub-
units for different tasks.
Due to the high efficiency ratio of approx. 96% the machine generates little excess heat, this
ensures that the modules and aggregate parts and electronics are not exposed to excessive tem-
peratures and therefore a detrimental effect – ageing and wear – on these parts due to temper-
ature influence is kept to a minimum.
The oil shelf life – dependant on usage and environment – usually reaches 30.000h or more.
For average ambient temperatures of approx. 30°C and under continuous operating methods the
oil can be used for up to 30,000 operating hours. In addition to the usual checks every 2 years
the lubrication properties of the oil should be checked for (see chapter 6).
