This documentation applies to the following products:
•
Hydraulic Orbital Motor type OMS, OMSW and OMSS
•
Hydraulic Orbital Motor type OMT, OMTW and OMTS
•
Hydraulic Orbital Motor type OMV, OMVW and OMVS
General information
Purpose of this document
This User Manual has been prepared by the manufactor in order to provide important information
regarding the safe installation, operation and maintenance of ATEX certified motors.
This User Manual is a supplement to existing product instruction as ATEX components are subjected to
some limitations compared to standard components. The limitations are described in this ATEX
instruction.
It is intended for machine/system manufacturers, fitters and service technicians. Please read this User
Manual carefully before you work with and start-up the motor.
This User Manual must lie close to the motor.
Manufacturer responsibility
The manufacturer declines any responsibility in case of:
•
Use of the product not according to safety regulations and legislation valid in the user’s country.
•
Use of the product in operating conditions not allowed according to the product technical
documentation.
•
Improper installation: the instructions given in this User Manual are not followed or not properly
followed.
•
Hydraulic system problems.
•
Modification of the product.
•
Operations executed by personnel not properly trained or not assigned to such a kind of operations.
Product safety
The safety of the product depends upon the strict observation of the indications given in this User
Manual: in particular, it is necessary to:
•
always operate within allowed product working operating conditions (please refer to the Technical
Information of the motor in usage).
•
always perform an accurate ordinary maintenance activity.
•
assign the inspection activity as well as maintenance activity to duly trained personnel.
•
only use original spares.
•
always use the product according to the indications you find in this manual.
Intended use
Hydraulic motors converts hydraulic energy (pressure, oil flow) into mechanical energy (torque and
speed). They are designed for mobile and stationary applications.
The motors fulfill the explosion requirements with the Directive 2014/34/EU for the category shown on
the name plate.
The Danfoss OMS, OMT and OMV motors have the following identifying name plate. The name plate
provides essential information and specification for correct and safe use.
This identifying plate has to be maintained so that the data can be clearly read; consequently, a periodic
cleaning of the plate is required.

Name plate data for ATEX-specified OMS, OMT and OMV motors
The Danfoss OMS, OMT and OMV motors are marked for application in Group II Category 2 systems.
II 2 GD ck TX
* T-codes are listed in: T codes and maximum surface temperature for OMS, OMT and OMV motors on page
6
Explanation of the different groups:
•
Group II category 2 means it is possible to operate in following ATEX zones: zone 1 and zone 2; zone
21 and zone 22.
•
G = may operate in a gaseous environment (zone 1 and 2).
•
D = may operate in a dusty environment (zone 21 and 22).
•
c = Ignition protection by “constructional safety”
•
k = Ignition protection by “liquid immersion”
•
TX = Maximum surface temperature mainly depends on operating conditions (like e.g. ambient and
oil temperature).
Production place and date of the motor - OMT sample:
The production location and date of the motor is shown at the first 5 digits of the serial no.
Example: Serial no: N45123094
Five first digits are N4512
N is the manufacturing location (N=Nordborg ; W = Wroclaw)
4 is the year (It stands for the last digit in the possible decade).
51 is the week
2 is the day (2 = Tuesday)
The last four digits are a consecutive number.
