coder
iInformation
Additional information and recommendations
1.2 Intended use
The encoder is a precision measurement device for the acquisition of speed/position in-
formation for the control of drive units and the provision of electronic output signals for
downstream devices.
The encoder must not be used for any other purpose. The function of the encoder is de-
scribed in this mouting instruction. The customer must check the suitability for the purpose
intended.
-
ting, electrical commissioning or any other work with the encoder or system is to be perfor-
Do not put encoder into service if there is any visible evidence of damage.
Do not operate encoder beyond the limit values stated in this mounting instruction.
Any risk of personal injury, damage of the system or company equipment due to failure or
malfunction of the encoder must be eliminated by corresponding safety measures.
Warning
Disregarding intended use could result in serious injury or damage to property.
1.3 Exclusion from liability
The manufacturer is not liable for any damage to persons or property resulting from unin-
tended use of the encoder.
IMPORTANT NOTES
2/32 MB244EN - 11171691, 16A3, Baumer_HMG10-SSI_II_EN
1.4 Maintenance and lifetime
The encoder may be only opened as described in this instruction. Repair or maintenance
work that requires opening the encoder completely must be carried out by the manufactu-
rer.
Alterations of the device are not permitted.
The expected operating life of the device depends on the ball bearings, which are equipped
with a permanent lubrication.
In the event of queries or subsequent deliveries, the data on the device type label must be
quoted, especially the type designation and the serial number.
1.5 Approvals and warranty
EU Declaration of Conformity meeting to the European Directives.
UL approval / E256710.
We grant a 2-year warranty in accordance with the regulations of the Central Association of
the German Electrical Industry (ZVEI).
iwarranty seal
Damaging the warranty seal on the encoder invalidates warranty.
1.6 Storage temperature and disposal
The storage temperature range of the encoder is between -15...+70 °C (caused by pa-
cking).
Encoder components are to be disposed of according to the regulations prevailing in the
respective country.

2. SAFETY AND ATTENTION INSTRUCTIONS
2.1 Safety instructions
Explosion risk
» -
Risk of serious injuries due to rotating shafts
Hair and clothes may become tangled in rotating shafts. Touching the rotating parts
can cause extremely serious injuries.
» Before all work switch off all operating voltages and ensure machinery is statio-
nary.
» Prevent reconnection operating voltages by third parties.
Risk of serious injuries due to consequential damages
Plants can be deregulated due to malfunction or faulty signals of the encoder.
» Damage caused by faulty operation or by a malfunction of the encoder must be
eliminated by corresponding safety measures.
Risk of burns due to formation of heat
The encoder heats up at higher speed so there is a serious risk of burning shortly
after the machine has been turned off.
» Examine carefully whether the encoder overheats. Wear suitable gloves if neces-
sary.

2.2 Attention instructions for mounting and operation
)Risk of destruction due to electrostatic charge
Electronic parts contained in the encoder are sensitive to high voltages.
» Do not touch plug contacts or electronic components.
» Protect output terminals against external voltages.
» Do not exceed max. operating voltage.
)Risk of destruction due to mechanical overload
Rigid mounting may give rise to constraining forces.
» Never restrict the freedom of movement of the encoder. The installation instruc-
tions must be followed.
»
)Risk of destruction due to mechanical shock
Violent shocks, e. g. due to hammer impacts, can lead to the destruction of the
sensing system.
» Never use force. Assembly is simple when correct procedure is followed.
» Use suitable puller for disassembly.
)Risk of destruction due to contamination
Dirt penetrating inside the encoder can cause short circuits and damage the optical
sensing system.
» Absolute cleanliness must be maintained when carrying out any work on the open
terminal box.
» When dismantling, never allow lubricants to penetrate the encoder.
)
-
ting an encoder, secured to a shaft by adhesive may lead to the destruction of the
unit.

MOUNTING / HOW TO PREVENT MEASUREMENT ERRORS
12/32 MB244EN - 11171691, 16A3, Baumer_HMG10-SSI_II_EN
4.5 How to prevent measurement errors
To ensure that the encoder operates correctly, it is necessary to mount it accurately as
described in section 4.1 to 4.4, which includes correct mounting of the torque arm.
The radial runout of the drive shaft should not exceed 0.2 mm (0.03 mm recommended),
to prevent an angle error.
An angle error may be reduced by increasing the length of L1*. Make sure that the length
L2 of the torque arm, see below, is at least equal to L1**.
mech can be calculated as follows:
mech
with R: Radial runout in mm
L1: Distance of the torque arm to the center point of the encoder in mm
Example:
mech equals ±0.025°.
iFor more information, call the telephone hotline at +49 (0)30 69003-111
L1
* For this different braces for the torque arm are available on request.
** If L2 < L1, L2 must be used in the calculation formula.
