Guidelines on the Declaration of Conformity
A conformity evaluation has been carried out for the product in terms of the EU Low Voltage Directive 2014/35/
EU, the Electromagnetic Compatibility (EMC) Directive 2014/30/EU and RoHS 2011 / 65 / EU with 2015 / 863
EU.
The Declaration of Conformity is laid out in writing in a separate document and can be requested if required.
Guidelines on the EMC Directive (2014/30/EU)
The product cannot be operated independently according to the EMC directive.
Only after integration of the product into an overall system can this be evaluated in terms of the EMC.
For electronic equipment, the evaluation has been verified for the individual product in laboratory conditions,
but not in the overall system.
Guidelines on the EU Directive 2011 / 65 / EU (RoHS II) with 2015 / 863 EU (RoHS III - from
22 July 2019), which restrict the use of certain hazardous substances in electrical and electronic devices
as well as in products / components (category 11), the proper operation of which is dependent on electric
currents and electromagnetic fields. Our electromagnetic products / components fulfill the requirements
laid down in the RoHS Directive(s), taking into account the valid exceptions (according to Appendix III
and IV RoHS (2011/65/EU) with delegated Directives (EU) 2018/739-741 from 01.03.2018 for Category
11 – until 21 July 2024) and comply with the RoHS.
Guidelines on the Machinery Directive (2006/42/EC)
The product is a component for installation into machines according to the Machinery Directive 2006/42/EC.
The product can fulfil the specifications for safety-related applications in coordination with other elements.
The type and scope of the required measures result from the machine risk analysis.
The product then becomes a machine component and the machine manufacturer assesses the conformity
of the safety device to the directive. It is forbidden to start use of the product until you have ensured that the
machine accords with the regulations stated in the directive.
Guidelines on the ATEX Directive
Without a conformity evaluation, this product is not suitable for use in areas where there is a high danger
of explosion. For application of this product in areas where there is a high danger of explosion, it must be
classified and marked according to Directive 2014/34/EU.
Guidelines on the REACH Regulation (EC No. 1907/2006)
of the European Parliament and of the Council Concerning the Registration, Evaluation, Authorisation and
Restriction of Chemicals. This regulates the manufacture, placing on the market and use of chemical substances
in preparations, under certain conditions also pertaining to substances in products. mayr®power transmission
exclusively manufactures products (articles: Overload clutches, shaft couplings, electromagnetic brakes /
clutches, permanent magnet motors and the appropriate control modules / rectifiers) in accordance with the
definition in Article 3 of the REACH Regulation. mayr®power transmission is aware of its responsibility towards
the environment and society. As a matter of precaution, we pay attention to particularly critical substances
in the supply chain and strive to avoid using any such substances completely or to replace them in the near
future. To our knowledge, when used for their intended purpose and disposed of correctly (recycling), the
contained substances pose no threat to health or environment.
Preventative function monitoring
Through the monitoring of different parameters, the ROBA®-brake-checker recognises safety critical operating conditions of the
brake in advance, as well as acute faults (e.g. line breakage). These are determined as they occur and are notified to the user
as a warning before the brake can no longer be operated.
Only the mechanical switching function is checked. Conclusions on the braking torque are not possible (e.g. reduced friction
value due to oiling of the brake lining)
Possible causes for the warning:
• Increasing wear
• Rising coil temperature
• Falling supply voltage
• Line voltage drop on feed lines to the brake

Function
The ROBA®-brake-checker plus DC monitoring module is
intended for use with an supply voltage DC of 24 V. The
monitoring module monitors the movement of the armature
disk and emits the determined switching condition via
control terminal (signal output).
Critical conditions (line breakages, wear, excess temperatu-
re) can be recognised and the respective signal can be emit-
ted via control terminal (error output).
It is possible to select between fast and slow disconnection
via the input F/S on the control terminal.
Louder switching noises are generated on the brakes in
case of fast switch-off than in case of slow switch-off.
The movement detection feature of the armature disk is
based on the detection of electromagnetic changes in the
brake. If, due to unfavourable external influences, the secu-
red detection cannot be ensured, it is possible that the
signal and error outputs do not correspond to the expected
state (plausibility).
Dimensions (mm)
CAUTION The ROBA®-brake-checker with integrated
DC-side disconnection is not suitable for
being the only safety disconnection in ap-
plications!

Voltage reduction mechanism
After a brake-specific overexcitation time period, the intelli-
gent voltage reduction mechanism mode adjusts to the pre-
set holding voltage. Manual adjustment of the overexcitation
time is not necessary.
Continuous drop-out recognition
The continuous drop-out recognition can detect the follow-
ing situation and signal it via the outputs:
Brake is energised --> Undesired movement of the armature
disk for closing the brake (drop-out of the armature disk).
Changes of the output signals:
Control terminal
16:
OUT DC --> 0 V
Control terminal
15:
ERR DC --> 0 V
Possible Causes
• Excessive temperature
• Marginal dimensioning
• Mechanical influences
Release Monitoring
The release monitoring recognises the movement of the ar-
mature disk for opening the brake after switch-on as well
as the movement of the armature disk for closing the brake
after switch-off.
The release monitoring can be deactivated for certain appli-
cations in order to prevent errors.
Possible applications:
• Parallel operation of several brakes
• Damped brakes
• Unspecific brakes
Switch-OFF
Fast switch-off
If short engagement times are desired, fast switching should
be used (FAST).
Here, the ROBA®-brake-checker monitoring module limits
the switch-off voltage to approx. 60 VDC.
DC-side disconnection is signalized by the red light-emitting
diode flashing at the moment of switch-off.
Optional (customer-side): External fast switch off
A single-pole energy separation can be achieved by means
of an external switch contact (see wiring example) (tried and
tested principle according to ISO 13849-2). Depending on
the required PL and category, the control element may have
to be designed redundantly in accordance with ISO 13849-1.
Failure detection and corresponding diagnostic coverage
(ISO 13849-1) can be achieved by the following design of
the external switch:
• Feedback with positively driven contacts
• Mirror contacts
The monitoring functions are retained!
Series connection of the isolating contacts at a contact
opening of ≥3mm increases reliability and lifetime.
Slow switch-off
If longer engagement times or quieter switching noises
are desired, slow switching should be used (SLOW) (factory
setting).
Switch-ON
Brake switch-on occurs with a connected supply voltage
(control and power terminal) by closing start (Input) on the
signal side using the voltage DC 24 V or a 24 V control
signal applied there. A green light-emitting diode emits a
signal when the device is switched on. After the changeover
from overexcitation voltage to holding voltage, the diode
continues to illuminate at reduced brightness.
Functional Guidelines
Start process
During each individual start process, all outputs (signal,
error, warning) are reset.
The outputs must be assessed for the plausibility of signal
conditions, signal changes and their correct temporal
sequence.
Jog Mode
During jog mode (fast sequence of switching on and off), no
reliable detection is possible.
After the end of the jog mode, restart the monitoring
function:
• De-energise the brake
• Switch on (energise) the brake again
Repeated switch-on (energisation) before the brake is closed
generates a fault when the maximum current is reached.

For brakes, which do not require overexcitation, the holding
voltage may be lower than the nominal voltage, e.g. on pow-
er reduction to reduce the coil temperature.
Cycle frequency
In order to prevent thermal overload, an upper cycle limit
must be observed for especially high-performance brakes in
operation with fast switch-off.

Device Fuses
Installation of a device fuse into the supply voltage line of the
ROBA®-brake-checker monitoring module.
Short-circuits or earth short-circuits can lead to ROBA®-
brake-checkermonitoring module failures. After fuse
elements have reacted to a malfunction, the ROBA®-brake-
checker monitoring module must be checked for functional
and operational safety (overexcitation voltage, switch-off
voltage, response delay time, holding voltage). The same
also applies after the magnetic coil of the brake has failed.
Intended Use
ROBA®-brake-checker products have been developed,
manufactured and tested as electronic equipment in
compliance with the DIN EN 61000 standard and in
accordance with the EMC directive. During installation,
operation and maintenance of the product, the requirements
for the standard must be observed. ROBA®-brake-checker
products are for use in machines, systems and devices
and must only be used in the situations for which they
are ordered and confirmed. The products are designed
for installation into electrical control cabinets and terminal
boxes. Using them for any other purpose is not allowed.

Guidelines for EMC-compatible Installa-
tion
General:
For electronic equipment that supplies inductive loads (such
as electromagnetic safety brakes or clutches/couplings), the
prescribed measures regarding interference emission as per
the EMC directive can only be considered in combination
with the respective load and not only for the equipment itself.
The EMC directive can only be adhered to by the complete
device or machine.
The measures described for compliance with the EMC
directive for electronic equipment are examined under
laboratory conditions, and cannot necessarily be bindingly
transferred onto the condition of a machine or system in
case of deviations.
Scope of the inspection:
• Monitoring module ROBA®-brake-checker
• released ROBA®-stop safety brake
Interference immunity:
The interference immunity as per the stated standards is
achieved without additional measures.
Interference emission:
The line filter must be installed before the control element
on the mains side (see wiring example on Page 5)
• Observation of the requirements of the
standard IEC60364-4-44/VDE0100-444
• Observation of the remarks/guidelines/in-
structions of the control cabinet, line filter
and frequency converter manufacturer re-
garding EMC-compliant setup
• Observation of the EMC guidelines from
ZVEI and DEMVT
• Observation of the recommendations of
the IECTR61000-5-2
• Mains, power, measurement, signal and
control lines laid separately
• Possibly use shielded, separate line per
brake
• Line shielding must be EMC compliant
and have the greatest possible surface
area
• Ensure good earth connections on the
metal body of the brake
• Avoid antennae effects: Keep lines as
short as possible; do not form rings or
loops
• Signal lines over 30m are considered long
lines and may require special measures
• According to IEC618003, IT networks are
“second environment” category C4 and
require special measures
• Equipment with interference emission lev-
els for industrial usage (environment/class
A, second environment) may require addi-
tional measures when used for domestic
purposes (environment/class B, first envi-
ronment)

and the reduction of such waste through recycling.
Our electromagnetic products (ROBA-stop®/ ROBA-quick®
/ ROBATIC®-clutches) as well as the components required
for control and monitoring (rectifier / brake-checker) and the
DC motors (tendo ®-PM) are frequently used in electrical and
electronic devices within the appropriate area of application
of WEEE, independent of the applicable product categories.
The stated products do not fall within the area of application
of this Directive.
They have been classified as electromagnetic / electronic
components (VDE 0580) or as electronic equipment (EN
50178), and have been determined for installation in devices
for "use in accordance with the intended purpose". Only
products which are to be viewed as devices in terms of the
Directive and not as parts or components are subject to
registration obligations.
Guidelines on UK Directives / Conformity
roducts / components from mayr®power transmission fulfill the requirements for the British economic area due to currently
identical UK and EU directives.
In addition to the CE identification, the UKCA identification is attached to the product.
The UK Declaration of Conformity is available in a separate document.

Guidelines on EU and UK REACH
According to the European Union (Withdrawal) Act 2018, the EU REACH Regulation was transposed into UK law on January
1, 2021, and is known as UK REACH.
REACH and related legislation have been replicated in the UK with the necessary changes to make it workable in a domestic
context.
The fundamental principles of the EU REACH Regulation have been retained in UK REACH.
The remarks on the information obligation according to UK-REACH correspond in content to the REACH Regulation (EC) No.
1907/2006.

Malfunctions / Breakdowns
Disposal
Electronic Components
Products which have not been disassembled can be disposed of under Code No. 160214 (mixed materials) or components under Code No.
160216 (Code No. acc. 200/532/EC), or can be disposed of by a certified disposal firm.
Malfunction Possible Causes Measures
Brake does not release
No supply voltage available Check voltage on input terminal
Brake line interrupted Check brake supply line (check passage)
Line voltage drop on long line Check the brake voltage
Air gap not okay Open and clean the brake, check the air gap. If
possible, adjust the air gap.
No signal
Brake is not permitted Use released brake
Brake is worn Open and clean the brake, check the air gap;
replace the brake if necessary
Incorrect supply voltage polarity Check supply voltage and rotate if necessary
Error (continuous
signal)
Brake release is not recognised Check: Brake is not permitted
Incorrect monitoring module (brake nominal voltage)
Brake drop-out is not detected Brake is not permitted
Check the function of the monitoring module
Break voltage drop Check network stability and reinstate it
Unit temperature over 90 °C Check ambient temperature and, if necessary,
improve the cooling.
Warning
Coil temperature of the brake too high Check effective coil power, ext. Temperature, friction
power
Wear Replace rotor
Supply voltage too low Check and, if necessary, increase supply/output
voltage of the monitoring module; check line length
Clock frequency or PN (coil nominal capaci-
ty) too high Lower clock frequency or PN(coil nominal capacity)
Unit temperature over 85 °C Check ambient temperature. Check clock frequency
and PN.
