1.2.2 Assigned execution features
Type of powering / deactivation continuous current / continuous current end
Brake control parallel
Nominal air gap 0.45 mm
Damping elements YES
Overexcitation 2-fold non-release voltage
2 Conditions
2.1 Above mentioned safety component represents only a part at the protection device against over-
speed for the car moving in upwards direction and unintended car movement. Only in combination
with a detecting and triggering component in accordance with the standard (two separate compo-
nents also possible), which must be subjected to an own type-examination, can the system created
fulfil the requirements for a protection device.
2.2 The installer of a lift must create an examination instruction to fulfil the overall concept, add it to the
lift documentation and provide any necessary tools or measuring devices, which allow a safe ex-
amination (e. g. with closed shaft doors).
2.3 The manufacturer of the drive unit must provide calculation evidence that the connection traction
sheave
–
shaft
–
brake disc and the shaft itself is sufficiently safe, if the brake disc is not a direct
component of the traction sheave (e. g. casted on). The shaft itself has to be statically supported in
two points.
The calculation evidence must be enclosed with the technical documentation of the lift.
2.4 The setting of the brake torque has to be secured against unauthorized adjustment (e. g. sealing
lacquer).
2.5 The identification drawing no. 5019881 or 5019894 or 5019902 or 5019904 or 5019936 or 5019937
including stamp dated 2016-03-18 shall be included to the EU type-examination for the identifica-
tion and information of the general construction and operation and distinctness of the approved
type.
2.6 The EU type-examination certificate may only be used in combination with the corresponding an-
nex and enclosure (List of authorized manufacturer of the serial production). The enclosure will be
updated immediately after any change by the certification holder.
3 Remarks
3.1 In the scope of this type-examination it was found out, that the brake device also functions as a
brake for normal operation, is designed as a redundant system and therefore meets the require-
ments to be used also as a part of the protection device against overspeed for the car moving in
upwards direction and as braking element as part of the protection device against unintended car
movement.
3.2 Checking whether the requirements as per section 5.9.2.2 of EN 81-20:2014 (D) have been com-
plied with is not part of this type examination.
3.3 Other requirements of the standard, such as reduction of brake moment respectively brake force
due to wear or operational caused changes of traction are
not part of this type examination.
3.4 This EU type-examination certificate was issued according to the following standards:

EN 81-1:1998 + A3:2009 (D), Annex F.7 and F.8

EN 81-20:2014 (D), part 5.6.6.11, 5.6.7.13

EN 81-50:2014 (D), part 5.7 and 5.8
3.5 A revision of this EU type-examination certificate is inevitable in case of changes or additions of the
above mentioned standards or of changes of state of the art.
