To secure the safety gear onto the frame, we recommend a 79.09 Nm tightening torque for grade 8.8 M12
bolts, and of 111 Nm for grade 10.9 bolts.
⚠Safety gear position:
a) The safety gears should be assembled in the position displayed in Figure 4
b) The roller for upwards jamming is indicated with letter “A”. That is to say, roller “A” should be on the
upper part of the safety gear.
c) The roller for downwards jamming is indicated with letter “D”. That is to say, roller “D” should be on
the lower part of the safety gear.

During assembly, the safety gear should be perfectly aligned with the guide rails, both vertically and
horizontally. Improper assembly may cause the safety gear to function incorrectly.
Figure 7: Improper assembly
3.2 SAFETY GEAR ADJUSTMENT
The guide rail's position in the block should be adjusted as follows: The side of the guide rail 1.5 mm from the
brake shoe; the head of the guide rail 3 mm from the back of the groove (see drawing DYN 05.C001.01 / DYN
05.C002.01).
⚠In order to avoid problems with the installation’s normal operation, it is very important that the person
carrying out the installation rigorously observes the distances mentioned in this item.
⚠It should be checked that the safety gear is placed so that the rollers for downwards jamming, marked
with the letter “D”, are on the bottom part of the safety gear, as is shown in item 3.1.

3.3 COUPLING THE DRIVING BAR
It is the responsibility of the person who installs the safety gear to properly position the driving bar in relation
to the safety gear, as well as to properly synchronise the safety gears controlled by that driving bar. The driving
bar is properly positioned when the trolley’s pivot is in the protection plate’s central position.
Once it has been fitted and the safety gear’s roller’s trolleys have been attached to the driving bar’s tripping
bars, it should be checked that both trolleys operate simultaneously, controlled by the driving bar. This should
be checked in both directions, ascending and descending.
The overspeed governor should generate a minimum force that it should be twice the force to ensure the
synchronized performance of the safety gears.
⚠The Standard demands that the installation incorporate an AC-15 or DC-13 safety contact as defined in
EN 60947-5-1.
3.3.1 USING DYNATECH’S T-2 DRIVING BAR
The PR-2500-UD.V35 safety gear may be synchronised by assembling Dynatech’s T-2 driving bar. For more
information concerning T-2 driving bar assembly, please consult its manual: DYN06 –Instructions T-2.
⚠T-2 driving bars cannot be used with PR-2500-UD.V50 safety gears
⚠It is not recommended to exceed a maximum force of 1900 N is not recommended with the governor.

4 INSPECTIONS AND MAINTENANCE
4.1 CHECKING THE SAFETY GEARS
For the safety gears to function correctly, their proper assembly and adjustment must be verified as well as
the sturdiness of the unit’s connection to the car and the guide rails, as is stated in the standard EN 81:1+A3.
It is recommended to follow the standard’s provisions for inspections and tests, both for commissioning and
regular testing.
The safety gear model’s behaviour curves may be requested from Dynatech based on its (P+Q) and the
installation’s rated load when tested dynamically with suspensions included.
The proper synchronisation of the safety gears may be checked by
verifying that the roller’s track is marked on both guide rails and that
they have a similar length, with the difference between the two sections
not being more than 4 cm.
The requirements for regular tests should not be greater than those for
commissioning. It is therefore recommended to always use the same
load (P/Q) and speed conditions. For better control, the maintenance
worker should have a safety gear operation record, where he or she
records the serial number and number of operations. A visual
inspection is sufficient to check that the installation has not been
damaged, see section 4.3.1.
It is not necessary to work on the safety gears due to their regular tests,
as long as their braking distance does not exceed double the distance
recorded from the first commissioning test.
After operating the safety gear in free fall, it is recommended to contact
Dynatech, or your nearest supplier, directly, who will indicate how to
proceed.

4.2 PRECAUTIONS
It is recommended to keep in mind the following items:
The factory protective covering should be removed from the guide rails. In addition, it should be
checked that there are no other objects, such as screws, brackets, etc. that may interfere with the
safety gear or its driving bar.
It should be visually checked that the safety gears are in working order, that they are not dirty or greasy
inside.
After any inspection or test where the safety gears were tripped, it should be checked that the safety
gears have not been damaged.
It is recommended to perform the tests near the car door to unload the car in order to facilitate
unjamming the safety gears.
The authorised personnel should always take the necessary precautions when tripping any of the
previously installed safety gears.
4.3 MAINTENANCE
Both for maintenance and inspection, the following maintenance operations should be performed after tripping
the safety gears.
4.3.1 LIST OF MAINTENANCE OPERATIONS
Safety gears:
Check that there is no interference between the shoe and the guide rail, nor between the rollers and
the guide rail.
Check the brackets and the clearance between the safety gears and the frame, readjust it if necessary.
Clean any remaining grease, shavings or dust inside the safety gear’s housing.
Check that there is no external element inside the safety gear’s housing.
Check that the rollers spin freely and are not damaged or worn.
Check that the connection between the rollers and the driving bar has not been damaged and spins
freely without being blocked.
Visually check that the safety gears are not damaged in general.
Check that the driving bar is in good condition and that the safety gears are correctly synchronised.
Check that the car’s floor does not have more than a 5% slope in comparison with its normal position.
Check that the governor’s attachment moves correctly and is in good condition.
Check that the safety electrical contact has been correctly assembled and is functioning properly.
Guide rails:
Clean and remove any type of dirt or dust from the guide rails.
Eliminate the marks or burrs caused by tripping the safety gears.
Apply a thin and even layer of lubricating oil, as indicated in item 2.2, section b) of this manual, on the
guide rails.
4.3.2 CORROSION.
All DYNATECH safety gears have anti-corrosion protection. However, it should be regularly checked that the
safety gear’s mobile elements are in perfect working condition; a jamming test will not be required, just a simple
verification that all the parts are moving freely, as well as a visual inspection of the general condition of the
surfaces.
These verifications should be done more regularly, as the maintenance worker considers necessary, when the
installation is in an especially corrosive environment.
4.4 STORAGE AND SERVICE LIFE
The safety gear should be stored in a cool, dry place. It should be protected from excessive lighting. It should
never be exposed to severe weather conditions.
Storage temperature: 5 - 40ºC
Storage humidity: 15 - 85% without condensation.
The safety gears’ packaging should be clean and dry, so that they can be clearly identified.

INSTRUCTIONS : PR-2500-UD Cod : DYN 05.01.08
Date: 15/04/2016 Revision: 08
10
It is not permitted to place constant or unbalanced loads on a package, which may cause the package to be
bent, or to allow products to be stacked one on top of the other. When stacking products or packages, the
storage height should take into account their load and stability.
If the criteria established for proper maintenance are observed, the safety gears may have the same service
life as the rest of the installation’s fixed elements provided that their proper functioning is ensured and
controlled. The element’s service life is not affected by grease, dust or dirt due to the shaft’s condition or to
environmental conditions differing from those stated in this manual.
5 UCM
5.1 UCM SYSTEM’S PRELIMINARY DESIGN.
According to UNE‐EN 81‐1:1998+A3:2009, lifts should be equipped with means for stopping uncontrolled car
movement (UCM). These means should detect UCM and stop the car. This stop must occur at a maximum
distance below 1 m (among other requirements).
The safety gears may be used as a braking device for stopping the uncontrolled movement.
The values for the safety gear’s braking distance may be calculated beforehand, but several installation
parameters must be taken into account. The more information that is known about the physical elements that
make up the system, the closer the theoretical value will be to the actual value.
These are theoretical values and may only be used in the system’s preliminary design. The installation’s
compliance with the standard requirements is pending.
5.2 SAFETY GEAR BRAKING DISTANCE CALCULATION
The detailed calculations can be found in the manual: DYN 62.04 –UCM. Braking distance.
