INTRODUCTION
DESCRIPTION
This system is made up of a SD-BOX signal control box, STAR overspeed governor, T-25 steering mechanism and
ASG-1XX progressive safety gear, everything manufactured by Dynatech. This system operates as a complete
system of protection against car uncontrolled movements with the door open, also known as UCM.
This unit complies with the EN 81-20:2014 and EN 81-50:2014 standard by using the SD-BOX as a signal
management system, the governor as a UCM detection component and the safety gears as braking components.
The entire system stops the car when a UCM occurs at a distance lower than 1 metre in accordance with the standard
requirements.
This protection system is certified as detection and braking device in the scope of protection against car uncontrolled
movements with door open. Furthermore, each component making up the system has also been individually certified
for this purpose; obviously, without negatively affecting its certification as overspeed governor and progressive safety
gears when descending and braking component against overspeed when ascending.
UCM certification also includes the combinations between the different versions of these component models.

The assembly of this safety package in an installation exempts the installation itself from requiring the UCM certificate
but not from checking that the unit is in compliance with the standard’s requirements. The installer must be held
responsible for fitting the system in the installation and checking its correct working order.
RISKS AND SECURITY WARNINGS
RISKS
Electrical hazard Do not handle or open the box with its terminals connected to
the SD-BOX´S electrical power supply.
Electrical hazard Never handle the STAR overspeed governor’s interlocking
coil.
SECURITY WARNINGS
•Reference to the manuals for use and maintenance of the different components making up the unit is
recommended before their installation.
•The SD-BOX + Star A3 Beta + ASG 1XX/ASG 1XX-UD + T-25/T-25 UD unit is valid for installations where
the P/Q ratio is above 0.7.

•When a UCM occurs, a qualified technician is required for the installation to be operative again. Once the
problem causing the UCM has been solved, the RESET button must be pressed in order to restore the safety
line and for the system to be operative again.
•SD-BOX´S input signals are typical of the installation controller. As a result, response times of the controller
components are inherent to it even though the total response times of the SD-BOX + Star A3 Beta+ ASG
1XX + T-25 unit are considered as standard.
•In the case of checking the installation or carrying out a manual rescue, it must be checked that the SD-BOX
is set at the correct operation mode for each of these situations so as to prevent unwanted jamming in the
safety gears.
•The parking or anti-creep system, Beta model, incorporated in the Star governor to detect uncontrolled
movements, must always include a 24V coil in order to operate correctly along with the SD-BOX.
•Connection between the STAR governor’s star and ASG safety gear must be designed for this purpose in
order to prevent increasing response times.
DESCRIPTION OF THE UNIT
COMPONENTS OF THE SYSTEM
The components making up the system are:
•CONTROL SYSTEM
The SD-BOX operates as a control systemSD-BOX´SSD-BOXSD-BOXSD-BOX´S.
•GOVERNOR
The Star A3 model two-way governor operates as a UCM actuator.
SD-BOXSAFETY GEAR AND STEERING MECHANISM
The two-way progressive safety gear model ASG-1XX/ASG-1XX UD is used as a braking means.
OPERATION AS A UNIT
As can be seen in FIGURE 2, the SD-BOX electronic device is connected to the installation controller and the Star
A3 governor’s parking system. SD-BOX connection is described in the SD-BOX´S manual for use and maintenance.
The Star A3 overspeed governor with Beta parking system is fitted in the lift’s car or frame and moves together with
them. Therefore, the governor in the machine room and the diverter pulley in the pit can be eliminated. The governor
moves whereas the rope remains fixed attached to the pit via a tensioning system.

FIGURE 2: Components of the system
As displayed in FIGURE 3, the Star A3 Beta governor is connected to the T-25/T-25 UD steering mechanism via an
auxiliary part. This part, not supplied by Dynatech, must be designed so that the drive does not have clearance or
cause extra travel. Ideally, the part must directly go from the governor star to the steering mechanism’s handle as
displayed in FIGURE 3. The installer must check that the safety gears are correctly operated by the governor.

FIGURE 3: Star Governor + ASG 1 XX Safety Gear + T-25 Steering mechanism
FIGURE 4 displays the Star governor’s Beta parking system. It is mainly made up of a coil, which operates the
governor’s interlocking system in case of UCM, and an inductive sensor, which indicates the interlocking system’s
positioning to the SD-BOX.
FIGURE 4: Star A3 Beta Governor
The protection of this system against UCM is as follows: The SD-BOX electronic system compares, at all times, the
status of the car doors and the floor level via input signals from the installation. These signals are:
•Doors closed.
•Floor level or unlocking zone.
•Motor contactor signal.
N.B.: Please check the electrical characteristics in the SD-BOX manual in order to verify the voltage of the signals to
be entere, as well as their nature.
By using these inputs, if the SD-BOX detects that the car leaves door level with doors open, the contactor in the
safety line is activated, which causes the Star A3 Beta governor’s parking system coil to de-energise. This will make

the parking system interlocking system operate on the governor’s centrifugal systems, thus causing the governor to
interlock. After that, the governor’s main pulley will lock and the friction between the rope and the pulley will transfer
the steering mechanism the power required, thus causing the safety gears to stop the car.
FIGURE 5: ASG 1 XX + T-25 Steering mechanism Operation
Under normal conditions, where no UCM is detected, the governor’s parking system coil is energised, thus preventing
the parking system from interlocking the Star governor. Therefore, the system operates with a fail-safe mechanism.
ASSEMBLY AND MAINTENANCE
ASSEMBLY
•SD-BOX:
Only specialised and duly trained staff must carry out the assembly, electrical wiring and start-up. For further
information on assembly, the characteristics of the electrical wiring and wiring diagrams, please refer to the SD-
BOX’S manual for use and maintenance.
•Star A3:
The Star A3 Beta governor will be assembled and adjusted in accordance with the Star overspeed governor's manual
for use and maintenance.
Please check that the governor rope is correctly positioned and that the parking system is correctly operating, by
checking that the coil is energised in normal operation.
•ASG-1XX /ASG 1XX UD+ T-25/T25 UD
The safety gear and steering mechanism will be assembled in accordance with the ASG-1XX/ ASG-1XX UD+ safety
gear and the T-25/T-25UD steering mechanism’s manuals for use and maintenance.

Please check the distance from the safety gear brake shoe to the guide rail. Please also check that the auxiliary part
connecting the Star A3 Beta governor to the T-25/ T-25 UD steering mechanism is suitably fitted and operates
correctly.
Please check periodically that no damage has occurred, which may put the normal use of the lift at a risk. In case of
excessive wear on the safety gear’s friction components, they can be replaced. Visual inspection is enough.
