Overspeed governor EOS
Operating instructions
1 General information prior to installation
1.1 Description and main functions
The basic function of this safety device is to detect
overspeed, open the safety circuit and trigger the
safety gear via governor rope - in one or both direc-
tions.
An additional function is also available for supervi-
sion of car movement with open doors (UCM).
Also the acceleration can be measured to engage
the safety gear in case of excessive acceleration -
even before tripping speed is reached.
A tension weight is needed to tighten the rope of
the governor.
The operating range is defined as follows:
EOS D 200mm
The rotary pulley movement is detected by sensors.
This information is derived by a two channel and
self checking safety electronics.
In normal run operation the solenoids are powered
on and do compress internal springs. If the safety
electronics detects any dangerous ride situation
(e.g. overspeed) then the safety circuit is opened
and the electric supply of the solenoids is switched
off. This causes the preloaded springs to expand.
Successively the plungers contact the rotating brake
discs. This mechanical contact causes the synchroni-
sation plate to twist and trigger the internal brake.

Overspeed governor EOS
Operating instructions
EOS D 300mm
1.1.1 Overspeed
When the elevator accelerates and exceeds contact
speed then the safety circuit is opened. If the car
speed still increases and reaches tripping speed then
the internal governor brake is activated and the
attached safety gear engaged.
1.1.2 Unintended car movement with open
doors (UC )
The UCM system (Unintended Car Movement)
should prevent from uncontrolled car movements
with open doors according to chapter 9.11 of
EN81-1:1998+A3:2009, chapter 9.13 of
EN81-2:1998+A3:2009 or chapter 5.6.7 of EN81-
20:2014.
The EOS is used as the detection element, the EOS
Electronic Interface with UPS can be used to provi-
de required functions like the emergency power
supply and the braking element could be a safety
gear, a motor brake, a guide rail brake or a rope
brake. The fulfilling of the standards have to be che-
cked by the operator.
The function to prevent unintended car movement
with open doors can be ordered in several different
types (see „Type“ on the order form and „Type“ on
the type label). „Type 0“ means that there is no UCM
functionality (in this case there is no need to con-
nect ENM1 and ENM2). „Type 1“ EOS is used with a
braking element activated by the governor rope
while „Type 2“ EOS is used with electrically triggered
brakes. See the table on the next page for a detailed
overview.

Overspeed governor EOS
Operating instructions
If the EOS was ordered with the UCM function, the
prevention of unintended car movement (UCM) is
active as soon as the ENM1 and ENM2 signals are
inactive (not connected with +24V). For safety rea-
sons UCM function has to be active when there is no
signal at ENM1 and ENM2. Activation of those sig-
nals deactivates the UCM function.
The actuation of the UCM function complies with
the safety requirements of the EN81 by using two
independent signal generators for the ENM1 and
ENM2 inputs. The EOS checks the synchronicity of
both inputs and generates a secure condition (open-
ing of safety circuit at next stop) if deviations occur.
It is also possible to use one secure signal generator,
only in this case ENM1 and ENM2 can be connect-
ed together directly to the signal generator.
If UCM is active, the output X3 MOVEMENT LIMITE
is activated (contact closed). This output can be
used to give other components feedback about the
condition of the EOS.
If UCM is active, the EOS monitors the current posi-
tion (relative to the position at which the function
was activated and the car movement was complet-
ed - the difference is the way) and speed of the car.
If the speed at the time of activation of UCM was
not zero, the braking of the car (with a certain min-
imum deceleration) is allowed before UCM is actu-
ally set active.
When exceeding the UCM contact distance
C =0,15m or the UCM contact speed TL=0,3m/s or
0,5m/s (depending on ordered parameter) the EOS
trips electrically and - dependent of the type - also
mechanically
For the operation of the EOS with UCM function
certain requirements have to be fulfilled:
• remote trip and remote reset buttons
have to be provided
• an emergency power supply has to
be provided
• control of the inputs ENM1 and
ENM2 with a signal that meets the
safety requirements.
• The signal mentioned above has to
be valid even in case of a power fail,
if the EOS is supplied by the emer-
gency power supply (emergency
rescue)
To facilitate the use of the EOS and the realization
of the UCM-System, all four points are provided
through the use of the EOS electronic interface with
UPS. If the box is used, the UCM-function can be
used independently from the lift controller. The
safety circuit is the only connection to the lift
system.
Operation data (with connected EOS):
• Power supply: 230 V AC ±15%
• Power consumption (battery full): 15 W
• Power consumption (charging): 25 W
• Battery: 24 V; 2,1 Ah (2x12V)
Main supply max. 1A anti-surge fuse.
Safety circuit max. 2A fast acting.

Overspeed governor EOS
Operating instructions
1.1.3 Remote trip and remote reset (TRIP /
RESET)
The rocker switch with the functions TRIP and RESET
is directly connected to the corresponding inputs of
the EOS.
1.1.4 Emergency power supply (UPS)
After applying the supply voltage (230VAC), the
accumulator is automatically charged and then held
on charge and regularly tested. The POWER ON but-
ton lights up if the EOS is supplied.
In case of a power fail the EOS supply automatical-
ly switches to battery supply; POWER ON still lights
up. This state is maintained for 30 minutes. Then the
output voltage is switched off to conserve battery
power for an emergency rescue (POWER ON goes
off).
By pressing the POWER ON button the EOS supply is
switched on again. The POWER ON button lights up
and the EOS is powered up again. This state is main-
tained for 30 minutes again. Then the output volt-
age is switched off (POWER ON goes off).
1.1.5 Control of UC function of the EOS
The inputs ENM1 and ENM2 of the EOS shall be con-
nected to the +24 V supply of the EOS in order to
disable the UCM-function of the EOS (to allow
movement of the car). This information is taken
from the safetycircuit, which usually has a different
voltage and electric potential than the EOS.
Therefore the EOS electronic interface has integra-
ted a galvanically isolated signal transduction from
K1, K2 to ENM1 (channel 1) and independently from
this signal also from K1, K2 to ENM2 (Channel 2) .
(See circuit diagram Chapter 4.1.3)
The states of the two inputs should always be the
same. The state of the inputs is indicated by two
LE s near the connector X6 on the board of the EOS
Electronic Interface (see ENM1, ENM2 in chapter
4.8.5).
uring a power fail the EOS remains active because
of the emergency power supply, but in most cases
the safety circuit won´t. This means that the signals
ENM1 and ENM2 will be inactive. To still be able to
perfom an emergency rescue the EMERGENCY RES-
CUE switch activates ENM1 and ENM2 and therefo-
re allows car movement to rescue trapped passen-
gers.
Since the EMERGENCY RESCUE switch deac-
tivates the safety function UCM, the switch
simultaneously opens the safety circuit to
stop the automatic operation of the lift in
this situation. uring the emergency rescue,
however, it is the responsibilty of the rescu-
ing person to activate the UCM function by
resetting the switch to „0“ again before the
lift doors are opened!
1.1.6 Preventive tripping (optional)
The safety gear will also be engaged if the electron-
ics detect excessive car acceleration (e.g. free-fall)
even before tripping speed is exceeded.

Overspeed governor EOS
Operating instructions
Before starting installation work:
Only properly trained personnel may carry
out work or have access to the installation
site.
- attach safety devices to guard (platform or har-
nesses) to prevent it from falling
- cover any floor openings
- Secure installation tools or objects against acci-
dental falling
- lift shaft openings should be cordoned off and
suitable warning signs should be erected when
working in shaft openings
- work involving electrical equipment should only
be carried out by an electrical engineer or qual-
ified personnel.
1.4 Preparation
Before starting to work it is in your own interest to
ascertain the constructural and spatial conditions
and to check where (workshop or on site) and when
installation operations can or must be carried out. It
is recommended therefore to take into account all
the given circumstances, to plan the various opera-
tional sequences in advance, rather than carrying
them out prematurely and in an unconsidered man-
ner.
On receipt of the delivery, the goods or components
should be checked for correctness and completeness
with the order sheet.
Following should be checked:
- that factory and order number do correspond
- that the details on the name plate does corre-
spond to those on the order
1.5 Advice when working on
safety components
Overspeed governors are classified as safety compo-
nents. It is most important to comply with the stan-
dards and guidelines described in this section as
well as those given in the rest of this operating
manual.
These instructions and especially the section
of safety precautions, should be read and
fully understood before working with the
component.
Safety devices require special attention. It is com-
pulsory that they function perfectly to ensure dan-
ger free installation operation.
Operation of safety devices installed ex-works must
be tested immediately.
If it is necessary to disassemble a safety device dur-
ing servicing or repair, it must be reassembled
immediately after this work has been finished.

2.2 Compatibility
In case of using the EOS as replacement for
an older version check that the used param-
eter is the same.
With parameter Par 1 the certificate no. TÜV-A-AT-
1-13-0339EUGB-2 is compatible with TÜV-A-AT-
1/08/104CEGB/5 and older versions.
All other parameters are not compatible with
TÜV-A-AT-1/08/104CEGB/5 or older Versions.
The parameter shows the predefined setting of the
UCM-detection data. epending on the used param-
eter the UCM contact speed (CL) and the internal
calculation rules vary, what causes different detec-
tion delay times in case of UCM between the differ-
ent parameter sets. Therefore the used EOS parame-
ter set has to be specified in the UCM-system and
the EOS could not be changed to other parameters
without checking the stopping distances according
to chapter 9.11 of EN81-1:1998+A3:2009, chapter
9.13 of EN81-2:1998+A3:2009 or chapter 5.6.7 of

need to be fitted with a collar which is 50
mm high. A corresponding safety collar
must be fastened to the floor before instal-
lation takes place.
If a cement floor is to be poured over the
concrete after installation, bear this in mind
when fitting the collar.
Installation procedure
Always pay attention to the overspeed
governor’s rotational direction during each
stage of installation.
(1) If using a support base it must be screwed to
the governor.
(2) Put the governor (with or without base) into
correct position and align the plumb line over
the centre of the safety gear linkage.
(3) Mark the drill holes and put the stud anchor in
place (stud anchors are delivered with sup-
porting base).
(4) Fasten down the overspeed governor (with or
without supporting base).

Installation procedure
Always pay attention to the overspeed gov-
ernor’s tripping direction during each stage
of installation.
(1) Check the layout drawing to see whether the
overspeed governor is to be fastened to the left
or right hand guide rail.
(2) Fix the guide rail mounting in the desired height
to the rail.
The mounting holes are depending on the
model and guide rail used. For guide rails
T70-T82 use inner holes, from T89 upwards
use outer holes.
(3) Put the overspeed governor into the correct
position and align it in plumb line over the cen-
tre of the safety gear linkage.
(4) Fasten the overspeed governor to the base.
AK dimension (distance rope centre - guide rail) is
adjustable from 140mm to 160mm (5). The distance
between rope centre and guide rail rear is adjustable
from 35mm to 70mm (6).

Put the protection cover on the governor and fix
it with screws. These can be fixed from front side
or from back side - depending on the accessibili-
ty. (see at the picture below)
Once the screws are mounted correctly
(either from front or backside) after the
initial installation it is sufficient to losen
the screws to take off the cover for main-
tenance purposes.
Standard safety cover at EOS standing position Standard safety cover for EOS headfirst option
(D 200mm only)
Fix the cover plate with the EOS fixing screws
between base/concrete and EOS. Mount the stan-
dard headfirst safety cover in the same way like
the standard safety cover for EOS standing posi-
tion. Additional a light pressure with the hand to
the bottom of the safety cover is needed to fix
the cover. Fix with screws like at the standard
safety cover for EOS standing position.
Split safety cover (only for EOS D200mm
standing position)
Put the split safety cover from above, from the
left and the right side, on the EOS. Lock the sin-
gle parts on the back side.
This split safety cover can also be fixed from the
front or the back side. For the fixing with the
screws look at standard safety cover.
