►Before starting any work, make sure that there are no persons in the shaft or in the vicinity of mov-
ing parts of the drive.
►Prevent unauthorised operation of the controller.
Risk of material damage
The following shall always apply during all work on the installation:
Electrostatic charging
►Keep the electronic assembly in its original packaging until installation.
►Before opening the original packaging, a static discharge must be performed. To do this, touch a
grounded piece of metal.
►During work on electronic assemblies, periodically perform this discharge procedure.
Electronic assemblies are destroyed by defective, interchanged or incorrectly mounted connectors, short-cir-
cuiting or excess voltage.
►Check plugs for mechanical damage.
►Never change pre-assembled connectors or cables.
►Only connect loose or torn off wires according to wiring diagram details if this is possible on site
(suitable material and tools must be available).
►Pay attention to coding pins and latch lugs.
Failure of the safety functions!
Sources of interference in the operational environment can lead to a failure of the FST-3 safety system.
►Do not use the FST-3 safety system in explosive or corrosive environments.
►Do not install the system near sources of interference exhibiting strong inductive or capacitive inter-
ference or electrostatic elds.
Dangerous electrical voltage!
When installing the FST-3 in the control cabinet, live parts may be touched.
►All work on the electrics may only be performed by a qualied electrician.
►Disconnect the system and all components from the voltage supply before commencing with instal-
lation or wiring work.
►Provide ne-wire cables and stranded wires with ferrules.
►Check all sockets, terminals and plug connections prior to switching on.
Danger of falling! Risk of serious injury or death!
Until commissioning is complete, conventional safety precautions are wholly or partially out of operation.
►Dene suitable contingency measures during project planning.
►Make sure that these contingency measures are available and installed until commissioning on site.
►Never congure the system via remote access – only on site.
►Be aware of the active/inactive safety functions at all times during commissioning.
►Check safety-related parameters are working properly each time after conguration is performed or
changes are made.
Safety
Installation, commissioning & check manual – FST-3 13
►Document all commissioning steps and every subsequent change to the system.
►Check all new or modied settings for plausibility through the FST-3 safety system.
Danger of falling! Risk of serious injury or death!
In installation mode, the position-dependent safety functions – especially the safety function for monitoring
speed and acceleration – are out of operation until either one of the four end switches has been taught or the
tape switch has been connected.
►Be aware of the active/inactive safety functions at all times during commissioning.
►On completion of installation work, deactivate installation mode.
2.3 Basic safety principles
During commissioning, the installation of the FST-3 safety system represents a high risk for the lift
engineer, because the system can only offer a low level of safety in principle. In particular, the moni-
toring of the nominal speed (safety brake during Over- speed) is not available. During the rst steps of
commissioning, the lift engineer bears a lot of responsibility, especially for his/her own safety:
Installation mode safety risk:
› In installation mode, the position-dependent safety functions are out of operation until either one of
the four end switches has been taught or the tape switch is connected.
› In installation mode, end switches that have not been taught are not active.
Consequently, it is ensured that the lift engineer can rst move the car for the purpose of tape installa-
tion in the shaft and subsequently, during the teaching of the end switches, enjoys the greatest possible
safety that the system can offer.
Installation and teach mode differentiation:
Installation mode of the FST-3 safety system can be activated or deactivated in combination with a
certain parameter activity in a time-limited conrmation action by means of the auxiliary mode control.
Installation mode must only be accessible to one lift engineer who is aware of his/her responsibility and
is able to correctly assess risk and, where necessary, take contingency measures. In installation mode,
the car can only be moved using the auxiliary mode and inspection control.
Teach mode of the FST-3 safety system can also be activated or deactivated in combination with a
certain parameter activity in a time-limited conrmation action by means of the auxiliary mode con-
trol. It is much less critical than installation mode. All safety functions are in operation. Only the oor
positions and the door zone length can be modied. After activating the teach mode, normal operation
of the lift by passengers is prevented by the FST (landing calls are blocked). The car can be moved using
the auxiliary mode and inspection control or by car calls.
The following basic safety principles apply throughout the entire commissioning phase:
› The lift engineer must know which safety functions are active at every point in time during commis-
sioning. Consequently, the installing engineer can assess whether additional measures are necessary.
› Safety-related parameters must be tested following conguration or modication before safety can be
guaranteed.
› All commissioning steps and every subsequent change must be documented by the lift engineer. An
appropriate template is printed in the user documentation.
› The system must not be congured via remote access (EN81-50, B.1, no.7). In other words, the lift
engineer must be on site to perform conguration changes.
› All changed settings must be checked by the FST-3 safety system for plausibility before becoming
active.
General
› The instructions of the lift manufacturer and the instructions in this manual must be followed during
installation and commissioning of the lift system.
› The shaft must be secured against unauthorised trespassing during installation and commissioning.
Safety
14 Installation, commissioning & check manual – FST-3
› Assemblies, devices and cables must be installed and fastened securely and permanently.
› Loads must be moved with suitable aids (lift trucks, hoisting gear etc.).
› Sharp and pointed tools or other potentially dangerous objects may only be carried along in clothing if
suitable protective measures have been taken to rule out any danger.
› Alcohol and drugs must not be consumed before and during installation and commissioning.
Documentation
› A copy of the installation and commissioning manual must be available to the lift engineer at the time of
installing and commissioning the FST-3 safety system and its components.
› A copy of the installation and commissioning manual and the wiring diagrams must be kept in the con-
trol cabinet at all times after installation.
› The supplied wiring diagrams of the FST-3 safety system are binding. Changes must only be made after
consulting NEW LIFTand must be documented in writing on the system.
› The factory test logs of the FST-3 safety system remain with NEW LIFT.
Electricity
› Regulations for installing and operating electrical equipment (VDE 0100) and regulations of local utili-
ties must be followed.
› The specied distances between different electrical assemblies must be controlled and maintained.
› All installation work must be carried out with the system shut down and off circuit.
› All cables and wires must be installed with sufcient strain relief.
› The neutral wire and earth wire must be routed separately.
› The control cabinet must be supplied with a clockwise rotary eld.
Working in the shaft
› Any work in the shaft requires perfect and permanent communication between the supervisor on the
FST-3 safety system in the motor room and the workers in the shaft.
› Components in the shaft must be arranged or secured in such a way that persons accessing the shaft
for inspection, maintenance or repair purposes are not in danger.
› The maximum load of the lift system must not be exceeded.
› The specied overruns of the emergency end switches in relation to the speed must be observed.
› The emergency installations must not be activated during normal operation.
› All emergency installations and braking systems must be checked for troublefree operation and all
shaft entrances closed off before beginning work.
› Installation and operation are prohibited if other persons could be in danger.
› Workers must be secured against falling.
› In case of any work interruptions, the car must be moved to the lowest stop position, the controller
switched off and the power supply (e.g. UPS) permanently disconnected.
Personal safety equipment of the lift engineer
› Eye protection
› Safety boots
› Protective helmet
› Safety harness
› Clothing suitable to the ambient conditions of the installation location
› Jewellery, watches and similar items may not be worn; a hair net must be used if applicable.
Handling electronic assemblies
› Leave electronic assemblies in their original packaging until installation.
› Touch a grounded piece of metal prior to opening the original packaging to prevent damage from static

First S2 reset, then SG and SK.
1)The actuator can be triggered either through the SHK or the SBR relay.
If the lift brake is being used as an actuator, the monitoring must be performed externally, as per EN81-20, 5.6.7.8.
No valid shaft image available
If no valid shaft image is available, all the safety functions dependent upon it are in a safe state. I.e. the
shaft end switches are open, for example. In this state, the car can only be moved by means of the auxil-
iary mode or inspection control in installation operation.
Safety functions
18 Installation, commissioning & check manual – FST-3
3.1.1 Overspeed (pre-triggering)
The trigger speed of the system is read from the EEPROM data. That is the shutdown speed for the
safety brake. The electrical shutdown is at 92% of the mechanical (congured) trigger speed. This
equates to a ratio of 115% / 125%.
The current speed is determined using the position values and compared with the electrical shutdown
speed. If the speed exceeds the calculated shutdown speed, an emergency-stop signal is initially sent to
the control system (with a short debounce constant) and the SHK is opened slightly later.
The emergency-stop signal to the FST is not relevant to safety and is used to prevent the shutting down
of the system due to excess speed where possible.
This function is not locking, i.e. the SHK is closed again after a system stop and an appropriate waiting
period.

3.1.2 Overspeed (speed limiter)
S2 can be used as a speed limiter. Various systems, such as electrical safety brakes, are possible as actu-
ators that engage the safety gear. The connected actuator system does not form part of the S2 safety
system.
The trigger speed of the system is read from the EEPROM data. The current speed is determined using
the position values and compared with the trigger speed. If the current speed exceeds the trigger
speed, the SHK and SBR are opened.
This function is locking, i.e. the state is saved in EEPROM (power-cycle-protected) and a qualied per-
son is required on site to put the lift back into operation.
3.1.3 Deceleration control circuit
The deceleration control circuit checks whether the normal deceleration is active prior to approaching
the end oors with a shortened buffer stroke in normal operation and opens the safety circuit in the
event of an error (see EN81-20, 5.8.2.2.2).
A velocity curve is calculated as a function of the distance to the previous oor. If this curve is exceeded
(braking distance too short), the safety function opens the safety circuit (SHK relay).
The maximum deceleration of the control system can be congured in installation mode when commis-
sioning the system.
3.1.4 Emergency end switch
The positions of the emergency end switches are dened during teaching in installation mode and per-
manently saved to the S2. They must be active between the respective end oors and prior to contact-
ing the end stops (e.g. buffers). The position can be adjusted within these limits in installation mode.
This function is not locking, i.e. when the car leaves the emergency end switch area, the safety circuit is
closed again.
Any locks (resetting by operating personnel) and return functions that might be necessary (see EN81-
20, 5.12.2.3) have been implemented in the FST.
Additional mechanical emergency end switches at the end points of the hydraulic piston are necessary
for indirect hydraulic lifts. These switches must conventionally be wired in the safety circuit and are not

part of this project.
3.1.5 Door bypass
Inside the door zones, the doors can be bypassed for the purpose of approaching (with open doors),
relevelling and for quick starts. S2 activates the door bypass under the following conditions (EN81-20,
5.12.1.4):
›The door bypass can only be activated in normal operation (not during inspection or auxiliary mode or
when bypass is active).
›The FST has sent the command Door Bypass + Zone Enabling for a specic oor (not safe).
›The car is located in the appropriate door zone.
›The speed is less than 0.8m/s.
All other conditions (e.g. monitoring the relevelling speed) are implemented by the FST because no
safety system is designated here.
3.1.6 Inspection end switch
The inspection end switches limit the range of motion of the inspection control. They make sure that
the car is decelerated before the equipment that ensures the protected space becomes active (if pres-
ent: folding supports or pre-triggered stopping system) (see EN81-21, 5.5.3.4 and 5.7.3.4).
The requirement that the limits of the normal range of motion must not be overrun (EN81-20,
5.12.1.5.2.1 g) is not to be monitored by a safety device and must instead be implemented in the lift
controller.
If a protected space safeguard is not required for the shaft pit (e.g. because nobody is located in the
protected space), the inspection end switch does not have to be active for the shaft pit.
If a protected space safeguard with access door monitoring is required for both shaft ends but only one
lift engineer accesses the car to perform an inspection run, the inspection end switch and the pre-trig-
gered stopping system for the shaft pit protected space may be ignored, since the protected space is
not required.
Inspection end switches are taught in installation mode. In the case of equipment such as folding
supports or a pre-triggered stopping system, the shutdown mechanism is to be selected before this
equipment becomes active. If such equipment is not present – i.e. a natural protected space exists – the
shutdown mechanism is to be selected so that the end oors are not overrun.
3.1.7 Unintended movement with opened doors
Protection against unintended movement (EN81-20, 5.6.7) is aimed at decelerating the car within a
designated range when it is moving away from the oor with opened doors. The monitoring becomes
active once the car is at a oor with opened doors. It ends once the doors are closed. If a movement is
detected which is not permitted, SHK and SBR are opened.
This function is locking, i.e. the state is saved in EEPROM (power-cycle-protected) and a qualied per-
son is required on site to put the lift back into operation.
The safety brake (SBR relay output) is monitored through a positively driven feedback contact. This
corresponds with the safety device required in EN81-20, 5.6.7.8. If the lift brake is being used as an
actuator for this safety function, the monitoring must be implemented externally (acc. to EN81-20,
5.6.7.8).
UCM detection is active in conjunction with the Door bypasssafety function; for the UCM case of
"gear breakage", the Loss of tractionsafety function takes effect and stops the installation in accor-
dance with UCM requirements.
The corresponding reaction time for calculating the stopping distance can be found in the System data
table in chapter Technical data - S2(see Loss of traction - standstill monitor, page 209.)

3.1.8 Access door monitoring
The access door monitoring becomes active when it has been wired and a shaft door to the car roof or
the shaft pit is opened. To this end, separate switches must be provided on the shaft doors. Both access
points are monitored separately.
Normal operation is prevented when access door monitoring is active, i.e. you can only perform inspec-
tion runs when the access door is closed and locked again.
The access door monitoring is locking, and the locking status is saved in EEPROM (even beyond reset-
ting). It can only be reset through the appropriate reset function (separate safety function).
Attention: Via a separate, safe input you congure whether the access monitoring boots in a locked
sate after a reset. This is necessary if there are no external measures to ensure that access during a
reset or power failure leads to a safe state (lock active) during booting.
Examples:
›A non-latching triangular contact for the access to the protected space must boot in a locked state
after a reset, because access during a reset / power failure will not be detected during booting.
Only monostable (non-latching) NC contacts must be used.
3.1.9 Resetting the access door monitoring
This safety function is congured together with the access door monitoring. Both access points (car
roof and shaft pit) are reset separately. Access door monitoring is generally required for short heads
and short pits (EN81-21, 5.5.3.2, EN81-21, 5.7.3.2).
A reset function is also intended for resetting the inspection control in the shaft pit, but which does not
have to reach any particular safety level (EN81-20, 5.12.1.5.2.2). Using the reset function for the access
to the shaft pit, a possibly locked inspection control in the shaft pit is also reset simultaneously (see the
"Inspection switch" safety function in this document).
The access door monitoring is reset under the following conditions:
›A valid reset pulse is detected at the SK reset and SG reset inputs. (The pulse is valid if the button in
question is pressed for a period of 3 to 6s.)
›The related inspection control (SK or SG) is switched off.
›The related equipment that secures the protected space (SK/SG safeguard inputs, e.g. folding supports)
is in an inactive position.
›The SHK is closed, i.e. all access doors are closed and locked and all emergency braking switches are in
the normal position.
Attention: It is possible to reset the access door monitoring for the shaft pit, even though one addi-
tional lift engineer is located on the car roof and vice versa. Normal operation is only possible again
once all access door monitors have been reset separately.
3.1.10 Pre-triggered stopping system
In the case of reduced shaft heads and pits, the protected space for an inspection drive may also be
secured by a pre-triggered stopping system, except using mechanical stops (see EN81-21, 5.5.2.3, EN81-
21, 5.7.2.3). The pre-triggered stopping system safety function is always active in the software and cannot
be deactivated. For the protected space safeguard, a suitable actuator must be connected to the SBR
relay output.
At the shaft ends, the inspection end switches (see corresponding section) rst interrupt the safety
circuit (SHK relay). If the car does not decelerate as a result, the safety brake is also automatically
activated (SBR relay). Once the SBR relay is triggered, the safety circuit (SHK relay) is also permanently
opened. The position of the inspection end switches must be chosen so that the pre-triggered stopping
