Operating manual LL12 4/18 Version 1.6 (01/2017)
The LL12 platform lift is equipped with many sensitive surfaces. Here is an overview:
RED = integrated in the safety circuit (further travel is not possible if activated)
GREEN = direction-related power-off (the lift can travel in the opposite direction)
If one of the direction-related switching surfaces (item 2 / green) is activated, the platform
stops moving and an acoustic warning signal is activated. After two seconds, the platform
drives without any command for 1.5 seconds in the opposite direction and stops. Only then is
the acoustic warning signal deactivated. The ‘release drive’ phase can be aborted only by the
activation of another switching surface, a safety switch or the emergency stop.
After the ‘release drive’ is finished, a travel command contrary to the last active travel
command must be given in order to resume travel.

Testing obligations
Whether or not the LL12 platform lift is subject to an obligatory test depends on the respective
national regulations and is the user’s responsibility. These regulations must be checked and
adhered to. In Germany, a test is obligatory for systems with a lifting height of
≥ 3 m.
In each case, proof must be provided and documented in accordance with EN81-40 before the
first use.
The LL12 platform lift is to undergo maintenance in accordance with the maintenance
instructions at least once per year. We recommend that you take out a service contract with
your dealer.
Use as intended
The LL12 platform lifts are intended for the transport of wheelchair users and/or people with
reduced mobility.
The platform travels between fixed access points along a permanently installed rail, which is
implemented straight. The platform is guided over the stairs or an accessible inclined surface
by the running rail.
The system may only be operated by persons who have been instructed how to do so.

Operating manual LL12 6/18 Version 1.6 (01/2017)
The following transport profiles are foreseen:
Transport of one person sitting in a wheelchair
Transport of one person sitting on the folding seat.
Transport of one person standing on the platform, provided that there is sufficient
headroom and that the person has sufficient standing stability and can hold the hand
grips securely (a separate set of documents is required, available on enquiry).
Transport of an additional person, provided that there is sufficient room on the
platform and that the permissible loading capacity is not exceeded.
A usage profile of 10 start-ups per hour is foreseen (with distances covered of max. 5 m for
each start-up). In the case of longer distances covered, the number of start-ups should be
reduced accordingly (and linearly).
The LL12 chair lift may be only operated if danger due to falling objects (such as flower pots)
is ruled out.
Inappropriate use must be prevented, e.g.:
Exclusive use for loads (if, in rare cases, loads such as shopping or beverage crates are
transported, it is essential to ensure that the load is sufficiently stable and that the
permissible loading capacity is not exceeded).
Loads that protrude beyond the surface area of the opened base may in general not be
transported (e.g. large pieces of furniture).
The LL12 platform lift is not a toy (children).
Operation in potentially explosive atmospheres
Operation outdoors
Operator qualification / technical personnel / qualified persons
The operator of the chair lift must have unrestricted mental abilities. Operators with seriously
impaired vision may be transported only with an attendant, whereby the attendant issues the
drive commands. Furthermore, the operator must have read and understood the operating
instructions.
Technical personnel and/or qualified persons are described in the assembly and service
manual.

Safety and special instructions
Although your lift meets the latest safety regulations, it is essential that you observe
the following safety instructions:
Put the lift into operation only after reading the operating
instructions and adhere to the operating instructions.
Never exceed the permissible loading capacity.
(Residual danger: breakage/failure of the brakes)
Operate the lift only when seated (see transport profile for
exceptions)
Do not use the lift in the case of fire.
Do not allow loosely hanging articles of clothing to get near to the
running rail and the platform when the lift is moving.
(Residual danger: trapping of loose clothing, etc.)
Fold up the lift when not in use.
(Residual danger: tripping over)
Never place your hands near the running rail when the lift is moving.
(Residual danger: crushing)
Be sure to observe the track in the direction of travel when
travelling.
(Residual danger: crushing)
Do not remove, cut through, deform, or use undue force to operate
parts of the lift, cladding parts or operating elements.
Do not push the barriers with undue force, neither while travelling
nor when raising or lowering them.
(Residual danger: falling from the platform)
Stop the drive command immediately if there are obstacles or
articles in or on the track or platform or in the driving area.
(Residual danger: crushing)
Operating manual LL12 9/18 Version 1.6 (01/2017)
Do not remove any labels or signs belonging to the lift.
Have repairs carried out exclusively by specialists.
Do not allow any parts of the body, wheelchair or loads to protrude
beyond the base of the platform.
Do not make any unnecessary movements on the platform, such as
rocking or swinging.
(Residual danger: falling from the platform)
Remove dirt from the lift with a little polish or a damp cloth, not
with a water jet.
The load-bearing equipment and track must be sufficiently well lit
by daylight or electric lighting. The electric lighting must be
independent of timer circuits. Minimum 50 lux at the entry and exit
points or in accordance with the national employee protection
regulations.

Main switch
The main switch (red key) is located inside the platform, behind the cover (p.7, item
4). The key can be removed by turning it anti-clockwise, thus disconnecting the
power supply. (For opening the cover, sees 4.7.1). The main switch must be actuated
by technical personnel.
Deep discharge protector and charging
The LL12 platform lifts are equipped with automatic battery chargers. Charging takes
place automatically when the platform lift drives into a loading station. The batteries
do not require any care.
All LL12 platform lifts are equipped with an acoustic deep discharge protector. This
acoustic signal generator is intended to protect the batteries against deep discharge.
If the battery voltage drops below 22 V, a beep sounds at intervals of approx. 5
seconds. In this case you should drive immediately to the next charging station – if
possible the lower charging station – and allow the lift to charge up there for several
hours (this takes place automatically in the charging station). The beep stops after
proper charging. The sound can be turned off by pressing the emergency stop button;
this has no influence on the charging process.
Checking the loading / overload protection
The LL12 platform lift is equipped with an overload protector (acoustic and visual).
On activation the orange lamp on the hood goes out (p.7, item L2). In addition, the
internal beeper emits a continuous tone in the case of overload. This is based on the
entire load being in the centre of the base of the platform. Reduce the weight if the
overload protector is triggered. It may be sufficient just to shift the weight towards
the running rail.
Battery charger (indicator lamps)
The indicator lamps on the battery charger indicate the respective condition of the
battery charger. Distinction must be made between different versions of the battery
charger.
The meaning of the various colours or indicator lamps is shown on the battery
chargers. The installer will explain this to you in detail once again during the
instruction.
Note: An acoustic signal sounds if the lift, outside a station, is not charged 30
seconds after the last motor movement.
Operating manual LL12 11/18 Version 1.6 (01/2017)
4.5 Fetching and sending the platform lift (standard version)
Before each journey, make sure that the acoustic warning signal works. The LL12
platform lift can be fetched from or sent to another station from any station. To do
this, the key switch must be inserted at the respective station, turned in the
appropriate direction and held in this position.
The platform lift does not react immediately, but after a delay time of approx. 2
seconds.
Note: The platform lift drives from the external control point only in the folded up
condition, i.e. the base of the platform must be folded up and the safety
barriers folded downwards.
Note: an LED is mounted on the radio transmitter for fetching/sending the chair lift.
GREEN: batteries are OK
ORANGE: the battery power is diminishing; renew the batteries at your earliest
convenience
RED: the battery power is very low; replace the batteries immediately
Fetching and sending the platform lift (special version 1) [via the external control
unit, only with 3-position key switch (
p.7, item 2) for a trip with the platform open
via the external control unit]. This option must be activated by a specialist inside the
controller. It must be ensured that no third person can suddenly get/jump into the
path of the lift. Condition: driving area is 100% in view !!!!
The key switch (p.7, item 2) is to be set to position -II-, otherwise as in 4.5.
Fetching and sending the platform lift (special version 2) [via the internal
controller, only with 3-position key switch (p.7, item 2)]. This option must be
activated by a specialist inside the controller.
The platform can be driven via the internal controller in the folded up condition. The
key switch (p.7, item 2) is to be set to position -II- in order to do this. The platform
lift can now be driven via the internal controller (p.7, item 1).
Operating manual LL12 12/18 Version 1.6 (01/2017)
4.5.1 Folding procedure
In the case of the LL12 platform the base folds up and down electrically and the
safety barriers raise and lower electrically. This is performed by means of an UP or
DOWN command issued from a station (see also paragraph 4.5), or via the internal
controller in the case of special version 2. The control button must be pressed and
held (so-called jogging mode) until the folding procedure is complete.
If a malfunction should occur during the folding procedure, the platform must be
folded up or opened manually (see below) and customer service must be informed.
The folding procedure at a step can/may only be carried out by an attendant.
Proceed as follows in order to fold up the platform by hand:
a) Place the safety barriers in the horizontal position.
b) Fold up the base of the platform.
c) Lower the safety barriers so that they rest against the base of the platform.
Proceed in the reverse order to open the platform again and finally raise the safety
barrier at the desired access point right up to the top (vertical).
Operating manual LL12 13/18 Version 1.6 (01/2017)
4.6 Travelling with the platform lift (standard version)
Before each journey, make sure that the warning signal works. The following control
elements are located on the platform:
a) Key switch Function -I- and -0- (
p.7, item 2)
b) Control unit Function UP and DOWN (
p.7, item 1)
c) Pushbutton EMERGENCY STOP (red knob) (p.7,item3)
After driving the platform, insert the key and turn it to position -I-:
! In the case of the LL12 platform, the safety barrier closes electrically when the
button is pressed and held in the desired direction of travel. The platform lift
begins to move once the barrier has closed.
Upon reaching the destination station:
! The platform lift stops automatically (the respective position is set during the
installation).
! In the case of the platform, press and hold the button until the safety barrier has
opened.
Travelling with the platform lift (special version 1) [via the external control unit,
with 3-position key switch (p.7, item 2) for a trip with the platform open via the
external control unit]. This option must be activated by a specialist inside the
controller. It must be ensured that no third person can suddenly get/jump into the
path of the lift. Condition: driving area is 100% in view !!!!
The key switch (p.7, item 2) is to be placed in position -II-, otherwise the procedure
is the same as described under ‘standard version’, with the difference that only the
external control unit is used here.
Travelling with the platform lift (special version 2)
The key switch (p.7, item 2) is to be placed in position -I-, otherwise the procedure is
the same as described under ‘standard version’.
4.7 What to do in the event of an unexpected standstill, e.g. due to a power failure?
We recommend that a working mobile telephone be carried in order to alert the
rescue services.
4.7.1 Manual operation / operation with hand wheel
The LL12 stair lift can also be operated manually. Manual operation must be
performed by technical personnel! The procedure is as follows:
a) Press the EMERGENCY STOP button (p.7, item 3) on the platform.
b) The bolted connection of the platform hood must be remove using the
hexagonal wrench (provided in the envelope).
Operating manual LL12 14/18 Version 1.6 (01/2017)
c) The platform hood is to be raised and secured against falling down by means of
the insertable arms.
d) The bolted connection of the front cladding must be undone using the hexagonal
wrench (provided in the envelope) and the cladding removed.
d) The brake venting lever is to be pressed upwards or downwards whilst at the
same time turning the hand wheel on the end of the motor shaft (see illustration
below
).
In doing so, the direction of travel should always be towards the lower station (less
energy expenditure when turning the hand wheel). The respective direction of
rotation is indicated directly on the hand wheel.
Note: If the cause of the standstill is not clear, it should be assumed that the safety
arrester has been triggered and that its safety switch has led to the lift switching off.
The safety arrester may only be reset by technical personnel. In this case,
proceeded as described in a) to e) above, but first turn the hand wheel in the UP
direction (until the lift has moved approx. 5 cm along the rail), after which the hand
wheel can be turned in the DOWN direction.

Options / extras
Depending upon requirements, the LL12 platform lifts are also equipped
with the following extras.
Lateral drive-on ramp
In some cases (staircases) it is not possible to drive onto the platform over
the two standard drive-on ramps due to the space in front of the first step.
In these cases an additional drive-on ramp is to be mounted on the long
side of the platform (p.7, item 12).
Folding seat
All of our platform lifts can be equipped or retrofitted with a folding seat if
desired (
p.7, item 9.1). The folding seat is intended as a seat for nonwheelchair users who wish to use the platform lift. When folded up, the
seat lies against the platform wall to save space. The folding seat is
equipped with a seat belt, which must be fastened while travelling if the
user is not able to hold on to the barrier or the hand grip with a hand.
