Page 10 Version 2.08 Operating Manual PLK8
4. General description
Our product is designed to fulfil the requirements of conveniently transporting disabled or elderly people up
and down staircases and at the same time be easily integrated into existing surroundings.
One great advantage of the design of our lift is the upper travel rail; which can also be used as a hand rail
when the lift is not in use. The travel rails do not need to be lubricated, this reduces the possibility of soiling by
dust and dirt. When in motion the travelling speed is limited to a comfortable and practical 0.15 m/s and final
drive is achieved by means of a rack and pinion drive.
The noise level during operation is less than 63 dB (A). The load bearing capacity is clearly indicated on the
identification plate.
The operational load is supported on the travel rails by two set of rollers, two diagonal rollers, the gear wheel
and opposing bearing. The supporting rollers are fixed onto two parallel mounted stainless-steel tubes. An
electrical motor propels the unit by means of a gear wheel via a self-locking, form fitting connection to a worm
gear, which is capable of withstanding the horizontal and vertical loads to which it is subjected.
The travel rails are constructed out of an upper stainless-steel tube which also serves as a handrail and a lower
stainless-steel tube with a toothed rack welded to it. The necessary attaching elements are fixed to an existing
wall, stanchion posts or a steel structure.
An arresting device (emergency brake) ensures that in the event of a mechanical or electrical failure, the lift
remains stationary and does not descend down the travel rails.

5. Safety guidelines
! A T T EN T IO N !
The Ascendor platform stair lift is manufactured in accordance with international safety regulations.
Nevertheless, operating errors and misuse can result in heavy injury for the user and/or third parties and
cause damage to the lift, its surroundings and property of the operator!
KEY SYMBOLS:
The following symbols are used throughout this manual
This symbol indicates a step, whereby the failure to observe the instructions in this
manual will result in a dangerous situation where injury or material damage will become
unavoidable.
This symbol indicates a step, whereby the failure to observe the instructions in this
manual will result in a dangerous situation where there is an increased chance of injury
or material damage occurring.
This symbol indicates an operational step where additional references or explanations
are included in this manual.
The lift should only be put into operation after the operating manual has been read thoroughly. The
instructions in this manual shall be observed at all times.
Make sure that the complete travel route is free of obstructions or other people before setting
the lift in motion.
The travel route must be visible at all times when the lift is in operation.
Do not operate the lift when any form of obstruction (person or object) is on the staircase.
Do not allow other people to use the staircase when the lift is travelling as the space available will
become restricted especially where the lift swings through corners.
Never exceed the maximum recommended load.
The operator is responsible for ensuring that the lift cannot be used for any purpose other than
that for which it is designed (e.g. unaccompanied children playing on the lift).
When driving onto the platform with an electric wheelchair, do not drive against the raised ramps,
as these can be overloaded by the forces.
In the case of fire, the lift may be used only once to evacuate the building!
Ensure that no items of clothing, handbags or other material or personal property are hanging on
the travel rails before and during the operation of the lift.
The intention of this chapter is to highlight these dangers. We cannot place enough
emphasis on how important it is that this information is read and understood!
Operating Manual PLK8 Version 2.08 Page 13
Do not rest arms on the safety bars or back of the lift unit during operation.
Don’t put your hands near the travel rail while the lift is in motion.
During operation, ensure that no parts of the wheelchair or passenger protrude beyond the extents
of the lift platform.
Transportation of goods is only allowed when these are stable enough and cannot fall over, move
about or slip off the platform while the lift is in operation.
The lift unit and travel rails must be adequately illuminated at all times, either by daylight or an
electrical light source (min. 50 Lux). The electrical lightning provided must operate independently of
any timing device (e.g. movement sensor).
Always position wheelchair bound passengers on the lift facing in the direction of travel.
The lift is approved for the transport of only one person at any time!
The passenger on the platform should note make unnecessary e.g. rocking or see-sawing
movements while the lift is in motion.
Ensure that the handbrake of the wheelchair has been applied before setting the lift in motion.
Never insert solid objects or pour any form of liquids into any slits or openings of the lift unit.
This applies irrespective of whether the lift is stationary or in use.
Do not remove, cut, deform or handle any parts of the lift with force.
Do not use force during normal operations when opening or closing the safety bars, or while the
lift is in motion. Excepting an emergency, when it is necessary to release a passenger after an
unexpected malfunction of the lift.
The lift operation must be immediately stopped if any objects or form of obstruction are in the
direct path or in the near vicinity of the lift or its travel rails during use.
Do not remove any of the signs or labels which are attached to the lift.
All repair and maintenance work must be performed by trained technicians.
For the necessary qualifications see Chapter 3.2: “Essential Operator Qualifications”.
Repairs to the travel rails (handrail or toothed rack) are strictly forbidden!
Do not use the lift in conditions where a high risk of explosion is present.
(e.g. in the event of a gas leak)
For indoor and outdoor facilities, operating the lift after a temporary or permanent flooding of the
lift is forbidden.
Soiling or dirt on the lift or rails may be removed with the use of commercially available stainless-
steel cleaning spray (light lubrication), or a damp cloth. Never use running water or a hose!
Use the protective cover provided for outdoor installations after every operation of the lift in order
to protect it from environment influences (i.e. rain).
Page 14 Version 2.08 Operating Manual PLK8
Unless required by circumstances, we recommend that the lift is checked at least once a year by a
trained technician. A maintenance record should be kept in a service book or in the table provided
at the end of the Maintenance and Service Manual. (Part 3 of the Original User Manual).
We advise that an Ascendor approved partner is entrusted with this work.
If the lift is to be operated without the use of third party assistance, it’s essential that extra
precautions are provided so that –in case of an unforeseen still stand (e.g. mechanical fault, power
failure or breakdown) –the passenger can summon help and assistance.
We recommend fitting an “emergency call device”(see Chapter 9 - Optional Extras) or that
passengers always carry a cordless or cellular telephone with them at all times when using the lift.
It is important that the recharger is connected to a permanent electrical supply. As soon as the lift
is stationary and parked at the upper or lower station recharging will automatically begin.
Only with the batteries fully charged can the operational function of the lift be guaranteed.
On outdoor units the user must wear the appropriate clothing to protect themselves against wind,
weather and seasonal temperatures and in case of an unforeseen breakdown.
The transport of pets on the platform is forbidden on safety grounds.
The key in the wall mounted remote control box can only be removed
when it has been turned into the ‘0’ position (OFF).
The lift should be operated at least once every 2 weeks.
Operating Manual PLK8 Version 2.08 Page 15
6. Operating the lift
The Ascendor platform stair lift is fitted with a “dead man’s handle”.
The operating principle ensures that the stair lift will only remain in motion as long as the travel button on the
lift or the remote controls is pressed. This feature is designed to avoid panic and provide the user with the
feeling of security when the lift is in use.
6.1 Wireless remote control
The remote-control unit allows the operator the greatest amount of freedom when using the lift.
You are no longer dependent on the controls mounted directly on the lift or at the upper or lower stations.
You are free to control the lift via the handheld remote-control unit which can be carried around on one’s
person. The receiver is mounted inside the frame of the lift unit and transmits the commands from the remote
control to the lift.
Please note; that it is the sole responsibility of the operator to ensure that during remote control
operations the path of travel of the lift is visible to the user at all times.
6.2 Controls fitted to the lift unit
6.2.1 Operation by remote controls
For further information regarding both the lift mounted and remote controls please refer to:
Chapter 2.1:Views of Operating Controls and Chapter 2.3:List of parts and controls.
The following controls can be found on all the remote-control units (external controls):
a) Push buttons to control UP and DOWN function (Pages 6-7, Pos. 1 & 2)
b) Push buttons to control platform OPEN and CLOSE functions (Pages 6-7, Pos. 5 & 6)
6.2.2 Controls mounted directly on the lift unit
The following controls are mounted directly on the lift unit (internal controls):

Page 16 Version 2.08 Operating Manual PLK8
6.4 Access to lift platform
The operation of the platform lift, its access ramps and safety bars are fully automated (electro-mechanical)
and occurs as follows:
LIFT LOCATION: Lower station
Push and hold platform OPEN button
The platform folds down, and both safety bars open to vertical position.
LIFT LOCATION: Upper station
Push and hold platform OPEN button
The platform is lowered into the open position and the safety bars move into the following positions:
The upstairs safety bar opens to a vertical position; the downstairs safety bar stops in a horizontal position.
Keep the button pressed until the platform automatically stops.
Do not load the platform until it is fully opened!
Before opening the platform, make sure that there are no objects lying either on the floor or in
the near vicinity which will restrict operation!
6.5 Travelling with the stair lift
LIFT LOCATION: Lower station
Push and hold TRAVEL UP button.
Both safety bars are lowered into horizontal position, the ramps are raised and the lift travels upstairs.
Once the lift has reached the upper station continue to hold the button pressed until the upstairs safety bar
has been raised to the vertical position and the access ramp has been completely lowered.
The passenger may now move onto the platform.
LIFT LOCATION: Upper station
Push and hold TRAVEL DOWN button.
The upstairs safety bar is lowered into horizontal position, the upstairs ramp is raised and the lift travels
downstairs.
Once the lift has reached the lower station continue to hold the button pressed until both safety bars have
been raised to their vertical positions and the access ramps have completely opened.
As soon as the travel sequence is complete, release the button and the passenger may leave the platform.
6.6 Moving the lift into parked position
VERY IMPORTANT! - The operator must ensure that there are no objects left on the platform and
that the folding seat (if fitted) is first properly stowed before closing the platform with the
handheld remote control.
LOCATION: upper or lower station
Push and hold platform CLOSE button.
Both safety bars swing down and the platform folds away into the parking position.
Operating Manual PLK8 Version 2.08 Page 17
To allow the maximum amount of clearance and thereby the greatest access to the stairs and to
the upper travel rail, which can be also used as handrail, it’s recommended that the lift is parked
downstairs as often as possible.
6.7 What should I do in the case of an unforeseen stoppage?
In the event of the lift stopping, please remain calm and do not panic!
You are not in any danger and nothing untoward can happen to you.
Summon assistance by pushing the emergency call button.
We nonetheless recommend that all users carry a cordless or cellular phone with them at all times.
For further information’s regarding the emergency call options, please refer to Chapter 9.1 in this manual.
6.7.1 Emergency travel
Following a technical fault, it is still possible to move the Ascendor platform stair lift into a safe position.
PLEASE NOTE:
The following emergency travel operation procedure is only to be used in the event of a true emergency!
The lift, with a passenger onboard is positioned between stations and refuses to function and no other
possibility remains to set the lift in motion.
We would like to make the operator / user aware that during emergency travel all the safety features of the
lift will no longer function!
Emergency travel operations should only be undertaken by trained personnel!
(i.e.: the “Lift Attendant”, see Chapter 3.2.4).
Please follow this procedure to move the lift in an emergency:
Push and hold both the Emergency-Travel-Button and either
the UP or DOWN button (on the remote or onboard control
panel). The lift will move very slowly in the desired direction.
NOTE:
The Emergency-Travel-Button is located at the rear of the lift,
on the lower (i.e. downstairs facing) side of the unit, between
the crush protection panel and vertical brush strip.
WARNING: There is an Increased risk of entanglement and crushing!
Please take all possible precautions to prevent accidents and injury!
We recommend moving the lift in the direction of the next nearest station.
Upon reaching the station, the lift should under no circumstances be used again.
Please inform your Ascendor service partner immediately!
During the emergency travel operation, the emergency limit switches, emergency brake and
safety switches for the safety bars are no longer in operation. Please take extra care and
attention especially when bringing the lift into its final position in the station.
ATTENTION: After the release of the emergency brake, the lift may only be moved in the
direction of the upper station!
Possible causes of breakdown or operational stoppage:
•Excessive speed causes release of emergency brake.
•Icing up of the platform motor (by outdoor installation).
For further information refer to Chapter 11 –“Trouble Shooting Guide”.
Page 18 Version 2.08 Operating Manual PLK8
6.7.2 Emergency rescue procedure
If the lift refuses to move with the assistance of the emergency-travel-button, an emergency rescue must be
carried out. Please take the following steps:
•To free the passenger from the lift, the frictional resistance between the safety bars and safety bar motor
must be overcome manually - with the use of force.
•Open the safety bar until it is in a vertical position. Please note that the access ramp is mechanically
connected to the safety bar and it will open when the safety bar is raised.
•The passenger can now be assisted in leaving the lift on the upstairs side of the lift.
The emergency rescue procedure may only be carried out by trained personnel!
(i.e.: The Lift Attendant see Chapter 3.2.4).
Do not underestimate the risks involved when carrying out an emergency rescue!
(Injuries due to uncontrolled movement of lift, i.e.: fingers trapped or crushed in mechanism,
passenger falling from platform, etc.)
To ensure that the lift does not block access to the stairs, the platform should be folded away by hand and
secured with the tension belt provided. The tension belt has been handed over to you during installation,
together with the operating manual.
Ensure tension belt is threaded
up over the top of the safety bar
Insert the tension belt between platform
and threaded rod at the bottom of the lift.
Pay particular attention when tightening
the belt not to scratch the lift surface!
Where a front mounted access ramp is fitted,
pass the belt over the top edge of the ramp.
! ATTENTION ! - Sudden opening of the platform!
When the tension belt is removed the platform will fold down suddenly under its own weight.
Operating Manual PLK8 Version 2.08 Page 19
7. Electrical operation and recharging advice
To guarantee the long term faultless operation of the platform lift, following either a prolonged recharging
period or in the event of a lengthy power failure (more than 12 hours), switch off the lift and disconnect it
from the power supply.
Proceed as follows:
•Unplug the recharger unit from the power supply.
•If the recharger is installed in a wall mounted box, disconnect it from the power supply.
•IMPORTANT: press the UP or DOWN button shortly to stop the internal charging process.
•Now turn off the lift by the main switch located under the service access hatch (see Chapter 2.4).
This procedure must be strictly observed, otherwise internal leakage currents will drain the batteries.
The general recommendation is that the lift should remain permanently connected to the recharger to ensure
optimal recharging and ensure a long lifespan of the batteries.
7.1 Automatic deactivation
If the lift is not adequately recharged, it will automatically deactivate itself after maximum 10 hours, to avoid a
deep discharge of the batteries. Before deactivation of the lift occurs, an acoustical signal will sound and a
message is visible in the display.
To restart the lift the operator must press the RESET button (see Chapter 2.4) to return the lift to operation.
7.2 Recharging unit
The lift is supplied with a battery charger of the type “Soneil 2403SRL”.
This has a charging voltage of 24V DC and a nominal power of 48W.
The mains voltage supply must be between 90V –264V AC and the supply frequency
must be between 47 –63Hz.
This unit has been chosen because it has a wide input tolerance range and is
therefore suitable for use in almost every part of the world.
7.3 Recharging cycle
The charging cycle is split into 3 stages:
1) Recharging mode for deep discharged batteries: LED flashes
The recharging process begins with weak 0.5 V to 5 V voltage pulses. This has the effect of removing
the loose sulfation that has formed during deep discharge
2) Standard recharging mode: LED is orange
The recharger switches to a constant current of 2 A until the batteries are fully charged and have
reached a voltage of 28,8V.
3) Standby recharging mode: LED is green
The battery voltage is maintained at a constant 27,6V and the charge current slowly drops to zero.
The recharger can therefore always remain connected without damaging the batteries.
If the battery voltage should drop below 27,6 V the recharging cycle will repeat stages 2 and 3.

8. Safety features
8.1 Safety bars and access ramps
The safety bars and access ramps (see Chapter 2.2, “Views of Platform Lift”–Pos. 9, 12 & 13) are designed to
prevent people from falling off of the platform during normal operations.
8.2 Arresting device
The arresting device (see Chapter 2.2 –Pos. 17) guarantees that in the event of a mechanical or electrical
failure, uncontrolled movement of the lift down the travel rail is not possible.
8.3 Pressure sensitive contact panel (floor tray)
The contact tray (see Chapter 2.2 –Pos. 15) guarantees security against collision (along with the contact
sensors fitted to the ramps) with obstructions while traveling in the downstairs direction.
8.4 Contact sensor on access ramps
Contact sensors are fitted to the access ramps. Contact with any obstructions in the path of travel will result in
the lift coming to an immediate stop. Only the sensors in direction of travel are active at any one time.
8.5 Crush (entrapment) protection sensor panels
The two vertical panels mounted on the rear of the lift (see Chapter 2.2 - Pos. 19) guarantee safety when the
lift negotiates corners and ensure that neither people nor foreign objects can get trapped between the lift and
the hand or drive rails as the lift swings through the curved section of its travel route.
8.6 Contact sensor strip for shearing points
This contact sensor strip (see Chapter 2.2 –Pos. 20) is mounted along the top edge of the lift and is fitted
when shearing points, e.g. window sills, are located along the travel route. It is designed to prevent persons or
objects accidently becoming jammed between the lift and obstacles while the lift is moving upstairs.
8.7 Emergency stop button
If the emergency stop button is pressed (see Chapter 2.1 “Operating Controls” Pos. 3) the lift will come to an
immediate stop and an acoustic signal will be emitted.
To release the emergency-stop button simply turn it to the left.
8.8 Emergency call via acoustic signal
Pressing the emergency call button on the lift (see Chapter 2.1 - Pos. 4) will sound an acoustic signal.
8.9 Brush strip as intrusion protection
These vertically mounted brushes (see Chapter 2.2 –Pos.23) are designed to prevent intrusion of foreign
objects when the lift is in motion. Please note that they are NOT connected to sensors and always ensure the
travel route is free from obstructions before commencing travel!
