Reusing lifts (rail only projects)
Freelift units are universal for inside and outside curves, both left-hand and right hand. They are consequently ideally suitable for reuse.
When curved stairlifts were first introduced (2000) a few modifications were made, as a result of which these units can only be used in certain situations.
When placing an order for a "rail only" project please specify which unit you plan to reuse. The article number is marked on the sticker on the side of the unit.
It is important to note that the Freecurve 2 unit, for example, cannot be used on a rail with an inside curve.
Initially, 32 and 48 pulse data cards were supplied. We later switched to the so-called V3 cards, which we still supply today.
The printed circuti is the electronic centre of the chairlift and positioned in the unit. There are different types of prints
The FCC1-F8/A1 WI D3/K6
The FCCI -F8/A1/W1/D3/K6 prints function only with traction motors with a 32 puls encoder.
The FCCI -F8/A1/W1/D3/K6 prints function only with mechanic tilts witches C3020000.
The FCCI -F8/A1/W1/D3/K6 prints function only with the wall buttons 433 MHZ
Appropriate grounding measures must be taken when handling the prints because of electrostatic discharge of the components damaging the printed circuit. Loose prints should be transported solely in ESD-proof packaging
A red LED on the print illuminates once the power is connected to the print..
A retro cable for the chair motor is required. Consequently this cable should be removed when fitting a J4 print to a chair lift which was originally fitted with a K6 print
Print FCC1-J4/H4/T2
The print is complete retro fit table with the FCCI -F8/A1/W1/D3/K6 and consequently has the same article number: Cl 0001502
Modifications in comparison with the FCCI -F8/A1 /W1/D3/K6:
The output 24V= voltage is provided with a self-resetting fuse in the event of short circuits between the safety line and the frame.
This protects the control system in the event of a short-circuit in the safety line.
The self-resetting fuse cannot be replaced. The red test button has no function.
Print FCC2-S5/N5
Print FCC2-S5/N5 has been fitted since February 2002.
This print is not interchangeable with its predecessors, and has consequently been assigned a different article number.(C1001520)
The printed circuit FCC2 is only appropriate for motors with 32 pulse encoders. The printed circuit FCC2 can be upgrade, so it is also suitable for 48 pulse encoders. The name will be changed to FCC3.
The printed circuit FCC2 functions together with the tilt switches C3020000.
The printed circuit FCC2 functions with the wall buttons 433 MHz article number
C1001400.
The FCC2 can in any case be replaced by a printed circuit FCC3
The FCC3 PCB
The FCC3 PCB is similar to the FCC2 PCB but suitable for motors with 48-pulse and 32-pulse encoders.
The FCC2 PCB can be upgraded to make it suitable for 48-pulse encoders. If this is done, their designation will be changed to FCC3.
FCCI PCB's shall always be suitable for motors with 32-pulse encoders. The FCC3 printed circuit functions with the tilt switch C3020030.
The FCC3 printed circuit functions with the wall buttons 433 MHz article number C1001400.
When a FCN3 printed circuit is to be changed by a FCC3 printed circuit, also the tilt switch and wall buttons have to be replaced. On the tilt switch cable you mount a short-circuit.
The FCN3/5/6
The FCN3/5/6 printed circuit is valid for motors both 32 and 48 pulse encoders.
The FCN3/5/6 printed circuit functions with the tilt switches C3020010.
The FCN3/5/6 printed circuit functions with the wall buttons 866 MHZ C1001410.
When a FCN3/5/6 printed circuit is replaced by a FCC3 printed circuit, also the tilt switch and the wall buttons shall be replaced.
The short circuit connector at the tilt switch shall be removed.
C1001513 FCN6
The C1001513 has a longer reach for the remotes. This has caused a number of changes in the article numbers:
| OLD | NEW |
Printed circuit | C1001512 | C1001513 |
Wall button | C1001410 | C1001413 |
Hand button | C1001450 | C1001453 |
When changing a unit or printed circuit, and the article number of the printed circuit changes, it is necessary to change the wall buttons too.
The article numbers are noted on the printed circuit and the wall buttons.
With this printed circuit it is possible to run away from the foldable rail point, even if the foldable rail motor is not detected. So the user never can get stuck on the staircase.
C1001514 FCN 6
The printed circuit C1001514 has no soft stop and is installed in units C0020055 for projects without dropnose.
Instruction for reading the printed circuit FCN3 FCN5/FCN6
To learn more about the failure, the memory of the printed circuit can be stored on an empty datacard.
Follow the next steps:
Switch the key switch in the position "0" and remove the key.
Remove the cover.
When the fuse has blown, replace the fuse first.
Don't disconnect the batteries.
Turn away the chair, so the card reader is reachable.
Put the empty data card in the card reader of the pcb.
Wait for the pcb to give 2 beeps (within 30 seconds)
Take the data card out of the card reader, note the project number on the data card and send this form with above information to the customer support department of Free lift, Newtonstraat 35, 1704 SB Heerhugowaar.
Disconnect the power of the lift.
Put the original datacard in the cardreader of the pcb.
Connect the power of the lift and horizontalise the chair
Switch the keyswitch in position "1 " and drive the unit on the calibrationpoint
Recalibrate the unit when necessary.
Mount the cover.

The tilt switch
The tilt switch has been included in the general safety lines and it interrupts the safety line if the chair tilts 5 degrees with respect to the horizon.
Mechanical tilt switch C3020000
The mechanical tilt switch is fixed on the chair. This tilt switch functions with the following PCB's:
All FCCI PCB's.
The articlenumber is C3020000.
The electronic tilt switch
The electronic tilt switch is fixed on the unit.
This tilt switch works with all FCC2 and FCC3 printed circuits. This tiltswitch is only used in combination with the wallbuttons on 433 MHZ 433 MHZ (Cl OOI 400).
The articlenumber of the tiltswitch is is C3020030.
A grey cable is connected to the tilt switch; this is the general safety line. A black telephone cable is connected to the tilt switch; this is a control line. There is a green control lamp on the tilt switch.
The green control lamp will light up briefly when the telephone cable is connected. It will continue to be lighted when the tilt switch is activated.
When the chair lift is at the end of the rail, the PCB will check the tilt switch. The lamp lights up briefly during the checking.
If the telephone cable is not connected, the chair lift will make one trip, and at the end of travel, the PCB will detect the absence of a signal and the chair lift will not move thereafter.
The green lamp on the tilt switch will not light up.
If the safety line is interrupted because the tilt switch comes into operation or because the grey cable has come loose, the chair lift will not move. The lamp in armrest will flash continuously.
When the tilt switch lights up, the telephone cable should be disconnected before the chair can be operated with the calibration switches "1 " and "2'
Electronic tiltswitch C3020010
The electronic tilt switch is fixed on the unit.
This tilt switch works with all FCN PCB's.
