0. General
0.1 Intended use
The railoc electrical safety space is used for the automatic creation of safety spaces and
clearances on the car roof (see EN81-20 Item 5.2.5.7) and/or in the shaft pit (see EN81-20 Item
5.2.5.8) if these are not available naturally due to the geometry of the building structure and/or
the nature of the lift installation.
0.2 Preliminary remark
These instructions refer to the installation, maintenance and operation of the railoc electrical
safety space.
railoc has a type approval (LIFTINSTITUUT, certificate no. NL17-400-1002-246-01). Within the
framework of this type examination, the suitability of railoc for the automatic creation of
temporary shelters as well as the associated safety concept was examined and proven..
0.3 Liability and warranty
railoc is only to be used in a technically perfect condition - in compliance with these instructions
- in accordance with the intended use, safety and risk awareness.
In the event of improper use or manipulation of the railoc, the type examination certificate of the
Liftinstituut and any claims with regard to guarantee and/or liability towards the Liftinstituut and
the manufacturer of the railoc expire.
Non-observance of these instructions and unauthorised use can cause danger to
property and persons!
0.4 Safety Instructions
The safety of the railoc fitter is to be guaranteed on his own responsibility. The basic
professional qualification of the person is assumed.
These instructions must always be followed to avoid damage and injury to persons involved and
the device.

The operating instructions are part of the certified machine and must always be available on site!
1. Device description
1.1 Design and scope of deliver
Main unit:
Pawl with drive on vertically movable carriage, support console with two energy-consuming
cellular foam buffers Ø100x80 which are connected to the guide rail by means of clips and
notched pins in a non-positive and positive-locking manner.
Incl. 2 types of clips, grooved pins, drilling template and pre-assembled connection cables (10m).
Signal lamp, red/ green:
Indicator light for optical visualisation of the protected area protection status (red=protected area
unsafe; green=protected area safe) in a separate housing with magnet on the back for clearly
visible fastening in the shaft, pre-assembled with the main unit on 10m cable (extendable).
Standard stops for car and counterweight:
One stop each for car and counterweight, which can be screwed under commercially available
guide shoes.
Optional accessories:
 Extension cable for indicator light, 10m. With connection coupling for connecting several
extension cables.
 Inspection switch with spring finger as actuation, mountable on the main unit. Swivels via a
linkage, when the railoc is activated, into the projection of the travel range and stops the travel
before the stop hits the railoc.

Assembly and maintenance instructions railoc
1.2 Functionality
The general function of the railoc, independent of its position in the shaft, is described below:
 railoc is mounted according to these instructions and connected to the lift controller.
 If a landing door is opened manually in order to enter the car roof or shaft pit, the additional
contact on the emergency release of this door is activated (NC contact).
 The circuit to the input of a safety relay is interrupted by the normally closed contact.
 The safety relay switches, the 24V supply voltage from the railoc actuator drops out.
 The railoc actuator extends the pawl mechanically via spring force, into the travel path of
the car or counterweight.
 The travel path is blocked, the protective space is mechanically secured (red light=off /
green light =on).
 The system can now only be moved in inspection mode, an inspection limit switch stops the
inspection travel approx. 50cm before reaching the pawl.
 After finishing the work in the lift shaft and closing the shaft door, the lift system is RESET.
 The safety relay switches, the railoc actuator is energised and moves the pawl to the rest
position by motor.
 The elevator is now back in normal operation.
The car or counterweight must not be placed on the railoc not even for test
purposes. The railoc represents a mechanical stop for emergencies -
components involved can be damaged when the car or counterweight is placed
on the railoc!

8/21
Assembly and maintenance instructions railoc
1.3 Mounting variants
For overhead mounting, the following must be ensured
that the rail track is protected against lift-off
is secured by the bottom of the pit!
The railoc is compatible with all commercially available solid profile rail types with back
dimensions of min. 45mm up to ≤90mm!
The railoc can be used both on the guide rail of the
car and on that of the counterweight. In addition, the
design allows overhead installation, i.e. the car or
counterweight can also be limited in their respective
upward travel path.
Protective space above: red positions
Under the counterweight
Above the car
Lower shelter: green positions
Under the car
Above the counterweight

1.4 External components and boundary conditions
Die Montage einer railoc an sich bildet kein ausreichendes Sicherheitskonzept. Es sind weitere
Komponenten bzw. Maßnahmen erforderlich um ein prüffähiges Sicherheitskonzept zu
erlangen, die kundenseitig bereitgestellt werden müssen. Die nachfolgend aufgeführten
Komponenten beziehen sich auf die im Anhang befindliche (Beispiel-)Gefahrenanalyse. Andere
Varianten sind denkbar, müssen aber im Vorwege mit der ZÜS geklärt werden.
Safety relay:
The railoc must be controlled via a safe relay
(SIL3). Suitable for this purpose are for example:
Schmersal, SRB301 S
Reset unit:
The tripped safety relay must be reset by means of
a button with removable actuation, e.g. key
Emergency unlocking monitoring:
The opening of a landing door via the emergency
unlocking device must be detected by the system
without any doubt. Actuation of this function results
in the activation of the railoc.
Inspection limit switch (optional):
The inspection limit switch limits the travel path in
safe condition and interrupts the inspection travel
before hitting the railoc.

10/21
Assembly and maintenance instructions railoc
Boundary conditions for the use of railoc
 The sum of cabin weight (P) and load capacity (Q) must not exceed 2500kg.
 The nominal speed must not exceed 1.0m/s.
 A sufficiently mechanically stable stop on the car or counterweight must be provided. (2
standard solutions are included in the scope of delivery).
 If the railoc is installed overhead, the rail track must be secured in its Z-axis against lifting.
Example solutions: Angle at rail foot and pit bottom, support against the shaft ceiling, etc.
 It must be ensured that the adjoining building interfaces have sufficient strength => shaft
ceiling, pit bottom.
 railoc is not permitted for hollow rails.
1.5 General notes on function
 railoc is always energised in normal operation!
 The red indicator light is only active from the time the landing door is opened to a safe
condition.
 The railoc is only activated after a safety relay has been triggered and is only deactivated
when the relay is reset.
 If the car is at one of the final stops, the railoc must not extend.

2. Assembly/ installation
2.1 Preparation
Ensure that the car frame or counterweight has a sufficiently strong mechanical stop at the
lower or upper end in its projection that would withstand the forces of an impact. The support at
the stop should project at least 10 mm into the projection of the extended pawl! In addition, the
minimum distance to moving parts should not be less than 15mm when retracted. The following
figure shows the railoc`s extension range in its horizontal projection.

Retracted

12/21
Assembly and maintenance instructions railoc
The railoc must be mounted during the installation process in such a way that
the necessary protective space for the fitters (provisionally) is always guaranteed.
2.2 Positioning the railoc
In accordance with the dimensional specifications in the preceding illustration, the mounting
height of the railoc must be selected so that the requirements for protective spaces and
clearances according to EN 81-20, 5.2.5.7+8 are met for your system.
The reduction of the latch height due to the maximum buffer stroke (72mm) must be added
when calculating the dimension for the mounting height.
It is recommended that the mounting height is selected so that after placing the door on the
railoc there is a clear gap of 300mm between the door opening and the upper edge of the door
header or lower edge of the apron. This ensures an escape route for the installer in an
emergency.
2.3 Mechanical assembly
 After calculating the required mounting height, mark the position of the lower edge of the
railoc on the corresponding rail.
 Depending on the width of the rail spine, either the A14 or the A11.5 clips are ready, see
figure.
 Hold the railoc by the back of the rail and fix it roughly in position on the rail with a standard
screw clamp.
 Mount the clips and tighten them slightly.
 Align the position exactly in the middle using the markings on the back of the railoc.
 Tighten the clips with a torque wrench. A14: 81Nm, A11.5: 47Nm
 Check whether there is an air gap on both sides between the latch and the back of the rail
and check the mounting height again.
 Use a 10.2 mm twist drill to drill through the holes in the base of the railoc into the rail. If
there is no space for drilling at the back, use the template provided and drill from the front
of the railoc.
 From the base side, drive the dowel pins into the holes.
 Position the signal lamp so that it is clearly visible from the area in which the temporary
shelter is created.

13/21
Assembly and maintenance instructions railoc
2.4 Electrical installation
The railoc is internally pre-wired so that only the two or three plug connections have to be
joined together on the device, with optional inspection limit switch.
Pre-assembled cable extensions are available in 10m lengths.
 Switch the system off by operating the main switch
 Uncoil the associated supply cables and lay them, starting at the controller
 Ensure that the cable routing is clean, which minimizes the risk of damage to the cables.
Use loop dowels or cable duct.
 If necessary, extend the cables until you reach the railoc
 Connect the two or three plug connections
 Go to the controller and lay the pre-assembled ends of the cables to the terminal block
area in the controller
 Using the railoc circuit diagram in the appendix, connect the individual wires to the
corresponding terminal blocks according to the specifications of your control
manufacturer
 Ensure that the wiring has been carried out correctly.

14/21
Assembly and maintenance instructions railoc
2.5 Inspection and commissioning of the system after installation.
Leave your temporary protection of the protective space in the shaft until you are
explicitly requested to remove it by the drain!
 Switch on the voltage to the system.
 The railoc remains extended and the green light signals safe status.
 Approach the railoc with the car or counterweight during inspection travel and stop
approx. 1m in front.
 Check that the inspection limit switch is operated reliably when driving on.
 Check by measuring that the latch of the railoc actually hits the stop provided for this
purpose on the car or counterweight.
 Also check that the stop can pass the latch in the retracted position without colliding with
it.
 Now remove your temporary shelter.
 Leave the shaft and close all doors.
 Make sure that there is no one left in the shaft.
 Disable the landing calls and switch the system to normal operation. The return to
normal operation must require a RESET of the safety relay! The railoc begins to retract
after its actuation. When the process is completed, the safety contact on the railoc
finally releases normal travel.
 Issue calls to the terminal stops and check that the system runs without collisions during
normal travel.
 Go to one of the monitored landing doors and open it using the emergency release. The
signal lamp lights up red and the railoc extends. Observe the smooth running of this
process and the subsequent switching of the signal light to green.
 The temporary shelter is now established and the shaft can be entered.
 Repeat this procedure and check the proper functioning of all necessary emergency
unlocking monitors of the landing doors.
 Then carry out an inspection travel and check that the travel movement is reliably
stopped by the inspection limit switch.
 Leave the car, close the doors and switch the system back to normal operation by
pressing the RESET button.

3. railoc in operation
3.1 Test instruction
The mechanical strength of the system was tested by the Liftinstituut during the type
examination. In the course of the recurring inspection of the system, it is not necessary/
permitted to put on the car or counterweight. The pure function test is sufficient.
The railoc should protect life and limb. It is accepted that in the event of a collision with the
railoc, the components involved can be damaged by the one-sided load.
The railoc manufacturer accepts no liability for any damage to components
caused by impact.
3.2 Maintenance
The maintenance of the railoc or the entire system which represents the safety concept should
be subject to maintenance and inspection at least once a year.
The following checks must be carried out for maintenance:
 Strength of the clamp connections
 Visual inspection of the touchdown buffers
 Movability of the pawl
 Visual inspection of the compression spring
 Functionality of the control lamp
 Visual inspection of the switch below the latch
 Visual inspection of the spring finger switch (inspection limit switch)
 Cleanliness of the electrical protective space latch
Before entering the shaft, make sure that the green indicator light confirms the
"Safe" status!

Assembly and maintenance instructions railoc
3.3 Repairs and disposal
In principle, repairs to the railoc should only be carried out by qualified personnel and with
original parts. Defective statically relevant parts must be replaced.
If an unintentional impact of the counterweight or the car on the railoc, occurs, the main unit
must then be checked for damage and deformation. If damage or deformation is detected, the
railoc must be replaced!
The manufacturer is able to determine whether a collision has occurred!
If further use of the railoc is no longer possible due to a defect, it must be disposed of in an
environmentally friendly manner in accordance with national regulations.
During repairs on the railoc, the necessary protective spaces are not
guaranteed and must be ensured accordingly by other means!
