4. Introduction
The GridScan/Mini-SR is a very compact, Cat. 2 certified
light curtain designed for safeguarding the entrance area
of a freight or platform elevator. The GridScan/Mini-SR
comes in combination with a FSS Control Unit, which can
be supplied with either 24 VDC or 230 VAC and features
a relay output.
Due to an integrated automatic range setting, the
GridScan/Mini-SR can also be mounted near shiny
surfaces without any mirroring.
The emitter and receiver edge have to be mounted at the
door frame and are synchronized electrically. This leads to
increased robustness against other light sources.
The emitter and receiver edge create a dense grid of
straight and crossed infrared beams offering 1,805 mm
(6 ft) protection height. When the infrared beams are
interrupted, the output sends a signal to the connected
elevator door controller. As soon as the detection area is
clear again, the output switches to indicate that the area
is “clear”.
Figure 1: Typical GridScan/Mini-SR application environments
4.1 Features of the GridScan/Mini-SR
• Criss-cross beams
• Safety Cat. 2 without testing
• Optimized to prevent optical bypassing
• Electrical synchronization for increased light and
strobe immunity
• Relay output (direct wiring into the safety circuit)
• 24 VDC and 230 VAC version available
• Cross-section only 12 mm × 16 mm, side and front
mounting possible
• Ideal for EN 81-41 certified elevators
4.2 Delivery package
The GridScan/Mini-SR comes with a customerspecific
delivery package. A typical delivery package contains:
Figure 2: Typical GridScan/Mini-SR delivery package
• 1 × emitter edge (Tx)
• 1 × receiver edge (Rx)
• 1 × synchronization cable 3 m
• 1 × connection cable 3 m
• 1 × FSS Control Unit (either 24 VDC or 230 VAC)
• 1 × installation and operation manual

4.3 General instructions and precautions
4.4 Alignment
Never scratch or paint the optical lenses because they form the
light path! Do not drill additional holes into the profile. Unpack
the profiles just before installation in order to avoid damage.
Do not bend or twist the edges!
Oil can damage the cables. Contamination must be avoided
at all times!
Make sure to place the connection plugs for both the emitter
and receiver at the same end.
Although the GridScan/Mini-SR is insensitive to direct sunlight,
avoid all unnecessary exposure if possible, most especially to
the receiver.
Avoid interference from blinking lights or infrared light sources
such as photo cells or other light curtains.
Do not install the GridScan/Mini-SR in places where the emitter
and receiver edges are directly exposed to light sources such as
FL tubes or energy saving lamps.
TxRx RxTx
Tx Rx Tx
R
x
The optical axis of the emitter (Tx) and the receiver edge (Rx)
need to be aligned towards each other to ensure the light curtain
functions reliably.
Reflective surfaces near to or parallel to the safeguarded area can
cause reflections. Although the GridScan/Mini-SR is very robust
against such reflections, it is always advisable to keep a reasonable
distance between the sensor edges and any reflective surface.

5. Installation
It is recommended to carry out the system installation
according to the following steps:
1. Switch off main power and mark clearly that this
elevator is out of service.
2. Mount the receiver edge on one side of the door at
the door frame .
3. Mount the emitter edge across from the receiver
edge. Make sure the optical elements are facing each
other.
4. Connect the emitter and receiver edges using the
synchronization cable.
5. Mount the FSS Control Unit with two (2) screws onto
the elevator cab.
6. Plug the connection cable into the blue plug on the
receiver edge and connect it to the FSS Control Unit.
7. Connect the FSS Control Unit with the elevator door
controller.
8. Cover both screw heads with the cover caps provided
and close the cover of the FSS Control Unit.

8. Start-up
1. Switch on mains and power up the elevator.
2. Check the LED status on both edges (power, status).
3. Test the light curtain by giving a travel command
and interrupt the light curtain during journey. The
elevator must stop immediately when the light curtain
is interrupted.
Note: A minimum of two people is required to conduct
this test, one person in the cabin and one person outside
(e.g. caretaker).

11. Maintenance
Although the GridScan/Mini-SR does not need regular
maintenance, a periodical functional check is strongly
recommended as follows:
The optical sensor elements are clear of dirt and dust.
If necessary, clean the front surface with a soft towel.
The edges are securely fastened.
The cables are fixed properly.
The FSS Control Unit is securely fastened.
