Door blanking (SB2)

The GridScan/Mini-SB2 can differentiate between a light
beam interruption caused by an object and a light beam
interruption caused by the closing door. The GridScan/
Mini-SB2 does this by analyzing the different interruption
patterns.
Closing door interruption pattern:
The light beam interruption of a closing door starts at the
topmost beam going downwards.

Installation

WARNING
Electrical and mechanical hazards
Electrical shock
movement can cause serious injury or death.
 Follow all applicable safety measures.
 Use only specific and approved tools.
 If the GridScan/Mini-SB2/-ST2 must be
adjusted, the main power supply must be
switched off and marked as out of service.
1. Switch off main power to the door control unit and mark clearly that this system is out
of service before performing any work on the system.
2. SB2: Mount the receiver edge into the guiding rail next to the door control unit.
Important for SB2:
In order to fulfill EN 12978:2003 +A1:2009 the lower end of the edges have to
be at the level of the door closed position.
SB2: Mount the receiver edge on one side of the door.
3. Mount the emitter edge across from the receiver edge. If the receiver is mounted
in the guiding rail the emitter should be mounted in the guiding rail opposite the
receiver. Make sure the optical elements are facing each other (Chapter 5.3).
4. Connect the emitter with the receiver edge using the synchronization cable.
5. Plug the connection cable into the blue plug on the receiver edge and connect it
to the door controller (Chapter 8).

and unexpected door
When the GridScan/Mini-SB2 is integrated into the guide
rail, the door moves directly in front of the light curtain. If
the light curtain is located either in front of or behind the
guide rail, the descending door will not interrupt the active
beams. However, blanking may still be required if any part
of the door (e.g. cable) interrupts the light curtain. For a
successfull blanking, either by the lower door edge or a
beamblocker at least one element needs to be continuously
covered during door closure (Figure 9).
NOTICE
Mechanical damage to the
GridScan/Mini-SB2/-ST2
 Do not drill additional holes into the light
curtain.
 Do not overtighten the mounting screws.
 Mount the edges on a flat surface.
