12.4 Light Curtain Kit
The TSG can be equipped with an additional light curtain. The light curtain consists of a transmitter and
receiver bar which monitor the door opening for obstructions. To simplify the assembly, the TSG Light Kit is
fitted with pre wired plug-in cables. Thus, the assembly time is significantly reduced.
The signals from the light curtain can either be connected to the TSG control board via the elevator control
system or directly to the TSG control board.
If the light curtain is directly attached to the TSG control board (input X1.3), parameter h3 must be configured
accordingly. The signal from the light curtain can either be set as "normally open" or "normally closed". If a
signal to open the door is sent by the light curtain to the TSG controller, it will open the door as long as the
light curtain is interrupted.
NOTE:
Once power is restored following a power failure, the TSG door operator will begin a
reference run to find its position. If the light curtain is obstructed during the reference run the
TSG will stop until the obstruction is removed.
CAUTION:
The TSG will not recognise any signal at input X1.3, when the door is in the range of the
parameter bb (capture range for door closed position, see also Table 4: b parameters, page
20).
WARNING:
If you wish to connect a light curtain directly to terminal X1.3 of the TSG door operator this
must only be done in installations where the light curtain is not relied upon to act as safety
device, for example in installations where there are no car doors.
Further information on the electrical connection and installation can also be found in the manual for the TSG
Light Kit.
