Design and function
ULCT/BLCT safety light curtains each comprise two
components: Light transmitter and light receiver.
The clearance between these two components and the
installation height determine the width and height of the
protective field
(Figure 5/1).
Modular design permits realization of protective field
heights ranging from 100 mm to 1500 mm in 100-mm
steps.
The transmitter generates infrared light beams in rapid
pulses. These parallel light beams are analyzed by two
single-chip controllers in the transmitter. The beam
spacing determines the resolution (refer to Table 5/2).
If an object enters the protective field, i.e. if at least one
light beam is interrupted, the receiver's two outputs stop
the machine or prevent it from starting, thus avoiding
hazards.
In the restart with interlock operating mode, the machine
can only be restarted by means of the start button once
the protective field has been cleared again.

Outputs (OSSDs) active ................ green LED comes on when the outputs are energized.
Outputs (OSSDs) inactive .............. red LED comes on when the outputs are de-energized.
-Indication of operating mode ...... for about 2 seconds during power-on.
-Indication of the uppermost ........ see below
interrupted light
-Error diagnosis............................ refer to the chapter on error diagnosis
Adjustment aid and light reserves .. red LED comes on when light reserves have dropped.
Restart interlock ............................ in the operating mode with restart interlock, the yellow
LED comes on when the protective field is clear and
the start button is ready for operation.
The LEDs and display on the receiver indicate the current operating status.
Display on interruption of a light beam
If one or more light beams are interrupted, the number of the
uppermost interrupted beam (as seen from the connecting plug) is
displayed.
On light grids comprising more than 99 light beams, the right-hand
decimal point also shines if the 122nd beam is interrupted, for
instance. If a light beam numbered higher than 200 is interrupted,
both decimal points shine.
If the synchronous eye is interrupted (1st light beam as seen from
the connecting plug), "0 0" flashes on the display.
23rd light beam is
interrupted.
122nd light beam is
interrupted.
1st light beam is
interrupted.

1System description 1.5 Indication and change of operating mode
Changing the operating mode
To change the operating mode you have to disconnect the power supply. Then bridge the OSSD2 (6) output with
+UB (2) input and connect a button between the Start (1) input and +UB (2) input .
6 / pink: OSSD2 2 / brown: +UB
1 / white: Start
The button at the Start input must be actuated during power-on.
"L L" flashes on the display.
The button at the Start input must remains on (min. 2s),until the actual
operating mode from the device flashes on the display. You can then
release the button.
To select a new operating mode, briefly press the button once again; the
selected mode flashes on the display. Each time you shortly press the
button, the next operating mode is called up.
If you hold down the button for 2 seconds or longer, the currently displayed
operating mode is saved and remains solidly lit on the display.
This procedure (brief actuation of the button) can be repeated as often as necessary. After you
have removed the bridge between OSSD2 and +UB and reset the voltage, the saved operating
mode becomes effective.
Indication of operating mode
The stored operating mode is indicated for about 2 seconds during power-on.
"E A" = with EDM (contactor control) / with restart interlock (setting on delivery)
"E -" = with EDM (contactor control) / without restart interlock
"- A" = without EDM (contactor control) / with restart interlock
"- -" = without EDM (contactor control) / without restart interlock

1System description 1.6 Fault diagnosis
Fault diagnosis
If the light grid detects a faulty connection or an internal error, the adjustment-aid and restart-interlock LEDs
flash together with the corresponding error code on the display.
F1 = Incorrect start line
Operating mode with restart interlock: Start input is bridged to +24 VDC.
Operating mode without restart interlock: Bridge from start input to +24 VDC is missing.
F2 = Incorrect EDM line
Operating mode with EDM: The contactors are not released or
the EDM input is bridged to +24 VDC.
Operating mode without EDM: Bridge from EDM input to +24 VDC is missing.
F3 = External transmitter detected
A second light transmitter has been detected in the receiver's range. To preclude mutual
interference between adjacent light curtains, neighbouring systems must be installed in
accordance with the instructions on Page 16.
F4 = Error during change of operating mode
The start button was held down too briefly for changing the operating mode during
power-on. Or the bridge from OSSD2 to +24 VDC was detached during a change of
operating mode (refer to the section on changing operating modes on Page 7).
F5 = Internal error
Power-on the device once again. If F5 is still displayed, an internal error has occurred.
In this case, the device must be sent in for repair.
No start possible despite clear light path (display off):
In the operating mode with restart interlock, if the yellow LED does not shine despite intact
light beams and the adjustment aid LED is off, it means that the contactors are not released.
Flashing:
1st light beam is interrupted.
Not flashing:
No blanking (only for BLCT)

E L E K T R O N I K
F6 = OSSD error
Short-circuit between one or both OSSDs and +24V, or between the OSSDs.
