3.3 Structure
The ULVT safety light barriers consist of two components: The light
transmitter and receiver. The distance between the two components and
the installation height are calculated from the width and height of the
protective field (Fig. 8/1).

Due to its modular structure, protective field heights between 100 mm and
1900 mm can be attained (Table 8/1). Special sizes can be implemented
for installation-dependent dimensions.
The transmitter and receiver and synchronous, i.e., at any one time, only
one light beam and one receiving element are active. Synchronization is
implemented by the first light beam and first receiving element. An electric
connection between the transmitter and receiver is therefore not required.

3.4 Function
The transmitter generates infrared light beams which are switched on an
off in quick succession. The parallel light beams at a distance of 7.5 mm
are assessed by two single-chip microcontrollers. The beam distance
produces a definition of 14 mm.

If an object is located within the protective field, i.e., at least one of the
light beams is blacked out, the two outputs of the receiver will stop the
hazardous movement of the machine and/or prevent a start. In the
operating mode with restart interlock, the machine can only be restarted
by actuating the start button when the protective field is free again.

3.5 LED displays
Several LEDs on the receiver indicate the current operating status (Fig.
8/3). If the system test detects an internal or external fault, the machine
will be switched off immediately and the LEDs on the transmitter and/or
receiver indicate the fault status to the user.
Self-diagnostics system: A fault diagnostics program is available for
trained service personnel. This program provides precise and on-site
localization of the fault. When a fault is present, the flashing LEDs together
with a fault code provide visual output of the detected fault and display in
the diagnostics device.
