A light beam for the highest safety level
The light beam is available in two versions Spot 10 for
distances up to 10 m and Spot 35 for up to 35 m . The
light beams can be mounted at different heights and be
angled around a machine using our mirrors and brackets.
Spot and Vital/Pluto in combination fulfils the requirements
for PL e according to EN ISO 13849-1 and type 4 according
to EN 61496. Several light beams, Eden sensors and
emergency stops can be connected in series achieving the
high safety level for the safety circuit. A number of solutions
for bypassing of light beams for material transport are available.
For indication there are LED´s on the transmitter and on the
receiver which indicate ’contact’ between transmitter and receiver
and safety status. The ’contact’ information is available via the light
beam receiver connection cables.

- safety light beams
Function
The Spot light beam is supervised by the Vital safety controller
or by the Pluto safety-PLC. A unique coded signal is sent out
from the control unit to the transmitter (Spot T). The signal which
comes back from the receiver (Spot R) is then compared in
the Vital/Pluto. If the correct coded signal is received the Vital/
Pluto switches the necessary safety output contacts to permit
dangerous machine movements. Coding guarantees that no
output signals can be produced by light from other sources,
interference or faults in components in the transmitter or receiver.
The light beam is dynamically supervised which means that if the
signal stops pulsating at the correct frequency it is immediately
detected. By means of coding, the dynamic signal can pass
between up to 6 pairs of transmitters and receivers, with only one
pair needing to be electrically connected to a Vital.
