Function description

The Spot light beam is supervised by the Vital 1 safety module. 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 1 safety module. If the correct coded signal is received the Vital 1 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 1.
