2 Overview
General description
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 ABB/Jokab Safety mirrors and
brackets.
The combination of Spot and Vital 1 fulfils the requirements for Category 4/PL e according to EN 954-1/EN ISO
13849 and type 4 according to EN 61496. Several light beams, Eden sensors and emergency stops can be
connected in series and still achieve PL e for the safety circuit. A number of solutions for bypassing of light beams
for material transport are available.
For indication there are LEDs on the transmitter and on the receiver which indicate ’contact’ between transmitter
and receiver, as well as the safety status. The ’contact’ information is available via the light beam receiver
connection cables.
Shielded cable is recommended between this unit and the rest of the safety circuits.
Intended use
The safety light beam Spot 10/35 is intended for use as part of a safety system to detect persons entering a
hazardous area. Safe signals are supplied to the control unit (Vital 1) that is controlling the safety outputs.
Warning!
Spot 10/35 is not to be compiled as a light curtain to detect fingers or hands.
