2. For Your Safety
2.1 Use for Intended Purpose
The product is based on the following functional principle:
Safety light arrays
The light array monitors the safety field between the transmitter and the receiver. If the safety field is penetrat-
ed by an object, a switching command is triggered. This switching command may prevent initialization of a
hazardous machine motion, or may stop an action which has already been started.
As part of an overall system, the task of this product is to carry out safety-related functions. The correct over-
all function must be ensured by the system or machine manufacturer, however.
Use of this ESPE is only permissible if:
• The hazardous motion can be stopped electrically by the safety outputs of the ESPE.
• The safety clearance between the ESPE and a hazardous machine motion is complied with at all times.
• Additional mechanical safety equipment is installed so that the safety field must be passed through to
access hazardous machine parts.
• Care is taken during installation to ensure that the personnel always remain inside the monitored zone for
machine operation.
• Regular safety inspections are carried out.
• Adequate detection of possible obstructions is assured with the existing number of beams.
• The use of a light array, type 4 / Performance Level PL e / SIL 3 / SIL CL 3, was deemed permissible follow-
ing an extensive risk analysis.
