• ESPE has to be correctly aligned: press slightly on the product side in both direc-
tions, the red LED must not turn on.
• The activation on the TEST function (on TX side) causes the opening of the OSSD
outputs (red LED, OSSD on RX side, ON and controlled machine stop).
• The response time at machine STOP, including the ESPE and machine response
times, must be included in the limits defined in the calculation of the safety dis-
tance (refer to "

).
• The safety distance between the dangerous parts and ESPE must comply with the
requirements indicated in "
Minimum installation distance" on page 6
.
• A person must not access or remain between ESPE and the dangerous parts of the
machine.
• Access to the dangerous areas of the machine must not be possible from any
unprotected area.
• ESPE must not be disturbed by external light sources, ensure that it remains in
