= If the actuator moves laterally in relation to the surface of the sensor,
a minimum distance of 9 mm must be maintained. This distance will
prevent premature triggering due to the side approach areas.
= If necessary fit an additional protective stop for the moving part of
the guard.
= Pay attention to the maximum tightening torque for fastening the
sensor and actuator of 2.3 Nm.
Pay attention to the following safety notes:
• Sensor and actuator shall not be used as a mechanical stop.
• Prevent tampering such as adjusting, removing or bypassing the
device that will prevent correct function in any manner. The conse-
quences otherwise may be injuries or death.
• The availability of spare actuators may jeopardize the integrity of the
safety system (risk of tampering). This situation may result in injuries
or death, damage or financial losses. Organize suitable monitoring,
procedures and alternative protective measures to regulate the
usage and availability of these replacement actuators.
