Considerations
• The muting function is allowed to be activated only when transporting a material to the hazardous area.
• The muting function should be triggered by at least two independently wired signals (which are received from muting
sensors) and should not depend entirely on software signals (from a programmable controller).
• After a material has been transported to the hazardous area, the safety device should be immediately enabled.
• The material to be transported must be detected by muting sensors over its entire length and there must be no interruption
during the transportation.
• Always position sensors so that the minimum distance to the protective equipment is observed. For details on the minimum
distance, refer to the following:

Page 106 Minimum distance to the light beams on the ESPE
• To prevent unintentional triggering of the muting function by a person, install sensors in the appropriate position.
• The outputs on the muting sensors should be OFF when powering an FX5-SF-MU4T5; otherwise, an error occurs.
• The duration of the muting function is indefinite.
• A muting lamp turns ON continuously, then muting is active.
• A muting lamp flashes at 1 Hz, then the reset request is enabled.
• Always install a muting lamp where it can be clearly seen. A muting lamp must be clearly visible from all sides of the
hazardous area and for the system operator.
(1) Ensure the sensors installed in both sides are not activated simultaneously.
(2) Ensure the adjacent sensors are not activated simultaneously.
