IMPROPER INSTALLATION
• The interruption of the beams SM1 & SM2 starts the muting sequence,
but the electrical connections must be made in such a way that the release
of the protective equipment beams stops the muting sequence (refer to the
figure 4.18 of the chapter 4.9.1 Conveyor applications).
•
The distance between SM1 & SM2 beams shall not allow a person to actuate
both sensors within the preset time frame tmax, and the intersection between beams
must be located inside the dangerous area to avoid the unexpected start of a muting
sequence.
•
Both beams must be interrupted within a preset time frame 8 ms < t < tmax. The
setting of the timing tmax also sets the muting maximum duration ∆max : select the tmax
timing corresponding to the shortest muting duration ∆max enabling the object transfer
(refer to chapter 2.4.2 SM inputs).
Failure to comply with these instructions could result in death or serious
injury.
ADDITIONAL PROTECTIONS
Additional hard guardings must be designed and installed in such a way that people
cannot enter the dangerous area without being detected by the protective
equipment. Particularly, a person following parts vehiculed towards the dangerous
zone must be detected when interrupting the safety light curtain detection field.
Failure to comply with these instructions could result in death or serious
injury.
