IMPROPER INSTALLATION
•
The distance between sensors SM1 & SM2 shall not allow a person to actuate
both sensors within the preset time frame.
•
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 shall be detected when interrupting the safety light curtain
detection field.
Failure to comply with these instructions could result in death or
serious injury.
•
Sensors SMs and EMs must be installed respectively before and after the
protective equipment detection field. Their relative position shall be calculated taking
into account the selected maximum muting duration ∆max (see chapter 2.4.2 SM
inputs).
•
The distances between sensors SM1 & SM2 and the safety light curtain shall be
calculated taking into account the size of the object which must be detected : the
object must interrupt the safety light curtain detection beams, before releasing
either sensors SMs. The distance between the first sensor SM1 and the protective
field must be smaller than the size of the vehiculed object, otherwise the muting
sequence stops as soon as the first sensor SM1 is released and the intrusion of the
object inside the protective field leads to the immediate stoppage of the machine.
