• The vehicle should be designed to make it impossible for
people to ride on it.
• Limit the size of the entry area by applying appropriate safety
measures. People must not be permitted to enter the danger
area during the muting phase.
• Make sure that you select the correct muting configuration
(DIP switch position 2). The "OFF" position is provided
exclusively for safety light curtains with an L-shape
configuration. Any discrepancy in the configuration may
cause the muting function to operate incorrectly and reduce
the level of safety.
• In each case, the muting sensors must be positioned so that
muting cannot be activated by somebody passing through the
protected field.
• Muting can be activated in 2 ways:
- Activation of both muting inputs simultaneously (not in the case
of L-shaped muting)
- Activation of muting input 1 and then muting input 2, or vice-
versa.
• Muting cannot be activated if the protected field is interrupted
(“SAFE” LED lights up red).
• An "infinite" muting timeout does not conform to the
specifications of EN 61496-1. If the muting timeout has been
set to "infinity", the muting sensors must be tested at
intervals that are compatible with the process. This can be
done by shutting down the plant or by idling the muting
channel, for example.
• If the muting timeout is set to “infinity”, the level of safety that
can be achieved may be reduced.
