General

Please note:
Muting means a temporary suspension of the safety function. For this reason, the muting
function must have a time restriction. When the muting sensors are activated and the mut-
ing state begins, an internal clock is started. If the muting sensors are still active after 10
minutes (status when delivered), the muting state is cancelled and the safety laser scanner
switches to a safe condition.
The time monitoring of the muting function can be set in PSENscan Configurator.

WARNING!
Loss of safety function due to a safety distance that is too low
Depending on the application, serious injury or death may result.
}
Depending on the degree of dust filtering, it is necessary to consider an
allowance for calculating the safety distance when installing the safety
laser scanner near intense light sources or reflective surfaces into ac-
count (see Distance to intense light sources and to reflective
surfaces [ 37]).
– When calculating the safety distance, ensure that the allowance is
considered depending on the dust filtering.
– Ensure that the new safety distance fulfils the specifications of the
safety assessment.
CAUTION!
Risk of injury due to insufficient safeguard.
Accessing the danger zone can lead to injuries.
– Use an appropriate safeguard to prevent access to the danger zone.
CAUTION!
Risk of injury due to loss of the safety function.
If time monitoring for the muting function is set to ∞, the muting function is
not cancelled until the muting sensors are no longer active.
This setting does not comply with the specifications of EN ISO 61496-1.
– Avoid a situation in which sustained muting is not detected.
