5.2.4.5 4-Sensor Linear Muting with Sequence Monitoring
The 4-sensor linear muting with sequence monitoring enables the user to transport an object into or out of the
danger zone. Two MS are located inside and two MS are located outside the danger zone.
The distances a and b represent the distances between the muting object and a separating safeguard
(fence). They must be designed so that no one can enter the danger zone unnoticed while the muting is acti-
vated. The separating safeguard must therefore be installed directly behind the ESPE to prevent bypassing.
NOTE!
• The 4-sensor linear muting with sequence monitoring checks the correct activation
sequence of the MS. MS1 or MS4 must be activated first. MS2 or MS3 must then be acti-
vated depending on which of the sensors was approached.
• The “direction setting” function can be used to restrict the permissible direction of the
object transport to one direction.
• The 4-sensor linear muting with sequence monitoring does not use time monitoring when
activating the individual MS. A time restriction is only possible via the maximum muting
duration MMD.
• If the function “Muting end through clearing of the ESPE” is activated, the muting se-
quence ends as soon as the safety field is free again.
• The “Gap suppression” function can increase the availability of the system by accepting
signal interruptions of less than 250 ms on the MS.
• Due to the lack of time monitoring, this function should only be used if no other muting
type is suitable.
For better understanding, the scenario of material movement into the danger zone is outlined below ( Figure
8 ). If the object is to be transported out of the danger zone, the designation MS1 should be replaced with
MS4, MS2 with MS3, etc.
