6.3 T-Activation Mode
The T-muting activation mode is the default and standard application for muting. Four muting sensors are
used in two pairs (OR function), connected to the two Muting inputs, Muting A and Muting B. This muting
activation mode allows bi-directional transport of material.
NB!
– d1 is the distance between the muting sensors. It must be more than 250 mm and needs to be checked
additionally in regards to the speed of the material transport and time limitation in the muting function.
– d2 is the distance between the Muting sensor B and the Focus II system. It must be as short as possib-
le. Timing limitations and the speed of the material transport must be considered additionally.
– d3 is the distance between the two sensors connected to Muting A input. This distance represents the
minimum length of the material to be detected.
Timing requirements and limitations:
• If Muting A is activated, Muting B must be activated within 120 s to activate the muting function. Other-
wise muting function is not achived.
• Muting A and Muting B cannot be activated at the same time. A minimum time difference is approxi-
mately 30 ms and is mandatory.
• Maximum muting time is 600 s. After this time, muting function is stopped even if the Muting inputs are
still active.
• The Focus II allows that Muting A or Muting B drop for a maximum time of 200 ms without stopping the
muting function. A time longer than 200 ms is detected as a muting stop.
