When you have properly connected the muting application and the NSR-0801, select the following parameter
settings according to your intended application in the menu option Muting Function of your PC software.
First please select the operating mode and the transport direction with the mouse pointer (arrangement and
number of muting sensors).
- Muting with 2 sensors, diagonal arrangement
Muting mit 2 diagonally mounted muting sensors
Transport direction: Material transport in two directions (default)
Selectable options: Conveyor stop, muting cycle shortened, override, protective field range
- Muting with 2 sensors, parallel arrangement
Muting with 2 muting sensors;
Attention!
Do not mount the muting sensors outside of
the danger zone!
Transport direction: out of the danger zone, muting cycle shortened (default).
Selectable options: Conveyor stop, override, protective field range
- Muting with 4 sensors, parallel arrangement
Muting with 2 muting sensors each, symmetrical arrangement in front of and after the
protective field of the SLG 420.
Transport direction: Material transport selectable in both directions
Selectable options: Conveyor stop, muting cycle shortened, override, protective field range
5.9.1 Muting cycle duration
The muting cycle duration is the time between activation and termination of the material tansport into or out of the
danger zone.
The muting cycle duration depends on the length of the material, the conveyor speed and the arrangement
of the sensors. The duration setting must comprise one complete muting cycle (release of all sensors). A new
muting cycle can only be started when all sensors are released (no dimming).
The muting cycle duration can be set between a few second and many hours. Longer muting cycle durations
can be generate a dangerous operating situation.
Consider variations of conveyor speed, position and length of the material when setting the muting
cycle duration.
5.9.2 Simultaneouness of the sensors
The time range between the 1st and the 2nd muting sensor is monitored. Thus a symmetrically shaped body
can be differentiated clearly from other time ranges (intrusion of a person) by an appropriate arrangement
of the muting sensors.
The simultaneouness setting should take variations of the conveyor speed, position and length of the
material into consideration.
Simultaneouness of the sensors can be set between 1 and 3 seconds.
