What can be done by the setting tool

Setting Adjusted to Application

Fixed Blanking Function

Overview
Disables F3SJ's specified beams.
Install protective structure for all zones of disabled zone so that a worker should not be able to
approach hazardous zone of a machine without passing through zones disabled by the fixed blanking
function.
Otherwise it may result in serious injury.
If allowable beams are designated for fixed blanking, detection capability gets larger near an object
that interrupts beams. Calculate a safety distance based on the setting.
You must ensure that a test rod should be detected in all zones where it should be detected after
setting the fixed blanking function. Failure to do so may result in serious injury.
Example
•A belt conveyor must be ignored which always sits in a detection zone.
Functional Description
• Fixed Blanking Function
A function that disables a part of F3SJ's detection zone. Safety output will be kept ON status even if an
object exists in the disabled zone.
For beams with fixed blanking designation, one zone is set for beams in concatenation, and up to 5
zones can be set as fixed blanking zones.
• Fixed Blanking Zone Setting
An zone for fixed blanking zone must be configured. It is possible to perform teaching and set the
designated beams manually with the interrupting object placed in the appropriate position. In this
example shown below, the 5th and 10th beams are set as bottom and top beams respectively.
- Upper Beams: Indicate beams on F3SJ's terminal.
Lower Beams: Indicate beams on F3SJ's power supply end.
- Only one zone can be configured as a fixed blanking zone by the setting console.
- Up to 5 zones can be configured as fixed blanking zones by the PC tool for F3SJ.
- To reconfigure F3SJ, for which multiple zones have been already configured by the PC tool for F3SJ, setting
recovery (to factory shipment setting) must be executed before the reconfiguration.
To configure multiple zones, use the PC tool for F3SJ.
