Functions and Features

SL-V-M-NO2-E
2-13 Reduced Resolution
This function is only enabled through the SL-VH1S.
In case of normal operation, the OSSD goes to the OFF state when the SL-V detects interruption in the
detection zone.
When you enable this function and set the number of ignored beams, the OSSD keeps the ON state
when the number of beams blocked by the object is less than or equal to the set number of ignored
beams. The OSSD only changes to the OFF state when the object consecutively interrupts more beams
than the set number of ignored beams.
The reduced resolution can be enabled to any of beam axis, including the beam axis of SL-V in series
connection.
When the reduced resolution function is applied, the detection capability varies depending on
your configuration. The following is the calculating formula.
[Detection capability under the reduced resolution function]=[Original detection
capability]+[Beam axis spacing]*[Number of ignored beams]
Therefore, make sure to accurately calculate the safety distance according to the detection
capability, and install the SL-V at a distance greater than or equal to the minimum safety
distance away from the hazardous zone or hazard. The installation of additional safety
measures, such as a safeguarding, may be required if the detection capability varies due to
the configuration of the reduced resolution function. On your own responsibility, you must
perform the risk assessment based on your configuration of the reduced resolution function in
order to reduce the risk.
Example: The number of ignored beams is set to "1"
The OSSD goes to OFF-state when the consecutive two beam axes are interrupted.
Settable range for the number of ignored beams: one beam axis to the half of all beam axes (round down the
number of decimals)
If the SL-V is connected in series, the all beam axes means sum of the beam axes of SL-V main unit and sub
units.
Procedure for Configuration
Refer to the "SL-VH1S User’s Manual".
