Muting Override Function
Muting override function is used to temporarily stop all
safety functions of the entire protection zone when the
OSSD turns OFF during muting. The override function
is effective when the override input and reset input is
switched in the order as shown below. When the SE1L
is in a override status, the 7-segment display shows the
override code.
Override start condition
Either one of the muting input is ON.
When an object exists in the protection zone.
When the time interval of the override input and reset
input is between 0.03 and 1 second (T3)
Override stop condition
Both of the muting inputs are OFF.
Either the override input or reset input is OFF.
When the override state exceeds the maximum
override time T4.
When an error is detected by the self-diagnosis
function of the SE1L.
When the muting area switched to a different area
during muting.

Before using the muting function, make sure to
perform a risk assessment.

If the above procedures are not followed, critical
injury or death may result.
Reference Monitor Function
The reference monitor function is a function to monitor
the displacement of the SE1L or the structure in the
background used as a reference.
Existence Detection Application Examples
When the reference area is set to a moving part such as
a door, the OSSD will turn OFF if the position of the door
changes.

Access Detection Application Example
The user must configure the reference area for monitoring.
To detect the displacement, set a reference area on each
side. The OSSD will turn OFF when the distance between
the reference background has changed or when an access
is detected. This function must be used when the SE1L is
installed vertically.

Make sure that 2 or

displacement is
detected correctly.
