External Device Monitoring (EDM) Function
EDM function monitors the input signal status of a machine
or AGV. The SLS Configurator is used to configure the
EDM. When an EDM signal detects an error, the OSSD
signal turns OFF. The EDM input signal is always the
inverse of the OSSD signal. The EDM input signal ON/OFF
delay can be configured. Do not connect the EDM when
the EDM function is not used.

Note: When the EDM function is disabled, do not connect the EDM as an
error will occur.

Muting Function
Muting function is a function to temporarily stop the safety
function in the protection zone. During muting, the OSSD
signal will remain ON even when an object is detected
in the muting area. The muting function can be started
and stopped using two signals that are independently
wired. Muting areas can be configured using the SLS
Configurator. When the muting input satisfies the starting
conditions, the SE1L stops the safety function within 60
ms. (For details, see the user's manual)
Muting Start
Muting function starts when the following conditions are
satisfied:
1) When OSSD is ON and there are no objects within the
protection zone.
2) 2 muting input signals which are independently wired are
switched to the preset input order or switched within the
time interval of T1.
To start muting, see the configuration below. The SLS
Configurator can be used for the configuration below. (For
details, see the user's manual)
Muting input order
Muting 1 Muting 2
Muting 2 Muting 1
Input time difference (T1)
1 second
3 seconds
5 seconds
10 seconds
Muting Stop
Muting function stops when the following conditions are
satisfied:
1) Either one of the muting input turns OFF.
2) When the muting status exceeds the maximum muting
time T2.
3) When an object is detected in a protection zone that is
not covered by a muting area.
4) When an error is detected by a self-diagnosis function.
5) When the muting area is switched to a different area
during muting.
The following shows the necessary configuration to end
the muting function.
