Figure 3-19 EDM timing chart
In dual protection mode, EDM2 circuit and timing chart for OSSD3 and OSSD4 are same as above.
3.9 Muting function
Muting function temporarily suspends the safety function in the configured zone of SE2L when the
specified conditions are fulfilled. In the muting state OSSD remains in the ON-state even when an object is
detected in the configured muting zone. Two independent hard wired input signals are provided to start and
end the muting function. Muting zone is configured using the SLS Project Designer (Refer to section 7.9.1).
When muting inputs fulfill the muting start conditions, SE2L will suspend the safety function within 60ms
and resume the safety function if they fulfill the muting stop conditions.
3.9.1 Muting start condition
Muting function will start when the following conditions are fulfilled:
a) There are no objects in the protection zone and the OSSD is in ON-state.
b) The two independent hard wired muting input signals are switched to ON state in the predefined
sequence within the pre-set time interval. However, the switching interval between two input signals
should not be 0 (Refer to figure 3-20).
The following configurations are necessary for the muting function. User can configure these by using the
SLS Project Designer.
 Muting inputs sequence
▶
Muting 1  Muting 2
▶
Muting 2  Muting 1
 Time interval between two inputs (T1)
▶
1second
▶
3seconds
▶
5seconds
▶
10seconds
When using muting function in dual protection mode, Muting 3 and Muting 4 are configured in the similar
way.
