3.7.1 Self-diagnostic function of OSSD
Self-diagnostic is a function to detect the malfunction in the output circuit by switching OFF the OSSD 1
to OSSD 4 for an interval of 300 μ s. Therefore, safety-relay or power converter used must not response to
this diagnostic function. Figure 3-14 below shows the timing chart of the self diagnostic function of the
OSSD during dual protection mode.

In single protection mode, self-diagnostic function is done for OSSD 1 and OSSD 2 only.
3.7.2 Lockout state
When an error is detected by the self-diagnostic function and SE2L cannot operate normally it will
switch to lockout state. During the lockout state, OSSD1/2, OSSD3/4, WARNING1, WARNING2 will
switch to OFF-state. After removing the error, SE2L can be reset by restoring the power to release from the
lockout state.
3.7.3 Interlock function
Interlock is a function to prevent automatic restart of the OSSD signal switching from OFF-state to
ON-state. Automatic restart, manual restart and manual start interlock functions are configurable using the
SLS Project Designer.
