EDM
INSTRUCTION MANUAL 45
Figure 8 - EDM connection with manual restart selected on SG4-N models
The function controls the 24VDC normally-closed contact switching according to the
changes of the OSSDs status.
Figure 9 - EDM timings
The EDM status is antivalent with OSSDs: the timing diagram explains the relationship
between the cause (OSSDs) and the effect (EDM) with the maximum permissible delay.
Tc <= 350 msec (time between OSSD OFF-ON transition and EDM test)
To >= 100 msec (time between OSSD ON-OFF transition and EDM test)
(two different times for the mechanical contact driven by a spring)
