Contacts
In the safety circuit diagram, the contact SE..QS closes if the
coil ES..I1 is addressed (logic 1) and the Start command is
received via the Reset coil. The contact SE..QS stays closed
until the coil SE..I1 is energized.
If you wire the contact SE..ER in the standard and/or safety
circuit diagram, it indicates the presence of an error by
closing.
Memory requirement
The function block SE requires 20 bytes of memory.
Operation of the function block
The Start command at coil SE..I1 prepares the function block
for enabling the safe start of an application. Depending on
the operating mode selected, the Start enable is triggered by
the Reset coil SE..RE.
