Limited short-circuit detection in the input circuits

ATTENTION
• One SP-COPx module has four test signal generators T1 – T4.
• Short-circuits between test signal generators of a SP-COPx module are detected. Short
circuit detection is only ensured between different modules if the test gaps of the test
signal generators are < 4 ms, the test periods
≥
200 ms. Short-circuits past 24 V DC (after
High) at inputs that are connected to test outputs are detected independently of the
length of the test gaps.
Make note of this during wiring (e.g. through separate routing or protected lines)!
