Using safety controllers

Observe the ZVEI specifications for safety sensors if you use a safety PLC.

The starting and stopping pulses of the safe digital outputs (F-DO) used must be ≤ 1 ms. The ratio must not fall below 1:1000.

INFORMATION

If the DC 24 V supply at X17 is switched off safely (STO activated), you must observe chapter "Requirements on the external safety controller" with regard to the test pulses.
