- Excessively long switching times of the involved relays in the chain between the control-is-ready output signal (MC.RDY, STO.A.G) and the control-is-ready acknowledgment (I3, ES.A, ES.B) during the EMERGENCY STOP or switch-on routine
- Control-is-ready acknowledgement (I3, ES.A, ES.B) has a short circuit to +24 V

Error correction

Check the emergency-stop circuit:
- Check / replace the applicable relays in the electrical cabinet
- Check / restore the contacts / wiring
- Inform your service agency
