WARNING
System Restart After Fault Acknowledgment/Restart
Can Cause Death, Serious Injury, or Damage to Property.
After fault acknowledgment/restart, the system immediately resumes operation with the
values speci󹪝ed by the control, and outputs are activated if the power-on condition is ful󹪝lled.
Take appropriate measures (e.g. start button with monitored starting) to prevent unintentional
restarting and to ensure a de󹪝ned start of the system.
