[. . . ] Lights up while a HIGH state signal is input to T41. Blinks when an error relating to logical AND connection input occurs. Lights up while a HIGH state signal is input to T51. Blinks when an error relating to logical AND connection input occurs. Lights up while the Instantaneous safety outputs (S14, S24, S34) are in the ONstate. Blinks when an error relating to the instantaneous safety output occurs. Lights up while OFF-delayed safety outputs (S44, S54) are in the ON-state. Blinks when an error relating to OFF-delayed safety output occurs. Lights up or blinks when an error occurs.
