NOTICE
When using the DSU/DSD instruction, the timer (TMR) must be set to the output signal. If
{WRITE} is press without setting the timer (TMR) to the output signal, the error message
“ERROR 4241: Safety logic circuit is not set correctly” is shown on the message area of the

the ON/OFF status of the input signal.
