8.23.6 Initializing the Safety Logic Circuit File
If the following alarm shown below appears when starting the controller, it
will become the management mode. The alarm occurs when the file does
not match the file written in the FLASH ROM of the machine safety circuit
board (type: YSF21-E). For example, if the machine safety circuit board is
replaced the spared part, the alarm will occur.
When the alarm occurs, perform the following procedures to restore.
When loading the safety logic circuit file, the file is not
transferred to the machine safety circuit board (type:
YSF21-E). Thus, perform {WRITE} in the one of the
following windows, such as {M-SAFETY SIGNAL ALLOC},
{TIMER DELAY SET}, {SAFETY LOGIC CIRCUIT} or
{SAFETY SIG. BOARD ALLOC}. The all display information
above are updated, and the file written in the FLASH ROM
of the machine safety circuit board is also updated.
