Meaning Explanation
• This relay turns on if an error is
detected by diagnostics. (Also turns on
if an error is detected by an
annunciator or the CHK instruction.)
• This relay remains on even after the
system returns to normal.
• This relay turns on if an error is
detected by diagnostics. (Also turns on
if an error is detected by an
annunciator.)
• This relay remains on even after the
system returns to normal.
• This relay turns on if an error is
detected by self-diagnostics. (Remains
off if an error is detected by an
annunciator or the CHK instruction.)
• This relay remains on even after the
system returns to normal.
• This relay turns on if an error is
detected by self-diagnostics. (Remains
off if an error is detected by an
annunciator.)
• This relay remains on even after the
system returns to normal.
This relay turns on if error common

information
Conducts error reset operation
• This relay turns on if the battery voltage
of the CPU module or the memory card
drops below the rated value.
• This relay remains on even after the
battery voltage returns to normal.
• The on/off timing is synchronized with
that of the BAT. LED.
• This relay turns on if the battery voltage
of the CPU module drops below the
rated value.
• This relay remains on even after the
battery voltage returns to normal.
• The on/off timing is synchronized with
that of the BAT. LED.
• This relay turns on if the battery voltage
of the CPU module drops below the
rated value.
• This relay remains on even after the
battery voltage returns to normal.
• The on/off timing is synchronized with
that of the ERR. LED.
This relay has the same specifications as
those of SM51 except that this relay turns
off after the battery voltage returns to
normal.
