• 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 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.
