Precautions for Safe Use
If the MC indicator is flashing at 0.25-s intervals, it indicates that the Memory
Cassette is being accessed (read or written).
Do not turn OFF the internal circuit power supply to the G9SP-series Control-
ler or remove the Memory Cassette until the indicator stops flashing. If the
power supply is turned OFF while data is being accessed, data in the G9SP-
series Controller may be corrupted or lost.
This section describes the I/O indicators that are provided on the G9SP-
series Controller.
Self-diagnosis is performed to detect circuit failures and other circuit problems
for Safety Input and Safety Output terminals. If errors are detected in this self-
diagnosis, the terminal where the error occurred will be shown by a red indica-
tor.

Serious injury may possibly occur due to loss of required safety functions. Do
not use indicators on the G9SP-series Controller for safety operations.
