CHAPTER10 LOADING AND INSTALLATION
In order to increase the reliability of the system and exploit the maximum performance of
its functions, this section describes the methods and precautions for the mounting and
installation of the system.
DANGER
When a safety PLC detects an error in an external power supply or a fail-
ure in PLC main module, it turns off all the outputs.
Create an external circuit to securely stop the power of hazard by turning
off the outputs.Incorrect configuration may result in an accident.
Create short current protection for a safety relay, and a protection circuit
such as a fuse, and breaker, outside a safety PLC.
When data/program change, or status control is performed from a PC to
a running safety PLC, create an interlock circuit outside the sequence
program and safety PLC to ensure that the whole system always oper-
ates safely.
For the operations to a safety PLC, pay full attention to safety by reading
the relevant manuals carefully, and establishing the operating procedure.
Furthermore, for the online operations performed from a PC to a safety
CPU module, the corrective actions of the whole system should be pre-
determined in case that a communication error occurs due to a cable
connection fault, etc.
All output signals from a safety CPU module to the CC-Link Safety sys-
tem master module are prohibited to use.
These signals can be found in the CC-Link Safety System Master Mod-
ule User's Manual.
Do not turn ON or OFF these signals by sequence program, since turn-
ing ON/OFF these output signals of the PLC system may cause malfunc-
tions and safety operation cannot be guaranteed.
When a safety remote I/O module has detected a CC-Link Safety error, it
turns off all the outputs.
Note that the outputs in a sequence program are not automatically
turned off.
If a CC-Link Safety error has been detected, create a sequence program
that turns off the outputs in the program.
If the CC-Link Safety is restored with the outputs on, it may suddenly
operate and result in an accident.
To inhibit restart without manual operation after safety functions was
performed and outputs were turned OFF, create an interlock program
which uses a reset button for restart.
