Hazard Classifications

Safety Precautions

!CAUTION

•Read the Safety Precautions described in your PLC's User's Manual before using the PLC.

•Carefully design a fail-safe system in order to avoid an unsafe situation caused by PLC failure. When the PLC detects an error in its self-diagnostics, the PLC goes into the error mode. In the error mode, all the PLC outputs turn OFF and the analog outputs go to 0 (zero).
