Safety Precautions - Mitsubishi Electric NZ2GF2BN-60DA4 User Manual

Before using this product, please read this manual and the relevant manuals carefully and pay full attention
to safety to handle the product correctly.
The precautions given in this manual are concerned with this product only. For the safety precautions of the
programmable controller system, refer to the user's manual for the CPU module used.
In this manual, the safety precautions are classified into two levels: "
WARNING
CAUTION
Under some circumstances, failure to observe the precautions given under "
serious consequences.
Observe the precautions of both levels because they are important for personal and system safety.
Make sure that the end users read this manual and then keep the manual in a safe place for future
reference.
[Design Precautions]
● When a communication failure occurs in the network, data in the master module are held. Check Data
link status (each station) (SW00B0 to SW00B7) and configure an interlock circuit in the program to
ensure that the entire system will operate safely.
● Do not use any "use prohibited" signals as a remote I/O signal. Do not write any data to the "use
prohibited" areas in the remote register. If these operations are performed, correct operation of the
module cannot be guaranteed.
● Configure safety circuits external to the programmable controller to ensure that the entire system
operates safely even when a fault occurs in the external power supply or the programmable controller.
Failure to do so may result in an accident due to an incorrect output or malfunction.
(1) The status of analog output depends on the setting of various functions that control the analog
output. Exercise great caution when setting those functions. For details of the status of analog
output, refer to Page 92, Section 8.7.
(2) Due to failure of the output element or internal circuit, normal output may not be obtained
correctly. Configure an external circuit for monitoring output signals that could cause a serious
accident.
