Safety Precautions
Confirm that the calculated reaction times meet the required specifications for all safety
chains.
Serious injury may possibly occur due to loss of required safety functions.
All safety devices and components that are connected to an NX-series Safety Control
Unit must be selected and used to meet the required level of safety and the relevant
safety category.
Serious injury may possibly occur due to loss of required safety functions.
Do not use indicators on the NX-series Safety Control Units for safety operations.
Serious injury may possibly occur due to loss of required safety functions.
Check during the import of the program that the CRC of the program is correct.
Serious injury may possibly occur due to loss of required safety functions.
Check during the import of the user defined function that the CRC of the imported func-
tion block is correct.
Serious injury may possibly occur due to loss of required safety functions.
Do not use non-safety signals, including tag data links, explicit messages, and ex-

Debugging
Before you perform safety validation of the safety programs, complete debugging of
the safety programs.
Otherwise, the Safety CPU Unit will start with safety programs that are not fully debug-
ged and may cause serious personal injury.
Make sure that the area around the system is safe before you change the operating
mode, change present values, or execute forced refreshing. The outputs may operate
and may cause serious injury.
Make sure that the area around the system is safe before you start the system opera-
tion while the online functional test is in progress. The outputs may operate and may
cause serious injury.
Testing Operation
Before you start the system, perform user testing to make sure that all safety devices
operate correctly. The safety signature is validated upon completion of the user testing.
Serious injury may possibly occur due to loss of required safety functions.
