WARNING
Safety functions may be impaired and serious injury may occasionally occur.
Do not use the test outputs of the products as safety outputs.
Safety functions may be impaired and serious injury may occasionally occur.
Do not use DeviceNet standard I/O data or explicit message data as safety sig-
nals.
Safety functions may be impaired and serious injury may occasionally occur.
Do not use the indicators on the products for safety operations.
Serious injury may possibly occur due to breakdown of safety outputs or test
outputs. Do not connect loads beyond the rated value to the safety outputs or
test outputs.
Safety functions may be impaired and serious injury may occasionally occur.
Wire the output lines and 24-VDC line so that they will not touch each other to
prevent a load from turning ON due to a short-circuit with the 24-VDC line.
Safety functions may be impaired and serious injury may occasionally occur.
Ground the 0-V side of the external power supply to prevent an output from turn-
ing ON due to a ground fault in a safety output or test output.
Safety functions may be impaired, and serious injury may occasionally occur.
Before connecting a device to the network, clear the previous configuration
data.
Safety functions may be impaired and serious injury may occasionally occur.
Before connecting a device to the network, configure the appropriate node
address and the baud rate.
Safety functions may be impaired and serious injury may occasionally occur.
Before operating the system, conduct user testing to confirm if the configura-
