WARNING
Serious injury may possibly occur due to loss of required safety functions. Do
not use the NE1A-series Controller's test outputs as safety outputs.
Serious injury may possibly occur due to loss of required safety functions. Do
not use DeviceNet standard I/O data or explicit message data as safety data.
Serious injury may possibly occur due to loss of required safety functions. Do
not use indicators or 7-segment display on the NE1A-series Controller for safety
op-erations.
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 and
test outputs.
Serious injury may possibly occur due to loss of required safety functions. Wire
the NE1A-series Controller properly so that the 24-VDC line does NOT touch the
out-puts accidentally or unintentionally.
Serious injury may possibly occur due to loss of required safety functions.
Ground the 0-V line of the power supply for external output devices so that the
devices do NOT turn ON when the safety output line or the test output line is
grounded.
Serious injury may possibly occur due to loss of required safety functions.
Clear previous configuration data before connecting the devices to the network.
Serious injury may possibly occur due to loss of required safety functions. Set
suitable node addresses and a suitable baud rate before connecting the devices
to the network.
Serious injury may possibly occur due to loss of required safety functions. Per-
form user testing and confirm that all of the device configuration data and oper-
ation is correct before starting system operation.
Serious injury may possibly occur due to loss of required safety functions.
When replacing a device, configure the replacement device suitably and confirm
that it operate correctly.
Serious injury may possibly occur due to loss of required safety functions. Use
appropriate components or devices according to the requirements given in the
following table.
Control device
Requirements
Emergency stop switch
Use approved devices with a direct opening mechanism compliant with IEC/
EN 60947-5-1.
Door interlocking switch or
limit switch
Use approved devices with a direct opening mechanism compliant with IEC/
EN 60947-5-1 and capable of switching micro-loads of 4 mA at 24 VDC.
Safety sensor
Use approved devices compliant with the relevant product standards, regula-
tions, and rules in the country where they are used.
Relay with forcibly guided
contacts
Use approved devices with forcibly guided contacts compliant with EN
50205. For feedback signals, use devices with contacts capable of switching
micro-loads of 4 mA at 24 VDC.
