E3NW-ECT EtherCAT Digital Sensor Communication Unit Operation Manual (E429)
Do not attempt to take any Unit apart and do not touch the interior of any Unit while
the power is being supplied. Also, do not turn ON the power supply while the cover
is open.
Doing any of these may result in electric shock.
Do not attempt to disassemble, repair, or modify any Units.
Doing any of these may result in electric shock.
Do not input voltages or currents exceeding the rated range to the Unit.
Using voltages or currents exceeding the rated range may cause Unit failure or fire.
Provide safety measures in external circuits (i.e., not in the Units), including the
following items, to ensure safety in the system if an abnormality occurs due to
malfunction of the PLC or another external factor affecting the PLC operation.
("PLC" includes CPU Units, other Units mounted in the PLC, and Remote I/O
Terminals.)
Not doing so may result in serious accidents.
Emergency stop circuits, interlock circuits, limit circuits, and similar safety measures
must be provided in external control circuits, not in the Units.
The PLC will turn OFF all outputs when its self-diagnosis function detects any error
or when a severe failure alarm (FALS) instruction is executed. As a countermeasure
for such problems, external safety measures must be provided to ensure safety in
the system.
The Slave Unit outputs may remain ON or OFF due to deposits on or burning of the
output relays, or destruction of the output transistors. As a countermeasure for such
problems, external safety measures must be provided to ensure safety in the
system.
When the 24-VDC output (service power supply to the PLC) is overloaded or
short-circuited, the voltage may drop and result in the outputs being turned OFF. As
a countermeasure for such problems, external safety measures must be provided to
ensure safety in the system.
Implement proper measures as part of your communications system or in your
program to ensure safety in the system even when a communications error or
malfunction occurs during remote I/O communication.
