WARNING
UNINTENDED EQUIPMENT OPERATION
The application of this product requires expertise in
the design and programming of control systems . Only
persons with such expertise should be allowed to
program and apply this product .
Follow all local and national safety codes and standards .
Failure to follow instructions available in user manual
can result in death, serious injury, or equipment
damage .
Device Settings
1. Set the C445 motor management relay to the rated cur-
rent of the motor (according to the name plate or the type
approval certificate of the motor).
2. Set the Trip Class of the C445 motor management relay via
the communication network.
3. Disable auto-reset.
CAUTION
EtherNet/IP and ModBus TCP module with 2-port switch
Configuration
•
Configure a Master IP on the Ethernet network.
•
Do not use an IP address other than Master IP to send net-
work start and stop commands to the C445 communication
card.
•
Design your Ethernet network to block unauthorized network
start and stop commands sent to the C445 motor manage-
ment relay.
WARNING
LOSS OF CONTROL
The designer of any control scheme must consider the
potential failure modes of control paths and, for certain
critical functions, provide a means to achieve a safe
state during and after a path failure .
Examples of critical control functions are emergency
stop and overtravel stop .
• Separate or redundant control paths must be
provided for critical control functions .
• System control paths may include communication
links . Consideration must be given to the implications
of anticipated transmission delays or failures of the link .
• Each C445 module must be individually and
thoroughly tested for proper operation before being
placed into service .
Failure to follow these instructions can result in death,
serious injury, or equipment damage .
WARNING
UNEXPECTED RESTART OF THE MOTOR
Check that the PLC application software:
• considers the change from local to remote control,
• manages appropriately the motor control commands
during those changes .
When using automated features, assess the safety
risk based on the application . When switching to
the Network control channels, depending on the
communication protocol configuration, the C445 system
can take into account the latest known state of the
motor control commands issued from the PLC and
automatically restart the motor .
Failure to follow these instructions can result in death,
serious injury, or equipment damage .
