1Intendeduse
The bus node CPX-FB37 is intended exclusively for use in CPX terminals, as a parti-
cipant in the EtherCAT network and as follows:
– in excellent tec hnical condition
– in original status, without unauthorised modifications
– within the limits of the product defined through the technical data
– in an industrial environment.
You can find detailed information in the bus node description
(P.BE-CPX-FB37-...) and in the CPX system description (P.B E-CPX-SYS-...).
You can receive information on EtherCAT in the Internet:

3.2 LED displays
Behaviour of the LED indicators in normal operating status:
– The LEDs “Run”, “PS” and “PL” are illuminated.
– The LEDs “LA/X1” and “LA/X2” are illuminated or flash if the assigned network
connection is use d.
– The L EDs “Error” and “SF” are not illuminated.
– The L ED “M” is illuminated with the setting “System start with saved
parameters”.
– The LED “M” flashes if “Force” is active.

Warning
Danger of injury to people, damage to the machine and system resulting from
uncontrolled movements of the actuators and undefined switching states
• Switch off the operation and load voltage supplies.
• Switch off the compressed air supply.
• Exhaust the valve terminal pneumatics.
Warning
Danger of electric shock
• For the electrical po wer supply, use only PELV circuits in accordance with
IEC/E N 60204-1 (Protective Extra-Low Voltage, PELV).
• Observe the general requirements of IEC/EN 60204-1 for PELV circuits.
• Only use voltage sources that ensure a reliable electric separation of operat-
ing voltage in ac c ordance with IEC/EN 60204-1.
Note
Damage to the electronics
The bus node includes electrostatically sensitive devices.
• Donottouchanycomponents.
• Observe the handling specifications for electrostatically sensitive devices.
Note
• Only commission a CPX terminal which has been completely mounted and
connected.
• Observe the specifications in the CPX system desc r iptio n, in t he descriptions
of the valve terminal used as well as in the assembly instructions of the indi-
vidual co m ponents.
