2 I/O modules EU5E-SWD…
2.9 Digital module EU5E-SWD-4D4D-R
SmartWire-DT module IP20 01/20 MN05006001Z-EN www.eaton.com 37
Precondition:
• There must be 24 VDC at Upow on the gateway
• If EU5C-SWD-PF..-1 power feeder modules are installed upstream of the
I/O module but downstream of the gateway, they must also be powered
via the Upow terminal.
• There must be 24 VDC at the 0 V, 24 V terminals on the I/O module in
order to power the outputs
• The output channels must be configured appropriately
Condition for disconnection:
• The 24 VDC at the I/O module (power for outputs) being removed -> No
energy for driving the downstream contactors. However, the outputs
remain logically "switched" and would remain on when the power is
restored.
• The Upow 24 V at the coordinator (gateway) or EU5C-SWD-PF2-1 module
being switched off. This would cause the module to lose its operating
voltage (15 V) and no longer be able to drive the outputs. After switching
the power back on, the outputs would remain off.
• The configuration button on the gateway being pressed or the corre-
sponding function being run in SWD-Assist, triggering a new configura-
tion import as a result. In this case, SmartWire-DT would restart and the
switched outputs would be switched off for a brief moment (a few 100
ms).
• Loading a new PLC configuration with modified parameters.

DANGER
As a result of unintended actuation!
When a project is transferred to a controller, it will have an
immediate effect on the controller's ongoing operation.
This may result in errors in the process being controlled. The
safety mechanisms being used on site must not be disabled as
a result of a project being transferred.
