Siemens SIMATIC NET SCALANCE XR-300 User Manual

• Note the wiring rules (Page59).
• The signaling contact can be controlled manually via the user interfaces. Information on this
can be found in the Con󹪝guration manuals (Page8).
WARNING
Risk of electric shock and property damage due to voltage being too high
The signaling contact can be operated in the voltage range of 19.2 to 31.2 V DC or 19.2 to 30.0
V AC and subjected to a maximum load of 100mA.
With higher voltages or currents, there is a risk of electric shock and damage to the device.
Position and assignment
The connection is located on the front of the device.

Signaling faults
• The signaling of errors by the signaling contact is synchronized with the fault LED "F", see
section ""F" LED (Page37)".
All errors that the fault LED "F" indicates (freely con󹪝gurable) are also signaled by the
signaling contact.
• If an internal fault occurs, the fault LED "F" lights up and the signaling contact opens.
• If you connect a communications node to an unmonitored port or disconnect it, this does not
cause an error message.
• The signaling contact remains open until one of the following events occurs:
– The problem is eliminated.
– The current status is entered in the fault mask as the new desired status.
