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.

Signaling faults
• The signaling of errors by the signaling contact is synchronized with the fault LED "F", see
section ""F" LED (Page 33)".
All errors that the fault LED "F" indicates (freely configurable) 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.
