Description
The device displays warnings and faults. This is done via IO-Link using the diagnostic
message stored in the device. The purpose of all device diagnostics is solely to provide
information to the user; they do not have a safety function. The errors diagnosed by the
device are displayed via IO-Link in accordance with NE107. In accordance with the
diagnostic message, the device behaves as per a warning or fault condition:
Warning (S971, S140, C485, C431, C432):
With this type of error, the device continues to measure. The output signal does not adopt
its fault state (value in the event of an error). The main measured value and the state in
the form of the letter plus a defined number are displayed alternately (0.5 Hz) via IO-Link.
The switch outputs remain in the state defined by the switch points.
Fault (F437, S803, F270, S510, C469, F804):
With this type of error, the device does not continue to measure. The output signal adopts
its fault state (value in the event of an error). The fault state is displayed via IO-Link in the
form of the letter plus a defined number. The switch output changes to the defined state
(open). For the analog output option, an error is also signaled and transmitted via the 4 to
20mA signal. In NE43, NAMUR defines a current ≤3.6 mA and ≥21 mA as a device failure.
A corresponding diagnostic message is displayed. Current levels available for selection:
The selected alarm current is used for all errors. Diagnostic messages are displayed with
numbers and letter via IO-Link. It is not possible to acknowledge all the diagnostic
messages. The relevant message disappears if the event is no longer pending.
The messages are displayed in order of priority:
• Highest priority = first message displayed
• Lowest priority = last message displayed
Options
• Min: Lower alarm current (≤3.6 mA)
• Max: Upper alarm current (≥21 mA)
