The behavior of the current output in the event of faults is defined in the following
parameters:
• Alarm current FCU "MIN": Lower alarm current (≤3.6 mA) (optional, see the following
table)→  62
• Alarm current FCU "MAX" (factory setting): Upper alarm current (≥21 mA)→  62
• Alarm current FCU "HLD" (HOLD) (optional, see the following table): Last measured
current value is held. When the device starts, the current output is set to "Lower alarm
current" (≤3.6 mA). →  62
• The selected alarm current is used for all errors.
• Errors and warning messages are displayed via IO-Link.
• Errors and warning messages are displayed only on the primary value page
(topmost display level) and are not displayed in the operating menu.
• In the operating menu the error is only indicated by the color of the display
background.
• The status LED always indicates an error.
• It is not possible to acknowledge errors and warnings. The relevant message
disappears if the event is no longer pending.
• The failsafe mode can be changed directly when a device is running (see the
following table).
Changing the failsafe mode After confirming with 
from MAX to MIN active immediately
from MIN to MAX active immediately
from HLD (HOLD) to MAX active immediately
from HLD (HOLD) to MIN active immediately
from MIN to HLD (HOLD) active outside the fault state
from MAX to HLD (HOLD) active outside the fault state
10.5 Behavior of the device in the event of a voltage drop
A diagnostic message is not output. The configuration and the settings made are retained.
10.6 Behavior of the device in the event of an incorrect
entry
In the case of incorrect entries, the value entered is not accepted. No fault or warning is
issued in this case. The value to be adjusted cannot be changed to a value outside the
specified limit. This makes it impossible to configure the device using incorrect values. An
exception to this is the configuration of the span that results in a violation of the turn
down, which in turn gives rise to a fault state.
10.7 Resetting to factory settings (reset)
See Reset to factory settings (RES) parameter description→  71.
11 Maintenance
No special maintenance work is required.
Keep the pressure compensation element (1) free from contamination.
