Ceraphant PTP31B, PTP33B Diagnostics and troubleshooting
Endress+Hauser 43
The behavior of the current output in case of fault is defined by the following parameters:
• FCU "MIN": Lower alarm current (≤3.6 mA) (optional, see the following table)→  58
• FCU "MAX" (factory setting): Upper alarm current (≥21 mA) →  58
• FCU "HLD" (HOLD): Last measured current value is held. When the device starts, the
current output is set to "Lower alarm current" (≤3.6 mA). →  58
• The selected alarm current is used for all errors.
• 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).

9.5 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.
9.6 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, which results in a violation of the turn
down, which in turn gives rise to a fault state.
9.7 Disposal
When disposing, separate and recycle the device components based on the materials.
