Note!
The optional integrated solenoid valve is
implemented by a forced venting function in
Types 3731-x Positioners.
1.2
Diagnostic tests
There are two main groups of diagnostic
tests available.
Statistical information AUTO
These tests are performed while the process
is running (automatic mode) without disrupt-
ing the process.
Activated tests are automatically performed
when they are triggered by their start condi-
tion (e.g. data logger and drive signal dia-
gram hysteresis).
Other tests are already performed in the
background without being activated (e.g.
histograms, cycle counter, drive signal
steady-state and end position trending).
Tests MAN
These tests should not be performed while
the process is running (i.e. in manual mode
instead) as the positioner cannot follow the
reference variable at the same time.
The valve is moved to a certain position de-
fined by the test settings and the valve may
move through its full range.

Activating EXPERT
+
The extended EXPERT
+
diagnostics can be
activated later at the positioner when
EXPERT
+
is not already activated on delivery
of the positioner.
The required activation code can be ordered
(order number 1400-9318). On ordering
this option, specify the serial number of the
positioner (see nameplate or in the soft-
ware).
