Samson 3730 - Faults

Note! The time required for the initialization
procedure depends on the actuator transit
time and can take a few minutes.
Initialization successfully
completed, positioner runs
in control operation
After a successful initialization, the
positioner runs in control operation indi
-
cated by the control symbol and control
position in % predetermined by the refer
-
ence variable on the display.
A malfunctioning leads to the process being
interrupted. The fault symbol appears on
the display. See section 5.6 for details.
Canceling initialization
The initialization can be canceled by press-
ing . The positioner then moves to the
fail-safe position (indicated by
S on the dis-
play).
A new initialization can be started directly
afterwards.
5.6 Faults
On the occurrence of a fault, the fault sym
-
bol appears at the bottom of the display.
By turning the button past Code
P0 or
P16 , the respective error code E0 to E15 to
-
gether with
ERR appear on the display.
Refer to the code list in section 6 for the
cause of the errors and how to remedy
them.
Example:
If, for instance, a travel has been entered
over Code
P4 (nominal range) which is
larger than the maximum valve travel possi
-
ble, the initialization process would be inter-
rupted (error code
E2 ) because the rated
travel would not have been reached (error
code
E6 ). The valve moves to the fail-safe
position (
S indicated on the display).
Display of the fault
indication
The nominal range (Code P4 ) must be
changed and the positioner re-initialized to
remedy this problem.
