Samson 3725 - Canceling Initialization

56 EB 8394 EN
Operating the positioner
The type and extent of self-adaptation depends on the preset parameters. MAX applies as
the default setting for the nominal range (Code P4). During the initialization process, the po-
sitioner determines the total travel range or rotational range of the valve (from the CLOSED
position to the opposite end position).
Alternatively, a different travel can be selected in Code P4 (see code list in section11.2).
The travel set in Code P4 is only limited during initialization. However, it might be exceeded in
closed-loop control when the control signal is higher than 20mA.
Start initialization (enable conguration as described in section7.2).
1. Touch or until Code P15 appears.
2. Press
and hold for six seconds. 6...5...4...3...2...1 is counted
down on the display.
The initialization starts and INIT blinks. The time required for the ini-
tialization procedure depends on the actuator transit time and can
take a few minutes.
%
Initialization successfully completed. The positioner is in closed-loop
operation indicated by the
closed-loop operation icon.
The indicated value corresponds to the control position in %.
Conguration is locked indicated by the key icon.
The fault indication icon
appears when the initialization fails.
7.8.1 Canceling initialization
The initialization can be canceled:
1. During initialization touch
: ESC blinks on the display.
2. Press
to conrm: Initialization is canceled.
This code must be conrmed by pressing
. Otherwise, the code remains active.
