Press INIT key to start initialization.
The initialization procedure may
take several minutes, depending on
the actuator size, as the valve moves
through its entire travel/angle of ro-
tation range.
Positioners with EXPERT
tions automatically start plotting the refer-
ence graphs after the initialization process
has been completed (see note at the bottom
of page 50).
MAN – Initialization based on a manually
selected range
(with default upper x-range value preset by
manual adjustment)
Initialization mode same as NOM , but to
start up valves with unknown nominal range
In this mode, the positioner expects the con-
trol valve to be moved manually to the de-
sired OPEN position prior to enabling the
initialization procedure.
The upper range travel/angle of rotation
value is adjusted using the rotary pushbutton.
The positioner uses this OPEN position and
CLOSED position to calculate the differential
travel/angle and accepts it as the operating
range with the lower x-range value and up-
per x-range value being the limits.
