Code
1 and blink.
Turn until the pressure in the positioner
builds up, and the control valve moves to its
final positions so that the travel/angle of ro
-
tation can be checked.
The angle of rotation on the back of the
positioner is indicated. A horizontal lever
(mid position) is equal to 0°.
To ensure the positioner is working prop-
erly, the outer bar elements may not blink
while the valve is moving through the oper-
ating range.
Exit Code 1 by pressing the rotary
pushbutton ( ).
The permissible range has been exceeded
when the displayed angle is greater than
30°, and the outer right or left bar element
blinks.
The positioner changes to the fail-safe posi
-
tion (
SAFE ).
After canceling the fail-safe position (SAFE)
(see section 8.2.2) it is absolutely necessary
to check the lever and pin position as de
-
scribed in section 4.
WARNING!
To avoid personal injury or property dam
-
age caused by the supply air or electrical
auxiliary power, disconnect the supply air
and electrical auxiliary power (bus line) be
-
fore exchanging the lever or changing the
pin position.
7.6 Initialization
WARNING!
During initialization, the control valve moves
through its entire travel/angle of rotation
range. Therefore, do not start the initializa
-
tion procedure while a process is running,
but only during start-up when all shut-off
valves are closed.
Before starting initialization, check the maxi-
mum permissible signal pressure of the con-
trol valve. During initialization, the
positioner issues an output signal pressure
up to the maximum supply pressure sup-
plied. If necessary, limit the signal pressure
by connecting an upstream pressure reduc-
ing valve.
NOTICE
After the positioner has been mounted on to
another actuator or its mounting location
has been changed and prior to
re-initializing the positioner, the positioner
needs to be reset to its basic setting (default
values). Refer to section 7.8.
During initialization the positioner adapts it
-
self optimally to the friction conditions and
the signal pressure demand of the control
valve. The type and extent of self-adaptation
depends on the set initialization mode:
