Description
Important
! Codes with marked with an asterisk (*) must be enabled with Code 3 prior to configuration.
11* Upper x-limit
50.0 to 120.0 [100] % of
the operating range
OFF, ESC
Limitation of the travel/angle of rotation upwards to the entered
value, the characteristic is not adapted.
Example: In some applications, it is better to limit the valve travel,
e.g. if a certain minimum medium flow is required or a maximum
flow must not be reached.
The lower limit must be adjusted with Code 10, and the upper
limit with Code 11.
If a tight-closing function has been set up, it has priority over the
travel limitation!
When set to OFF, the valve can be opened past the nominal
travel with a reference variable outside of the 0 to 100 % range.
14* Final position w <
0.0 to 49.9 [1.0] %
of the span adjusted via
Code 12/13
OFF, ESC
If w approaches the percentage adjusted at the final value that
causes the valve to close, the actuator is immediately completely
vented (with AIR TO OPEN) or filled with air (with AIR TO
CLOSE).
This action always lead to maximum tight-closing of the valve.
Codes 14/15 have priority over Codes 8/9/10/11.
Codes 21/22 have priority over Codes 14/15.
15* Final position w >
50.0 to 100.0 %
of the span adjusted via
Code 12/13
[OFF], ESC
If w approaches the percentage adjusted at the final value that
causes the valve to open, the actuator is immediately completely
filled with air (with AIR TO OPEN) or vented (with AIR TO
CLOSE).
This action always lead to the valve being completely opened.
Codes 14/15 have priority over Codes 8/9/10/11.
Codes 21/22 have priority over Codes 14/15.
Example: Set the final position w > to 99 % for three-way valves.
16* Pressure limit
1.4 2.4 3.7 bar
[OFF], ESC
The pressure limit determined during initialization is displayed
and can be changed. (Only for position valve closed/AIR TO
OPEN, for valve open/AIR TO CLOSE, always set it to
OFF
after
initialization, i.e. complete supply pressure to the actuator. The
signal pressure can also be limited already prior to initialization
to protect against impermissibly high actuating forces).
Note
: After changing a pressure limit already set, the actuator
must be vented once (e.g. by selecting the fail-safe position over
Code 0).
The pressure limit must always be set to
OFF
after initialization
for double-acting actuators.
