Description
The valve position limit relating to the operating range.
Alarm A1 responds when the value falls below the limit.
The valve position limit relating to the operating range.
Alarm A2 responds when the value falls below the limit.
Testing the software limit contact alarm A1 and A2 as well as the
fault alarm contact A3.
If the test is activated, the contact is switched five times.
A1/1A: Software limit contact A1 to ≥2.2 mA
A2/2A: Software limit contact A2 to ≥2.2 mA
A3/3A: Fault alarm contact A3 to ≤1.0 mA
Operating direction of the position transmitter. This indicates how
3)
the travel/angle position is assigned to the output signal i, based
on the closed position. The operating range (see Code 8) of the
valve is represented by the 4 to 20 mA signal. Values exceeding or
falling below the limits 2.4 to 21.6 mA can be represented. When
a positioner has not been connected (set point less than 3.6 mA),
the signal is 0.9 mA and 3.8 mA or 4.4 mA when the positioner
has not been initialized.
When Code 32 = YES, the position transmitter issues the value as
set in Code 30 during initialization or zero calibration.
When Code 32 = No, 4 mA is issued during a running autotune.
Select if and how faults that cause the fault alarm contact to be
switched are also indicated at the position transmitter output.
HI ix =21.6 ±0.1 mA or LO ix =2.4 ±0.1 mA
