Description
Alarm A1 responds when the value falls below the limit.
Software limit value A1 is displayed or can be changed in relation to
the operating range.
The setting has no effect when an inductive limit switch is installed.
Alarm A2 responds when the value falls below the limit.
Software limit value A2 is displayed or can be changed in relation to
the operating range.
Testing the software limit switch alarm A1 and A2 as well as the fault
alarm contact A3.
If the test is activated, the contact is switched five times.
RUN 1/1 RUN: software limit switch A1 to ≥2.2 mA
RUN 2/2 RUN: software limit switch A2 to ≥2.2 mA
RUN 3/3 RUN: fault alarm contact A3 to ≤1.0 mA
Operating direction of the position transmitter: it indicates assign-
3)
ment between travel/angle position and output signal i based on
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 when the positioner has
not been initialized. When YES is set in Code 32, the position trans-
mitter issues the value as per Code 30 during initialization or zero
calibration. When No is set in Code 32, 4 mA is issued while cali-
bration is in progress.
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
