(8) Unit Setup for Displayed Static Pressure
(D31: STAT.P.UNIT)
Follow the procedure below to change the static
pressure units.
Changing this parameter changes the unit for the A30:
STATIC PRESS (static pressure) display.
• Example: Change the static pressure unit from
kgf/cm

(9) Operation Mode Setup
(D40: REV OUTPUT)
This parameter allows the direction of the 4 to 20 mA
output to be reversed with respect to input. Follow the
procedure below to make this change.
• Example: Change 4 to 20 mA output to 20 to
4 mA output.

(10) Impulse Line Connection Orientation
Setup (D45: H/L SWAP)
This parameter allows the impulse line connections to
be reversed at the transmitter. Follow the figure below
to make this change.
• Example: Change the impulse line connection
from high pressure on right to high
pressure on left.

(11) Output Status Display/Setup when a CPU
Failure (D52: BURN OUT)
This parameter displays the status of 4 to 20 mA DC
output if a CPU failure occurs. In case of a failure,
communication is disabled.
Setting of HIGH or LOW is enabled. This is done with
the pin (CN4) on the CPU assembly. See Chapter 3 for
details.
Standard specifications
The parameter is set to HIGH. If a failure, the transmit-
ter outputs the signal of 110% or higher. The parameter
D53: ERROR OUT is set to HIGH from the factory.
Optional code/C1
The parameter is set to LOW. If a failure, output which
is –5% or lower is generated. The parameter D53:
ERROR OUT is set to LOW from the factory.
• Example: Standard specifications
pin (CN4) position: H
D52: BURN OUT
HIGH

(12) Output Status Setup when a Hardware
Error Occurs (D53: ERROR OUT)
This parameter allows the setting of the output status
when a hardware error occurs. The following three
selections are available.
(a) HOLD; Outputs the last value held before the error
occurred.
(b) HIGH; Outputs an output of 110% when an error
has occurred.
(c) LOW; Outputs an output of –5% when an error has
occurred.
Note: A hardware error means CAP MODULE FAULT of Er.01 or
AMP MODULE FAULT of Er. 02 which are shown in 7.5.2
“Errors and Countermeasures.”)
• Example: Set the output status to LOW when
a hardware error occurs.
