d. Software Seal
(D58: SOFTWR SEAL)
When you lose the password that has been registered, it
is possible to release the write protect function by
using general password, “YOKOGAWA.” When the
password is used, the status shown in the parameter of
D58: SOFTWR SEAL is changed from
KEEP
to
BREAK
. The status returns to
KEEP
by entering a
newly set password at D56: WRT ENABLE.
(12) Output Status Setup when a Hardware
Error Occurs (D26: ERROR OUT)
This parameter allows the setting of the output status
when a hardware error occurs. The following selections
are available.
(a) BURNOUT DIR; Outputs the corresponding values
of 110% or –5% of output signals according to the
setting by burnout direction switch (BO) on the
CPU board.
(b) HOLD; Outputs the last value held before the error
occurred.
Note: A hardware error means CAP.ERR of AL.01 or AMP.ERR of
AL.02 which are shown in table 4.2 Alarm Message
Summary.
• Example: Set the output status to
HOLD
when
a hardware error occurs.

(13) Bi-directional Flow Measurement Setup
(E30: BI DIRE MODE)
(a) This parameter enables selection of 50% output at
an input of 0 kPa.
Procedure is shown in the figure below.
(b) Combining this with
C40: OUTPUT MODE
provides a square root output computed indepen-
dently for 0% to 50% output and for 50% to 100%
output.
• Example: If measurement range is 0 to 10 kPa
(LRV=0 kPa, URV=10 kPa)
The measurement range changes to –10 to 0 to 10 kPa
(output 0% to 50% to 100).
Note that
C21: PRES LRV
and
C22: PRES URV
are not changed.
