Press the (OK) key.
(18) Process Alarm
(G10: P AL MODE, G11: P HI.AL VAL,
G12: P LO.AL.VAL)
The function is used to display the alarm codes
when the input pressure exceeds the specified
value within the calibration range. The same is
available for the input static pressure and the
capsule temperature on the pressure sensor.
Refer to table 4.1 Alarm Message Summary for the
specific alarm code to be generated.
• Example: Set alarm mode from OFF to HI.AL
DETECT.

Press the (OK) key.
Alarm code is generated when the
output goes beyond the value set
at G11: P HI. AL VAL.
F0348.ai
• Example: Set the higher alert value of 75 for
alarm generation.

Set 75.
Press the key twice to
enter the setting.
Press the (OK) key.
Then the alarm code “AL.35 P. HI”
is generated when the input
pressure goes beyond that value.
F0349.ai
(19) Status Output (option code AL)
This feature is used for a transistor output (open
collector) of an on/off signal according to the
status of high and low alarm limits, which are
user-configurable values as shown in (18) Process
Alarm. The status output can be assigned as
any combination of the high or low limits of the
input pressure, input static pressure, or capsule
temperature.
CAUTION
Execute DO testing by the parameter "K40:
DO test" whenever turning on the transmitter
or detecting the short interruption in order to
check that the alarm contact output is correctly
configured.
NOTE
No status output signal has been defined for a
CPU failure or hardware error. Use a 4-20 mA
signal to indicate a transmitter’s failure.
