(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

Then the alarm code “AL.35 P. HI”
is generated when the input
pressure goes beyond that value.

(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.
