3.3.15 Test Output, Simulation, and Squawk
NOTE
Fixed current output, DO Test, and Device
Variable Simulation Function continue for a given
holding time, then is released automatically.
Even if the HART configuration tool power
supply is turned off or the communication cable
is disconnected, the test output will continue for
that time.
The holding time can be selected from 10 min*,
30 min, 60 min, 3 hour, 6 hour or 12 hour.
*: Default value.

(1) Fixed current output
This feature can be used to output a fixed current
(or voltage) for loop checks. The available range for
test output depend on the settings for the
AO lower
limit
and
AO upper limit
parameters, whose limit
is from 3.6 mA or 0.9 V (-2.5%) to 21.6 mA or 5.4 V
(110%).
Refer to the subsection 3.3.2 about the setting of
AO lower limit
and
AO upper limit
.
While this function works, “TEST” is displayed on
the integral indicator.
Setting by DD and DTM (EJX HART 5 DTM
based on FDT1.2)
Call up the test output parameter (Loop test) and
select the output signal.
