9.7 Self-diagnostic Functions

TheHARTcongurationtoolcanbeusedtorun

self-diagnostics on a device and check for incorrect

data settings.

(1) Using DD and DTM

The Self test and Status commands are available

for self-diagnostics. When Self test is run, the

display unit shows an error code and alarm

message if the device detects any illegal parameter

settings or functional faults.

• Procedure to call up the Self test display

[Root Menu]→Diagnosis/Service→Test/Status→

Self test

If no error is detected, “Self test OK” is displayed on

thecongurationtool.

Ifthespecicdiagnosticitemisknownforthe

check, you can directly call up the item by using the

Status command.

The status is categorized from 1 to 7. For details,

refer to the table at the end of 9.9.

Status group 1.

If no error is detected, “Off” is displayed on the

congurationtool.

If there is an error, “On” is displayed on the

congurationtool,andacountermeasureforthat

error is necessary.

Example of display: Span > 10 m/s On

Span < 0.3 m/s Off

TTL > 10000 p/s Off

TTL < 0.0001 p/s Off

4-20 Lmt Err Off

9.8.1 Test Output, Simulation, and Squawk

NOTE

Fixed current output, Flow Simulation Mode,

and Device Variable Simulation Function

continue for a given holding time, then is

released automatically. Even if the HART

conguration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.

4mA Output a 4mA DC signal

20mA Output a 20mA DC signal

Other Set a desired output signal value

End Exit

(2) Device Variable Simulation Function

Using the simulation function, the output signal can

beconrmedbysettinganyvalueandstatustothe

selected device variable.

Call up the parameter and follow the message

shown.

After completing the step 5, the simulation starts.

The indicator shows output and warning (93: Dev
