Diagnostic Indicators
63-601 Genesis Models ED1 & ED2 Multiphase Detector
Diagnostic indicators can be mapped to multiple categories,
an example is shown in the diagram at left.
In this example, "Calibration Required" is mapped to both
Failure
the Out of Specification and Maintenance Required status
signals, and the diagnostic indicator named "High
Function Temperature" is mapped to none of the signals.
Check
Indicators that are mapped to the Failure category will nor-
Out of
mally result in a current loop alarm output. The alarm state
Specification
for typical HART instruments is configurable as high
(22 mA), Low (3.6 mA), or Hold (last value).
Maintenance Users will not have the ability to unassign certain indicators
Required
from the Failure signal category as the user interfaces will
prohibit or reject such re-assignment entries). This is to
ensure that current loop alarms are asserted in situations
NE-107
Status Signals
where the device is not able to provide measurements due to
critical failures. (For example, if the alarm selection has not
been set to Hold, or a fixed current mode is in effect.)
A default mapping of all diagnostic indicators will be applied
initially, and can be re-applied through use of a reset function.
Refer to the table below for a complete listing of diagnostic
indicators, along with their explanations, default categories,
and recommended remedies.
NOTES:

2.3.2 Diagnostic Indication Simulation

The DD and DTM allow for the ability to manipulate
diagnostic indicators. Intended as a means to verify the
configuration of the diagnostic parameters and connected
equipment, a user can manually change any indicator to
and from the active state.
1) The remedies shown in this table can also be seen on
the main electronics LCD by viewing the present status
screen when the device is in a diagnostic condition.
2) Those indicators showing failure as the default result
in an alarm condition.
