Default

Configuration

“0” = Disabled,

“1” = Enabled

Primary

Value

Degraded

The PV is outside the

operating range of the

transmitter.

PV status will

go

UNCERTAIN.

The Instrument

Pressure may be

too High or too

Low. Confirm that

it is within the

Operating Range

of the Transmitter.

"The PV is outside the operating range

of the transmitter.

1. Confirm that the process pressure is

within the operating range of the

transmitter.

2. If the pressure applied to the device is

within the limits then there is a pressure

sensor malfunction. Replace the Sensor

Module."

Secondary

Value

Degraded

The instrument body

temperature is outside

the operating range of

the transmitter.

PV status will

go

UNCERTAIN.

The Instrument

Body Temperature

may be too Hot or

too Cold. Confirm

that it is within the

Operating Range

of the Transmitter.

"The instrument body temperature is

outside the operating range of the

transmitter.

1. If the ambient temperature of the

instrument is within the limits then there

is temperature sensor malfunction.

Replace the Sensor Module."

Module

Memory

Warning

There is a non-critical

integrity check failure in

the sensor EEPROM

memory. This warning

does not affect device

performance.

Device may

lose non-critical

data (serial

number,

materials of

construction,

etc…).

Replace the

Sensor Module at

the next scheduled

Maintenance.

"There is a non-critical integrity check

failure in the sensor EEPROM Memory.

This warning does not affect device

performance.

1. Replace the Sensor Module at the

next scheduled maintenance."

Plugged

Impulse Line

Detected

The device diagnostics

has reported a plugged

impulse line(s).

1. This will

have not affect

of the device.

Or 2. If this is

configured to

affect PV status

then PV status

will go

UNCERTAIN.

Check the Device

Impulse Line(s).

"The device diagnostics has reported a

plugged impulse line(s).

1. Check the device impulse line(s).

2. Check for correct configuration of the

impulse line parameters in the

diagnostics transducer block."
