Reference Manual

00809-0100-4808, Rev CA June 2008

Some non-volatile memory faults are user-addressable. Use a HART Communicator to diagnose the error and determine if it is repairable. Any error message that ends in “FACTORY” is not repairable. In cases of non user-addressable errors, you must replace the transmitter. Contact Rosemount Nuclear Instruments Inc. at (952) 949-5210 if you need assistance.

 

FAIL ELECT

 

The transmitter electronics board is malfunctioning due to an internal fault.

 

Some of the FAIL ELECT errors are user-addressable. Use a HART

 

Communicator to diagnose the error and determine if it is repairable. Any

 

error message that ends in “FACTORY” is not repairable. In cases of non

 

user-repairable errors, you must replace the transmitter. Contact Rosemount

 

Nuclear Instruments, Inc. at (952) 949-5210 if you need assistance.

 

FAIL CONFIG

 

A memory fault has been detected in a location that could effect transmitter

 

operation, and is user-addressable. To correct this problem, use a HART

 

Communicator to interrogate and reconfigure the appropriate portion of the

 

transmitter memory. Contact Rosemount Nuclear Instruments, Inc. at

 

(952) 949-5210 if you need assistance.

Warnings

Warnings appear on the LCD meter display to alert you of user-repairable

 

problems with the transmitter, or current transmitter operations. Warnings

 

appear alternately with other transmitter information until the warning

 

condition is corrected or the transmitter completes the operation that warrants

 

the warning message.

 

PRESS LIMIT

 

The process variable read by the transmitter is outside of the transmitter’s

 

range.

 

TEMP LIMIT

 

The secondary temperature variable read by the transmitter is outside of the

 

transmitter’s range.

 

CURR SATURD

 

The pressure read by the module is outside of the specified range, and the

 

analog output has been driven to saturation levels. See “Failure Mode Alarm”

 

in Section 2.

 

LOOP TEST

 

A loop test is in progress. During a loop test or 4–20 mA trim, the analog

 

output is set to a fixed value. The meter display alternates between the

 

current selected in milliamps and “LOOP TEST.”

 

XMTR INFO

 

A non-volatile memory fault has been detected in the transmitter memory by

 

the memory verification routine. The memory fault is in a location containing

 

transmitter information. To correct this problem, use a HART Communicator to

 

interrogate and reconfigure the appropriate portion of the transmitter memory.

 

This warning does not effect the transmitter operation. Contact Rosemount
