Rosemount 4500
NONPV LIMIT
A secondary variable read by the transmitter is outside of the transmitter’s
range.
CURR SAT
The pressure read by the module is outside of the specified range, and the
analog output has been driven to saturation levels.
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
or AMS to interrogate and reconfigure the appropriate portion of the
transmitter memory. This warning does not effect the transmitter operation.
Contact Rosemount Customer Central at 800-999-9307 if you need
assistance.
PRESS ALERT
A HART alert when the process variable read by the transmitter is outside of
the user set alert limits.
TEMP ALERT
A HART alert when the secondary temperature variable read by the
transmitter is outside of the user set alert limits.
Operation
Normal operation messages appear on the LCD display to confirm actions or
inform you of transmitter status. Operation messages are displayed with other
transmitter information, and warrant no action to correct or alter the
transmitter settings.
ZERO PASS
The zero value, set with the local zero adjustment button, has been accepted
by the transmitter, and the output should change to 4 mA.
ZERO FAIL
The zero value, set with the local zero adjustment button, exceeds the
maximum range down allowed for a particular range, or the pressure sensed
by the transmitter exceeds the sensor limits.
SPAN PASS
The span value, set with the local span adjustment button, has been accepted
by the transmitter, and the output should change to 20 mA.
