PRESS LIMIT

The process variable read by the transmitter is outside of sensor range limits.

CURR FIXED

The transmitter is in multidrop mode. The analog output is not tracking
pressure changes.

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 "Transient Protection
Terminal Block" on page 2-21).

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 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 Field Communicator to
interrogate and reconfigure the appropriate portion of the transmitter memory.
This warning does not affect the transmitter operation.

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 rangedown 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.

LOCAL DSBLD

This message appears during reranging with the integral zero and span
buttons and indicates that the transmitter local zero and span adjustments
have been disabled. The adjustments may have been disabled by the
transmitter security jumper on the transmitter circuit board or through software
commands from the Field Communicator. Refer to "Transient Protection
Terminal Block" on page 2-21 for information on the position of the security
jumper, and for information on the software lockout.
