12
A
DP signal exceeded Upper
Range Limit + 10%
This display means that the transmitter differential pressure reading
exceeds its sensor limits by more than 10%. There are two possible
causes. Either the transmitter is overpressured, or it has a sensor
malfunction. Check the pressure input to the transmitter. If an
overpressure condition exists, correct it. If not, replace the sensor
module as described on page 5-7.

W
DP signal exceeded Upper
Range Limit
No action required.

10
DP signal exceeded Upper
Operating Limit
No action required.
20407
9
DP signal is less than Lower
Operating Limit
No action required.
20407
8
W
DP signal is less than Lower
Range Limit
No action required.
20407
7
A
DP signal is less than Lower
Range Limit - 10%
This display means that the transmitter differential pressure reading
exceeds its sensor limits by more than 10%. There are two possible
causes. Either the transmitter is underpressured, or it has a sensor
malfunction. Check the pressure input to the transmitter. If an
overpressure condition exists, correct it. If not, replace the sensor
module as described on page 5-7.
20407
6
A
SP signal exceeded Upper
Range Limit + 10%
This display means that the transmitter absolute (or gage) pressure
reading exceeds its sensor limits by more than 10%. There are two
possible causes. Either the transmitter is overpressured, or it has a
sensor malfunction. Check the pressure input to the transmitter. If an
overpressure condition exists, correct it. If not, replace the sensor
module as described on page 5-7.
