In the Run Mode, the flowmeter performs flow measurement, updates the 4 to 20 mA
and pulse signal outputs, displays and logs data and performs process control actions
according to the active configuration.
The flowmeter indicates that it is in the Run Mode as follows:
The flowmeter remains in the Run Mode until it is powered down, the user takes an
action to go to Setup Mode or, exceptionally, an error occurs and the flowmeter goes to
the Faulted State. The user can command the flowmeter to Setup Mode by pressing
the motherboard setup button or changing the position of the measurement mode switch
between Transit Time and Doppler. If the Model S3 Display or the Communications
PC Software is connected, the user can additionally press the SETUP soft button.
For a complete description of Run Mode operation, see section 7 below.
Model S1: Yellow LEDs indicate the
present “Goodness of Measurement”.
one light = poor quality
four lights = best quality
Model S2: as for Model S1, plus the Run
Mode screen appears, including an
indication of “Goodness of Measurement” on
the top line and the calculated speed of
sound in the fluid if in Transit Time
measurement mode.
Model S3: as for Model S2 (see section 1.7
for some minor differences between Model
S2 and S3 displays).

The flowmeter enters the Faulted or Warning State if:
1) The flowmeter self-test fails.
2) A configuration error is detected on exit from Setup Mode.
3) An error condition occurs during flow measurement in Run Mode or Zero
Calibration.
Faults and Warnings will be identified by two-digit error codes.
! A Fault will cause the meter to discontinue flow measurement. Note that the 4-20mA
analog output signal and 0-1000 Hz pulse output signal sets to the minimum values (fail
safe low), and all relays will respond as if in a zero flow condition.
! A Warning will not interrupt flow measurement, output signals, or relay functions.
The fault LED will flash at a rate of 2 pulses per second (ON for 250 ms and OFF for 250
ms) to count out the first digit of the error code, will then stay OFF for 1.25 second, will
then flash again
to count out the second digit and then
stay OFF for 5 seconds. The code will repeat.
Example: 8 flashes >>> 1.25 second pause >>> 1 flash >>> 5 second pause = Fault 81
at a rate of 2 pulses per second
The digit 0 will not be used, so that 81 codes
are available. The errors that can occur and their assigned codes are listed below.
