feature automatically reduces decimal resolution up to a maximum of two decimal places before rolling
over to zero and losing the total. Example: For a KFT with four decimal places, the GRAND total will
reach 9999.99 instead of 99.9999 before resetting to zero.
The FEM-03 retains both totals when the power is removed. These totals update every 25 seconds and
may not include previous flow for up to 25 seconds if flow was present when the power was removed.
STATUS ONE
The STATUS ONE screen shows:
RATE A
PL
and TOTAL A
RATE B
PL
and TOTAL B
the analog output value in mA
the analog input value (not implemented)
Rates are in Hz. and totals are in pulses. Use this screen to view the rates, totals, and output for setup or
troubleshooting.
RATIO AB/RATIO BA (FEM-03Ax only)
RATIO AB and RATIO BA indicate the direct ratio of flow A/B or flow B/A. If the ratio exceeds the ALARM
and/or WARNING limit, AL and/or WA appears on the left side of the screen. Program the parameters
for ratio monitoring, including ratio error WARNING and ALARM limit percentages, from the RATIO
screen. (See RATIO Programming on page 25.)
KFT A and KFT B Engineering Units must be the same. The RATIO display indicates NO MATCH if the A
and B KFT Engineering Units do not match. For WARNING or ALARM limits to function, you must assign
the LIMITS to the WARNING AB function. See LIMITS Programming on page 28 for information.
