ELECTRA-flo G5 Transmitter Thermal Airflow & Temperature Measurement System 1015-3 - 07/18
23
Manual
Selecting Manual will allow inputting of externally determined Gain (K) and Exponent (E) values,
where:
Flow (corrected) = K x Flow (uncorrected) ^ E
SERVICE MENU
Total System Scan
Displays the current status of all of the system sensors, thus
allowing the user to quickly verify all is operating properly.
Expected
(white) and
Enabled
(green) sensor values should be
the same unless sensors have been intentionally
Disabled
(red).
See below for sensor control. If
Missing
(yellow) is at a value
other than zero, the transmitter is not communicating with the
associated node.
Sensor Control / Sensor Data Scan / Sensor Alert Scan
Sensor Control
An enabled sensor will report measurement data to the
ELECTRA-flo G5 transmitter. This is the default condition
after initially powering the system. A disabled sensor
will not report measurement data to the ELECTRA-flo
G5 transmitter. Disabled sensors may have a malfunction
that causes this condition. It may also be desirable to
intentionally disable a sensor for troubleshooting purposes.
A known bad or suspect sensor can be disabled to remove
it from the flow and temperature averages until it can be
evaluated and/or repaired if necessary.
Sensor Data Scan
Displays sensor number (
Sen
), power input to sensors
(
PWM
), temperature difference between flow and
temperature sensors (
DELTAt
), velocity (
FPM
), flow
temperature sensor (
FLOWt
) and the reference temperature
sensor (
REFt
).
This data display screen can be used to further evaluate and
troubleshoot the system performance and the application
characteristics; e.g., the individual sensor velocities and
temperatures will provide comprehensive data regarding
the flow profile measured.
