SECTION 4.0: START-UP & COMMISSIONING FOR ONICON

INSERTION THERMAL MASS FLOW SENSORS

4.1 DISPLAY

The F-5100 ow sensor features a bright easy-to-read

graphic LED display that displays alphanumeric and

graphical data.

This display is provided with a screen saver function

that extends the life of the display. The display will

revert to the normal display mode whenever the

proximity sensor detects movement directly in front

of the sensor.

Displayed Information:

1. Energy reading used to validate calibration

2. Graphical indication of percentage of full

scale ow rate

3. Flow rate

4. Flow total

5. Fluid temperature

6. Engineering units associated with ow rate and total

7. LED’s for Power, Serial Communications, and Pulse Output

4.2 POWERING THE SENSOR

Upon initial power up, the sensor will indicate ONICON F-5000 Series along with the current

rmware version and the serial number. Two additional messages will be displayed and then the

sensor will advance to the normal run mode screen. If the sensor is installed in a pipe with ow,

the sensor will begin displaying ow and temperature data. After one minute of no movement,

the screen saver message will appear.

4.3 HELPFUL HINTS FOR START-UP & COMMISSIONING

A step-by-step procedure and companion worksheet are located on the next two pages. Please

read all installation instructions carefully before proceeding with start-up and commissioning.

Please read these helpful hints before proceeding with the start-up and commissioning procedure

on the next page.

1. ONICON ow sensors are individually calibrated for a particular application. Be sure to

verify the pipe size and location.

2. When measuring analog output signals, remember that current (mA) must be measured

in series, while voltage is measured in parallel. If the 4-20 mA signal is already connected

to a control system, you must break the connection and measure the signal in series.

3. Do not attempt to rotate the electronics enclosure on the stem.

4. Never connect power to analog or pulse output signal wires. Standard ONICON F-5100

Flow Sensors are not congured from the factory as “loop powered” devices.
