D-100 Flow Display Manual 10/14 - 0634-14 / 18340 Page 25

4.6 COMMISSIONING

Upon initial installation, it is strongly recommended that both the D-100 and its associated ow

meter be commissioned to ensure that they are properly installed and functioning correctly.

This process involves verifying the mechanical installation, measuring ow signals and then

comparing these measurements to the specied installation and operating parameters listed on

the certicate of calibration provided with the display. The data collected during this initial

commissioning process will then serve as baseline data for periodic revalidation of the meter

operation.

COMMISSIONING PROCEDURE

Please read all installation instructions carefully before

proceeding. Wiring diagrams are located in this manual.

Use the display Certicate of Calibration to verify that

the specied installation & operating parameters match

the actual conditions at the location where the display

is installed. A worksheet for checking these steps and

recording measured values is located on the following

page.

1. Conrm that the D-100 is being

installed with the correct ow meter

and any optional sensors.

Check the label inside the front cover of the D-100 and conrm that the

serial numbers match the serial numbers of the ow meter and any optional

sensors being used.

2. Conrm that the D-100 is being

installed in accordance with

Sections 1.5 and 3.1 of this manual.

Conrm that the installation location is not in direct sunlight and is

removed from sources of strong electrical interference. The display should

be mounted on a vibration-free surface where it will be protected against

spraying, splashing and the seepage of water.

3. Conrm the pipe diameter and pipe

material.

Conrm that the ow meter is tagged for the pipe diameter and material in

which it is to be installed and that this information matches the information

provided on the display certicate of calibration. When in doubt, measure

the circumference of the pipe.

Pipe O.D. = (circumference / 3.14) – (insulation thickness x 2)

4. Conrm that the ow meter installation

conforms to the requirements specied

in the ow meter installation manual.

Verify that the ow meter is installed in a location with enough straight

unobstructed run upstream and downstream of the pipe. Also verify that

the ow meter is properly oriented with respect to ow direction, and for

insertion meters ensure that the meter is installed to the correct insertion

depth.

5. Conrm that any optional sensors are

properly installed.

Verify that any optional sensors connected to the D-100 are installed in

accordance with the manufacturer’s installation instructions. Also conrm

that the sensor output matches the information shown on the D-100 C of C.

6. Conrm that the correct supply voltage

has been provided.

Verify and measure the AC input voltage to the display.

Input voltages should be within the following ranges.

24VAC: 20 – 28VAC

24VAC when connected to an F-3500 and the D-100 is equipped with a

multi-analog board: 21.6 – 28VAC

120VAC: 108 - 132 VAC

230VAC: 207 - 253 VAC

In order to proceed with the following steps, the display, ow meter and optional sensors must be operating and there must

be ow in the pipes. Flow signal readings should be taken while holding the ow rate constant, if possible.

7. Select the ow rate page on the D-100

front panel display.

Scroll through the D-100 display pages and select the ow rate page. Verify

that the engineering units and multiplier shown match those on the C of C.

8. Note and record the ow reading. Note the displayed ow rate and conrm that it is within the expected

range. For D-100 displays connected to ow meters with integral displays,

conrm that the ow readings shown on the two displays agree. Record the

ow rates.
