Fig 3.7

You can change this value to that desired for your application, and you can also determine the condition that you wish it to

operate, e.g., above or below the programmed value, between or outside the programmed values. Note that when either of

these latter two options are selected, a second value window will appear.

Beneath this you will see an option to select the relay's sensitivity in detecting the programmed condition at which you wish

it to activate; the default is set to 'low' . It is recommended that you do not adjust this unless you need the relay to operate

immediately when the flow rate hits the programmed level. Please note, however, that the equipment connected to the relay

may experience rapid turning on and off when the flow rate is turbulent and is close to the programmed alarm value.

Finally, you may also wish to change the appearance of the Display when the Alarm condition is met. For example, if you

wanted to make the screen flash red when the flow rate is above a certain value such as a high flow rate, you can achieve

this by checking the 'Change Backlight' box and selecting the desired appearance.

When all changes have been made, it is essential that you click on 'APM' in the menu at the top of the screen, and then

click on the dropdown option 'Write Configuration to APM' .

Before disconnecting the Type A to Type B cable between your PC and the Display, you may wish to save your configuration

settings. To do so, click on 'File' at the top-left of the Configurator screen, and then click on 'Save Configuration File' from the

dropdown menu. In the 'Save As' dialog box, navigate to the location that you wish to save the file, and give it a Filename

before clicking on the 'Save' button.

In this screen, you can program:

of this screen, you can program the

values, it will operate when the flow rate

is above 25 GPM.
