Totalizer #1 Menu

Use the Totalizer Menu to configure and monitor the totalizer. The totalizer output is a 50 millisecond (.05 second) positive pulse (relay closed for 50 milliseconds). The totalizer cannot operate faster than one pulse every 100 millisecond (.1 second). A good rule to follow is to set the unit per pulse value equal to the maximum flow in the same units per second. This will limit the pulse to no faster than one pulse every second.

Example for Setting the Totalizer

The following shows how to set the totalizer to track mass flow in kg/sec. (All outputs are disabled while using the Setup Menus.)

First, set the desired units of measurement:

1.Use ￿￿ keys to move to the Units Menu (see to page 3-9).

2.Press ￿ key until Mass Flow Unit appears. Press ENTER.

3.Press ￿ key until kg appears in the numerator. Press ￿ key to move the underline cursor to the denominator. Press the ￿ key until sec appears in the denominator. Press ENTER to select.

4.Press ￿ key until Units Menu appears.

Second, set the pulse output:

1.Use ￿￿ keys to move to the Totalizer Menu.

2.Press the ￿ key until Totaling appears.

3.Press ENTER and press the ￿ key to select Mass. Press ENTER.

4.Press ￿ key to set the pulse output in the units you have selected for mass flow of kg/sec. Press ENTER and use ￿￿￿￿ keys to set the pulse value equal to the maximum flow in the same units per second. Press ENTER.

5.To reset the totalizer, press ￿ key until Reset Total? appears. Press ENTER and the ￿ key to reset the totalizer if desired. Press ENTER.

6.Press the EXIT key and answer YES to permanently save your changes.
