Rate, Time, and Counter Modes Explained

In Rate Mode, the DM8000 measures the input frequency, converts it to the user-deﬁ ned units, and

displays the rate in the display window of the user interface. Most applications utilize rate mode and

display in units such as gallons-per-minute, feet-per-second, and RPM.

In Time Mode, the DM8000 measures the input frequency, converts it to the user-deﬁ ned time units,

and displays the time in the display window. This mode is most-commonly used in time-sensitive

processes such as conveyor ovens and plating applications.

In Counter Modes, the DM8000 counts each incoming pulse, scales it per the user-deﬁ ned ratios,

and displays the count in the display window. Typical counting applications include linear material

measurement, cycle counters, and liquid volume measurement.

In Rate or Time with Direction modes a quadrature pick-up is required. In these modes it will perform

the same functions as above under Rate or Time modes but the FWD and REV annunciators will be

used to indicate the direction that the pick-up is turning. Please refer to the FORWARD / REVERSE -

TIMING CHARTS for more information on the timing of the quadrature pick-up.

In Dual Rate or Dual Time modes two signals are needed, one on S1 and one on S2. In these modes

it will perform the same functions as above under Rate or Time modes but the S1 and S2 annunciators

will be used to indicate which signal is being viewed. In order to switch between the two signals the

Up and Down buttons are used; Down for S1 and Up for S2.

2. Using the Up and Down buttons, select the desired parameter number to view or edit

3. Press the Enter button to change the value of the parameter

4. Using the Up and Down buttons, change the parameter's value as desired

5. Press the Enter button to permanently save the changes (Return to Parameter-Selection Mode)

6. Select parameter zero and press the Enter button to return to Running Mode

Operating the User Interface (The Long Story)

Although the DM8000 user interface is very versatile, it is also simple to setup and operate. With just

a few button presses, it allows the user to conﬁ gure a number of adjustable parameters. The LED

display has three basic operating modes: Running Mode, Parameter-Selection Mode, and Value Mode.

Each of the three modes have speciﬁ c visual indicators that allow the user to immediately determine

the current state or mode of the user interface. Parameter-Selection Mode and Value Mode can only

be entered if the Program Enable jumper is in the "On" position.
