Introduction
The DP4 digital potentiometer is a compact, microprocessor-based unit capable of being either field or factory configured for a number of industry's user-interface needs. The DP4 allows the user to adjust the displayed value via the front-panel push buttons. As the displayed value is raised or lowered, the output signal from the DP4 follows proportionally according to the unit's configuration. These units supports both unipolar and bipolar output and are capable of automatically inverting, scaling, and offsetting the output as needed. Utilizing Dart's new modular bus design techniques, the DP4 series is ideal for volume OEM applications requiring specialized inputs and outputs. Contact Dart Controls' Sales Department for details. This flexibility makes the DP4 series ideal for applications such as:
Water and Waste Treatment Systems
Conveyor Oven Controllers
Synchronized Conveyor Lines
Its durable 1/8 DIN aluminum housings can be easily mounted in a panel or control cabinet. New optional pluggable terminal block allows the installer to quickly install or replace units without the hassle of physically removing and reattaching wires. The units can be ordered with either standard Europeanstyle terminal block or optional “pluggable” connector.

-1 Option Wiring
The -1 option board is a module which allows external up and down push buttons to be wired to the unit. These buttons operate exactly like the Up and Down buttons on the user interface. This module is commonly used to allow PLCs or hand-held pendants to operate the front-panel remotely. Wires for the external buttons are attached via a 3mm European terminal block on the -1 option board. The buttons are activated by shorting the terminal labeled Com to either the Up or Down terminal.

Basic Operating Information
The DP4 digital potentiometer is a panel-mount digital-to-analog user interface. Put simply, it allows the user to adjust the displayed value via push buttons on the front panel; and, outputs a proportional signal according to its configuration. It can be configured to work with both single and bidirectional partner drives. It also supports both unipolar and bipolar output supplies.
The DP4 can display values in rate and time formats. In Rate mode, output units such as Gallons-per- Minutes, RPM, and Percent are possible with just a few minor adjustments. In Time mode, output units such as Hours:Minutes (HH:MM), Minutes:Seconds (MM:SS), and Seconds:Ticks (SS:TT) are supported. In Time modes, the output will be inversely proportional to the displayed value in order to represent a programmable process time.
See the application examples in this manual for additional information on how the DP4 can be configured.

How to Change a Parameter's Value (The Short Story)
1.Hold down the Enter button until Parameter-Selection Mode is entered
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 DP4 user interface is very versatile, it is also simple to setup and operate. With just a few button presses, it allows the user to configure 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 specific 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.
Running Mode is the default display of the unit when power is applied. The DP4 will spend the majority of its time in this mode. In Running Mode, the display shows the target value in the appropriate userdefined format of rate, time, or percentage. The control will continuously attempt to drive the motor at the requested target rate. In this display mode, the Up and Down buttons increase or decrease the displayed target value until either the display minimum or display maximum limit is reached. Depending on the alarm configuration, these buttons may also serve as an alarm-silence or alarm-reset button. Example displays for rate, time, and follower operating modes are 13.60, 45:30, and 9301.
Parameter-Selection Mode can be entered by simply pressing and holding the Enter button down for three seconds. Once in Parameter-Selection Mode, the far left of the display will be a ‘P’. The right side of the display will indicate the currently selected parameter number for editing purposes. Pressing the Up or Down button will increase or decrease the selected parameter number on the display. Although the parameter numbers are in numerical order, some numbers are skipped. These numbers represent reserved parameters that are not yet implemented and are not displayed. Once the desired parameter number is displayed, a press of the Enter button will change the display to the Value Mode. When in
Parameter-Selection Mode, pressing the Enter button with parameter 0 selected will cause the unit to return to Running Mode. Example displays for Parameter-Selection Mode are P 1, P 12, and P 54. See the Software Parameters for a list of available parameters.
Value Mode is used to modify the value of the selected parameter. When in Value Mode, the two dots which form the colon, between digits two and three, will alternately flash (one, then the other) to inform the user that a parameter’s value is being edited. Pressing the Up or Down button increases or decreases the selected parameter’s value. See the Software Parameters for a list of allowable values and ranges. Value changes take effect immediately. For example, when scrolling through the alarm output conditions, the relay will activate as the always-active selection is passed. Once the desired value is showing in the display window, pressing the Enter button again will return to ParameterSelection Mode. The new value is not saved in permanent memory until the Enter button is pressed. Removing power from the unit while in Value Mode may result in the specified new value being lost.
