Using the Up and Down buttons, change the parameter's value as desired5. 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 ModeOperating 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 fewbutton presses, it allows the user to configure a number of adjustable parameters. The LED displayhas three basic operating modes: Running Mode, Parameter-Selection Mode, and Value Mode. Eachof the three modes have specific visual indicators that allow the user to immediately determine thecurrent state or mode of the user interface. Parameter-Selection Mode and Value Mode can onlybe 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 majorityof its time in this mode. In Running Mode, the display shows the target value in the appropriate user-defined format of rate, time, or percentage. The control will continuously attempt to drive the motor atthe requested target rate. In this display mode, the Up and Down buttons increase or decrease thedisplayed target value until either the display minimum or display maximum limit is reached. Dependingon 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 forthree seconds. Once in Parameter-Selection Mode, the far left of the display will be a ‘P’. The right sideof the display will indicate the currently selected parameter number for editing purposes. Pressing theUp or Down button will increase or decrease the selected parameter number on the display. Althoughthe parameter numbers are in numerical order, some numbers are skipped. These numbers representreserved parameters that are not yet implemented and are not displayed. Once the desired parameternumber is displayed, a press of the Enter button will change the display to the Value Mode. When inParameter-Selection Mode, pressing the Enter button with parameter 0 selected will cause theunit 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 twodots which form the colon, between digits two and three, will alternately flash (one, then the other) toinform the user that a parameter’s value is being edited. Pressing the Up or Down button increases ordecreases the selected parameter’s value. See the Software Parameters for a list of allowable valuesand ranges. Value changes take effect immediately. For example, when scrolling through the alarmoutput conditions, the relay will activate as the always-active selection is passed. Once the desired valueis showing in the display window, pressing the Enter button again will return to Parameter-SelectionMode. The new value is not saved in permanent memory until the Enter button is pressed. Removingpower from the unit while in Value Mode may result in the specified new value being lost. |
