Chapter 4 DATAVIEW Software Introduction The DATAVIEW graphing and analysis program is a full function Windows based application software package. It lets you configure and run any test or recording from the computer as you can from the instrument itself. Additionally, it enhances the information captured for snapshots as it captures all the information to display and report waveforms, and harmonic spectrums of the data captured.
Chapter 4 DATAVIEW Software • Provides consistency in testing, regardless of who performs the test TIP Get Started Minimum Computer Requirements Connect the PowerPad unit to your Computer For help on software instructions, use the DATAVIEW program’s Help Menu, which is located on the menu bar. The DATAVIEW software is supplied on a CD-ROM format. The CD selfinstalls, prompting you along the way for any information that is needed.
DATAVIEW Software Start DATAVIEW Software Chapter 4 Once the serial connection between the computer and the PowerPad unit has been completed, start the DATAVIEW program. There are two ways to open and use the DATAVIEW software: • use the PowerPad unit icon.
Chapter 4 DATAVIEW Software The Quick Start dialog box contains the following options: • Configure Instrument: Opens an instrument specific control panel which displays a Configure Instrument dialog box. This dialog box lets you modify the configuration of the PowerPad unit. • Real-time Display: Opens an instrument control panel providing real-time display of measurement data. • Download Data: Opens an instrument control panel and begins the download of recorded data.
DATAVIEW Software IMPORTANT Chapter 4 The instrument must be configured for the same communications rate specified in the Connections window shown on the previous page. If it is not, then you must either select the corresponding rate or change the instrument's rate. When a serial communication link is established, the DATAVIEW program automatically identifies the instrument that it is connected to. A status screen then appears.
Chapter 4 DATAVIEW Software General Functions The general function buttons appear on several DATAVIEW program setup screens. • Re-read from PowerPad unit: Reads the current configuration of the Power-Pad attached via the serial cable. • Save to File: Saves the current configuration. This file resides on the computer's disk drive. Saving different configuration setups can be useful for future functions and tests.
DATAVIEW Software Chapter 4 • Connection Type: Single Phase, Two phase, Three-phase, three-wire Delta or Three-phase, four-wire WYE • Voltage Transformer Ratio: Sets the scale for voltage measurement in cases where measurements are on the secondary side of a transformer and the primary value needs to be displayed. • Set PowerPad unit Clock: Programs the computer's time and date into the configuration of the PowerPad unit.
Chapter 4 DATAVIEW Software Alarm Conditions Configuration The Alarm Conditions window lets you set up 10 alarm configurations. Figure 6 - Alarm Conditions Window • Hysteresis: This value for alarms is set to prevent multiple recordings of an event that goes above the threshold and a certain percentage below it at times. EXAMPLE Alarm threshold is 100V or higher, hysteresis is 1%. When the voltage goes up to 100V, the alarm condition starts.
DATAVIEW Software Chapter 4 – Athd: current total harmonic distortion – W: active power – Acf: current crest factor • Duration: The Alarm will only be recorded if the duration of the parameter meeting the threshold criteria exceeds the duration. The minimum alarm duration can be in minutes or seconds. In the case of Vrms, Urms, or Arms not using neutral current, can also be in hundredths of a second. • Disable All Alarms: This check box prevents any alarms from being captured.
Chapter 4 DATAVIEW Software For each selected harmonic data type, you can choose a range of harmonics to record from the 1st to 50th. You can further limit that range to only include odd numbers by checking the box for Odd Harmonics Only. • End Recording: Ends any recording in progress or any future recording. • Clear Entries: Clears the data entered in the new recording window. It does not cause any changes to the PowerPad unit.
DATAVIEW Software Chapter 4 Transients Configuration The Transients window allows you to set up the criteria for capturing transients. Figure 8 - Transients Window 1. Type a name for the session, up to seven characters. 2. Select the date and time to end the search for transients. 3. Select the percent deviation for voltage and current transients. The choices available from the drop down window are 1, 2, 5, 10, 20, 50, and 100% of the full scale range of measurement.
Chapter 4 DATAVIEW Software The purpose of the EN50160 standard Voltage characteristics of electricity supplied by public distribution systems is to specify the characteristics of the supply voltage with regard to the course of the curve, the voltage level, the frequency, and symmetry of the 3-phase network at the interconnecting point to the customer. The goal is to determine limiting values for regular operating conditions.
DATAVIEW Software Real-time Windows Chapter 4 When your setup is completed, you can display different views on the screen of real time data and waveforms. Waveform, Harmonic Bar and Harmonic Text Figure 10 - Real-time Data On each screen, you can: • Select the type of data to see • Stop the update with the Hold function • Print the screen selected • Save it to disk. Download Data to Database From the Instrument menu, select data to download the data recorded to the PowerPad unit. 1.
Chapter 4 DATAVIEW Software Photographs The Photographs window displays a list of photographs taken on the PowerPad unit. It shows the date and time when the camera button was pressed. When Download to Database is selected, it shows the waveforms, power data, and Bitmap image of the PowerPad unit screen from the time the camera button was pressed. TIP 64 Snapshots can only be initiated by using the Camera button PowerPad unit itself, not by DATAVIEW.
DATAVIEW Software Chapter 4 Alarms The Alarms window displays a list of alarms recorded on the PowerPad unit. A subset of the list, can be viewed by the phase of the triggering event. Alarms can be selected and downloaded to a database. The downloaded alarms contain no more information than is shown in the screen display.
Chapter 4 DATAVIEW Software Transients The Transients window displays transients stored on the PowerPad unit. It shows the number and name of the recording, and the time it began and ended. The selected transients can either be downloaded or deleted. The downloaded result contains four waveforms.
DATAVIEW Software Chapter 4 Power/Energy The Power/Energy window displays accumulated power and energy data. Accumulated energy data can be started or stopped, and the results can be download to a database, and viewed on the screen, selected by phase. The data for all available phases are downloaded to a database, not just that TIP shown on the screen. EN50160 The EN50160 window displays recorded tests that can be downloaded and analyzed.
Chapter 4 DATAVIEW Software Session Properties After downloading the data that is selected, the Session Properties window opens, which consists of the following: • Operator Information: Information associated with the person and company conducting the test. • Site Information: Information about the site itself. • Comments: A place where information can be typed, such as, further descriptive analysis of the test, the test results, or reasons for running the test.
Chapter 5 Maintenance Use only factory specified replacement parts. Rockwell Automation is not held responsible for any accident, incident, or malfunction following a repair done other than by its service center or by an approved repair center. Recharging and Changing the Battery The battery is automatically charged when the unit is connected to AC power.
