The Isolated Communications Module assembly consists of two parts: 1.
CH 9/ Downloading Events The following procedure and diagram describe how to connect the PowerVisa to a Connection setup via RS232 computer via RS232. Once the physical connection is done, see Chapter 4 Instrument Settings - Communications on page 4-10 for instructions on how to enable the PowerVisa settings to communicate with external devices. 1. Connect one end of the fiber optic cable (P/N 900406) into the Fiber Optic Serial Data Port located on the left side panel of the PowerVisa. 2.
External Communication Interface, continued Connection setup via USB The following procedure and diagram describe how to connect the PowerVisa to a computer via USB. Once the physical connection is done, see Chapter 4 Instrument Settings - Communications on page 4-10 for instructions on how to enable the PowerVisa settings to communicate with external devices. 1. Connect one end of the fiber optic cable (P/N 900406) into the Fiber Optic Serial Data Port located on the left side panel of the PowerVisa. 2.
CH 9/ Downloading Events Connection setup via Ethernet The following procedure and diagram describe how to connect the PowerVisa to a computer via Ethernet. Once the physical connection is done, see Chapter 4 Instrument Settings - Communications on page 4-10 for instructions on how to enable the PowerVisa settings to communicate with external devices. 1. Connect one end of the fiber optic cable (P/N 900406) into the Fiber Optic Serial Data Port located on the left side panel of the PowerVisa. 2.
External Communication Interface, continued Connection setup via Modem When configuring both the PowerVisa and NodeLink® for modem communications, keep in mind that the PowerVisa uses a fiber optic serial port in order to maintain electrical isolation. This means that there are no control signals available to a modem to use for handshaking and flow control. It is highly recommended that identical modems be used on the PowerVisa and the computer.
CH 9/ Downloading Events Connection setup via Modem (continued) NodeLink® uses Windows® TAPI when accessing modem communications resources. The assumption is that the Windows® modem to be used for PowerVisa communications has been properly installed prior to executing this procedure. If the modem is not on, or was not on when Windows® was started, it may be necessary to turn the modem on and restart Windows®. Windows® searches for installed serial modems at startup.
External Communication Interface, continued Connection setup via Modem (continued) Back at the PowerVisa, the last step in configuring the modem communications is to modify the modem initialization string to match the modems and chipsets being used. The goal is to configure for the following: • Restore factory settings. • Set auto-answer to answer on one or two rings (more than two rings are allowed but at some point the number of rings may start to conflict with NodeLink® timeouts).
CH 9/ Downloading Events The following is the AT initialization string for a modem using the Agere (Lucent) Modem initialization chipset: string command (continued) AT&F;S0=2;&K0;%E0;S30=6 Where AT is the modem attention command. &F instructs the modem to restore factory configuration. S0=2 turns auto-answer on and sets the number of rings to answer to two. &K0 turns flow control off. %E0 disables baud rate fall back/fall forward. S30=6 sets a 60 second inactivity modem hang up timeout.
® Downloading Events via NodeLink Downloading Events via NodeLink® NodeLink® application NodeLink® is a Windows®-based program enabling the user to download, archive and visualize (using DranView®) event-type data from a variety of Dranetz-BMI instruments including the PowerVisa. Users are strongly advised to always keep their NodeLink® and PowerVisa programs current with the latest version released by Dranetz-BMI. NodeLink V2.5 or higher is required to download events from PowerVisa firmware.
CH 9/ Downloading Events Viewing Events via DranView® DranView® with DranView® is an optional viewer and data analysis software. Data collected by the PowerVisa driver PowerVisa must first be transferred to a computer via NodeLink® so that they can be archived and/or viewed using DranView®. Users are strongly advised to always keep their DranView® and PowerVisa programs current with the latest version released by Dranetz-BMI. DranView® V5.
® DranView with HASP DranView® with HASP DranView® system requirements Installation procedure The minimum system specifications for proper installation and operation of DranView® are shown below. Users are strongly advised to follow the recommended specifications for optimal DranView® operation. The recommended specifications are especially encouraged for use with instruments that allow generation of very large databases i.e. PX5, PGPowerVisa0, and PP4300 Multi-DAQ.
CH 9/ Downloading Events Installation procedure (continued) STEP 2: There are two types of HASP available: one which can be keyed to the USB port and another which goes into the Printer or Parallel port (see figure below). Depending on type of HASP, insert in the appropriate USB port or Printer/Parallel port in the computer. Align the HASP to the keyed port and push gently to lock it in place. Keep the HASP in the port while using the DranView® application.

APPENDIX E/ Common Circuit Connections Verifying Voltage and Current Connections Introduction Correct voltage and current connection of single phase, split phase, or polyphase connections can be verified using phasor diagrams. Phasor diagrams are graphic representations that show the magnitude and angular relationship of voltage and current for each phase of a monitored connection.
Verifying Voltage and Current Connections, continued Incorrect current phasor diagram Phasor displays that show incorrect current probe connection can be corrected by reconnecting the probe so that the arrow on the probe handle points toward the load. The PowerVisa is able to display diagrams of the various wiring configurations to assist users in the selection of circuit type appropriate for their application (see Chapter 5 Start Menu - Circuit Type Selection on page 5-11).
APPENDIX E/ Common Circuit Connections Single Phase Introduction When making voltage connections to a single phase circuit use channel A differential inputs as shown below.

APPENDIX E/ Common Circuit Connections Connecting to a Potential Transformer Safety Precautions Follow the safety precautions listed on page E-3 when making all potential transformer connections. NOTE Potential Transformers are not manufactured by Dranetz-BMI and are discussed here for informational purposes only.
Connecting to a Potential Transformer Procedure Follow these steps to connect voltage probes to a potential transformer. Step Scale factor E-16 Action 1 Turn off power to the PT. 2 Connect the colored voltage probes to the channel inputs on the PowerVisa top panel. 3 Connect the colored voltage probes to the PT’s connections in accordance with the manufacturer’s instructions. 4 Turn on power to the PT. The scale factor of the PT must be accounted for in making accurate voltage measurements.
APPENDIX E/ Common Circuit Connections Connecting to a Current Transformer (CT) Safety precautions The following safety precautions apply to current transformer (CT) connections in addition to those safety precautions stated on page E-3. • Never energize a CT with the secondary open. • Never disconnect the secondary of a CT with primary energized. WARNING Refer to the manufacturer’s instructions related to the CT for exact information for connections for current monitoring.
Connecting to an Isolated Current Transformer Connecting to an Isolated Current Transformer (ISO) Introduction Low current monitoring devices made by Dranetz are called isolated current transformers or ISO boxes. The Dranetz-BMI ISO box has a 5 A current range. Safety precautions The following safety precautions apply to ISO box connections in addition to those safety precautions stated on page E-3. • Never energize an ISO box with the secondary open.
APPENDIX E/ Common Circuit Connections Connections to ISO box (continued) When connecting to CTs, the X1 terminal is normally connected to the H1 terminal of the device for correct reference phasing. Where power measurements or voltage/current phase relationships are not important, the X1 and X2 terminals may be connected in series with the output device in any line (hot or return) or in any relationship of X1/X2. Applications ISO boxes can be used in a number of ways.
Connecting to an Isolated Current Transformer, continued CAUTION DO NOT exceed current limits of the ISO box. PRECAUCION NO exceda los límites de corriente de la caja del ISO. ATTENTION NE PAS dépasser les limites d’intensité du transformateur ISO. VORSICHT Die aktuellen Grenzwerte für den ISO-Kasten sollten NICHT überschritten werden.
