The 6530 will operate from 85 to 264 VAC on a 50/60 Hz line voltage. 3.1.2 After turning the power on to the 6530, the display panel will show all segments of the VFD (series of rectangles), indicating that the 6530 is downloading the program.
Figure 3–3 Revision Display 3.1.3 When the 6530 is completely powered up and ready for use, the main menu will appear on the display. The main menu is defined by the last configuration that was used. This could include one of three different menus: phase, summation or custom.
If a circuit breaker is installed, it must be installed on the load side of the 6530 (downstream). This will keep the low impedance of the input line connected to the 6530 for surge suppression. If the line side must also contain a breaker, it should be delayed in operation to open after the load side breaker has opened.
The voltage sense lines are connected at the line side of the circuit breaker to help prevent inductive transients from entering the 6530 as the circuit breaker opens. Make sure that connections from the circuit breaker to the load are heavy conductors and short as possible.
Before the 6530 can be utilized, it must be configured and connected to the devices intended for power measurement. 3.3.1 IRING The 6530 has the ability to support a combination of up to 3 phases, therefore, there are a number of different ways in which the unit can be wired. 3.3.1.1 Hardware Connections The wiring mode selections include: •...

4. Operating Principles ANALOG PROCESSING 4.1.1 OLTS The volts signal is brought in through a precision voltage divider of 2 M and 2.4 k resistors. The gain is 0.0012. This signal is buffered (GAIN = 1) and passed into a programmable gain section. The gains for the voltage ranges are given below.
Magtrol Model 6530 Three-Phase Power Analyzer Chapter 4 – Operating Principles 4.1.2 The amps signal is brought in through a precision shunt of 0.012 ohms. This signal is amplified by 2 and passed into a programmable gain section. The gains for the voltage ranges are given below.
Chapter 4 – Operating Principles Magtrol Model 6530 Three-Phase Power Analyzer 4.1.3 XTERNAL HUNT The external shunt signal is brought in through a precision voltage divider of 9.1 k and 9.1 k resistors. The gain is 0.50. This signal is buffered and passed into a programmable gain section. The gains for the voltage ranges are given below.
Magtrol Model 6530 Three-Phase Power Analyzer Chapter 4 – Operating Principles 4.2.1 AC D ETAILS 4.2.1.1 Interrupt Driven The power analyzer will automatically update its data every 4.469 microseconds by completing the following sequence of events: • The volts input is read and checked for an over range condition. The offset is then added to the reading and the reading is negated and saved.
Page 46
Chapter 4 – Operating Principles Magtrol Model 6530 Three-Phase Power Analyzer 4.2.1.2 Main Program The main program reads that a sample is ready. Divide the V² register by 256. Store V² in a 24-bit register. (See Section 4.2.3 – Round-Off Error).
Magtrol Model 6530 Three-Phase Power Analyzer Chapter 4 – Operating Principles 4.2.2 DC D ETAILS 4.2.2.1 Interrupt Driven The power analyzer will automatically update its data every 4.469 microseconds by completing the following sequence of events: • The volts input is read and checked for an over range condition. The offset is then added to the reading and the reading is negated and saved.
Page 48
Chapter 4 – Operating Principles Magtrol Model 6530 Three-Phase Power Analyzer 4.2.2.2 Main Program The main program reads that a sample is ready. Divide the V register by 256. Store V in a 24-bit register. The result is appended to a 32 word circular buffer.
Magtrol Model 6530 Three-Phase Power Analyzer Chapter 4 – Operating Principles 4.2.3 OUND RROR The interrupt routine adds 256 56-bit squared readings. This reading is then divided by 256 and put into a 24-bit register. Some error occurs during the move to the 24-bit register. The result of the 16- bit A/D conversion is put into the high 16 bits of a 24-bit register.
NRUSH URRENT Peak hold/inrush current allows the 6530 to store the highest value read in a designated period of time, the designated period of time being the time span since the last peak hold clear occurred. Values include amps, watts and volts in any preferred combination. See Section 3.3.7.3 – Peak Hold.
Magtrol Model 6530 Three-Phase Power Analyzer Chapter 4 – Operating Principles 4.3.4 See Section 4.2.1 – AC Details 4.3.5 REST ACTOR The crest factor measurement is determined by dividing the peak measurement by the RMS measurement. See the following graph for reference.
GPIB P HANGING THE RIMARY DDRESS Each instrument serviced by the GPIB has its own primary address code, which enables the computer to obtain readings from the instrument. The factory default of the GPIB address on the 6530 is 14.
Some PC interfaces can access from one to fifteen 4-bit primary addresses. Other interfaces can access as many as thirty-one 5-bit primary addresses. The 6530 uses the 4-bit format. For setup, complete the following instructions utilizing the USER MENU control buttons.
Make sure that the 6530 and its host computer are communicating before acquiring data. 1. Make sure the primary GPIB address is set correctly for the 6530. 2. Set the input variable to 15 characters (13 variable characters and the two required data termination characters CR and LF.
Magtrol Model 6530 Three-Phase Power Analyzer Chapter 5 – Computer Controlled Operation DATA FORMAT • All measurement values are returned as an ASCII-string floating point in E notation. • The same data format will be used for both IEEE-488 and RS-232 interface. See Section 5.6 –...
Use the following information to answer the formatting questions asked when installing your GPIB software. All GPIB data acquisition systems require the use of data termination characters.
