HAZARD OF ELECTRIC SHOCK, EXPLOSION, OR ARC FLASH? Apply appropriate personal protective equipment (PPE) and follow safe electrical work practices. In the USA, see NFPA 70E.? Only qualified electrical workers should install this equipment. Such work should be performed only after reading this entire set of instructions.?

provided by the equipment may be impaired.? NEVER work alone.? Before performing visual inspections, tests, or maintenance on this equipment, disconnect all sources of electric power. Assume that all circuits are live until they have been completely de- energized, tested, and tagged. Pay particular attention to the design of the power system. Consider all sources of power, including the possibility of backfeeding. ? Turn off all power supplying the power meter and the equipment in which it is installed before working on it.? Always use a properly rated voltage sensing device to confirm that all power is off.? Before closing all covers and doors, carefully inspect the work area for tools and objects that may have been left inside the equipment. ? Use caution while removing or installing panels so that they do not extend into the energized bus; avoid handling the panels, which could cause personal injury.? The successful operation of this equipment depends upon proper handling, installation, and operation. Neglecting fundamental installation requirements may lead to personal injury as well as damage to electrical equipment or other property.? NEVER bypass external fusing.? NEVER short the secondary of a PT.? NEVER open circuit a CT; use the shorting block to short circuit the leads of the CT before removing the connection from the power meter.? Before performing Dielectric (Hi-Pot) or Megger testing on any equipment in which the power meter is installed, disconnect all input and output wires to the power meter. High voltage testing may damage electronic components contained in the power meter.?The power meter should be installed in a suitable electrical enclosure.

Failure to follow these instructions will result in death or serious injury

It is much easier to set up the power meter before you mount the power meter into the panel.This section explains, how to set up the power meter before mounting the power meter in the panel.

1. Connect the auxiliary supply (control power) 80 to 270 VAC to terminals 11 and 12. Press and hold for two seconds, while powering up the power meter. The display enters PROG menu setup and displays SET. Refer to “Edit set parameters” for more information. Program the following readings for accurate readings: A.PRI, A.SEC: Set these values to match your CT primary and secondary values. For example, if your CT ratio is 200:5, set A.PRI =200.0 and A.SEC = 5.000. V.PRI, V.SEC: Set these values to your input voltage VLL of circuit, if your input voltage is < 500 VACLL. For example, if the input voltage is 300 VACLL, set V.PRI = 300.0 and V.SEC = 300.0. Use potential transformer (PT/VT), if the input voltage > 500 VACLL. Set the V.pri and V.sec values to match the primary and secondary of the PT(VT) respectively. For example, if PT(VT) ratio is 11 kV: 110, set V.pri = 11.00 k and V.sec = 110.0. Select one of the following system configuration according to your wiring configuration. SYS = STAR for 4-phase 3-wire system SYS = dLtA for 3-phase 3-wire system.2. Connect the current transformers (CTs).

3. Connect the voltage inputs. Use PT(VT) if input voltage exceeds 500 VLL

Keypad SetupKeys Operation

PROG Menu - Setup

The following example explains, how the different keys in the power meter operates. The example explains, how to navigate from the RMS page to VLN page and back to RMS page, in ELF3259 meter.

1. Press from RMS page. The display shows VLL. 2. Press . The display shows VLN. 3. Press to go back to RMS page.

NOTE: Use to go forward to sub-parameter pages and to go back to main parameter pages. Use to scrollthrough the display pages in same level.

NOTE: The following symbols are used to explain the different operations of the keys. for right key operation. for left key operation. for down key operation.

The PROG menu setup gives the complete list of user-programmable parameters.? You must set up the power meter to match the application settings before use. Otherwise, readings will be wrong.? All the setup parameters can be re-programmed, using SET. However, the following settings critically determine the scaling of the measured readings: SYS (star or delta), Vpri, Vsec, Apri, Asec.? The scaling may be used to minimize the errors in reading due to Instrument Transformer errors. However, wrong settings will introduce errors in readings on other running systems.

You can enter PROG menu setup in ? View mode: To view the set parameters.

? Edit mode: To view or edit the set parameters.

Labeling of INTG Parameters

View INTG Parameters

? Your ELF3200 series power meter is equipped with an energy integrator function which provides several parameters for energy management: VAh, Wh, VARh (Ind), -VARh (Cap). ? The integrator parameters are always accumulated irrespective of the parameter selected in the setup. For example, if the parameter W is selected in the setup (PAR), all the energy parameters VAh, VARh, will be accumulated, along with the Wh in the integrator.? All the values stored in INTG are direct readings and have high resolution.

? The ELF3200 series power meter displays integrator values up to four digits both before and after the decimal point. ? The power meter has the following labeling for integrator parameters. If W is selected in the setup: ? W.H = First four digits of the energy value.

? W.h = Last/next four digits of the energy value.

? For example, if W.H = 01.00 and W.h = 0987, then the energy value is 1.000987.

1. Press from RMS page. The display shows INTG. 2. Press . The display shows W.H for one second and then the energy value’s first four digits 01.00.3. Press . The display shows W.h for one second and then the energy value’s last/next four digits 0987.

Table 8: Indicators

? Auto-scroll feature enables you, to view a group of display pages sequentially every five seconds without any manual key operation.? During auto-scroll, the power meter displays parameter name for one second and the value for four seconds.The following table explains the auto-scroll feature.

NOTE: The following example explains the auto-scroll through the RMS sub-parameter pages of ELF3259 meter.

Step Perform Output

1. Press , from the RMS page. The display shows VLL (RMS sub-parameter page of ELF3259).

2. Press continuously for three seconds The display flashes AUTO and starts and then release. auto-scroll down the sub-parameter pages.

Table 7: Auto-scroll

NOTE:Press any key to revert to manual scrolling. Auto-scroll feature is not possible in the setup parameters.

Kilo: When lit, indicates that the reading is in Kilo (10^3). For example, 32.00 with K LED lit indicates that the value is 32,000.Mega: When lit, indicates that the reading is in Mega (10^6). For example, 32.00 with M LED lit indicates that the value is 32,000 K.

GIGA: When both Kilo and Mega are lit, indicates that the reading is in Giga (10^9). For example, 32.00 with K, M LEDs lit indicates that the value is 32,000 M.

Negative: When lit indicates that the value is negative as per IEEE 100 and any industry standard.For forward flow of Watts and capacitive (leading) load, the VAR,PF values will be negative. For reverse flow of Watts and Inductive (lagging) load, the W, PF, and VAR values will be negative.

? When the integrator is cleared (manually or due to overflow), the energy values stored in the integrator will be transferred to the OLD register.? Thus the old energy values are not lost, even after the integrator is cleared, and can be viewed with the OLD parameter.

NOTE: For energy studies clear the integrator at the end of each observation. This transfers all the stored energy values to the OLD register, where they are held, while the integrator begins accumulating data for the next observation. Remember that the next time when the integrator is cleared, the OLD values will be overwritten.

INTG Overflow

? The energy values stored in the integrator are based on the PT ratio x CT ratio set for the application.? All the integrator values VAH/VAh, WH/Wh, VARH/VARh, -VARH/VARh reset together whenever any one of the values overflow. This enables easy energy management calculations.? The maximum number, the power meter can handle is 9999 giga for RMS and energy values.? During INTG overflow, the values stored in the integrator are transferred to OLD register.
