Page 3-1

3.1 INTRODUCTION

The IQ 300 is designed to be installed, operated and maintained by adequately trained personnel. These instructions do not cover all details, variations or combinations of the equipment, its storage, delivery, installation, checkout, safe operation or maintenance. Care must be exercised to comply with local, state and national regulations, as well as with industry standard safety practices for this class of equipment. Refer to figure 3.5 through 3.14 for wiring details.

WARNING

A THREE PHASE SWITCH OR CIRCUIT BREAKER SHOULD BE IN

CLOSE PROXIMITY TO THE IQ 300 MOUNTING LOCATION AND

MARKED AS THE DISCONNECTING DEVICE FOR THE EQUIPMENT.

ADDITIONALLY, IT IS RECOMMENDED THAT CT SHORTING TERMINAL

BLOCKS BE USED IN ORDER TO FACILITATE ANY FUTURE

MAINTENANCE OR REMOVAL OF THE IQ 300 BASE MODULE.

WARNING

TURN OFF AND LOCK OUT POWER SUPPLYING THE PANEL BOARD

OR SWITCH GEAR IN WHICH THE IQ 300 IS BEING INSTALLED.

FAILURE TO DO SO MAY CAUSE INJURY TO PERSONNEL OR DAMAGE

TO EQUIPMENT.

3.2 PANEL PREPARATION

It is recommended that the IQ 300 be mounted in an electrical switch gear enclosure that is suitable for its environment. The IQ 300 Display and IQ 300 Base

Modules may be mounted together or separately. The IQ 300 is designed with flexibility in mind. While it is recommended that the IQ 300 Display Module be dooror panel-mounted, the Base Module may be attached to the IQ 300 Display Module; mounted remotely using the supplied L-bracket; directly to a panel or floor; or attached to a DIN rail using the supplied DIN clip. For floor or panel mounting, a #10

(10-32) or #12 (12-28) screw is recommended.

In all instances where the IQ 300 Base Module is mounted remotely, the IQ 300

Display Module Chassis must be connected to earth ground.

Before installing the IQ 300, refer to dimensions listed in table 2.5 and allow adequate room for wiring and access to the IQ 300 Base Module terminals and



IL17574C

Page 3-2 connectors.

IQ 300


3.2.1 Mounting the IQ 300 Modules as a Single Unit

Since the IQ 300 is typically mounted on an enclosure door, it is necessary to prepare a cutout in which it will be placed. The dimensions for this cutout along with mounting hole locations are shown in figure 3.1. Note that the IQ 300 actually has ten mounting holes. Normally the top, bottom and center holes are used for a standard installation. If the installation is to be in a NEMA 3R or 12 inclosure, additional mounting holes are provided so that uniform pressure can be maintained on the gasket all the way around the unit.

Figure 3.1 Mounting Holes for the IQ 300 Display Module



IQ 300


IL17574C

Page 3-3

Before actually cutting the panel, be sure that the required 3-dimensional clearances for the IQ 300 chassis allow mounting in the desired location. IQ 300 dimensions without and with a base unit are shown in figures 3.2 and 3.3 respectively.

It is necessary to hold the tolerances shown when making the cutouts and placing the holes for the mounting screws. In particular, the horizontal dimensions between the center of the mounting holes are the vertical edge of the cutout must be within 0 and +0.050 in.

PowerNet Communications (IQ 320 and IQ 330 Base Modules

Only)

Note: To satisfy proper Wiring Specifications use only Belden 9463 or 3072F, or

Culter-Hammer IMPCABLE shielded twisted pair cable or equivalent, according to system requirements. SEE TD17513, IMPACC WIRING SPECIFICATIONS BASE

RULES for more detailed information.

Connect the IQ 320 / IQ 330 to the PowerNet network by connecting the twisted pair communication cable to the INCOM™ port located on the rear face of the

IQ 320 / IQ 330 Base Module. The polarity of the twisted pair is not important.

Tie the communication cable shield to ground only once at the INCOM™ master device. If there is more than one remote INCOM™ compatible devices (such as the

IQ 320 or IQ 330) cabled to the master device, tie the communication cable shields together but do not connect to ground.

Care must be taken in stripping wire due to close proximity of terminals.

3.3.4

KYZ Pulse Initiator (IQ 320 and IQ 330 Base Modules Only)

The KYZ Pulse Initiator output can be wired to a 2-wire (K-Y terminals) or 3 wire

(KYZ terminals) pulse receiver. In order to achieve emissions and immunity standards, shield cable should be used. The cable should be grounded on the non-IQ

Base end. These terminal configurations and the resulting pulse trains are shown in figures 3.15 and 3.16. The energy represented by each pulse can be specified by the user as: apparent (VAh); forward or reverse real (±Wh); or reactive (±varh).

The procedure for specifying the energy per pulse is described in section 4.10.9.

Each pulse that arrives at the pulse counter indicates that the specified energy has been consumed by the monitored system. The frequency and spacing of these pulses represent the energy consumption pattern of the monitored system.

Because the energy represented corresponds to the energy at the secondary winding of the CTs and PTs, the CT and PT ratios must be taken into account when specifying the energy per pulse value. An example of how to specify the energy per

pulse value is given below.



IL17574C

Page 3-14

Example:

System Configuration

CT = 1400:5

PT = 2:1

IQ 300


Desired value to monitor watthours

System parameters

Assume the IQ 320 is monitoring a constant system power of

16,800 Watts.

Step 1: Calculate the CT and PT ratios

CT ratio = 1400/5 = 280

PT ratio = 2/1=2

Step 2: Calculate the power at the secondary of the CTs and PTs power at secondaries = 16,800 Watts / (CT ratio x PT ratio) power at secondaries = 16,800 Watts / (280 x 2) power at secondaries = 16,800 Watts / 560 power at secondaries = 30 Watts (or 30 watthours in 1 hour)

Step 3: Specify the energy per pulse as desired

Specify secondary energy per pulse = 1 watthour per pulse; then, each pulse represents system energy of:

(1400/5) x (2/1) x 1; or 560 watthours per pulse

or

Specify secondary energy per pulse = 7 watthours per pulse; then, each pulse represents system energy of:

(1400/5) x (2/1) x 7; or 3,920 watthours per pulse

Inputs and Outputs (IQ 330 and IQ 330M only)

The IQ 330 offers additional inputs and outputs. In order to achieve the emissions and immunity standards, shielded cable should be used. The cable should be grounded on the non-IQ Base side of the cable. These inputs and outputs include the Digital Inputs labeled IN1 and IN2, the Analog Input labeled AN1 and the two

Outputs labeled A1 and A2.

Digital inputs and long Modbus responses compete for the same processor bandwidth. In order to ensure accurate input readings, limit block requests in

Modbus to 3 variables (6 Modbus registers) when reading digital inputs with pulse width of 200 ms between 5 and 10 Hz. Limit block requests in Modbus to 6 variables (12 Modbus registers) when reading digital inputs with pulse width of 200 ms.

SECTION 4: OPERATION

4.1

GENERAL

The IQ 300 Display Module provides both local display of system values and a method of assigning an INCOM address to the IQ 320 and IQ 330, and a separate

MODBUS address to the IQ 330 to enable communications.

The IQ 300 Display Module allows the user to view information and to specify or change the functions of the IQ 300 system. These items include system and phase data, min/max data, set points and screen contrast.

It also provides a method of assigning a network address and communication baud rate to the IQ 320 and IQ 330 Base variation, should it be networked to a PowerNet master device.

All functions of the IQ 300 are available through menus visible on the screen of the

IQ 300 Display Module Operator Panel. Choice of menu and selection of menu options is accomplished by pressing the buttons on the face of the Operator Panel.

Figure 4.0 IQ 300 Screen

The screen of the IQ 300 is divided into four sections. The numeric top row that allows you to read the numerical value of what you have chosen. The alphanumeric digits on the bottom row describes the value. The center row of words tells you which menu and which branch of menu you are in. These words can be used alone or in combination with each other. For example if the maximum phase A current is being displayed both the Phase and Max words will be displayed. The lower right corner of the display has 3 icons. The arrow is on when up is a valid path and

DISPLAYED SIGN CONVENTIONS

The IQ 300 not only displays system

Display Indication

Lg

lagging (inductive) values, but also indicates whether factors are lagging or leading by displaying Lg or

Ld

leading (capacitive)

Ld, see table to the left.

The IQ 300 is shipped with lagging vars and power factor represented by negative values at the load, conforming to the

mathematical sign convention. The IQ 320 and IQ 330 allows the user the ability to change to the power engineer convention, which assumes positive values at the load. The convention can be changed in the IQ 320 and IQ 330 via the INCOM communications interface. The IQ 320 and the IQ 330 must be connected to a

PowerNet network and programmed accordingly. Only the mathematical convention is available when using the IQ 310 Base.

The following relationships apply:

USING THE OPERATOR PANEL

When the IQ 300 is first powered on, the Operator Panel screen displays a brief initialization message identifying the product and version. The screen then displays the System Power screen. (At this point, pressing the Scroll arrows will display system data as described in section 4.6 System Data Display Mode.)

Press the Menu button to proceed. The menu options are shown one at a time, starting with Phase Data, see figure 4.2. Press the scroll up or down arrows to step through all the main menu options. The presence of additional items is indicated by the up and down triangles at the bottom right edge of the screen.

Keep in mind that the values displayed under several menu items depend on which unit you are using and whether the system being monitored is 3 or 4 wire, and require that the appropriate configuration be selected under the Edit Setpoints menu. Menu descriptions cover both 3 and 4 wire systems where appropriate.

Note: The lagging or leading indicator and any signs may be the opposite of that shown in the sample screens.

3 Wire System and 4 Wire System

The System Data screens, shown in figure 4.3, are the same for 3 and 4 wire systems. Only when you are using the IQ 330 or IQ 330M will you see the digital input counters and lock status display screens.

4.6.3

System Input (IQ 330 and IQ 330M only)

The System Input displays the accumulated counts of the two digital inputs and the value of the 4 to 20ma analog input. The digital inputs count the positive and negative edges of a square wave signal. The signal must have an amplitude greater than 12 volts and will be clamped at 50 volts. The counts will roll-over the display at

65535. The counts can be tracked to 4294967295 via INCOM and the MODBUS pass through commands before roll over occurs.

The 4 to 20ma analog input will be represented as 0 to 100 percent on the display.

4.6.4

System Lock (IQ 330 and IQ 330M only)

The lockout feature is unique to the IQ 330 type models. The feature is a physical shaft or button protruding from the top of the base. The shaft has a hole in it so the wire tamper proof seal can be employed to disable it. The feature is a toggle. Press the button and the unit will be locked. Press the button again and the unit will be unlocked.

While in the locked state changes to setup and reset values (listed below) will be denied. When a user tries to change any of the values in the list below an ERROR

TRY AGAIN message will appear. Simple unlock the IQ 330 to access these functions.

In PHASE mode the output will be in closed state when the three phase voltages are in phase and the open state when the three phase voltages are out of phase.

When in Voltage mode the output will be closed when the voltage strays from the

100% nominal reading. The nominal readings will be 120,

240, 480 and 575. The programmable trip value will determine when the output will be closed. If the rms voltage drops below a percentage less than 100% the relay will be closed. If the rms voltage goes above a

XX percentage that is above 100% the relay will be closed. In both cases the relay will stay closed until open by a

TRIP VALUE message. For example if the nominal voltage is 480 V and you want the unit to trip if the voltage drops below 420 V, multiply 420 by 100 and divide it by 480 to find your setting.

SECTION 5: NETWORK COMMUNICATION PROTOCOLS

5.1

MODBUS RS485 NETWORK

The IQ 330M can be accessed by MODBUS messages through a RS485 interface.

In order to do this properly please refer to IL 17384, Part A and Part B: IMPACC

Communications Standard, EATON | Cutler-Hammer “Modicon MODBUS Protocol” and IL 66A7508H01 Instructions for the mMINT MODBUS Translator Module.

The following simplified rules apply to a given system consisting of master and slave devices. For more complex configurations please refer to standard MODBUS RTU wiring specification rules for the RS485 network.

The recommended MODBUS cable has twisted-pair wires (24AWG stranded 7x32 conductors with PVC insulation) having an aluminum/mylar foil shield with drain wire.

The maximum system capacity is 4,000 feet of communications cable and 32 devices on the MODBUS RTU network.

Make sure the twisted-pair wire is recommended for MODBUS RTU network use.

Use shielded twisted-pair wire to connect each slave to the MODBUS RTU network, daisy-chain style. The polarity of the twisted pair is critically important, MODPIN1 is

MOD(A) and MODPIN2 is MOD(B).

Tie the communication cable shield to ground only once at the MODBUS master device. If there are more than one remote MODBUS compatible device cabled to the master device, tie the communication cable shields together but do not connect to ground.

5.2

OVERVIEW

The contents of MODBUS registers are product objects (e.g. Ia – phase A current).

There is a single register map for all Eaton | Cutler-Hammer IQ products. Consequently, the objects listed in the following tables are identical registers called out by the mMINT. The IQ 330M supports the fixed values only and occupy two registers.

See table 5.1.

The register data in the response message are packed as two bytes per register.

For each register, the first byte contains the high-order bits and the second contains the low-order bits.

Because all of the data in the IQ 330M is stored as a 32 bit signed integer, you always want to retrieve two registers to get the result. See below for an example.

One item is made up of 4 bytes of information. Using table 5.1 locate the MODBUS address of 1804, this is the numeric object or item for I

EXTENDED COMMUNICATIONS VIA MODBUS

Since a control error could result in unwanted actions initiated by MODBUS the IQ

300 requires a specific protocol by the MODBUS Master in order to perform control related functions within the IQ 300

A set of registers is reserved for the control protocol. They begin at register 6200 hex and extend through 6203 hex. These three registers are written with a ‘slave action number’ and it’s 1’s complement, using function code 10 hex. The format of the data is shown in figure 5.2. These three registers, and only these three registers, must be written in one MODBUS transaction.

If the ‘slave action number’ is valid and not blocked by a LOCKED system , the IQ

300 issues the ‘slave action’ control command.

COMMAND DATA PASS THROUGH

A feature of the IQ 330 is its capability to pass INCOM commands/data directly via the MODBUS command. Thus, with access to IL 17384 Parts A and B, every

INCOM product object and capability is available to the MODBUS master.

When the pass through command is issued the unit saves the INCOM response in a holding register until the MODBUS Master queries for the last response. The Unit makes no modification to or interpretation of the product response data.

The MODBUS master writes the product command data using function code 10 hex beginning at register 6000 hex.

The data format for pass through data is given in Figure 5.3

The MODBUS master reads the INCOM product response to a pass through query using either function 04 beginning at register 6100 hex.

The number of points (registers) of the read query is 2*nn – where nn is the number of INCOM messages in the response.

The format of the data acquired by the IQ 330M from the pass through INCOM product query’s response is given in Figure 5.4 . Note that each INCOM response message contains a status byte which indicates its validity.

The INCOM Pass Through capability is a powerful tool, it allows you to retrieve any data that you could have retrieved with INCOM while using the

MODBUS protocol. The

Pass Through method requires the use of the sixteen command to start the INCOM request, followed by the four commands to read the response beginning at register 6100. Table 5.7 is an example of the INCOM 305 command.

Table 5.8 Example Response

The normal response returns a slave address, function code, starting address and quantity of registers preset. Table 5.8 is an example of the response to the query shown above.

Now you must retrieve the information starting at register

6100. First you need to know how many resisters to retrieve.

Second, be able to decipher the

INCOM floating point format that they will be in, along with the details individually related to each command. Table 5.9 is an example.

Refer to IL 17384 Part B related to

IQ 330 for additional information.

The only Pass Through command that does not require a read of register 6100 is the Download of Setpoints command (3F9). It is the only command that sends data to the IQ 330. See Table 5.11 for a description of this command.

From slave address to and including Message 1 Byte 0 the data is specific. In

Message 2 Byte 0 and 02 hex represents a CT ratio of 15:5 as shown in table 5.11.

A 00 hex in message 2 byte 1 shows a PT ratio of 1:1. An 0A hex in Message 2

Byte 2 shows a Dmd Window of 5 minutes, 3 wire, 60 hertz, with +VARs for lagging power factor. A 01 hex in Message 3 Byte 0 shows no KYZ selection. A 0A hex in

Message 4 Byte 0 shows Output 1 in message mode and Output 2 in phase mode.

A 02 hex in Message 4 Byte 2 shows a voltage trip value of 2%.
