1.2 PRODUCT OVERVIEW - The IQ-1000 operating setpoints, each referred to as a function. The setpoints associated with these functions are individually entered through the Operator Panel located of the IQ-1000

The functions consist of the following types of entries:

• Alarm Relay condition settings. An Alarm Relay closes when various conditions, such as motor cur- rents or temperatures, exceed the selected setpoints. The alarm serves as an early warning. The motor's operation is not affected.

• Trip Relay condition settings. A Trip Relay closes (or opens) when various conditions, such as motor current or temperature, exceed separately selected setpoints. Action of the Trip Relay is user-selectable.

FUNCTIONAL THEORY

3.0 GENERAL - This section describes how the IQ-

• Protective functions (Par. 3.2)

• Metering functions (Par. 3.3)

of motor has a specific damage curve. Usually it is called the 12T curve (current squared multiplied by time). motors, the current balance between phases is of major concern due to the additional heating associated with unbalanced phase condition. Current unbalance is mainly caused by voltage unbalance, the result of single- phase loads on a 3-phase system, and/or motor winding unbalance.

With larger horsepower motors, the design is usually rotor-limited. It therefore becomes important to determine the total heating effect motor can be considered to have two rotors (see Figure

FAILURE TO OBSERVE THIS PRACTICE CAN RESULT IN SERIOUS OR FATAL INJURY AND/OR EQUIPMENT DAMAGE.

5.3 WIRING GUIDELINES - The following guidelines

must be observed by the electrical crew when installing the 10-1000

11.

5.3.1 Wire Routing and Wire Types - When routing wires between the starter and the associated machine or process equipment, follow these guidelines:

Guideline 1 - Do not route the control or RTD wiring through the high-voltage compartment of the motor

tance of 1.5 ft. (45 cm) between the two types.

Guideline 3 - Any low-voltage control wiring routed out of the motor starter cabinet should be at least #14 AWG stranded copper wire.

Guideline 4

-When

connecting an 10-1000

II

to the Universal RTD Module using three-wire shielded cable, wire per connection guidelines RTD

Module IL 17367. The three-wire shielded cable

in

Table Ill of Universal

5.3.2 Wiring Connections - Make wiring connections according to the application-specific Wiring Plan Drawing for each installation. Certain wiring connections are

noted here for emphasis.

• Unused RTD inputs

on

the RTD Module should be wired together. For example, if MW5 and MW6 are unused, MW5 terminals 13, 14 and 15 should be wired to each other and MW6 terminals 17, 18 and 19 should be wired together.

• The interconnecting cable between the

RTD

Module and the RTD must have the cable's shield connected to the RTD Module

ONLY.

functions are discussed, the program menu item

7.1.3 Protection Curve - The motor protection curve

defines the motor-versus-time relationship that is gener- ated by the IQ-1000 I l's application software, hardware, and programmed set point values. Note Figure 7.2. Ide- ally, this curve is located as close as possible to the motor damage curve, thus allowing maximum utilization of the motor without damage.

in

(The motor damage curve is defined as that point

the

relationship between the motor current and time where

thermal damage results.) When the motor current-versus-time relationship exceeds

this damage curve, a trip condition occurs, and the motor

is turned off. The IQ-1000

11

automatically calculates the correct motor protection curve for a specific application after the follow- ing items are entered: full-load amperes rating (item 42); locked rotor current (item 17); maximum allowable stall

time (item 18); and ultimate trip (item 19).

A brief discussion of how these values affect the motor protection curve is given The typical curve shown factors listed

In

(item 42).

general, the instantaneous overcurrent set- point for all applications should be at least 1.6 times the locked rotor current ratio. The instantaneous overcurrent

setpoint available range is 300 thru 1600% of full-load amperes.

NOTE: For the 1.0.C. trip level to be effective, set it below your fuse interrupting rating or your contactor

withstand capacity.

NOTE: The instantaneous overcurrent start delay

function (item 16) has a fixed minimum 1 cycle delay to detect the condition.

The

available setpoint range

for additional start delay is actually 1 thru 20 cycles.

7.1.3.2 Locked-Rotor Function

curves shown

in

Figure 7.2 is based upon a locked-rotor

current set point (item 17) of

-The

6.1

times (610%} the full-

AC

family of

line

load amperes function's (item 42) set point and a variable locked-rotor stall time set point (item 18).

All curves shown

in

Figure 7.2 are based

on

a maximum

allowable stall time from a cold start. Since the IQ-1000

ll's algorithm retains a history of both the operating cur-

rent and operating time of the motor, it is not necessary to program it for hot starts. The unit automatically takes into consideration whether it is a hot or cold start. The locked-rotor set point, however, should be set for a cold start.

7.1.3.3 Ultimate

Trip-The

ultimate trip function's (item 19) set point is the lowest value of current above which the motor can be damaged over time.

If

the motor has a service factor larger than 100%, the ultimate trip level can be increased accordingly. A service factor of

1.25 could be used with a 125% ultimate trip level.

7.1.3.4 Underload

Functions-When

the motor is running, a sudden current reduction indicates a malfunc- tion

in

the driven equipment. If the current level falls below the user-set underload alarm value (item 26), alarm condition exists.

If

the current falls below the

an

underload trip level (item 27), a trip condition occurs and

the motor is taken off-line.

Underload protection is used problems such as a blocked flow pressure

The customer application engineer should take these fac-

ultimate trip set point level. Should the curve not be ade- quate to protect the motor due to stator limitations at ele- vated ambient temperatures, then the use of RTDs

recommended. RTDs allow full utilization of the power available from the motor, and they reduce unnecessary shutdowns.

Disabling the motor start transition (time) function (item

38) cancels any transition time, but these timers, if used, continue to operate independently of the duration of the start cycle. (See Paragraph 8.15 for details.)

7.2.2 Run Cycle - Once the transition occurs, the motor's run cycle is initiated and the message "RUN" displayed. The run cycle continues until the monitored motor current level falls below 5% of its full-load amperes setpoint (item 42) at which point a stop the IQ-1000 (See Figure 7.6.)

The run cycle is another normal motor operating state. Protection functions with run delays are active state once the start delay has expired. The primary func- tion of run delays are:

• Ground fault run delay timer. (Program menu item 13; described

• Jam run delay timer. (Program menu item 25; described

• Underload run delay timer. (Program menu item 29; described

• Phase unbalance alarm run delay timer. (Program menu item 31; described

Keep the start delay for that function has timed out. The actual

run

delay begins timing only after a transient trip condi-

tion occurs. (See Paragraph 8.1.)

7.2.3 Stop Cycle - When the monitored motor current

level falls below 5% of the full-load amperes setpoint (program menu item 42), the stop cycle begins. When the IQ-1000 mode, Ready mode, or any trip mode.

When the anti-backspin delay time function (item 41) is used, it is initiated along with the stop cycle. The anti- backspin function prevents a start cycle's initiation until the user-selected setpoint time elapses. (The and/or Auxiliary Trip Relay is used vent a motor start. See Paragraph 8.17 for more details.)

SECTION 8

PROGRAMMING THE IQ-1000

8.0 GENERAL - This section contains information

needed by an application engineer to organize the set-

point values for a specific IQ-1000 easily entered. Thirty-eight separate functions are pro- vided. (See Table 8.A which acts as a quick locator alphabetized listing.) It is strongly recommended that the setpoints be determined, recorded and verified

before any entry is begun. For assistance, a Set Point

Record Sheet is included to act as a permanent record of the set point values for an individual application (see Table 8.B). Copies of it should be made and stored in a number of locations, including the enclosure containing

A copy of a correctly filled-in Set Point Record Sheet must be given to the individual responsible for value entry. The lQ-1000 fixed sequence that is duplicated on the Set Point Record Sheet. Thus, the sheet minimizes programming time. (Specific entry procedures are described

All start delays are tied to the transition cycle respect ated by the IQ-1000 tions are the instantaneous overcurrent and ground fault functions which react Once a start is declared, start delays may time out before or after the IQ-1000 depending on the type of protection. If a trip condition during a start is maintained past the end of the start delay, a trip may occur, never allowing the IQ-1000 transition to the run mode.

8.1.2 Run Delays - Run delays are used to provide a

time-based filter on transient trip conditions which might cause nuisance tripping.

The run delay is initiated by a transient trip condition

occurring after the associated start delay has timed out. Once the run delay has begun, the trip condition must be maintained for the full length of the run delay. If at any

time the condition goes away and then returns, the run

delay is reset. The trip condition must remain present for the full length of the run delay time to initiate a trip.

The fastest response for a function with both start and run delays is found by adding the two programmed delays together. This would be the response time if the trip condition were detected at any point during the start delay.

8.15 MOTOR START

TRANSITION-The

in

Table 8.B.

IQ-1000

II provides a relay which can be set to energize on certain current levels

or

timing delays. User-programmmed set-

points are required for the transition current level (item

37), the transition time (item 38), and action to take on transition time out (item 39). This transition relay can be used to control:

• Soft-start type motor starts

• Low- and high-voltage reduced voltage motor

starters

• Any type of clutch between the motor and the driven

load. (The clutch will be engaged after the motor attains the desired speed.)

8.15.1 Setpoint Item 37, Motor Start Transition (Current

Level)-

The motor start transition (current level) function specifies the current level below which the IQ-1000 ll's transition relay will be energized. The current level is measured as a percent of full-load amperes.

The primary transition function is based on current. The transition time (item 38) is used as a backup

in

case the

motor stalls during starting. When 30% of full load is

detected

in

any phase by the IQ-1000

II,

a start

is declared. The normal inrush currents of a motor (even a solid-state starter with the voltage phased back) will exceed any of the allowable transition current levels

in

immediately. If the current

any phase falls below the transition level within the transition time, the transition relay is energized and will remain so until a stop or trip condition occurs (see Figure

8.1

).

Once a start has occurred, the current must go above the transition level within 8 line cycles or an immediate transition may be ini- tiated.

The motor start transition setpoint function

is

displayed

in

the program menu as:

TRNC

XXX

Here the letters xxx represent the user-selected current

level below which point the transition relay will be ener-

in

gized. This menu item is numbered 37

Table 8.B.

The range of available setpoint values is:

Current: 50-150% of the full-load amperes rating

(in 1 % increments)

If the transition relay is not used, the transition current

should be set to the maximum setting of 150%

** Disable setting for TRNT - 0 seconds **

If

the transition relay is not used (as

in

across the line starts), the transition current (item 37) should be set to a maximum (150%) and the transition time to O seconds to

force

an

immediate transition (see Figure

).

However,

if the transition current setpoint is set to a minimum to

relay can be used as a generic timer controlled by the

transition time. Care must be taken to insure the current will never fall below 50% (minimum transition current

level setpoint) before the transition time elapses.

8.17 SETPOINT ITEM 41, ANTI-BACKSPIN

DELAY-

The anti-backspin delay function prevents a motor restart for the duration of the user-specified time.Timing begins concurrently with a trip or stop condition. This function guards against any attempt to start the motor while it is

rotating

in

a reverse direction, as may be caused with certain types of loads. A typical example is the backspin of a pump and motor caused by the descent of a column

of water after pumping is terminated.

This item is numbered 52

For setpoint entry purposes, refer to the application's wir- ing plan drawings for the correct CT ratio. Use the follow- ing criteria to select a current transformer:

• For optimum metering accuracy at low loads, select a unit which, at 100% full-load amperes, delivers from

3.5 to 4 amperes at the secondary. A CT which deliv- ers 2.5 to 4 secondary amperes at 100% FLA is also adequate for reliable motor protection.

• Select the CT which supplies as close to 3.75 amperes as possible at 100% full-load amperes.

For example, assuming an application where the motor starter delivers 300 full-load amperes, a 400:5 primary-

to-secondary ratio will deliver:

This is within the recommended range of 3.5 to 4.0 amperes. The CT ratio for this example would be 400:5.
