THIS INSTRUCTION IS NOT A COMPLETE SOURCE

OF INFORMATION ON THE TRANSFER EQUIP-

MENT. INSTALLATION SHOULD NOT BE STARTED

UNTIL THE ENTIRE INSTRUCTION BOOK HAS

BEEN REVIEWED AND UNDERSTOOD. FAILURE TO

FOLLOW INSTRUCTIONS CAN RESULT IN DEATH,

SEVERE PERSONAL INJURY, OR PROPERTY

DAMAGE.

Step 1: Mount the transfer switch on a flat rigid surface

(Figure 1). Shim if necessary. For seismic mounting

requirements, check the instruction book.

Step 2: Install power cables. Cables shall be sized and

installed per National Electrical Code, refer to NFPA70.

The cable must be sized within the specified cable size

range on the side of the cable connectors.

Connect cables and torque to correct value indicated on

the label near the lugs in the following order: [1] Load

Cables* (T1, T2, T3), [2] Normal or Utility Supply (N1,

N2, N3), [3] Emergency and Generator Supply (E1, E2,

E3). For 4 pole transfer switches, connect load cables

(T4), normal or utility supply (N4), and emergency or

generator supply (E4). Refer to Figure 2 for the location

of all parts discussed in this document.

Load cables on switches using the vertical design MUST be

connected and torqued BEFORE installing the SUPPLY

cables (Figures 3 and 4).

Step 3: Turn generator OFF at the Generator Control

Panel. This will prevent unexpected activation of the

generator.

Step 4: Connect Engine Generator Control to

Terminals 51, and 52 (Red) (Figure 5). This contact is

CLOSED whenever the engine generator is needed,

and should be connected to a generator controller.

NEVER connect directly to a starter solenoid or ignition

system.

Step 5: Apply Utility (Normal) Power. If the switch is

properly applied for the system voltage ordered, the dis-

play should work and the

Normal Source (Source 1)

Available

LED should light (Figure 6). Using a voltmeter,

check for proper system voltage on the normal and load

terminals. Check all phases on a three-phase switch.

Voltage measurements should be taken phase to phase

and phase to neutral.

Step 7: To change or add a setpoint, place the <Run -

Program> switch on the rear of the IQ Transfer Logic

unit in the

Program

position (Figure 7). The red LED

next to

Program

on the front display will flash (Figure 6).

Figure 7 IQ Transfer Logic (Rear View)

Press the <Display Select> pushbutton until the Set

Points LED lights. Use the <Step> pushbutton to step

through the setpoints.

Use the <Increase> and <Decrease> pushbuttons to

change the setpoint.

When finished changing setpoints, return the <Run-

Program> switch to the

Run

position and wait. The dis-

play should display the word

Program

and the red LED

next to

Program

will go out. When the display goes

blank, the setpoints have been changed to their new

values.

Step 8: Manually start the engine generator at the gen-

erator controller (Figure 8). With the generator running,

check that the

Emergency Source (Source 2) Available

LED is lit. Press the <Display Select> pushbutton to

display the voltage and frequency on Source 2. Then

using the <Step> pushbutton, step through the phase

voltages, frequency and message display. If the source

message indicates that the source is

Good,

shut down

the generator and place the genset controller in the

Auto

operating position. If the message indicates a

problem with the source, the setpoints should be

reviewed, and the generator checked for proper voltage

and frequency output.

Step 9: Initiate a

Load Test

from the front panel of the

IQ Transfer (Figure 9). This may be done by making the

TMODE setpoint

and pressing the <Engine Test>

pushbutton. The generator should start, the ATS should

transfer and run on the generator for the set test inter-

val, then proceed to a TDEN countdown and return to

NORMAL. While the tansfer switch is connected to

emergency, use a voltmeter to check for correct system

voltage on the load terminals of the transfer switch.

Check all phases on a three-phase system. Voltage

measurements should be taken phase to phase and

phase to neutral. A

load test

will cause a momentary

power outage during transfer.

Step 10: ATHI/ATVI Power Failure Test - Initiate a Load

Test by simulating an actual power failure.

(1) This should be done by opening the upstream

breaker or fused disconnect switch.

(2) If the ATS is Service Equipment Rated with no

upstream disconnect, use the Normal Control Circuit

Disconnect to simulate a power failure (Figure 10).

This can be found in one of two places. The first

would be located directly beside the normal breaker.

The second would be located on the transformer

panel/customer connection panel. The normal con-

trol circuit disconnect is the disconnect marked

Normal.

The disconnect switch should be in the

position for normal operation. Turning the switch to

the OFF position will simulate a normal power out-

age.

Figure 10 Control Disconnect

(3) The generator should start and the ATS should

transfer to Emergency.

(4) After transfer, close the upstream breaker, or

close the Normal Control Circuit Disconnect. The

TDEN timer should begin counting, and, when com-

plete, the ATS should transfer to Normal. The En-

gine Cooldown Timer should time out and shut the

emergency power unit down.

NOTICE

While performing testing, if an undesired or undoc-

umented result occurs, first contact the local

Genset dealer. If the result is not corrected, contact

the Cutler-Hammer Product Integrity Center at

1-800-354-2070.
