DANGER is used in this manual to warn of a hazard situation which, if not avoided, will result in death or serious injury.

WARNING is used in this manual to warn of a hazardous situation which, if not avoided, could result death or serious injury.

CAUTION is used in this manual to warn of a hazardous situation which, if not avoided, could result in minor or moderate injury.

Rating Label Each transfer switch contains a rating label to define the loads and fault circuit withstand/closing ratings. Refer to the label on the transfer switch for specific values.

Do not exceed the values on the rating label.

Exceeding the rating can cause person injury or serious equipment damage.

An experienced licensed electrician must install the transfer switch.

Installation These transfer switches are factory wired and tested.

Installation requires mounting, connecting service cables, and connecting engine start and auxiliary control circuits (if required.).

Supporting Foundation The supporting foundation for the enclosure must be level and straight. Refer to the applicable enclosure outline drawing included with the transfer switch for all mounting details including door opening space.

If bottom cable entry is used, the foundation must be prepared so that the conduit stubs are located correctly. Refer to the enclosure outline drawing for specified area and location.

Provide cable bending space and 1 inch minimum clearance to live metal parts. When a concrete floor is poured, use interlocking conduit spacer caps or a wood or metal template to maintain proper conduit alignment.

Mounting Refer to the outline and mounting diagram and mount the transfer switch according to details and instructions shown on the diagram. Mount it vertically to a rigid supporting structure. Level all mounting points by using flat washers behind the holes to avoid distortion of the transfer switch.

Protect the transfer switch from construction grit and metal chips to prevent malfunction or shortened life of the transfer switch.

Line Connections Refer to the wiring diagram provided with the transfer switch.

All wiring must be made in accordance with the National Electrical Code and local codes.

De-energize the conductors before making any line or auxiliary circuit connections. Be sure that the Normal and Emergency line connections are in proper phase rotation. Place the engine generator starting control in the OFF position. Make sure engine generator is not in operation.

Testing Power Conductors Do not connect the power conductors to the transfer switch until they are tested. Installing power cables in conduit, cable troughs, and ceiling-suspended hangers often requires considerable force. The pulling of cables can damage insulation and stretch or break the conductor�s strands. For this reason, after the cables are pulled into position, and before they are connected, they should be tested to verify that they are not defective or have been damaged during installation.

Connecting Power Cables After the power cables have been tested, connect them to the appropriate terminal lugs on the transfer switch as shown on the wiring diagram provided with the transfer switch. Make sure that the lugs provided are suitable for use with the cables being installed. Standard terminal lugs are solderless screw type and will accept the wire sizes listed on the drawings provided with the transfer switch. Be careful when stripping insulation from the cables, avoid nicking or ringing the conductor. Remove surface oxides from cables by cleaning with a wire brush. When aluminum cable is used, apply joint compound to conductors. Tighten cable lugs to the torque specified on rating label.

Harnesses The transfer switch is connected to the left side of the controller by a plug-in harness (two plugs).

Auxiliary Circuits Connect auxiliary circuit wires to appropriate terminals on the transfer switch as shown on the wiring diagram.

Controller Ground A grounding wire must be connected to the controller�s lower left mounting stud. Because the controller is mounted on the enclosure door, a conductive strap must be used between the enclosure and the door. This connection provides proper grounding which does not rely upon the door hinges.

Engine Starting Contacts The engine control contact connections (if used) are located on the transfer switch for 3ATS & 3NTS or in the upper right side of the enclosure for 3ADTS & 3NDTS. Connect signal wires to appropriate terminals as specified in Table A and shown in Figure 1.

Functional Test The functional test consists of three checks: manual operation, voltage checks, and electrical operation.

Do these checks in the order presented to avoid damaging the transfer switch.

1 � Manual Operation A maintenance handle is provided on the transfer switch for maintenance purposes only. Manual operation of the transfer switch should be checked before it is energized (operated electrically).

Do not manually operate the transfer switch until both power sources are disconnected: open both circuit breakers.

1. After deenergizing both power sources, open the enclosure door. Locate and remove the maintenance handle from the clip on the left side of the transfer switch. See Figures 3, 4, and 5. See Figure 2 for the contact position indicators.

2. Install the handle into the hole in the molded hub. Move the handle up or down as shown to manually operate the transfer switch. It should operate smoothly without any binding. If it does not, check for shipping damage or construction debris.

3. 3ADTS and 3NTS have two contact shaft hubs. See Figure 5.

4. Return the transfer switch to the Normal position.

Note: If Normal and Emergency connections are reversed this operation is also reversed.

2 � Voltage Checks First check the nameplate on the transfer switch; rated voltage must be the same as normal and emergency line voltages.

Use extreme caution when using a meter to measure voltages in the following steps.

Do not touch power terminals; shock, burns, or death could result!

Perform steps 1 through 6 at the right. Observe the indicator lights. See Figure 6.

Black circle means the light is on.

White circle means the light is off.

* If necessary, adjust the voltage regulator on the generator according to the manufacturer�s recommendations. The transfer switch will respond only to the rated voltage specified on the transfer switch nameplate.

Also see User�s Guide 381333-400 for voltage settings in the controller.

Close the normal source circuit breaker. The normal source accepted and the load on normal lights should come on.

Use an accurate voltmeter to check phase to phase and phase to neutral voltages present at the transfer switch normal source terminals.

Close the emergency source circuit breaker.

(Start generator, if necessary.) The emergency source accepted light should come on.

Use an accurate voltmeter to check phase to phase and phase to neutral voltages present at the transfer switch emergency source terminals.*

Use a phase rotation meter to check phase rotation of emergency source; it must be the same at the normal source.

Shut down the engine-generator, if applicable.

The emergency source accepted light should go off. Then put the starting control selector switch (on the generator set) in the automatic position.

NOTE: For 3NTS manually start the emergency generator at the generator. Then press the transfer button for load transfer.

If the inphase transfer feature is activated, transfer may not occur immediately. Transfer will occur when the phase relationship between sources is correct. Press the transfer button again for load retransfer to normal, then manually stop the generator at the generator.

Also see User�s Guide 381333-400 for inphase transfer and time delay settings in the controller.

This completes the functional test of the transfer switch.

Leave the engine-generator starting control in the automatic position.

The normal source must be available and the generator must be ready to start. Check that the normal source accepted light is on.

For 3ATS & 3ADTS press the transfer button. The engine should start and run within 15 seconds. For 3NTS & 3NDTS the generator must be started manually at the generator.

The emergency source accepted light should come on.

For 3ATS & 3ADTS the transfer switch should transfer to the emergency position. The load on emergency light should come on and the load on normal light should go off. For 3NTS & 3NDTS press the transfer button for load transfer. For 3ADTS & 3NDTS both lights will be off during the delayed-transition transfer time delay.

If the transfer to emergency delay is used, the transfer occurs after a time delay. For immediate transfer (bypass timer) press the transfer button again.

For 3ATS & 3ADTS the transfer switch should transfer back to the normal position. The load on normal light should come on and the load on emergency light should go off. For 3NTS & 3NDTS press the transfer button for load retransfer. For 3ADTS & 3NDTS both lights will be off during the delayed-transition transfer time delay.

If the retransfer to normal delay is used the retransfer should occur after a time delay. For immediate retransfer (bypass timer) press the transfer button again.

For 3ATS & 3ADTS the unloaded running delay keeps the generator running for a cool-down period. Then the generator should stop and the emergency source accepted light should go off. For 3NTS & 3NDTS manually stop the generator at the generator (after a cool-down period).5

Overview 1-1

The Group G Controller handles the sensing, timing, and control functions for Automatic and Non-Automtatic Transfer Switches (3ATS, 3ADTS, 3NTS, 3NDTS). This microprocessor-based controller includes a user interface. All monitoring and control functions can be done with the enclosure door closed for convenience and safety. Voltage pickup and dropout settings and time delay settings can be made through a system of menus.

Control Overview

The user interface includes a graphic display, control buttons, and indicator lights. Five buttons allow access to all monitoring, control, and settings functions. Six lights show status indication of source acceptability, transfer switch position, and alerts. The screens are arranged in three levels. Access to some screens require entering a password (indicated by a closed padlock symbol).

Up-down arrows buttons The up and down arrow buttons are used to navigate the settings. These buttons also increase and decrease a value to modify a parameter while in the settings level screens.

Enter/save settings button (see page 2-1 for Are you sure? screen) The enter/save settings button moves from the status level to the Main Menu level and other levels. It also is used to select a parameter and to enter or save a new setting.

Escape button (see page 2-1 for Are you sure? screen) The escape button ignores a change and returns to the previous status level.

Transfer button (see page 2-1 for Are you sure? screen) The transfer button has several functions. Refer to the control message (bottom line) on the control status / home screen. A closed padlock symbol indicates that a password must be entered (see page 2-1).

Status Information

The controller provides the status of both power sources (normal and emergency) and the position of the transfer switch. Press the up and down arrow buttons. No password is required to navigate through these screens.

ATS Status Screen The ATS status is the home screen. It shows the present status of the ATS including: transfer sequence status, and running timers, status of connected source, and position of ATS. A control message appears below the status messages. The control message instructs the user on what action is available.

All other screens automatically return to the ATS Status screen (home screen) after five minutes of inactivity.

Metering Screen One of several metering screens is provided (a factory setting). It shows the rms voltage and frequency readings of the power sources. If the current sensing option is provided, the load current is also displayed.

Alarm Screen Active alarm message appear or no active alarms. A control message appears below the alarm message. If an active alarm must be acknowledged, the screen stays on until you press enter. Some alarms are self clearing.

Controller Screen Controller information, name, location, present date and time appears. If an optional software key (dongle) is plugged into the controller, a key symbol is shown in upper right corner of this screen. Accessory 11BE is described on page 5-1.

Source Acceptability (Feature 1C time delay is described on page 2-3.)

The controller considers a source unacceptable if any of these conditions are true:

• Any phase voltage of the source is less than the voltage dropout setting for more than the Feature 1C setting.

• Any phase voltage is greater than voltage trip setting for more than 3 seconds.

• Frequency of the source is less than the frequency dropout setting for more than Feature 1C setting.

• Frequency is greater than over-frequency trip setting for more than 3 seconds.

The controller considers a source acceptable again when all these conditions are true:

• Each phase voltage is greater than the voltage pickup setting.

• Each phase voltage is less than over-voltage trip setting by more than 2% of nominal.

• The frequency of the source is greater than the frequency pickup setting.

• Frequency is less than the over-frequency trip setting by more than 2% of nominal.
