1. Introduction

OPERATORS MANUAL

This manual covers models produced under theCummins Power Generation brand names.

This manual provides information necessary foroperation, installation, and service of an GTECtransfer switch. This manual also includes parts in-formation.

This is an open transition transfer switch that in-cludes an automatic transfer switch (ATS) control.With an open transition switch, there is never a timewhen both sources are supplying power to the load.

Programmed transition switches briefly pause inthe neutral position of the transfer switch, betweenswitched positions, so that transient voltages fromthe load can diminish before the load is switched tothe other source.

TRANSFER SWITCH APPLICATION

Transfer switches are an essential part of a build-ings standby or emergency power system. Theutility line (normal power), is backed up by a gener-ator set (emergency power). The transfer switchautomatically switches the electrical load from onesource to the other.

The load is connected to the common of the ATS(Figure 1-2). Under normal conditions, the load issupplied with power from the utility (as illustrated).If utility power is interrupted, the load is transferredto the generator set (genset). When utility power re-turns, the load is retransferred to the utility. Thetransfer and retransfer of the load are the two mostbasic functions of a transfer switch.

TRANSFER SWITCH FUNCTION

Automatic transfer switches, capable of automaticoperation without operator intervention, performthe basic function of transferring the load to theavailable power source. The controller monitorseach source for allowable voltage and frequencyrange.

This automatic transfer switch, capable of automat-ic operation without operator intervention, is de-signed for utility-to-genset applications. In utility-to-genset applications, the transfer switch performsthe following functions:

1. Senses the interruption of utility power.2. Sends a start signal to the genset.3. Transfers the load to the genset.4. Senses the return of utility power.5. Retransfers the load to the utility.6. Sends a stop signal to the genset.

INSTALLATION OVERVIEW

These installation recommendations apply to typi-cal installations. Whenever possible, these recom-mendations also cover factory designed options ormodifications. However, because of the many vari-ables in any installation, it is not possible to providespecific recommendations for every situation. Ifthere are any questions not answered by thismanual, contact your nearest Cummins/Onan dis-tributor for assistance.

Application and Installation

Installations must be carefully planned and correct-ly installed for proper operation. This involves twoessential elements: application and installation.

Application refers to the design of the completestandby power system that usually includes powerdistribution equipment, transfer switches, ventila-tion equipment, mounting pads, cooling systems,exhaust systems, and fuel systems. Each compo-nent must be correctly designed so the completesystem functions as intended. Application and de-sign is an engineering function generally done byspecifying engineers or other trained specialists.Specifying engineers are responsible for the de-sign of the complete standby system and for select-ing the materials and products required.

Installation refers to the actual set-up and assem-bly of the standby power system. The installers setup and connect the various components of the sys-tem as specified in the system design plan. Thecomplexity of the standby system normally re-quires the special skills of qualified electricians,plumbers, sheet metal workers, etc. to completethe various segments of the installation. This isnecessary so all components are assembled usingstandard methods and practices.

Safety Considerations

The transfer switch has been carefully designed toprovide safe and efficient service when properlyinstalled, maintained, and operated. However, theoverall safety and reliability of the complete systemdepends on many factors outside the control of themanufacturer. To avoid possible safety hazards,make all mechanical and electrical connections tothe transfer switch exactly as specified in thismanual. All systems external to the transfer switchmust comply with all applicable codes. Make cer-tain all required inspections and tests have beencompleted and all code requirements have beensatisfied before certifying the installation is com-plete and ready for service.

Verify that both power source voltages match thenameplate rating prior to installation.

CONTROL PANEL

Figure 3-5 shows the control panel on the cabinetdoor. Two types of controls are available with GTECtransfer switches.

TS1311 controls are used on transfer switcheswith line-to-neutral voltage sensing.

TS1310 controls are used on transfer switcheswith line-to-line voltage sensing.

The front of the control panel is the same for bothtypes of controls.

The control features are divided into three groups:

Control Function LEDs ATS Status LEDs Membrane Pushbuttons

Control Function LEDs

The control panel (see Figure 3-5) includes eightLEDs that display codes that indicate various con-trol functions that can be configured. The first fiveLEDs display the function code and the last threeLEDs display the value code for the displayed func-tion. For information on configuring these func-tions, see Section 5.

With the exception of the first LED (Test), normallythese LEDs are off and are only lit when in Configu-ration Mode. The Test LED is also used to notify theuser of test periods.

ATS Status LEDs

The control panel includes six LEDs that provideAutomatic Transfer Switch (ATS) status informa-tion.

Utility Power Available This green LED is litwhen the utility power source has acceptable out-put voltage.

Genset Power Available This amber LED is litwhen the genset power source has acceptable out-put voltage and frequency.

Both power source LEDs can be lit simultaneously.

Utility Power Connected This green LED is litwhen utility power is supplying power to the load.

This LED flashes once per second if there is a fail-ure to connect to or disconnect from utility power,

when commanded. The control makes five at-tempts (there is ten seconds between each at-tempt) to connect to or disconnect from utility pow-er before it flashes the failure.

Genset Power Connected This amber LED is litwhen the genset is supplying power to the load.

This LED flashes once per second if there is a fail-ure to connect to or disconnect from the genset,when commanded. The control makes five at-tempts (there is ten seconds between each at-tempt) to connect to or disconnect from the gensetbefore it flashes the failure.

Test This amber LED is lit when there is an activetest period. This LED flashes twice per secondwhen the Test pushbutton is pressed to set or can-cel a test period.

Exercise This amber LED lights when repeat ex-ercise periods have been set. This LED flashestwice per second when the Set Exercise pushbut-ton is pressed to set or cancel an exercise. ThisLED flashes once per second during an active ex-ercise period.

Membrane Pushbuttons

The control panel includes three membrane push-buttons.

Test The Test pushbutton is used to set or cancela test period. The control can be configured to testthe genset with or without load. For more informa-tion, see Section 4.

The Test pushbutton is also used in the Configura-tion Mode to step through the function codes (seeSection 5).

Override The Override pushbutton is used to ter-minate or bypass some time delays, to stop thePower Connected LEDs from flashing as a result ofa failure to connect to or disconnect from a powersource, and to cancel an active exercise period.For more information, see Section 4.

The Override pushbutton is also used in the Config-uration Mode to step through the value codes (seeSection 5).

Set Exercise The Set Exercise pushbutton isused to set or cancel repeat exercise periods usingthe integrated exerciser. For more information, seeIntegrated Exercises on page 4-8.

ELECTRONIC CONTROL SYSTEM

This section describes the standard and optionalcomponents of the electronic control system.

WARNING Improper calibration or adjustmentof electronic control modules can cause death,severe personal injury, and equipment or prop-erty damage. Calibration and adjustment ofthese components must be performed by tech-nically qualified personnel only.

Installation of these components and calibrationand adjustment procedures are described in Sec-tion 7.

WARNING AC power within the cabinet andthe rear side of the cabinet door presents ashock hazard that can cause severe personalinjury or death. When the cabinet door is open,use extreme caution to avoid touching electri-cal contacts with body, tools, jewelry, clothes,hair, etc.

Transfer Inhibit Input

A transfer inhibit input is set up by connecting a dry(voltage free) contact between TB1-6 and TB1-8.Closing the contact enables the feature and open-ing the contact disables it.

This feature is used to control load transfer to gen-sets. When enabled, load transfer will not takeplace unless the Override pushbutton on the con-trol panel is pressed or the transfer inhibit input isdisabled.

Pressing the Override pushbutton on the controlpanel bypasses the transfer inhibit input and by-passes TDNE. The TDNE runs if the transfer inhibitinput is disabled.

Retransfer Inhibit Input

A retransfer inhibit input is set up by connecting adry (voltage free) contact between TB1-7 andTB1-8. Closing the contact enables the feature andopening the contact disables it.

This feature is used to prevent the ATS from auto-matically transferring the load back to the utility.When enabled, load transfer will not take place un-less the Override pushbutton on the control panel ispressed, the retransfer inhibit input is disabled, orthe genset fails. If the genset fails, retransfer inhibitis ignored.

Pressing the Override pushbutton on the controlpanel bypasses the retransfer inhibit input and by-passes the TDEN. The TDNE runs if the retransferinhibit input is disabled.

Remote Test Input

The transfer switch may be wired for a remote testinput. The switch is used to start and stop manuallyinitiated system tests. As with the control panel Testpushbutton, the remote test input can be config-ured to test with or without load. More informationon testing is included in Section 4.

A remote test input is set up by connecting a dry(voltage free) contact between TB1-5 and TB1-8.Closing the contact starts a test and opening thecontact cancels the test. The Test LED flashes tosignify the start of a test and stays on during thetest.

Closing the contact causes the transfer switch tosense a (simulated) utility power failure and sendsa start/run signal to the genset. If the control is setup to test with load, the load is transferred to thegenset when the genset becomes available. TheUtility Power Available LED remains on to showthat the utility did not fail.

Two-Wire Starting

The starting circuit is a basic supervisory functionof the electronic control. Water-cooled generatorsets use a two-wire start control.

Although the logic is more involved, the two-wirestarting circuit can be thought of as a single pole,single throw switch. A closed switch starts the gen-erator set. An open switch stops the generator.

NOTE: Three-wire starting is not available onGTEC transfer switches.

TRANSFER SWITCH

The transfer switch (see Figures 3-1 thru 3-4)opens and closes the contacts that transfer theload between the power sources. The switch is me-chanically interlocked to prevent simultaneousclosing to both power sources. The main parts ofthe switch discussed here are the contact assem-blies, linear actuator, and auxiliary contacts.

Contact Assemblies

The automatic transfer switch has either two, three,or four poles. Three pole transfer switches are pro-vided with a neutral bar. The contact assembliesmake and break the current flow. When closed toeither power source the contacts are mechanicallyheld. A mechanical interlock prevents them fromclosing to both power sources at the same time.

Electro Mechanical Actuator

Actuator operation is initiated automatically by thetransfer switch control. Manual operation of theswitch is also possible. Refer to Manual Operationin Section 4.

3-9

Auxiliary Contacts

Auxiliary contacts are provided on the utility andgenset sides of the transfer switch (see Figure 3-9).They are actuated by operation of the transferswitch during transfer and retransfer. The utilityauxiliary contact switch is actuated when the trans-fer switch connected to the utility. The genset auxil-iary contact switch is actuated when the transferswitch is connected to the genset. The auxiliarycontacts have current ratings of 5 amperes at 250VAC. The contacts are wired to terminal block TB1.

FIGURE 3-11. EXTERNAL EXERCISE CLOCK

Programs are available to set exercise start andstop times. One program is required to start an ex-ercise period and a second one is required to stopan exercise period.

The exercise clock has a built-in test feature thatcan be used to initiate an exercise that hasnt beenprogrammed or cancel a programmed exercise inprocess.

Information on setting the clock is included in Sec-tion 4.

NOTE: The clock includes a non-replaceable lithi-um battery with a life expectancy of at leastten years. If the clock battery is weak duringa power failure, the clock will need to be re-placed.

Elevator Relay Option

Connections to the elevator relay are made directlyto the relay terminals. The elevator relay ismounted on the DIN rail. The terminals accept wiresizes from one number 18 AWG (1.0 mm2) wire totwo number 12 AWG (4.0 mm2) wires. For connec-tion to the screw terminal, strip the insulation back3/8 inch (10 mm).

There are two types of relay coils (12 VDC and 24VDC).

The relay has two sets of Form-C contacts that arerated for 5 amperes at 250 VAC (see Figure 3-12).

Manual Restore Option

The optional Manual Restore key switch (see Fig-ure 3-13) is located on the front panel below theControl Panel.

When the switch is set to Retransfer Inhibit, theload remains connected to Source 2 after a trans-fer. When the switch is set to Force Retransfer toUtility, the load is transferred back to Utility power.

A manual restore input is set up by connecting a dry(voltage free) contact between P4-2 on the back ofthe control panel and TB1-7 and TB1-8 (see Figure3-14). Closing the contact enables the feature andopening the contact disables it.

4. Operation

TIME DELAYS

The transfer switch control uses various time de-lays to break from one power source and reconnectto the other source. The control panel can be usedto adjust these time delays (see Section 5).

In the following descriptions of time delays, it is im-portant to remember that:

When the transfer switch is connected to Nor-mal, it is connected to the utility power source.

When the transfer switch is connected toEmergency, it is connected to the Genset pow-er source.

When the transfer switch is in the Neutral posi-tion, it is not connected to either power source.

Time Delay Engine Start (TDES)

This time delay prevents the generator from start-ing during brief utility power interruptions. This tim-er starts the instant the utility fails, as detected bythe Undervoltage Sensor.

When the control senses a utility failure, the controlstarts the Time Delay Engine Start (TDES) timer.This time delay is configurable for 0 (disabled), 0.5,1, 2, 3, 4, 6, or 10 seconds (default = 3 seconds).

If utility power returns while the TDES timer is ac-tive, the timer is reset. When the timer expires, thecontrol de-energizes the start relay, closing thestart contact signalling the generator to start. Thetimer is not reset until utility power returns. If theOverride pushbutton is pressed or the Override in-put is grounded while the TDES timer is active, theTDES timer immediately expires.

Time Delay Engine Cooldown (TDEC)

This time delay allows the generator to cool down(under no load conditions) before the control turnsit off.

The Time Delay Engine Cooldown (TDEC) startstiming when the load is retransferred to utility pow-er. This time delay is configurable for 0 (disabled),0.1, 5, 10, 15, 20, 25 or 30 minutes (default = 10minutes).

When the TDES expires, the stop signal is sent tothe generator and the timer is reset. Pressing the

Override pushbutton or grounding the Override in-put has no effect on this time delay.

Time Delay Normal to Emergency (TDNE)

This time delay allows the generator to stabilize be-fore the load is applied.

While connected to Normal, this time delay startsafter utility power fails and the generator becomesavailable (the amber Genset Power Available LEDis lit). This time delay also starts after the generatorbecomes available when a with load Test or Exer-cise period is activated.

The time delay is configurable for 0 (disabled), 1, 2,3, 5, 30, 120, or 300 seconds (default = 5 seconds).If the generator fails any time during a TDNE, thecontrol resets the timer and restarts it once the gen-erator is again available.

If the Override pushbutton is pressed or the Over-ride input is grounded while the TDNE timer is ac-tive, the TDNE timer immediately expires. TheTDNE timer will not begin if a Transfer Inhibit inputis active.

Time Delay Emergency to Normal (TDEN)

While connected to Emergency, this time delay al-lows utility power to stabilize before the retransfercommand is issued. This delay also allows the gen-erator to operate under load for a minimum amountof time before transferring back to utility power.

This time delay starts with the transfer switch con-nected to the generator and after the utility be-comes available following an outage (The greenUtility Power Available LED is lit). This time delayalso starts when an active Test or Exercise period isended. After the delay, the transfer switch can re-transfer the load to the utility power source.

The time delay is configurable for 0 (disabled), 0.1,5, 10, 15, 20, 25 or 30 minutes (default = 10 min-utes). If the utility fails any time during this timedelay, the control resets the timer and restarts itonce utility power becomes available. If the gener-ator fails at any time during this time delay, the timerexpires and the normal retransfer sequence takesplace.

If the Override pushbutton is pressed or the Over-ride input is grounded while the TDEN timer is ac-tive, the TDEN timer immediately expires. The

4-2

TDEN timer will not begin if a Retransfer Inhibit in-put is active.

Time Delay Programmed Transition(TDPT)

This feature causes the transfer switch to pause inthe Neutral position for an adjustable period of timewhenever there is a transfer from one source toanother. The intentional delay allows the residualvoltage of an inductive load to sufficiently decay be-fore connecting it to another power source. Thisdelay prevents potentially damaging voltage andcurrent transients in the customers power system.If TDPT is set to zero, then the transfer switchtransfers from one source to the other with no neu-tral position delay.

The control activates a Program Transition TimeDelay (TDPT) whenever the transfer switch hasdisconnected from one source and is in the Neutralposition. The time delay is configurable for 0 (dis-abled), 0.5, 1, 2, 3, 4, 6 or 10 seconds (default = 0seconds). The control also detects if the transferswitch has disconnected from the first source be-fore connecting it to the second source.

If there is a power source failure while the TDPT isactive, the control only transfers to the remainingactive power source. The control does not termi-nate the TDPT timer if either source fails while thetransfer switch is in the Neutral position.

Time Delay Elevator (TDEL) Pre-Transfer

Primarily used in elevator applications, this delaysets a time to wait for an elevator pre-transfer sig-nal. This signal allows the elevator to come to acomplete stop before the switch transfers.

The elevator pre-transfer signal and associatedtime delay, is used to signal an elevator control sys-tem that there is an impending transfer or retransfer(i.e., the elevator is going to see a brief power fail-ure).

This delay is disabled during an actual source fail-ure. If the timer is set for more than 0 seconds, then

the control activates the elevator pre-transfer out-put and time delay prior to transferring the transferswitch between two live sources. If the control is ina Test or Exercise sequence, the control adds anadditional delay prior to activating the transfer andretransfer commands. After the TDNE (and/orTDEN) time delay expires, the control activates theElevator output and starts the TDEL timer.

The output relay has two normally open and twonormally closed contacts, rated 5 amps at 380volts.

When the timer expires, the control issues thetransfer (or retransfer) command. When the timeris inactive or expires, the control deactivates therelay output.

The Elevator Pre-transfer Time Delay is configur-able for 0 (disabled), 1, 2, 3, 5, 30, 120, or 300 sec-onds (default = 0 seconds).

Transfer Inhibit and Retransfer Inhibit do NOT af-fect or delay the elevator pre-transfer delay while itis active.

The Override pushbutton or Override input has noeffect on this time delay.

The GTEC control also includes a feature calledElevator Post Transfer Delay that keeps the eleva-tor output active for the same TDEL time period af-ter the transfer switch transfers. For more informa-tion, see Elevator Post Transfer Delay below.

Elevator Post Transfer Delay

The Elevator Post Transfer Delay feature keeps theelevator output active for the same TDEL time peri-od after the transfer switch transfers. Instead of de-activating the elevator output when the pre-transfertime delay expires, the control keeps the output ac-tive and starts the TDEL timer again after it sensesthat the transfer switch has transferred. When theTDEL timer expires the second time, the control de-activates the elevator output. The Elevator PostTransfer Delay is configurable to be enabled (On)or disabled (Off) (default = Off).

4-3

MANUAL OPERATION

The transfer switch has an operator handle formanually transferring the load (see Figure 4-1).Manual operation must be performed by qualifiedpersonnel under NO-LOAD CONDITIONS ONLY.Use the following procedure:

WARNING Manual operation of the transferswitch under load presents a shock hazard thatcan cause severe personal injury or death. Donot attempt to operate the switch manuallywhen it is under load. Disconnect both sourcesof power before operating manually.

1. Verify that the transfer switch is not under load.

2. Open the cabinet door of the automatic trans-fer switch.

3. Remove power to the control by removing theFB fuse (see Figure 4-1).

4. To close Side A:

a. Place the handle on the transmissionshaft.

b. Rotate it upwards until the switch locks.

To open either side (Side A or Side B):

a. Remove the manual operation handle.

b. Press the trip with a screwdriver.

To close Side B:

a. Place the handle on the transmissionshaft.

b. Press and hold Select with a screwdriverwhile rotating the handle upwards until theswitch locks.

NOTE: Remember that the transfer switchtransfers the load to the active powersource. (If both power sources areavailable, it transfers the load to theutility.)

WARNING If not removed, automatictransfer switch operation results in rapidmovement of the manual operator handleand presents a hazard of severe personalinjury. Remove the handle before switch-ing back to automatic operation. Store themanual operation handle in a safe location(for example, the bottom of the cabinet).

5. Make sure the manual operation handle is re-moved from the transmission shaft and storedin a safe location.

Stop the Utility Power Connected LED fromflashing as a result of a failure to connect to ordisconnect from the utility when commanded.

Stop the Genset Power Connected LED fromflashing as a result of a failure to connect to ordisconnect from the genset when command-ed.

Cancel an active exercise period.

The Program Transition (TDPT), Elevator signal(TDEL), and Engine Cool Down (TDEC) time de-lays are not affected by pressing this pushbutton.

Set Exercise Pushbutton

This pushbutton is only used with the integrated ex-erciser and only functions if the External Exercisefunction is disabled (set to Off). Information on con-figuring the control panel is included in Section 5.

The Set Exercise pushbutton is used to:

Set a delayed repeat exercise period when thepushbutton is pressed and held for five sec-onds.

Start an immediate exercise period (that alsorepeats) if the pushbutton is pressed momen-tarily within ten seconds of starting the delayedexercise period.

Cancel a repeatable exercise period if thepushbutton is pressed and held for five sec-onds.

More information on using the integrated exerciseris included on page 4-8.

4-5

TEST WITH OR WITHOUT LOAD

This feature allows a transfer switch operator totest the transfer switch and generator power sys-tem. The test is configurable to be with load or with-out load. A test with load initiates a load transfer. Atest without load just starts the generator and runs itwithout load.

1. Verify that the transfer switch is set to test withor without load, as desired (see Section 5).

2. To start a test, press and hold the Test Push-button for two seconds or ground the RemoteTest input.

3. To end the test, momentarily press the Testpushbutton or remove the ground from the Re-mote Test input.

NOTE: When ending a test with load, you canbypass the retransfer time delay(TDEN) and cause the immediate loadretransfer by pressing the Overridebutton. The generator stops after theengine cooldown time delay (TDEC).

Test With Load Sequence of Events

The following describes the sequence of events ofan GTEC transfer switch during a test with load. Inthis example, TDPT is set to zero, the phase checksensor is disabled, the Transfer Inhibit and Retran-sfer Inhibit inputs are inactive, and TDEL is set tozero.

The utility must be acceptable during the entire testevent. Acceptability is determined by the activesource sensor (undervoltage sensor). If, at anytime, the undervoltage sensor determines that theutility is not acceptable, the Test is terminated.

Before a test can begin, the transfer switch must beconnected to the utility power source and utilitypower must be available.

1. Verify that the transfer switch is set to test withload.

2. Verify that the green Utility Power ConnectedLED on the control panel is lit.

3. Verify that the green Utility Power AvailableLED on the control panel is lit.

4. Press and hold the control panel Test pushbut-ton for two seconds or ground the Remote Testinput to initiate the Test. The Test LED flashestwo times per second for two seconds, ac-knowledging that the test was activated. Oncethe test period starts, the Test LED stays oncontinuously.

5. The control simulates a utility power failure butthe Utility Power Available LED remains lit aslong as the utility is still available.

6. The control starts the TDES timer. After thetimer expires, the control de-energizes thestart relay, closing the start contact to signalthe generator to start.

7. When the generator output is acceptable (theGenset Power Available LED is lit) the controlstarts the TDNE timer.

8. After the TDNE timer expires, the transferswitch transfers to the genset (the GensetPower Connected LED is lit).

9. The control continues to run the generator withthe transfer switch connected to the genset un-til the control panel Test pushbutton is momen-tarily pressed or the ground is removed fromthe Remote Test input.

10. After this action, the control starts the TDENtimer. The Test LED flashes twice per secondfor two seconds to acknowledge the operationand then the Test LED goes out.

11. After the TDEN timer expires, the transferswitch retransfers back to the utility (the UtilityPower Connected LED is lit).

12. Once the transfer switch is connected to utilitypower, the control starts the TDEC timer.

13. After the timer expires, the control energizesthe start relay, opening the start contact to sig-nal the generator to stop.

4-6

Test Without Load Sequence of Events

The following describes the sequence of events ofa GTEC transfer switch during a test without load.In this sequence of events, the generator is startedand runs without load for the duration of the test.

The utility must be acceptable during the entire testevent. Acceptability is determined by the activesource sensor (undervoltage sensor). If, at anytime, the undervoltage sensor determines that theutility is not acceptable, the Test is terminated.

Before a test can begin, the transfer switch must beconnected to the utility and utility power must beavailable.

1. Verify that the transfer switch is set to test with-out load.

2. Verify that the green Utility Power ConnectedLED on the control panel is lit.

3. Verify that the green Utility Power AvailableLED on the control panel is lit.

4. Press and hold the control panel Test pushbut-ton for two seconds or ground the Remote Testinput. The Test LED flashes twice per secondfor two seconds acknowledging that the testwas activated. Once the test period starts, theTest LED stays on continuously.

5. The control de-energizes the start relay, clos-ing the start contact to signal the generator tostart. When the genset starts and producespower, the amber Genset Power AvailableLED lights.

6. The control continues to run the generatorwithout load until the control panel Test push-button is momentarily pressed or the ground isremoved from the Remote Test input.

7. After the control panel Test pushbutton is mo-mentarily pressed or the ground is removedfrom the Remote Test input, the control flashesthe Test LED twice per second for two secondsto acknowledge the operation and then goesout.

8. The control energizes the start relay, openingthe start contact to signal the generator to stop.

Phase Check Sensor

The phase check sensor can be enabled (set toOn) for applications that require a fast transfer of aload between two live sources (both power sourceavailable LEDs are lit). The phase check sensordetermines when the relative phase difference(less than 25 degrees and approaching 0) and thefrequency difference (less than 1 Hz) of the twosources are within specified limits. When all condi-tions are met, a transfer is initiated. If enabled, thephase check sensor is activated after all time de-lays have expired, just before the transfer switchtransfers the load, and only when both sources areavailable. Information on configuring the PhaseCheck On/Off function is included in Section 5.

Return to Programmed Transition

This feature can be used in conjunction with thephase check sensor. If, for some reason the twosources do not fall within the specified limits of thephase check sensor for a period of two minutes,then the control bypasses the phase check sensor,returns to the Programmed Transition sequence ofoperation, and transfers the load. If this feature isenabled, the programmed transition time delay(TDPT) should be set greater than zero. The actualsetting depends on your load.

4-8

GENERATOR SET EXERCISER

Run the generator at least once each week with atleast 50 percent load (if possible). If you do notwant to use the exerciser, use the Test pushbutton,as described earlier in this section, to test the gen-erator set each week.

The control panel includes an integrated exerciserthat is set by pressing the Set Exercise pushbutton.In addition, there may also be an optional fully pro-grammable external exerciser clock installed andwired to a control input (see page 4-10).

If both types of exercisers are available, only oneexerciser can operate at a time. The control panelmust be configured for the type of exerciser beingused. This is done by setting the External Exerciserfunction On or Off. If the integrated exerciser isused, the External Exercise On/Off function mustbe set to Off. If the external exerciser is used, theExternal Exercise On/Off function must be set toOn. If the external exerciser is factory supplied, theExternal Exercise On/Off function is set to On at thefactory. If the external exerciser is not factoryinstalled, the External Exercise On/Off function isset to Off. Information on configuring the control isincluded in Section 5. Information on the optionalexternal exerciser is included later in this section.

Exercise With or Without Load

The exercise with/without load configuration workswith both types of exercisers (default = withoutload) see Section 5. When With Load is se-lected, the load is transferred to the genset. WhenWithout Load is selected, the genset runs with noload for the duration of the exercise period.

Integrated Exerciser

This function is standard and is built into the con-trol. With this exerciser, the exercise period is 20minutes and it repeats every 7, 14, 21, or 28 days(default = 7 days) see Section 5.

The integrated exercise function cannot be usedunless the External Exercise function is disabled(set to Off).

Before an exercise can begin, the transfer switchmust be connected to utility power and utility powermust be available (the green Utility Power Avail-able LED must be lit).

Power Loss Backup

If DC power is removed from the control panel, theexercise clock uses a replaceable lithium battery(part number 4161250) to back up the time set-ting. The battery is good for ten years and doesntneed to be serviced. The battery is attached to thetime chip on the control board.

If no exercise period is set, the Exercise LED is off(see Figure 3-5).

Setting the Integrated Exercise Period

1. Verify that the Exercise LED is off and the Ex-ternal Exercise function is disabled (set to Off see Section 5). If the External Exercise func-tion is enabled, the integral exerciser is dis-abled.

2. To set the exercise start time for a repeat exer-cise period, press and hold the Set Exercisepushbutton for 5 seconds. The Exercise LEDflashes at a rate of twice per second for 5 sec-onds and then stays on when the exercise pe-riod is set. A delayed 20 minute exercise pe-riod will start in 12 hours. At that time, the Exer-cise LED flashes at a rate of once per secondduring the entire exercise period. When the ex-ercise period is over, the Exercise LED quitsflashing and remains on to signify that repeatexercise periods are enabled.

3. To start an immediate exercise period andhave it repeat, momentarily press the Set Ex-ercise pushbutton a second time within tenseconds of starting the delayed exercise peri-od. Momentarily pressing and releasing theSet Exercise pushbutton a second time startsan immediate 20 minute exercise periodinstead of waiting for 12 hours. The ExerciseLED flashes at a rate of once per second dur-ing the entire exercise period. When the exer-cise period is over, the Exercise LED stopsflashing and remains on to signify that repeatexercise periods are enabled.

4-9

Canceling Repeat Exercise Periods

With the control panel Exercise LED on steady,press and hold the Set Exercise pushbutton for 5seconds. The Exercise LED flashes at a rate oftwice per second for 5 seconds and then goes outto signify that repeat exercise periods are can-celled.

Canceling An Active Exercise Period

Active exercise periods can be canceled by press-ing the Override pushbutton on the control panel orby grounding the remote override input (P4-2) onthe back of the control panel.

Power Source Failure During An ActiveExercise Period

If either power source fails during an active exer-cise period, the control immediately terminates theexercise and proceeds with the automatic mode ofoperation.

Exercise Without Load Sequence of Events

1. When an exercise period becomes active, theExerciser LED flashes at a rate of once persecond.

2. The control signals the generator to start andrun for 20 minutes.

3. After the exercise period has ended, the con-trol signals the generator to stop.

4. The Exercise LED stops flashing and remainson to signify that repeat exercise periods areset (unless there are no repeat exercise peri-ods). If there are no repeat exercise periods,the Exercise LED goes out.

Exercise With Load Sequence of Events

1. When an exercise period becomes active, theExerciser LED flashes at a rate of once persecond.

2. The control signals the generator to start.

3. When the generator output is acceptable, thecontrol transfers the load to the generator, fol-lowing the configuration set points.

4. After the exercise period has ended, the con-trol retransfers the load back to the utility, fol-lowing the configured set points.

5. Once the load is connected to utility power, thecontrol runs the genset unload for the durationof the cooldown timer (TDEC).

6. After the TDEC timer expires, the control sig-nals the genset to stop.

7. Unless the repeat exercise periods have beencanceled, the Exercise LED quits flashing andremains on to signify that repeat exercise peri-ods are set. If the exerciser is not set up to re-peat exercises, the Exercise LED goes out.

4-10

OPTIONAL EXTERNAL EXERCISER

The optional external exercise clock is a 7-day,24-hour clock that, when installed, can store andexecute several start/stop programs per day andrepeat exercise periods every week. It can be pro-grammed to run exercise periods at different timeson different days. Unlike the integrated exerciser,the external exercise can schedule an exercise pe-riod for something other than 20 minutes.

If the External Exercise function is enabled (set toOn), then the integrated exerciser is disabled.

NOTE: After a period of inactivity, the clock enterssleep mode and turns off the display. To re-activate the display, briefly press the Menubutton.

Up to 28 programs are available to set exercisestart and stop times. One program is required tostart an exercise period and a second one is re-quired to stop an exercise period.

The exerciser clock also has a built-in test featurethat can be used to initiate a genset start and runcycle.

The exerciser clock contains a lithium battery thatis used as a backup power source. The battery is

not replaceable. When the clock is running off theinternal battery, three flashing dots are displayedbetween the hour and minute values (see Figure4-3). Unless the clock battery fails, exercise pro-grams are stored and are not lost during a poweroutage.
