Read these instructions completely and become fa-miliar with safety warnings, cautions, and proce-dures before starting the installation.

WARNING Incorrect installation, service, orparts replacement can result in severe personalinjury, death, and/or equipment damage. Ser-vice personnel must be trained and experi-enced to perform electrical and mechanicalcomponent installations.

CONTROL INSTALLATIONWARNING The transfer switch presents a

shock hazard that can cause severe personalinjury or death. Before beginning installation,remove all sources of AC power. If a generatorset provides emergency power, move the gen-erator set operation selector switch to Stop, dis-connect AC line power, disconnect the batterycharger from its AC power source, and discon-nect the starting battery (negative [] lead first).

1. Remove all sources of power from the transferswitch in the following order.

a. Move the operation selector switch on thegenerator set to Stop.CAUTION Always disconnect a battery

charger from its AC source before discon-necting the battery cables. Otherwise, dis-connecting the cables can result in voltagespikes high enough to damage the DC con-trol circuits.

b. If there is an external battery charger, dis-connect the battery charger from its ACpower source.

WARNING Ignition of explosive batterygases can cause severe personal injury. Donot smoke or cause any spark, arc, or flamewhile servicing batteries.

WARNING Accidental starting of the gen-set can cause severe personal injury ordeath due to electrocution or contact withmoving parts. Disconnect the starting bat-tery cables, before performing service. Bat-

Manual Restore Option

When installed, the optional Manual Restore keyswitch (kit 5411216) is located on the front panelbelow the Control Panel (see Figure 5).When the switch is set to Retransfer Inhibit, theload remains connected to Source 2 after a transfer.When the switch is set to Force Retransfer to Util-ity, 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 Retransfer Inhibit and Com-mon of a terminal block (TB1-7 and TB1-8 in Figure6). Closing the contact enables the feature andopening the contact disables it.NOTE: The terminal block is not included in this

kit.

CONTROL PANEL

The control panel (see Figure 7) includes controlfunction LEDs, ATS status LEDs, and three mem-brane pushbuttons.

Control Function LEDs

The control panel includes eight LEDs that displaycodes that indicate various control functions thatcan be configured. The first five LEDs display thefunction code and the last three LEDs display thevalue code for the displayed function. For informa-tion on configuring these functions, see page 15.

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 outputvoltage.

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 powerbefore 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.

This LED flashestwice per second when the Set Exercise pushbuttonis pressed to set or cancel an exercise. This LEDflashes once per second during an active exerciseperiod.

PUSHBUTTON OPERATION

The following describes operation of the threepushbuttons located on the control panel.

Test PushbuttonThe Test pushbutton is used to: Start a genset test, with or without load. The

Test LED flashes and stays on if the Testpushbutton is pressed and held for two sec-onds.

Terminate a genset test. The Test LEDflashes for two seconds and goes out if theTest pushbutton is momentarily pressed.

The Test pushbutton is also used in the Configura-tion Mode to step through the function codes (seepage 15).Override Pushbutton

The Override pushbutton is used to:

Terminate the following system time delays: Time Delay Engine Start (TDES) Time Delay Normal to Emergency (TDNE) Time Delay Emergency to Normal (TDEN)

Bypass the TDNE timer and transfer the loadimmediately during an active Transfer Inhibitinput.

Bypass the TDEN timer and retransfer theload immediately during an active RetransferInhibit input.

Stop the Utility Power Connected LED fromflashing as a result of a failure to connect toor disconnect from the utility when command-ed.

Stop the Genset Power Connected LEDfrom flashing as a result of a failure to con-nect to or disconnect from the genset whencommanded.

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.

The Override pushbutton is also used in the Config-uration Mode to step through the value codes (seeModifying the Control Panel Configuration, start-ing on page 15).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).The Set Exercise pushbutton is used to:

Set a delayed repeat exercise period whenthe pushbutton is pressed and held for fiveseconds.

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

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

Once the control has been installed, it will need tobe configured if your installation requires differentsettings from what is shown in Table 2. While the fol-lowing pages provide information on all of the func-

tions that are available, only the system settingsmust be set to match your system specifications inorder for the control to operate the transfer switchwhen power is applied. You may wish to adjust addi-tional settings for better performance. Other set-tings may only need to be changed when exercisingor testing the unit with or without load.Descriptions of these functions are listed below.The functions are divided into six categories.

System settings Time Delays Using the integrated exerciser Exercising with or without load Testing with or without load Sensor settings

Information on how to configure the control in orderto adjust these settings in on page 15.

SYSTEM SETTINGSBefore power is applied to the transfer switch, thefollowing system settings must be set on the con-trol.

System Nominal VoltageEleven possible nominal voltages are available withthis control. The nominal voltages are divided intotwo tables. Voltage Table 1 includes 110, 115, 120,127, 139, and 220 VAC. Voltage Table 2 includes230, 240, 255, 277, and 347 VAC. The default set-tings are Voltage Table 2, and 240 VAC. To changethe nominal voltage, you must first configure thecontrol for the appropriate voltage table and thenconfigure it for the appropriate voltage value.

System Nominal FrequencyThe control can be configured for either 50 or 60 Hz(default = 50 Hz).System PhaseThe control can be configured for either a singlephase or a three phase system (default = threephase).

of 24C685

TIME DELAYS

A transfer switch control uses various time delays tobreak from one power source and reconnect toanother source. The control panel can be used toadjust these time delays.In the following descriptions of time delays, it is im-portant to remember that:

When the transfer switch is connected toNormal, it is connected to the utility powersource.

When the transfer switch is connected toEmergency, it is connected to the Gensetpower source.

When the transfer switch is in the Neutralposition, it is not connected to either powersource.

Time Delay Engine Start (TDES)This time delay prevents the generator from startingduring brief utility power interruptions. This timerstarts the instant the utility fails, as detected by theUndervoltage 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 the startcontact signalling the generator to start. The timeris not reset until utility power returns. If the Overridepushbutton is pressed or the Override input isgrounded while the TDES timer is active, the TDEStimer immediately expires.

Time Delay Engine Cooldown (TDEC)This time delay allows the generator to cool down(under no load conditions) before the control turns itoff.

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

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 genera-tor 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. TheTDEN timer will not begin if a Retransfer Inhibit inputis active.

of 24C685

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 switch trans-fers from one source to the other with no neutralposition delay.

The control activates a Program Transition TimeDelay (TDPT) whenever the transfer switch has dis-connected 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-TransferPrimarily 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, thenthe control activates the elevator pre-transfer out-put and time delay prior to transferring the transferswitch between two live sources. If the control is in aTest 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 10 amps at 600volts.

When the timer expires, the control issues thetransfer (or retransfer) command. When the timer isinactive or expires, the control deactivates the relayoutput.

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 affector delay the elevator pre-transfer delay while it is ac-tive.

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

The TS1311 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 DelayThe 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) ordisabled (Off) (default = Off).

USING THE INTEGRATED EXERCISERIf your installation includes an external exerciser, beaware that only one exerciser can operate at a time.The control panel must be configured for the type ofexerciser being used. This is done by setting the Ex-ternal Exerciser function On or Off. If the integratedexerciser is used, the External Exercise On/Offfunction must be disabled (set to Off). If an externalexerciser is used, the External Exercise On/Offfunction must be enabled (set to On). The ExternalExercise On/Off function of the control included inthis kit is is 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 AvailableLED must be lit).

of 24C685

Exercise Repeat IntervalThe exercise period of the integrated exerciser is 20minutes and it repeats every 7, 14, 21, or 28 days(default = 7 days).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 Modifying the Control Panel Configura-tion, starting on page 15). If the External Exer-cise function is enabled, the integral exerciseris disabled.

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 peri-od is set. A delayed 20 minute exercise periodwill start in 12 hours. At that time, the ExerciseLED flashes at a rate of once per second duringthe entire exercise period. When the exerciseperiod is over, the Exercise LED quits flashingand remains on to signify that repeat exerciseperiods are enabled.

3. To start an immediate exercise period andhave it repeat, momentarily press the Set Exer-cise pushbutton a second time within ten sec-onds of starting the delayed exercise period.Momentarily pressing and releasing the SetExercise pushbutton a second time starts animmediate 20 minute exercise period insteadof waiting for 12 hours. The Exercise LEDflashes at a rate of once per second during theentire exercise period. When the exercise peri-od is over, the Exercise LED stops flashing andremains on to signify that repeat exercise peri-ods are enabled.

Canceling Repeat Exercise PeriodsWith 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 out tosignify that repeat exercise periods are cancelled.

Canceling An Active Exercise PeriodActive 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 PeriodIf either power source fails during an active exerciseperiod, the control immediately terminates the exer-cise and proceeds with the automatic mode of op-eration.

Power Loss BackupIf DC power is removed from the control panel, theexercise clock uses a replaceable lithium battery(part number 4161250) to back up the time setting.The battery is good for ten years and doesnt needto be serviced. The battery is attached to the timechip on the control board.

If no exercise period is set, the Exercise LED is off(see Figure 7).

EXERCISING WITH OR WITHOUT LOADThe control includes an exercise with or withoutload function (default = without load). When WithLoad is selected, the load is transferred to the gen-set during the exercise period. When WithoutLoad is selected, the generator set runs with noload for the duration of the exercise period.

Exercise Without Load Sequence ofEvents

1. When an exercise period becomes active, theExerciser LED flashes at a rate of once per sec-ond.

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

3. After the exercise period has ended, the controlsignals 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 Events1. When an exercise period becomes active, the

Exerciser LED flashes at a rate of once per sec-ond.

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.

of 24C685

4. After the exercise period has ended, the controlretransfers the load back to the utility, followingthe 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.

TESTING WITH OR WITHOUT LOAD

This feature allows a transfer switch operator to testthe transfer switch and generator power system.The test is configurable to be with load or withoutload. A test with load initiates a load transfer. A testwithout 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 Modifying theControl Panel Configuration, starting on page15).

2. To start a test, press and hold the Test Pushbut-ton for two seconds or ground the Remote Testinput.

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 of atransfer switch during a test with load. In this exam-ple, TDPT is set to zero, the phase check sensor isdisabled, the Transfer Inhibit and Retransfer Inhibitinputs are inactive, and TDEL is set to zero.

The utility must be acceptable during the entire testevent. Acceptability is determined by the active

source 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 the tim-er expires, the control de-energizes the startrelay, closing the start contact to signal the gen-erator to start.

Test Without Load Sequence of Events

The following describes the sequence of events of atransfer switch during a test without load. In this se-quence of events, the generator is started and runswithout 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 Available LEDlights.

6. The control continues to run the generator with-out load until the control panel Test pushbuttonis momentarily pressed or the ground is re-moved from the Remote Test input.

7. After the control panel Test pushbutton is mo-mentarily pressed or the ground is removed

from 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.

SENSOR SETTINGSUtility Sensor

The utility sensor monitors all phases of the utilityfor undervoltage conditions. Both the pickup anddropout set points are adjustable. The set points arelisted in Table 3. Refer to Modifying the ControlPanel Configuration section on page 16 for infor-mation on how to make adjustments.

Generator Sensor

The generator sensor is a single phase sensor thatmonitors undervoltage and underfrequency condi-tions. All the pickup and dropout settings are fixedand are not adjustable. The genset undervoltageand underfrequency set points are listed in Table 4.

Phase Check Sensor

The phase check sensor can be enabled (set to On)for applications that require a fast transfer of a loadbetween two live sources (both power source avail-able LEDs are lit). The phase check sensor deter-mines when the relative phase difference (less than25 degrees and approaching 0) and the frequencydifference (less than 1 Hz) of the two sources arewithin specified limits. When all conditions are met,a transfer is initiated. If enabled, the phase checksensor is activated after all time delays have ex-pired, just before the transfer switch transfers theload, and only when both sources are available.

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 of

operation, 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.

MODIFYING THE CONTROL PANELCONFIGURATION

IntroductionThe control panel has a series of eight LEDs thatdisplay codes that indicate various control functionsthat can be configured. The first five LEDs displaythe function code and the last three LEDs displaythe value code for the displayed function (see Fig-ure 7). A listing of the control functions (includingthe function and value codes) is included in Table 5.For normal (automatic) operation, the control mustbe in Automatic Mode. With the exception of theTest LED, the function and value LEDs are not litduring automatic operation (Automatic Mode).The control must be in Configuration Mode tomodify the value code for the various control func-tions. Information on how to access ConfigurationMode and modify the control panel configuration isincluded on the following page.

Accessing the Front Panel ConfigurationEditorWARNING AC power within the cabinet and the

rear side of the cabinet door presents a shockhazard that can cause severe personal injury ordeath. Use extreme caution to avoid touchingelectrical contacts whenever the cabinet door isopen.

The transfer switch must be installed correctly, withDC power (battery power) present, before any ad-justments to the configuration can be made. WhenDC power is present, either the Utility Power Con-nected LED or the Genset Power Connected LED islit. If neither LED is lit, open the transfer switch doorand place the transfer switch in the Normal or Emer-gency position.

AC power (utility or genset) may be present butdoesnt have to be present to configure the controlpanel.

1. Open the transfer switch door.

2. Configuration Mode is selected by movingthe small slide switch located on the back of thecontrol panel to the right (configuration mode)position. The switch is located near the bottomedge of the printed circuit board (see Figure 9).The switch is partially hidden to prevent acci-dental operation.

NOTE: The Configuration Mode can be entered atany time, but once it is selected, all automat-ic operation is suspended.

Modifying the ConfigurationCAUTION Incorrect settings can result in the

transfer switch failing to operate correctly. Only

authorized trained personnel should makechanges to the control function settings.Default settings are shown in bold italics in Table 5.To adjust settings,

3. Slide the selector switch to the ConfigurationMode position. TDES is always the first func-tion shown when entering Configuration Mode.

4. Press the Test pushbutton to scroll through thevarious control function codes displayed withthe first five LEDs (see Table 5). The black-filled circles indicate which LEDs are lit for thefunction and value codes listed.

5. Once the desired function is selected, pressthe Override pushbutton to change the associ-ated value code displayed with the last threeLEDs.

6. When configuration is completed, return theselector switch back to the Automatic Modeposition.
