FTB 314-5 Revision 5 – 11-12-2015 1

Section 1 – Introduction and Operation

SystemEach single FTB 314-5 System consists ofa FH 307 Flashhead, a PC 314-5 PowerConverter, a PEC 510 Photocell, and aconnecting cable from the power converterto the flashhead.

The power converter supplies thecontrolling circuitry to convert main ACpower to the required voltages for internaloperation and the discharge energy for theflashhead. It also controls the flash rate.

The photocell senses changes in lightingconditions from day to night and fromnight to day thus signaling the powerconverter to change its operationappropriately. Also, a manual intensityswitch can override the photocell ifrequired.

Note: The FTB 314-5 system isdesigned for operation with an FH 307flashhead and MKR 370 LED markers.Please contact Flash Technology ifsupport for legacy equipment isrequired.

OperationThe PC 314-5 Power Converter operatesan FH 307. It monitors flashheadoperation and signals an alarm if a failureoccurs. The flashhead begins to operate assoon as power is applied. A photocellcontrols intensity for the system.

At night the light flashes red at a rate of 20FPM at an intensity of 2,000 candelas.

Obstructions over 350 feet above groundlevel require several interconnected PC314-5 power converters (typically three)operating the corresponding number offlashheads. A master/slave control line(two-wire) at terminals TB1-4 and TB1-5at the front panel interconnects the units.A sync pulse on the line flashes all thelights in unison and at the same rate.

WARNINGBefore proceeding, read the warning onPage iii. Disconnect the primary powerand wait one minute for storagecapacitors to drain down before openingenclosures.

Power ConverterThe base of the power converter hasmounting feet. The cover lifts off forunrestricted access to the interior. Releasethe latches that secure the cover to removeit for internal access.

FlashheadImportant! The FH 307 does notcontain an interlock switch. Disconnectprimary power to the PC 314-5 and waitone minute for storage capacitors todrain down before opening theflashhead.

The lens assembly is attached to the baseby two hinges and secured by two latches.Disengage the latches and pivot the lensopen. Two lanyards provide support forthe lens assembly when the flashhead isopen. Use a voltmeter to verify that novoltage potential exists between the redand the blue wires of the flashhead cable.

Mounting

Power Converter

Mounting and outline dimensions for thepower converter are shown in Figure 2-1.Flash Technology does not furnishmounting hardware unless ordered as partof an installation kit. Use the followingguidelines for mounting the powerconverter:

Ensure that adequate space existsaround the equipment for accessduring installation, maintenanceand servicing.

Allow space for air flow around thepower converter.

You must use a bonding strap on a boltthrough the power converter case leg.Connect the strap to the site groundingsystem.

FTB 314-5 Revision 5 – 11-12-2015 11

FlashheadImportant! Flash Technologyrecommends installation of one or morelightning rods near the uppermostflashhead. Observe the followingguidelines for lightning rod installation:

The lighting rod(s) must extend 36”above (minimum) and be locatedhorizontally 18” away from theflashhead.

The lightning rod’s location must notinterfere with access by servicepersonnel.

Mounting and outline dimensions for theflashhead are shown in Figure 2-2. Theflashhead may be mounted to painted orunpainted surfaces but must be ensured adirect electrical path to tower steel. Oneof the mounting holes in the base of theFH 307 contains a built-in electricalground connection. You must use abonding strap with a flashhead mountingbolt when mounting the FH 307 to thestructure, using the mounting bolt to fastenthe strap to the leg that contains theground connection.

Flashhead Leveling

The flashheads must be level for correctvertical beam alignment. Two levelingvials—aligned with the mounting feet—are permanently attached to the flashheadassembly. Typically, the mounting surfacefor the flashhead is level and noadjustments are required. When theflashhead is level, bubbles in both levelingvials are centered. For leveling, use thefollowing guidelines:

If adjustment is necessary, raise theappropriate mounting foot with shims orwashers. Raising one foot by 1/16 inch(1.6 mm) tilts the beam about 1/2 degree.

Take extreme care to ensure that all fourfeet rest snugly against a firm mountingsurface before tightening the mountingbolts. Failure to do so could result in

serious damage to the base when youtighten the bolts.

Photocell

Mounting and outline dimensions for thephotocell are shown in Figure 2-4. Thephotocell uses a male 1/2” NPT formounting. Use the following guidelines tomount the photocell:

Locate the photocell where it has anunobstructed view of the polar sky.

It must not view direct or reflectedartificial light. It should not bemounted underneath the controllerwhere it could be shadowed.

The photocell may be supporteddirectly by electrical conduit.

Ensure that the installation iswatertight.

InstallationThis manual may not contain all theinformation about installation wiringrequired for your installation.

Note: If installation drawings preparedspecifically for your site disagree withinformation provided in this manual, thesite installation drawings should takeprecedence. Consult any site-specificinstallation wiring diagram supplied withyour equipment.

Flash Technology wiring diagramsdefine only minimum requirementsrecommended for satisfactoryequipment operation. It is theresponsibility of the installer to complywith all applicable electrical codes.

You can find conduit and otherdistribution wiring details on electricalinstallation diagrams provided by FlashTechnology or others. Installationinstructions concerning MKR 370 ACL-810 marker fixtures are supplied withthe marker kit.

12 Revision 5 – 11-12-2015 FTB 314-5

All communication wiring should have aninsulation rating of 300 volts minimum.All power wiring should have aninsulation rating of 600 volts. Input powerwiring must be sized to satisfy the loaddemand of all connected power converters.Read the notes on the installation wiringdiagrams supplied both in this manual andwith the equipment. See Figure 2-9 forinformation about wiring alarmconnections to the main panel of the powerconverter.

Power Converter Wiring

Installation wiring diagrams are providedin Figures 2-5 and 2-6. Installation notesreferenced in the wiring diagrams arelocated immediately after Figure 2-6. Forservice wiring, consider the voltage, lengthof the wire run, and the total load (numberof lights). Assume a load of 175 volt-amperes per light, and do not permit theline voltage to drop by more than 5% dueto wire resistance. Assume a load of 175volt-amperes per light to determine theslow-acting fuse ratings at the powerdistribution panel. Use a value of 250volt-amperes per light to determine fast-acting fuse ratings at the powerdistribution panel and to select a systemfeeder transformer (if used).

In multiple-unit systems, the master andslave units communicate over the“master/slave” interconnect wiring. Toinsure proper communication between allinterconnected units, the power convertersmust be on the same electrical phase.Also, the “master/slave” interconnectwires must be twisted together at aminimum rate of 6 twists per foot. Therecommended minimum size for controland signal conductors is #16 AWG.

Flashhead Wiring

The power converter and flashhead areinterconnected by the flashhead cable.When Flash Technology Part Number4634000, or equivalent cable, is used, thetwo may be separated by a distance up to600 feet. Consult the factory when agreater separation is necessary. The cablebetween the power converter andflashhead requires four conductors with600 volts (minimum) insulation. Two ofthe conductors must be #10 AWG. Theother two may be #14 AWG (minimum;for mechanical strength) if you are cablingtogether individual wires.

To ensure long-term equipment reliability,use continuous wiring between the powerconverters and their flashheads withoutintervening junctions or splices.

Securing the Cable

Flash Technology recommends thefollowing method for securing theflashhead cable to a skeletal structure:

1. Run the cable along one of the towerlegs and wrap two full turns of two-inch Scotchrap™ #50 tape, or theequivalent, around the cable and towerleg at regular intervals of about 5 feet(1.5 meters).

FTB 314-5 Revision 5 – 11-12-2015 13

2. Wrap three full turns of one-inchScotchrap Filament #890 tape, or theequivalent, over the Scotchrap #50tape.

3. Wrap four full turns of two-inchScotchrap #50 tape, or the equivalent,over the Scotchrap Filament #890 tape.

4. Perform steps 1 through 4 also directlyabove and below any tower leg flangesthat the cable may cross.

Photocell WiringImportant! The photocell must beconnected to the master powerconverter. The uppermost flashheadmust also be connected to the masterpower converter.

The photocell is supplied with pigtails forconnection to the master power converter.The standard photocell (Part # 1855001) issupplied with 20’ of cable. Photocellswith cable lengths up to 75’ are available.

The photocell may be located any practicaldistance from the power converter. Thecable may be spliced to provide additionallength. The recommended minimum wiregauge is #16 AWG if additional length isnecessary.

The photocell terminals on the slavepower converters must have a jumperinstalled from TB1-1 to TB1-2. As an

alternative, a jumper may be installed onPCB1 J18-1 to J18-2.

Installation Checklist

Complete the following steps beforeapplying power to the system.

1. Power Converter Mounting.

Position and mount each unit correctly,allowing adequate clearance foropening the covers. Use the followingchecks:

a. Ensure that the case is mountedupright, is water tight, andgrounded to the site groundingsystem.

b. Check hardware to ensure that allmounting hardware is tight.

c. Ensure that only the bottom of thecase has drain holes and that theyare clear.

d. Ensure that no holes are punchedor drilled on the top surface of thecase.

e. Ensure that air can flow around thecase.

f. Mount the power converter awayfrom radio frequency interference(RFI).

2. Power Converter Wiring.

Examine the installation drawings anduse the following checks:

a. Check for proper incoming servicevoltage.

b. Wire each unit according to theinstructions.

c. In multi-unit installations, allpower converters are on the sameelectrical phase. Connection to thesame breaker will ensure that theunits are on the same phase.

d. Check all electrical connections fortightness.

14 Revision 5 – 11-12-2015 FTB 314-5

e. Check all terminal stripconnections for tightness.

f. Ground the power converter.

g. Wires at master/slave interconnectterminals should be daisy-chainedas a twisted pair between themaster power converter and theslave units. The rate of twist is 6per foot minimum. If a shieldedcable is used, ground the shield.For example, ensure that TB1-4 isconnected to all TB1-4 connectionson all units, and TB1-5 is similarlyconnected.

3. Alarm Wiring:

a. If external alarm detection circuitresponds to closed contacts, ensurethat they are wired to the contactson TB1 that close on alarm.

b. If external alarm detection circuitresponds to open contacts, ensurethat they are wired to the contactson TB1 that open on alarm.

c. Alarm wiring should be lightningand RFI protected: shielded,grounded shield, and in a conduit.

d. If a specific alarm is gangedtogether from all power convertersas one, ensure that the wiringfollows local installationinstructions.

4. Flashhead Mounting.

a. Ensure that the flashhead lens canbe opened without striking otherobjects.

b. Level and aim the flashhead.

5. Flashhead Wiring.

a. Protect the top flashhead againstlightning strikes.

b. Ground the flashhead.

c. Check the wiring of the flashheadcable to the flashhead.

d. Secure the flashhead cable to thetower. Support and tape theflashhead cable to prevent itsmovement by the wind.

6. Photocell.

1. Locate photocell where it viewsunobstructed polar sky with nodirect or reflected artificial lightingstriking it.

2. Mount the photocell vertically toprevent water from entering theunit. Ensure watertightconnections.

3. Connect the photocell to the masterpower converter.

After completing all the steps listed in theInstallation Checklist, turn on the powerand perform an operational checkout fromprocedures in Section 3 of this manual.

FTB 314-5 Revision 5 – 11-12-2015 21

System Wiring Diagram Notes

1. Determine input conductor size by considering the service voltage, the total load demandincluding L-810 markers and the distance from the power source. Assume a load of 175 volt-amperes per light, and do not permit the line voltage to drop by more than 5% due to wireresistance. Input power wiring must be rated at 600V (min).

2. Use L1 and N for 120V, 60 Hz primary power; use L1, L2, and Neutral for 240V, 60 Hz.Unit is factory wired for nameplate voltage.

3. TB4 suitable for up to two #10 AWG conductors per position. Use a junction box if largerconductors are needed and run smaller gauge wire from the junction box to TB4 in eachpower converter.

4. Ground the case leg to the site grounding system.

5. Mount the photocell at the top end of a vertical length of conduit. The photocell must facean unobstructed polar sky. It must not be allowed to view direct or reflected artificiallight.

6. Contact rating 5 amperes, 250 VAC. TB1 terminals 12 to 17 are alarms available on PC314-5A & AE units only. Users alarm circuit not shown.

7. Output wiring to the L-810 markers must be rated at 600V (min). Voltage drop to L-810markers must not be allowed exceed 3% of rated voltage due to wire resistance.

8. Flash Technology Part Number 4634000 or equivalent. Flash Technology recommendsusing a continuous cable without intervening junctions or splices from the flashhead to thepower converter.

9. The flashhead must be ensured a direct electrical path to tower steel. One mounting hole inthe base of the FH 307 contains a built-in electrical ground connection. Use a bondingstrap with a flashhead mounting bolt when mounting the FH 307 to the structure, using themounting bolt to fasten the strap to the leg that contains the ground connection.

10. Flash Technology recommends installation of one or more lightning rods near theuppermost flashhead and beacon. The lighting rod must extend 36” above (minimum) andbe located horizontally 18” away from the flashhead and beacon. The lightning rod’slocation must not interfere with access by service personnel.

11. L-810 marker installation instructions are included with the marker kit.

12. Determine branch conductor gauge by considering the load demand on each branchconductor and the length of the run. Master and slave units must be on the same electricalphase. Splice box (if required) typically furnished by others.

13. The photocell must be connected to the master power converter. A jumper must beinstalled on the photocell input of each slave power converter.

14. Two conductors #16 AWG rated at 300V (min.) twisted together; six twists per foot(min.).

15. Input power, master/slave interconnect, flashhead and beacon wiring are the same onadditional power converter(s) (if installed). Typically, only two levels of L-810 markersare installed on a system consisting of three power converters and associated flashheads.

Section 3 – Maintenance and Troubleshooting

SafetyWARNING

STOP: Before proceeding read thewarning on Page iii.

Work safely, as follows:

1. Remove rings and watches beforeopening the equipment.

2. Shut off the equipment.

3. Remove the component or connect thetest instruments.

4. Replace the component.

5. Turn on the power and test the system.

6. Turn off the power and disconnect thetest equipment.

Preventive MaintenanceCarry out the following inspection andcleaning procedures at least once a year:

1. Verify that moisture has notaccidentally entered the equipmentthrough gaskets or seals, or collectedinside as condensation.

2. Verify that all drain holes are clear.

3. Check terminal blocks and relays forcorrosion or arcing. Clean or replaceany component that shows evidence ofhigh-voltage damage.

4. Check flashtube connections for signsof pitting or arcing. Verify that anodeand cathode connections are firmlytightened.

5. Check all electrical connections fortightness and verify the absence ofcorrosion or electrical arcing.

6. Clean the outside surface of the lenswith liquid detergent and water. Wipeit gently with a soft cloth.

7. Clean the inside surface of the lenswith a Flash Technology approvedprofessional plastic cleaner such asMeguiar’s Mirror Glaze® Clear PlasticCleaner. Wipe the lens withcheesecloth only. Do not use regularcloth or paper towels.

StorageStore equipment indoors when not in use.Circuit boards, when not installed in theequipment, should be kept in antistaticbags or containers.

Diagnostic TestingThe only effective way to check outinterconnected lights is to disconnect themaster/slave interconnect wire that isconnected between power converters andcheck the power converters as single units,as described in Master Unit.

Sync Signal Evaluation

Refer to Figure 2-6. Note that, for eachpower converter, the master/slaveinterconnect line and its return line areconnected to TB1-4 and TB1-5respectively. All units place a pulse on theline, which causes the power converters toflash all the lights at the same time. Thispulse is the synchronization pulse. PCB1in each power converter generates a syncpulse. The first sync pulse to be placed onthe line synchronizes the remaining lights.The width of the sync pulse controls themode of operation.

The sync signal is a pulse and is difficultto evaluate with a meter. You can detectthe sync pulse as an instantaneousmovement of the meter indicator. A digitalmeter with a max-min function

FTB 314-5 Revision 5 – 11-12-2015 27

may capture part of the pulse. This isgenerally a sufficient indication of a pulsebeing present.

Example: A 24V pulse of 16 ms. widthmight read 12V on a 100 ms. capturetime of max-min function.

RFI Problems

The presence of radio frequencyinterference (RFI) can burn outcomponents, cause a light to flashintermittently, at the wrong rate, or at thewrong intensity. RFI can enter the light byany wire to or from the unit. The circuitsreject or bypass RFI, but FlashTechnology cannot guarantee completeimmunity beforehand. After installation,you may find it necessary to add externalfilters or use other methods to reduce RFIentering the equipment. To minimizeinterference, ensure proper installation inaccordance with AC 70-7460, Appendix 1,Figure 2.

Component TestingThe following procedures describe how tocheck most of the unit's major electricalcomponents. Always make resistancemeasurements with the primary powerturned off. However, you must makevoltage measurements with power applied.Thus, for your safety, carry out allpreliminary steps such as connecting testleads or circuit jumpers, or disconnectingexisting circuit connections with the poweroff.

Capacitors

Many digital multimeters have the abilityto measure capacitance. If a digital meterwith this feature is not available, an analogvolt-ohmmeter operating in the resistancemode may be used to evaluate thecondition of a capacitor. The followingmethod assumes an analog instrument witha resistance scale of X100.

Place the meter leads across the terminalsof a fully discharged and isolated (noelectrical connections to other circuits)capacitor. The meter will initially indicatezero ohms and the resistance measurementwill increase if the capacitor is functioningnormally. A capacitor that is isolated fromother circuitry that does not exhibit thisbehavior is defective. The length of time ittakes the meter to reach one meg-ohm is ameasure of the capacitance. For example,the time is about 5 seconds for a 10microfarad capacitor; 10 seconds for a 20microfarad capacitor, and so forth.Manually discharge the capacitor beforerepeating this measurement.

A bank of capacitors connected in parallelmay be checked as a single unit. If a shortcircuit is indicated, the individualcapacitors have to be disconnected andchecked separately. A shorted capacitor isindicated if the resistance does not riseabove zero after several seconds ofmeasurement.

Note: Review documentation suppliedwith the digital multimeter regardingcapacitance measurement.Capacitance tests performed with amultimeter (analog or digital) may notdetect a malfunction that occurs only athigh voltage.

Wiring and Cabling

Wires or cables that move repeatedly willultimately break. Ensure that all cables(the flashhead cable in particular) aresecurely fastened at short intervals to thestructure or other supports.

Inspection

Closely inspect the units and check theconnections against the installationinstructions. Also, a close inspection mayreveal insulation breakdown, anoverheated component, corrosion, looseconnections, faulty relays, incorrecthookup, and so forth.

28 Revision 5 – 11-12-2015 FTB 314-5

Power Converter

Burst Choke (L1)

Measure the resistance of L1 bydisconnecting either the yellow or whiteyellow wire from L1. The resistancemeasurement across L1 should beapproximately 9 ohms.

Relays (K2, K3)

A malfunctioning relay may have faultycontacts, a sticky mechanism, or adefective coil. You may determine thefirst two possibilities by inspection andmanually exercising the armature. You canconfirm a defective coil by measuring theresistance. To measure the resistance ofrelay coils, first remove the wires fromone of the connections to the coil terminalson the relay.

The resistance measurement across thecoil of the K2 Mode Relay or the K3Discharge Relay should be approximately290 ohms.

Note: To easily measure the coilresistance of relay K2, unplugconnector J5 from PCB1. Touch oneof the meter’s probes to the red wire (J5pin 3) and touch the other to the chassisof the 314-5.

To easily measure the coil resistance ofrelay K3, remove the white/blue wirefrom T1 terminal 9. Insert one of themeter’s probes into the connector of thewhite/blue wire and touch the other tothe chassis of the 314-5.

Timing and Trigger Board (PCB1)

Replace this circuit board with one knownto be in good condition. Beforeinstallation, verify that the replacement iscorrectly configured to match the systemtype.

HV Rectifier Board (PCB2)

Replace this circuit board with one knownto be in good condition.

Sense Board (PCB4)

Replace this circuit board with one knownto be in good condition.

Discharge Resistor (R1)

The resistance of R1 between ceramicposts E1 and E2 should be 35,000 ohms.

Note: To easily measure theresistance, remove the blue wire (notthe jumper wire) from C2B and theyellow wire from the burst choke (L1).Insert the meter’s probes into theconnector of each wire.

Burst Resistor (R2)

The resistance of R2 between posts E3 andE4 should be 250 ohms.

Note: To easily measure theresistance, remove the red wire from C3and the white yellow wire from the burstchoke (L1). Insert the meter’s probesinto the connector of each wire.

Power Transformer (T1)

To test the T1 transformer, first removePCB1 and the HV rectifier board (PCB2).Apply power to the unit and measuresecondary winding voltages at theterminals indicated in Table 3-1.

A darkenedenvelope does not necessarily mean thelight output would be unacceptable.Before concluding that a faulty flashtubeis responsible for an inadequate flash, firstrule out other possible causes such asweak or absent discharge voltage ortriggering pulses.

Trigger Transformer (T101)

The measured resistance of the secondarywinding of T101 (potted assembly) shouldbe approximately 150 ohms. Check theferrite core for cracks. Check the mountingscrews for tightness.

Trigger Coupling Transformer(T102)

The coupling transformer should not haveopen windings. An ohmmeter will indicatea shorted winding because of the wire size.Check with an ohmmeter at the wireterminals.

Photocell Testing

Use the following procedure:

1. First, disconnect the photocell. Thesystem should go to night operationafter approximately one minute.

2. In multiple beacon systems, disconnectthe master/slave interconnect line oneach power converter.

3. Operate the manual intensity controlswitch on each power converter inturn.

4. If each power converter operatescorrectly with the manual intensitycontrol switch, troubleshoot thephotocell wiring or the circuits in the

erroneously operating powerconverter.

5. Reconnect all wires.

During daylight, completely block lightfrom entering the photocell. If the systemdoes not enter night mode after a fewminutes, replace the photocell. At night,shine a light on the photocell, if the systemdoes not enter day mode after a fewminutes, replace the photocell.

Component Removal andReplacementComponent location diagrams for thepower converter (PC 314-5, Figure 4-1),and flashhead (FH 307, Figure 4-2) arelocated in Section 4. Internal wiringdiagrams for the power converter (PC 314-5, Figures 2-7 & 2-8) and flashhead (FH307, Figure 2-11) are located in Section 2.

Note the location and color of all wiresthat are disconnected to accesscomponents for replacement. Afterinstallation of replacement components iscomplete, ensure that all wiring agreeswith the corresponding wiring diagram.

The general procedure for removingcomponents is as follows:

1. Obtain access to the component inquestion.

Disconnect completely or partiallythe wiring to components first thatprevent clear access.

2. Completely remove or relocate thesecomponents.

3. Disconnect the wiring to thecomponent that you want to replace.

4. Remove this component.

5. Replace everything in the reverseorder: first the component, then thewiring. In some cases, you may haveto place some wires on the component

30 Revision 5 – 11-12-2015 FTB 314-5

before you fasten it in place, thenreplace the remaining wires.

Most components are relatively easy toaccess for removal. Only those that aremore difficult are described.

Power Converter Components

Capacitors

Before removing or replacing a capacitoralways ensure it is discharged by checkingwith a voltmeter directly across theterminals. Discharge a capacitor byplacing a resistance (25 watts/10,000 ohmsor greater) between its terminals. Directshorting may damage the capacitor, andconnecting the terminals to the equipmentchassis may fail to discharge it.

Remove the fuse for this procedure toprevent application of power if theinterlock switch is accidently pressed.

Removal

1. Disconnect the wires leading tocapacitors.

2. Remove the hold-down screws.

3. Lift the capacitors from their receivingholes.

Replacement

1. Reverse the removal procedure.

2. Verify that wiring is in accordancewith the wiring diagram in Figure 2-7.Wires must be replaced exactly asremoved. In some instances, a quick-connect wire terminal does not seatproperly if it is not placed on theterminal cluster exactly as it wasbefore removal. This occurs byinterference between the insulation onthe wire terminal and the insulationsurrounding their terminal cluster onthe capacitor. Flash Technologyrecommends that you lightly squeezethe quick-connect wire terminals with

pliers before reinstalling them over thecapacitor terminal blades.

Manual Override: FixedIntensities

You may manually override automaticintensity control (as when the manualintensity override switch S2 is set toAUTO), but only if no synchronizationline connects to other lights. Remove anywire from external circuitry attached to themaster/slave interconnect terminals.Manual control is intended for temporarypurposes (testing) only. Selecting Day orNight operation with the manual overrideswitch activates an eight hour timer.Automatic intensity control will resumeafter eight continuous hours of operationin the manual override position (Day orNight).

Daytime

Switch the Intensity Control Switch (S2)to DAY.

Night

Switch the Intensity Control Switch (S2)to NIGHT.

PCB1 Indicator Lamps

See Section 1 for a description of LEDindicators on the PCB1 board for systemcheckout.

Standard System

The following procedures check normaloperation.

1. Check Normal Daytime Operation:Apply power to the system (pull theplunger of the interlock switch orswitches outward to the serviceposition). Ensure that the manualintensity override switch or switchesare set to AUTO and verify that thedaytime responses at each powerconverter in the system are the same asthose shown in Table 3-2 for Daytimeoperation.

Note that the red strobe is notflashing.

2. Check Normal Nighttime Operation:Place an opaque (blocks all light)cover over the photocell and verifythat the red night responses at eachpower converter in the system are thesame as those shown in Table 3-2 forNighttime operation.

NOTE: A minute may pass before thephotocell responds to the darkenedcondition after power is applied.

Note that the red strobe is flashingat the nighttime intensity.

3. Check Alarm Sensing: Removeprimary power and disconnect theblack wire on TB2. Cover thephotocell as described in Step 2.Apply primary power and verify thefollowing:

The red strobe does not flash. The RED ALM LED (I13) is lit

after three missed flashes. The NITE ERR LED (I15) is lit. The alarm circuit operates

according to installationrequirements.

4. Restore the Equipment AfterChecking: Replace all disconnectedwires. Uncover the photocell. Ensurethat the manual intensity overrideswitch is in the AUTO position.

5. If Any Responses are Not Normal:If any of the responses above are notexactly as described, proceed toTroubleshooting.

Troubleshooting

Effective troubleshooting procedures,beginning with the observation of systembehavior, often lead directly to a faultycomponent or other abnormal condition.System-level problems affect all lights in amultiple-light system in the same way.

FTB 314-5 Revision 5 – 11-12-2015 35

Unit-level problems originate in a singlelight. However, some unit-levelmalfunctions can affect the entire multi-light system. Use Table 3-3 fortroubleshooting a single unit and Table 3-4for the system.

When you trace a problem to a specificcomponent, see Component Testing andComponent Removal and Replacement forfurther assistance.

Master Unit

A stand-alone unit is a single FTB 314-5.A master unit is similar to a stand-aloneunit, except that it is the controlling unit ina multiple-light system. The photocell anduppermost flashhead must be connected tothe master unit. Mode control andsynchronization information are providedby the master unit to the connected slaveunits over the interconnect cableconnected at TB1 -4 and TB1-5.

1. Disconnect the black master/slaveinterconnect wire at TB1-4.

2. Set the manual intensity overrideswitch S2 to NIGHT.

3. Verify the Night time responses are thesame as those in Table 3-2.

4. Verify that the strobe is operating atnight time intensity (low intensity).

5. Check the synchronization signal atTB1-4 (labeled “Black”) with avoltmeter as described in “Sync SignalEvaluation”. Use the intensity controlswitch to step the unit from oneintensity to the other, or cover anduncover the photocell. If thesynchronization signal is absent,replace PCB1. A signal responsecould indicate a slave unit problem orRFI (see Slave Unit, and RFIProblems).

Note: The FTB 314 system does notflash during day mode operation.

6. Reconnect the black master/slaveinterconnect wire.

7. Place the manual intensity overrideswitch in the AUTO position.

Slave Unit

A slave unit receives intensity informationfrom a master unit over the master/slaveinterconnect wires at TB1.

1. Disconnect the black master/slaveinterconnect wire at TB1-4. The unitwill go into day operation.

Note: The FTB 314 system does notflash during day mode operation.

2. Verify the Daytime responses are thesame as those in Table 3-2.

3. Check the synchronization signal atTB1-4 (labeled “Black”) with avoltmeter. The sync pulse must bepresent as described in “Sync SignalEvaluation”. Check wiring if sync isnot present.

4. Select NIGHT at the manual intensityoverride switch. The unit will go intonight mode with the strobe flashing atnight intensity (low intensity).

5. Check the synchronization signal onthe wire removed from TB1-4 with avoltmeter, as described in “SyncSignal Evaluation”. An absent pulsemay indicate another malfunctioningunit connected to the master/slaveinterconnect cable or RFI (see RFIProblems).

6. Reconnect the master/slaveinterconnect wire to TB1-4.

7. Place the manual intensity overrideswitch in the AUTO position.
