Operation

EQUIPMENT CAUTIONDo not operate any power converterswith parts missing. Doing so may dam-age the equipment.

The lights begin to operate as soon as power is applied and they flash together synchronously. All lights in the FTB 302-2D, FTB 224-2, and FTB 225-2 Systems com-municate with and are under the control of an FTC 121 System Controller. The controller monitors the status and operating parameters of the lights. The lights can be inter-rogated by the controller, or remotely by using a com-puter and a telephone line connected to the controller. The controller sends light intensity information, sensed by a photocell, to the lights to make them operate in the cor-rect mode for day, twilight, or night lighting. The control-ler sends and receives coded signals over a two-wire shielded communications cable (COMM LINK). Pro-gramming allows a controller to distinguish the signal of each individual light for monitoring and control purposes.

The PCB1 Timing and Trigger Board in each unit con-trols the internal operations of the power converter or beacon. See Section PCB1 Programming and Figure 1-2. PCB1 contains indicator lights that are useful in perform-ing an operational check and troubleshooting.

Marker Lights

System power converters may also operate a tier of marker lights depending on the installation requirements. Each power converter is connected to the designated tier of markers through a Marker Interface Unit that contains a marker power relay, and sensing circuits for total marker current and socket voltage.

An example of a typical installation is shown in Figure 2-14.

FTB 302-2D Light

The FTB 302-2D is a two-part light consisting of a PC 302-2D Power Converter and an associated FH 306 or FH

324 Flashhead. The flashhead has dual red/white opera-tion. The FTB 302-2D usually operates with the simulta-neous operation of FTB 224-2 or FTB 225-2 High Intensity Lights.

In a system that incorporates an AOL, the FTB 302-2D is the sole light of the top tier, and is programmed as Beacon 2 of that tier. The FTB 302-2D contains circuitry for two flash intensity levels and switches from one intensity level to the other in response to a signal from the control-ler. If the system controller should be disconnected or fail, the FTB 302-2D continues to flash at full intensity. Simultaneous flashing with the other lights usually con-tinues even without the controller.

The flashhead and PC 302-2D Power Converter are in separate outdoor enclosures. (See Figure 2-15.) An elec-trical flashhead cable connects these two units. If a very long cable is required, consult Flash Technology by call-ing Customer Service at 1-800-821-5825.

FTB 224-2 System

The FTB 224-2 is a dual system operating in white day and twilight, and red night modes. The FTB 224-2 con-sists of a PC 224-2 Power Converter and a separate FH 204 Flashhead. The flashhead flashes white during the day at 270,000 ECD and during twilight at 20,000 ECD. At night, the red FH 307 Flashhead flashes at 2,000 ECD.

FTB 225-2 System

The FTB 225-2 is a dual system operating in white day and twilight, and red night modes. The FTB 225-2 oper-ates a self-contained Optical Assembly that flashes white during the day at 270,000 ECD and during twilight at 20,000 ECD. At night, the red FH 307 flashhead flashes at 2,000 ECD.

PCB1 Programming

The factory programs PCB1 in each power converter or beacon for its tower address and functions. The program is done internally and with the handheld terminal, which is used to select the specific tier and beacon number of the power converter and associated light that the PCB resides in.

Programming for a position on the structure consists of entering the numbers via the handheld terminal.The num-

FTB 302-2D, 224-2, 225-2 Revision 2 — 06-21-16 1-3

bers for each light is determined by two factors: the light’s height on the structure, know as its tier, and its location or compass point around the structure (Beacon 1 is northerly; Beacon 2 is easterly; Beacon 3 is southerly; and Beacon 4 is westerly). According to FTCA conven-tion, the lowest tier of lights on a structure is designated Tier 1, the next highest tier is Tier 2, and so on.In a light-ing system that incorporates an AOL, the FTB 302-2D is the sole light of the top tier, and is programmed as Beacon 2 of that tier. See section 5.

PCB1 Indicator LEDs and Lamps

PCB1 contains indicators that are useful in performing an operational check and troubleshooting.

Nine indicator LEDs and one neon lamp on PCB1 moni-tor equipment operation. A name imprinted on the board adjacent to the indicator identifies it. The neon lamp has no name next to it. Figure 1-2 shows the location of the LEDs and lamp on the board.

You may pivot the lens open by disengaging quick-release latches. Be careful that the lens or glass window clears nearby objects when you open and close it.

Mounting


Mounting and outline dimensions for the power converter and beacon are shown in Figure 2-1 and Figure 2-2. FTCA does not furnish mounting hardware unless ordered as part of an installation kit. Use the following guidelines for mounting the power converter:

• Ensure that adequate space exists around the equip-ment for access during installation, maintenance andservicing.

• Allow space for air flow around the power converter.

• You must use a bonding strap on a bolt through thepower converter case leg. Connect the strap to the sitegrounding system.

FlashheadMounting dimensions for flashheads are shown in Figure 2-2 through Figure 2-4. The flashhead must be protectedfrom lightning strikes. The flashhead may be mounted topainted or unpainted surfaces. One of the mounting holesin the base of the flashhead contains a built-in electricalground connection. Use the following guidelines formounting the flashhead:

• Use a lightning rod extended above the flashhead toprotect it when it is mounted at the uppermost part ofthe structure.

• Avoid locating a lightning rod where it would preventtilting the lens open or interfere with access by main-tenance or service personnel.

• You must use a bonding strap with a flashhead mount-ing bolt when mounting the flashhead to the structure,using the mounting bolt to fasten the strap to the legthat contains the ground connection.

Flashhead LevelingThe FH 306 and FH 307 Flashheads must be level for cor-rect vertical beam alignment. Two leveling vials—aligned with the mounting feet—are permanently attached to the flashhead assembly. Typically, the mounting surface for

FTB 302-2D, 224-2, and 225-2 Revision 2 — 06-21-16 2-1

the flashhead is level and no adjustments are required. When the flashhead is level, bubbles in both leveling vials are centered. For leveling, use the following guide-lines:

• If adjustment is necessary, raise the appropriatemounting foot with shims or washers. Raising onefoot by 1/16 inch (1.6 mm) tilts the beam about 1/2degree.

• Take extreme care to ensure that all four feet restsnugly against a firm mounting surface before tight-ening the mounting bolts. Failure to do so could resultin serious damage to the base when you tighten thebolts.

Wiring

This manual may not contain all the information about installation wiring required for your installation.

NOTEIf installation drawings prepared specificallyfor your site disagree with information pro-vided in this manual, the site installationdrawings should take precedence. Consultany site-specific installation wiring diagramsupplied with your equipment.

Primary power connections for single-phase systems use the same phase for all beacons.

Installation wiring is shown in Figures 2-16 through 2-18. NOTE: FTCA wiring diagrams define minimum require-ments recommended for satisfactory equipment opera-tion. It is the responsibility of the installer to comply with all applicable electrical codes.

The factory wires the power converters to the voltage and frequency imprinted on the equipment label. Two internal fuses reside in the power converter, sized according to the operating voltage.

You can find conduit and other distribution wiring details on electrical installation diagrams provided by FTCA or others. Installation instructions concerning red light marker fixtures are not part of this manual.

All installation wiring should have an insulation rating of 600 volts. Size power service wiring to satisfy the load

demand of the red light system (if present) and the power converters. Read the notes on the installation wiring dia-grams supplied both in this manual and with the equip-ment.

PC 302-2D Power Converter

For service wiring, consider the voltage, length of the wire run, and the total load (number of lights). Assume a load of 175 volt-amperes per light, and do not permit the line voltage to drop by more than 5% caused by wire resistance. Also assume a load of 175 volt-amperes per light to determine the appropriate slow-acting fuse ratings at the power distribution panel. Use a value of 250 volt-amperes per light to determine fast-acting fuse rat-ings at the power distribution panel and to select a system feeder transformer (if used).

PC 224-2 Power Converter or FTB 225-2 Beacon

For service wiring, consider the voltage, length of the wire run, and the total load (number of lights). Assume a load of 400 volt-amperes per light, and do not permit the line voltage to drop by more than 5% caused by wire resistance. Use a value of 400 volt-amperes per light to determine circuit breaker or slow-acting fuse ratings at the power distribution panel. Use a value of 600 volt-amperes to determine fast-acting fuse rating and to select a system feeder transformer (if used).

FH 306, 307, 324 Flashhead

The wiring between the power converter and flashhead requires five conductors with 600 volts (minimum) insu-lation. Two of the conductors must be #10 AWG. The other three may be #16 AWG (minimum; for mechanical strength) if you are cabling together individual wires. FTCA recommends using FTCA Part Number 6340 shielded cable, which does not require conduit for this application.

For reliable operation, FTCA recommends continuous wiring between the power converters and their associated flashheads without intervening junctions or splices.

If you use FTCA Part Number 6340 cable without electri-cal conduit, you should secure it to the main structure.

2-2 Revision 2 — 06-21-16 FTB 302-2D, 224-2, and 225-2

Securing the CableUse the following method for securing the flashhead cable to a skeletal structure:

1. Run the cable along one of the tower legs and wrapone full turn of two-inch Scotchrap™ #50 tape, or theequivalent, around the cable and tower leg at regularintervals of about 5 feet (1.5 meters).

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

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

4. Perform steps 1 through 3 also directly above andbelow any tower leg flanges that the cable may cross.

Installation Checklist

Complete the following steps before applying power:

1. Equipment Damage:Inspect all equipment for damage.

2. Required Equipment:Verify the received equipment against the packing listto ensure completeness.

3. Power Converter Mounting:Position and mount each unit allowing adequateclearance for opening the covers. Also, use the fol-lowing guidelines:

– Ensure that the case is mounted upright andgrounded.

– Check hardware inside the case to ensure thatthe chassis mounting screws and nuts aretight.

– Ensure that only the bottom of the case hasdrain holes and that they are clear.

– Ensure that no holes are punched or drilled onthe top surface of the case.

– Ensure that air can flow around the case.

– Mount the power converter away from radiofrequency interference (RFI).

4. Power Converter Wiring:Examine the installation drawings and use the follow-ing guidelines:

– Check for proper incoming service voltage.

– Wire each unit according to the instructions.

– Ensure that all three power converters are onthe same main line breaker.

– Check all electrical connections for tightness.

– Check all terminal strip connections for tight-ness.

– Ground the power converter.

5. Flashhead Mounting:

– Ensure that the flashhead lens can be openedwithout striking other objects.

– Level and aim the flashhead.

6. Flashhead Wiring:

– Protect the top flashhead against lightningstrikes.

– Ground the flashhead.

– Check the wiring of the flashhead cable to theflashhead.

– Secure the flashhead cable to the tower. Sup-port and tape the cable to prevent its move-ment by the wind.

After completing all the steps listed above, turn on the power and perform an operational checkout from proce-dures in Section 3 of this manual.

Section 3 — Maintenance and Troubleshooting

Safety

WARNINGBefore proceeding — read the warningon Page iii.

Work safely as follows:

1. Remove rings and watches before opening the equip-ment.

2. Shut off the equipment.3. Remove the component or connect the test instru-

ment.4. Replace the component.5. Turn on the power and test the system.6. Turn off the power and disconnect the test equipment.

Preventive Maintenance

Carry out the following inspection and cleaning proce-dures at least once a year:

1. Verify that moisture does not accidentally enter theequipment through gaskets or seals, or collect as con-densation.

2. Verify that all drain holes are clear.3. Check terminal blocks and relays for evidence of cor-

rosion and electrical arcing. Clean or replace anycomponent that shows evidence of high-voltage dam-age.

4. Check flashtube connections for signs of pitting orarcing. Verify that anode and cathode connections arefirmly tightened.

5. Check all electrical connections for tightness andensure the absence of corrosion or electrical arcing.

6. Clean the inside and outside surface of the glass onthe FH 204 or the FTB 225 Beacon with liquid deter-gent and water. Wipe it gently with a soft cloth orpaper towel.

7. Clean the inside surface of the lens on the FH 306 orFH 307 with an FTCA-approved professional plasticcleaner. Wipe the lens with cheesecloth only. Do notuse regular cloth or paper towels. A lens cleaning kit,

PN 8630801, is available from FTCA. Call Customer Service at 1-800-821-5825.

Storage

No special considerations are required for long-term stor-age of any major assembly, such as the power converter or beacon, flashhead, photoelectric control or any internal component. Circuit boards, when not installed in the equipment, should be kept in antistatic bags or containers.

Diagnostic Testing

RFI Problems

Presence of radio frequency interference (RFI) can cause a light to flash intermittently, at the wrong rate, or at the wrong intensity. RFI can enter the light by way of any wire to or from the unit. For example:

• RFI on primary power wires could cause errors inflash rate and intensity.

• RFI on the COMM LINK wire could cause a light tostay at NITE mode. RFI would not normally cause alight to stay at DAY mode. Also, it could cause lightsand the system controller to malfunction.

• Strong RFI could burn out circuit board components.

While FTCA designed circuits to reject or bypass RFI, complete immunity cannot be guaranteed beforehand. It may be necessary after installation to add external filters or use other methods to reduce RFI entering the equip-ment. FTCA provides all reasonable technical assistance to achieve satisfactory operation.

Diagnostic Troubleshooting

The most effective troubleshooting begins with careful observation of operating behavior. This often leads directly to the cause of the problem. Therefore, become familiar with operation of the power converter or beacon in your system. Note how the LED indicators operate in

FTB 302-2D, 224-2, 225-2 Revision 2 — 06-21-16 3-1

daytime and nighttime conditions. Observe the power converter or beacon at the same time that you observe the LEDs on PCB1. Listen to the sounds of the power con-verter or beacon as it triggers the flashhead in both day-time and nighttime conditions, and watch LEDs and relays as the power converter or beacon switches from day to night and night to day.

Check LED and neon indicators. Are they lit? Are the correct ones lit? Check the power cable and flashhead cable screw connections. Are they tight? Corroded? Has water entered the unit?

Refer to Section 1 — Introduction and Operation for power converter or beacon operation specifics and LED functions. Table 3-1 describes basic operation.

You can control the operation of the power converter or beacon from the System Controller. You can also interro-gate and receive status information from the controller if you have a computer connected to it over a telephone line.

Troubleshooting ChartsTable 3-1 through Table 3-6 provide an approach and some solutions to troubleshooting problems that you may encounter with the lighting systems.

See Table 3-2 to direct you to the correct troubleshooting tables for your system. For example: Table 3-3 lists some symptoms a malfunctioning light might exhibit. Table 3-4 and Table 3-5 correlate these symptoms with component assemblies or conditions that might cause the malfunc-tion.

For example, each item in Table 3-3 is weighted to indi-cate the estimated likelihood that it would be causing the problem. For example, suppose the light does not flash at

all but some of its circuits are still functioning; that is, fuses are not blown, relays operate, and so forth. This is symptom C in Table 3-4. Table 3-4 indicates that symp-

Component Testing

The following procedures describe how to check most of the unit's major electrical components. Always make resistance measurements with the primary power turned off. However, you must make voltage measurements with power applied. Thus, for your safety, carry out all prelim-inary steps such as connecting test leads or circuit jump-ers, or disconnecting existing circuit connections with the power turned off and storage capacitors discharged.


Capacitors

You may test capacitors with an analog ohmmeter capable of measuring one megohm or greater. Use the procedure described below. Resistance measured between the termi-nals of a fully discharged capacitor is initially zero and increases steadily with time if analog ohmmeter leads are left across the terminals. Eventually, an open circuit con-dition occurs. The time it takes for the complete transition depends upon the total amount of capacitance. A capaci-tor, disconnected from other circuitry, is defective if it does not exhibit this behavior. The capacitor must be manually discharged before this measurement can be

repeated. This procedure may not detect a failure that occurs only at high voltage.

A bank of capacitors connected in parallel may be checked as a single unit. First disconnect any leads that connect the capacitors to external circuits. Connect the ohmmeter leads to the terminals of any one of the capaci-tors. If a short circuit is indicated, the individual capaci-tors must be disconnected and checked separately. A shorted capacitor is indicated if the measured resistance does not rise above zero after several seconds of measure-ment.

NOTE

Some instruments may have erroneousreadings when used near a radiatingantenna. Make measurements when thepower to the antenna is turned OFF oruse a meter known to be unaffected byan RF field.

C1 and C2 Capacitor Banks

Check these capacitor banks as described in Section Capacitors. Each bank can be checked as a whole at one time by connecting the meter leads to the terminals of anyone of the individual capacitors in the bank and press-ing the armature of the K3 Bleeder Relay.

C3 and C4 Capacitors

Check these capacitors as described in Section Capaci-tors.

Relays

A malfunctioning relay may have faulty contacts, a sticky mechanism or a defective coil. The first two possibilities may be determined by inspection and manually exercis-ing the armature. A defective coil can be confirmed by measuring the resistance.

K1 — High Intensity Relay

To measure the resistance of this relay, first remove PCB1. The resistance from TB3-8 and TB3-10 or chassis should be approximately 290 ohms.

K2 — Low Intensity Relay

To measure the resistance of this relay, first remove PCB1. The resistance from TB3-7 and TB3-10 or chassis should be approximately 290 ohms.

K3 — Discharge Relay

The K3 coil should measure approximately 290 ohms.

K4 — Transfer Relay


K5 — Marker Relay


L1 — Burst Choke

L1 should measure approximately 15 ohms.

PCB1 — Timing and Trigger Board

Replace this circuit board with one known to be in good condition.

PCB2 — HV Rectifier Board


PCB3 — Filter Detection Board


PCB4 — Sense Board


R1 — Discharge Resistor

R1 should measure 35K ohms.

R2 — Burst Resistor

Each resistor of this component should measure 500 ohms.

3-6 Revision 2 — 06-21-16 FTB 302-2D, 224-2, 225-2

T1 — Power Transformer

To test this transformer, first remove PCB1 and PCB2. Apply power to the unit and measure secondary winding voltages at the terminals indicated.

T3 — Coupling Transformer

Check the continuity of the wires in the primary and sec-ondary windings of this transformer. Ensure that the transformer core is not cracked.

VR1 — Suppressor Assembly

To check this component first remove one of its leads from a fuse block terminal. The measured resistance across VR1 on the x110k ohm scale should be infinite.

Flashhead Component Testing

FLASHTUBE HANDLING PRECAUTIONSFH 204 AND FTB 225-2 OPTICAL ASSEMBLY

Always handle a flashtube by grasp-ing the metallic end caps. Nevertouch the glass section with barehands because skin oils or other con-taminants can shorten flashtube life.

One quick way to determine flashhead malfunction is to switch the flashhead cables on multiple-unit installations. If the flash problem moves with the cable, the problem is likely in the flashhead or the flashhead cable. Of the two possibilities, the flashhead cable is less likely to fail than the flashhead. However, a flashhead cable can fail because of damage caused by improper installation

(stretching excessively or sharp bends), lightning strikes, or physical deterioration (age, cuts, and so forth).

A failing flashtube can produce either defective light out-put, intermittent light output (skip), or no light at all. Most likely, a flashtube will fail completely.

Replace the entire Flashtube Mounting Plate Assembly (A101) in the FH 306 Flashhead (see Section 4 — Spare & Replaceable Parts) if the filter motion is defective or if the flashhead malfunctions with a good flashtube installed.

FT101 — FlashtubeVisually inspecting a flashtube reveals little about its working condition or performance. A darkened envelope does not necessarily mean the light output would be unac-ceptable. Before concluding that a faulty flashtube is responsible for an inadequate flash, first rule out other possible causes such as weak or absent discharge voltage or triggering pulses.

T101 — Trigger TransformerThe measured resistance of the secondary winding (pot-ted assembly) should be approximately 1.5 ohms. Check the ferrite core for cracks. Check the mounting screws for tightness.


Check the continuity of the wires in the primary and sec-ondary windings of this transformer. Ensure that the transformer core is not cracked.

Component Removal and Replacement

This section contains instructions for removal and replacement of most major replaceable components. Sec-tion 4 — Spare & Replaceable Parts provides component location diagrams. For the internal wiring, see Section 2 — Outline, Mounting, and Installation.


C1A - C1x Capacitors

Before removing or replacing a capacitor always make sure it is discharged by checking with a voltmeter directly across the terminals. You may manually discharge a capacitor by placing a resistance (25 watts, 10,000 ohms

FT101 Flashtube

FOLLOW FLASHTUBEHANDLING PRECAUTIONS

Always handle a flashtube by graspingthe metallic end caps. Never touch theglass section with bare hands becauseskin oils or other contaminants canshorten flashtube life.

Removal

1. Loosen two screws that hold each plate that coverseach end of the flashtube on the optical assembly.

2. Disconnect the trigger wire at the P101 ceramic poston the left side of the optical assembly viewed as inFigure 4-4.

3. The flashtube is supplied with connecting leads sol-dered to its ends. Loosen the screw on the end of eachflashtube lead.

4. At one end of the flashtube, use a slender, pointedtool between the end of the flashtube and thespring-loaded clip to pop the flashtube up and out ofthe clip. Do the same at the other end and carefullypull the flashtube out of the optical assembly.

ReplacementObserve the flashtube handling precaution noted previ-ously.

1. Determine the anode and cathode ends: the anode hasred wire soldered to it and red ink or dye on the endof the tube.

2. Ensure that the trigger extension wire has a shortlength of high voltage sleeving installed.

3. Insert the flashtube with the cathode end (no red ink)toward the trigger lead ceramic post.

4. Align the flashtube with the retaining clips at eachend and press it down into the clips one end at a time.Press only at the metallic end caps.

5. Attach the trigger wire (white insulation) at theceramic post P101. Remove any excess wire and donot leave a tail extending from under the screw. Donot forcefully tighten the screw.

6. Attach the red anode wire to its connection directlyabove the tube mounting clip.

7. Attach the black cathode wire of the flashtube to thescrew on the upper end of the plate on the left side ofthe optical assembly viewed as in Figure 4-4.

8. Reinstall each plate on each side of the flashtube andtighten the screws.

Removal1. At the flashtube, remove the large diameter white

wire to the molded secondary winding of the trans-former.

2. At a chassis ground screw remove the small wire tothe transformer secondary winding.

3. Do not disconnect the primary winding wires (seventurns of the hook-up wire).

4. Remove the two 4-40 x 2-inch screws phillips-headscrews that hold the transformer assembly to theplate.

5. At this point note the orientation of the molded sec-ondary winding with respect to fixed features on the

plate because its replacement must be installed with this same orientation.

6. Remove the outer half of the core and lift off themolded secondary winding. The seven turns of thesmall primary winding remain hanging in place.

7. Remove the inner half of the core taking care not touncoil any of the turns of the small primary winding.

Replacement1. Reassemble the small primary and molded secondary

windings over the two halves of the core and attachthe core to the bracket by means of the long screws.Do not overtighten.

2. Reattach the electrical wires. Refer to the internalwiring in Figure FH 204 Flashhead and FTB 225-2Optical Assembly Internal Wiring to verify the con-nections.

Returning EquipmentContact Customer Service at 1-800-821-5825 for a Return Material Authorization (RMA) number before returning equipment.

RepackagingYou must return the equipment in a container that pro-vides maximum protection during shipping and handling.

If the original cartons and packaging material are no longer available, package the power converter or beacon and flashhead separately as described in the following subsections.

Power Converter, Beacon, or FH 204 Flashhead

Package and ship the unit in an upright position; that is, with the feet downward. Pad the power converter or bea-con so that the feet cannot penetrate the box during ship-ment. Box each power converter or beacon separately using a double thickness cardboard container and ade-quate padding. Do not drop. Use appropriate warning labels on the outside of the container.

Flashhead (FH 306, FH 307, FH 324)

Package and ship the flashhead in an upright position. Box each flashhead separately and use adequate padding. Attach the flashhead base to a plate an inch wider than the width of the flashhead (e.g., 3/8" plywood). Use a double thickness cardboard (or wood) container that clears the width, height, and depth of the flashhead by at least one inch (inside dimensions). Use soft packing or a cardboard collar around the lens to prevent tipping inside the con-tainer. Do not drop. Use appropriate warning labels on the outside of the container.

† If you suspect or find any failing parts in the FH 306 flashhead (except the flashtube, RC networks, ceramic spacers, or coupling transformer), replace the entire flashhead baseplate. The flashtube may be replaced as a single unit.

‡ Recommended as a spare part.

* A flashhead mounting plate assembly for the FH 307 flashhead may be mounted in a separate location for testingpower converters or troubleshooting. An alternate scheme is to use it as a portable flashhead to isolate a problemto the flashhead or to the power converter. Doing this may help you avoid climbing to the tower flashheads if youthus immediately prove the problem is in the power converter.

Section 5 — Programming T&T Board P/N 2904410

Connecting the Handheld

Table 5-1 shows the connector pin assignments for the handheld. The receive and transmit directions shown in the table are with respect to the handheld. The DB9 con-nector is located at the top of the handheld programmer.

A 9-pin RS-232 cable is used to connect the handheld to the 9044-01 controller board at connector J2 (9 pin Male connector). Power and ground is provided by this connec-tor.

The same connector J2 on the 9044-01 is also used to connect a computer serial port for the enhanced user interface. This interface is used to set parameters, run pro-duction and vendor tests and display general operating information.

Figure 5-1 FIGURE 5-1 Handheld Program-mer

Using the Programmer

The programmer has a four line LCD display and 24 keys as shown in fig. 5.1.

The following is a general discussion of how the pro-grammer works. See Parameters under the SETUP sec-tion below for more details.

In the discussions to follow the 4 line LCD display will be represented as shown:

L2: **********

L3: **********

L4: **********

All the messages displayed on the LCD will be in capital letters.

The display does not show the L1: etc. this is used to rep-resent line 1, 2, 3 and 4 on the LCD.

Once the handheld programmer is connected to the 9044-01 and power is applied the 9044-01 will automati-cally recognize that the terminal is connected to it and will display the sign on message . Only terminals pro-vided by Flash Technology will work with the 9044-01.

The general format of the sign on message is:

L1: FLASH TECHNOLOGY

L2: BOARD 4990

L3: (Blank or further information)

L4: ENTER TO CONTINUE

Once enter is pressed the first menu is displayed as fol-lows:

L1: PRESS A FUNC KEY

L2: F1. SETUP F2. INFO

L3: F3. SHORTTEST

L4: F4. MODE CHANGE

To continue further a function key must be pressed. The function keys are on the top row of the terminal. See fig. 5.1.

F1: Enters the setup menus, used to configure the 9044-01.

F2: Enters the information menu, used to show a limited amount of useful operating info.

F3: Causes the 9044-01 to perform the short test.

F4: Enters the mode change menu, used to manually change the operating mode (DAY, TWI, and NITE).

Note: The handheld terminal will return to the sign on message from any other menu if no key is pressed within two minutes. The 9044-01 does this to take the serial port out of the handheld terminal mode if the terminal has been removed to allow the serial port to be used for the enhanced user interface. This means that if you remove the handheld terminal and connect a computer to use the enhanced interface you must wait at most two minutes before pressing any key on the computer. You can cycle the power to the 9044-01 for faster access to the computer interface.

RMA Policy Revision 2014B

Return Material Authorization (RMA) Policy

IF A PRODUCT PURCHASED FROM FLASH TECHNOLOGY MUST BE RETURNED FOR ANY

REASON (SUBJECT TO THE WARRANTY POLICY), PLEASE FOLLOW THE PROCEDURE BELOW:

Note: An RMA number must be requested from Flash Technology prior to shipment of any

product. No returned product will be processed without an RMA number. This number will be the

only reference necessary for returning and obtaining information on the product’s progress.

Failure to follow the below procedure may result in additional charges and delays. Avoid

unnecessary screening and evaluation by contacting Technical Support prior to returning

material.

1. To initiate an RMA: Call Flash Technology’s National Operations Center (NOC) at (800-821-

5825) to receive technical assistance and a Service Notification number. The following

information is required before a Service Notification number can be generated:

• Site Name/Number / FCC Registration number/ Call Letters or Airport Designator

• Site Owner (provide all that apply – owner, agent or subcontractor)

• Contractor Name

• Contractor Company

• Point of Contact Information: Name, Phone Number, Email Address, Fax Number and Cell Phone

(or alternate phone number)

• Product’s Serial Number

• Product’s Model Number or part number

• Service Notification Number (if previously given)

• Reason for call, with a full description of the reported issue

2. The Service Notification number will then serve as a precursor to receiving an RMA number if

it is determined that the product or equipment should be returned. To expedite the RMA

process please provide:

• Return shipping method

• Shipping Address

• Bill to Address

• Any additional information to assist in resolving the issue or problem

3. Product within the Warranty Time Period

a. If to be returned for repair;

• RMA # is generated

• Once product is received and diagnosed;

• Covered under warranty – product is repaired or replaced

• Not covered under warranty – quote is sent to the customer for a bench fee of

$350 plus parts for repair

• If the customer does not want the product repaired, a $50 test fee is

charged before being returned

b. If advance replacement;

• Purchase order may be required before the advance replacement order is created

• RMA # is generated and the advance replacement order is created

• Once product is received and diagnosed;

RMA Policy Revision 2014B

• Covered under warranty – credit given back if PO received

• Not covered under warranty – credit will not be applied to PO

• Flash Technology has sole discretion in determining warranty claims. Flash Technology

reserves the right to invoice for parts advanced if the associated failed parts are not

returned within 15 days of issue or if product received is diagnosed to be non-warranty.

• Advance replacements will be shipped ground unless the customer provides alternative

shipping methods.

4. Product outside the Warranty Time Period

a. For Xenon System board repair; a purchase order is required at time of request for a RMA # for a

standard $350 repair bench fee

• RMA # is generated with the PO attached

• If the board is deemed non-repairable after diagnosis, the customer is notified. If the

customer purchases a new board, the repair bench fee is waived. If the customer does

not buy a new board, a $50 test fee is charged before being returned or scrapped.

b. For all other products; no purchase order is required to return the product for diagnosis

• RMA # is generated

• Once product is diagnosed, quote is sent to the customer for a bench fee of $350 plus

parts for repair

• Once the purchase order is received, the product will be repaired and returned

• If the customer does not want the product repaired, a $50 test fee is charged

before being returned or scrapped.

5. After receiving the Flash Technology RMA number, please adhere to the following packaging

guidelines:

• All returned products should be packaged in a way to prevent damage in transit. Adequate packing

should be provided taking into account the method of shipment.

Note: Flash Technology will not be responsible for damaged items if product is not returned in

appropriate packaging.

6. All packages should clearly display the RMA number on the outside of all RMA shipping

containers. RMA products (exact items and quantity) should be returned to:

Flash Technology

Attn: RMA #XXX

332 Nichol Mill Lane

Franklin, TN 37067

7. All RMA numbers:

• Are valid for 30 days. Products received after 30 days may result in extra screening and delays.

• Must have all required information provided before an RMA number is assigned.
