SILENT SENTINELADVANCE WARNING ARROW PANELS

SERVICE, REPAIR & TROUBLESHOOTING


The SILENT SENTINEL is a highlyreliable, low maintenance, state of theart piece of equipment. However, eventhe best of things require service andrepair from time to time. When this timecomes you wi l l f ind the SILENTSENTINEL very user friendly. Theservice and troubleshooting proceduresincluded in this manual will step youthrough most common problems and getyour unit back on line quickly. If you areunable to solve a problem on your own,our highly trained and knowledgeablefactory personnel are always availableto help you as needed.

LAMP REPLACEMENT

In the event that a lamp should fail, usethe following procedure to insure correctlamp installation.

To remove defective lamp, raise thearrow panel approximately one and ahalf to two feet above the travel position.Loosen the three phillips head screwssecuring the plastic hood over thedefective lamp one full turn. Place handon lamp lens and turn the shroud a fewdegrees counterclockwise to unlock andremove. Allow the hood to slide over thehand that is holding the lamp in placedown onto your arm.

Remove the lamp from the shroud andcarefully remove the push-on terminalsand wires from the back of the lamp.

Now install the wire connectors onto theterminals on the new lamp.

Place the lamp back into the shroud.Make certain that the tab on the edge of

SERVICE & REPAIR

the lamp is inserted into the keyway ofthe shroud. This is very important!Correct lamp lens position will insurethat the beam pattern is properly oriented.

While holding the lamp in position withthe hand and arm with the hood, slide thehood up and over your hand and installthe hood onto the screws in the panel.Place the hood over the screws so theholes line up with the screws and dropsinto place. Turn the hood a few degreesclockwise until it locks in place andtighten the three phillips screws that holdit in place. Do not over tighten thescrews.

After lamp replacement is complete,check the arrow board for proper functionof arrow patterns.

CONTROL MODULE

All control functions necessary to theoperation of the SILENT SENTINEL areintegrated into one easy to servicecontrol module located either in thebattery compartment or the arrow panel.

To remove the control module, simplyremove the fasteners securing the controlmodule and carefully remove the controlmodule from either the arrow panel orthe battery box compartment. Do notopen the control module enclosure orattempt to repair the control module inany manner.

NOTE: There are no field serviceablecomponents in the control module. Thecontrol module circuit board containssophisticated electronic circuitry andsome surface mount devices which re-quire special equipment and techniquesfor repair and replacement. Any attempt


to service the circuit board which re-sults in damage will void the warranty.Field repairs to the control module cir-cuit board must not be attempted. Thecontrol module can only be repaired byskilled technicians at the factory.

If control module is to be replaced, thenext step is to disconnect the cablesfrom the module. All of the connectorsare self locking so they will not comeloose during normal operation.

To remove the power cables (P1 andP3), using the thumb and forefinger,squeeze the locking levers on either endof the connector housing and slide thecable and connector out of the socket onthe circuit board (Molex type connec-tors) or loosen rotating locking ring andremove connector (AMP CPC type con-nectors).

To remove the control cable (P2), loosenthe locking thumbscrews on either sideof the connector and slide the plug out ofthe PCB connector.

To reinstall the control module back intoits housing simply reverse the aboveprocedure following the cable schedulelisted below.

CABLE CONNECTOR

Battery Power P1(4 Wire Bundled or Female CPC)Arrow Panel Control P2(Gray Jacketed 37 pin D-Sub)Solar Array Power P3(2 Wire Jacketed or Male CPC)

NOTE: It will take approximately 10-20seconds for the control module to re-initialize after it is first powered. If thecontrol module will not function after it isinstalled, disconnect P1, wait one minute

and reconnect it to re-initialize the con-trol module.

Make sure that all of the connectors areproperly seated and their locking mecha-nisms are engaged. Install and tightenthe locking thumbscrews on connectorP2. Use only finger pressure to tightenthe screws. Do not over tighten.

Check all control functions after controlmodule has been installed.

Check for the proper functioning of theSOLAR CHARGER indicators with unitexposed to sunlight. The VOLTAGE OKand the CHARGING indicators shouldbe on even on cloudy and overcast days,particularly during the middle of the daywhen the sun is high in the sky.

Make certain that BATTERY LEVELindicators are functioning properly. TheBATTERY LEVEL indicator lamps dis-play the approximate charge level of thebattery bank by displaying the range ofvoltage as indicated below.

NORMAL Between 12 & 13

RECHARGE Between 11 & 12

RECHARGE Below 11 (flashing)

LOW Below 10.7BATTERY (shutdown)

Check all arrow panel patterns for cor-rect display.


POWER & CONTROL CABLES

The power and control cables all haveeither connectors or terminals on bothends to accommodate easy repair orreplacement in the event they becomedamaged or destroyed.

The solar array power cable can be re-moved and replaced by disconnectingboth leads at the terminals in the junctionbox located on the underside of the solarpanel. The cable ties must be removedfirst by cutting them with a diagonal cut-ter; be careful to avoid damaging thecable jacket. It may be necessary toremove the nuts and lockwashers thathold the solar array in place and lift upthe solar array to gain access to theelectrical terminals in the junction boxeslocated on the underside of the solarpanels.

Remove the cover to the solar panel'sjunction box - loosen the terminal screwsand remove the snap spade terminalsfrom the screws. Loosen the strain reliefand carefully pull the wires though thestrain relief. Remove the control mod-ule and pull the cable through from theinside of the compartment until it is freefrom the strain relief. Disconnect thecable from the control module. The cablecan now be repaired or replaced. Besure to observe correct polarity whenreconnecting the wires in the conduitbody or to the solar panel terminals:White or red to positive (+) and black tonegative (-).

The arrow panel control cable can alsobe easily serviced or replaced by follow-ing the above steps first to remove thesolar array power cable, then continuingon to remove the control cable. Discon-nect the control cable from the arrowpanel frame by turning the locking ring

counterclockwise and removing the con-nector and cable from the receptacle.Now disconnect the control cable fromthe control module and remove the fourrivets securing the cable access portcover on the outside of the battery com-partment. The control cable can be re-moved from the unit. Note that the cableaccess port cover is an integral part ofthe control cable assembly and is sup-plied with the replacement control cable.

Reverse the above procedure to installrepaired or replacement cables. Installthe arrow panel control cable first fol-lowed by the solar array power cable(the rivets may be replaced with #10 x1/2" machine screws and nylon lock nutsif 3/16" pop rivets are unavailable). Makesure that there is enough cable at thepivot point of the arrow panel supportframe and at the pivot point of the solararray mounting frame to accommodatethe movement of the lifting mechanismduring normal operation. Be sure to useUV stable (black) cable ties to securethe cables to the cable tie anchors andto the trailer frame.

The battery power wire harness can beremoved by disconnecting the wire leadsfrom the batteries and pulling themthrough the dividing bulkhead into thecontrol module housing. Broken or dam-aged wires in the battery power harnesscan be replaced by using 12-16 AWGstranded and tinned wire with PVC insu-lation. Always make sure that the bat-tery connections are tight and kept dry tominimize corrosion around the termi-nals.

Broken or damaged pins in the arrowpanel wire harness connector, locatedin the frame of the arrow panel, can bereplaced by standard D-subminiatureconnector terminals available at your


local Radio Shack store. Remove thefour screws holding the connector to theframe and withdraw the connector fromthe frame. There should be enough wireinside the panel to allow the connectorto come out about 8 inches. Now, simplylocate the defective pin and its associ-ated wire, pull the wire and pin out of theback of the connector housing, crimp ona new terminal, and insert it into the backof the connector housing. Push it in untilit clicks and locks into place.

More extensive damage to the arrowpanel wire harness may necessitate dis-mounting the panel from the trailer orframe and removing the back panel togain access to the inside of the panel.While removing the rear panel from thearrow panel carefully disconnect theleads going to the rear panel indicatorsso the rear panel can be completelyseparated from the panel assembly. Youwill now have complete access to thearrow panel wire harness. You can re-pair or replace broken or damaged wiresin the harness or install a complete newwire harness assembly available fromthe factory.

You will notice that everything used inthe construction and assembly of theSILENT SENTINEL is modular in na-ture and very easy to repair or replace.

Rear panel indicators can be removedand replaced by disconnecting theirleads from the arrow panel wire harnessassembly, removing the nut from the in-side of the rear panel and sliding theindicator assembly out of the mountinghole. Install the replacement indicatorby reversing the procedure.

The trailer lighting wire harness can berepaired or replaced as necessary. If anew or different type of connector is

installed, be sure to follow the color codeas listed below:

BATTERY BANK

Providing proper care and maintenancefor the batteries in the SILENT SENTI-NEL will optimize the level of perfor-mance and maximize their life expect-ancy. It is very important to maintain thelevel of electrolyte in the batteries abovethe plates. If the electrolyte level is al-lowed to drop below the plates, that por-tion of the plates that have been ex-posed is permanently damaged and willnot recover after the electrolyte level isreturned to normal.

Use only clean distilled water and filleach cell to the indicating ring. A com-mercially available battery filling con-tainer will simply and safely fill each cellto the appropriate level automatically.

The other primary factor in determiningservice life for a bank of batteries is thedegree of plate sulfation. The pulsewidth modulated charge control circuitused in the SILENT SENTINEL controlmodule helps to minimize plate sulfation.However the best situation to minimizethe accumulation of sulfides is to peri-odically agitate the batteries. Normallythe movement that the batteries will ex-perience when the unit is moved fromone work zone to the next is sufficient tomix sediment in the bottom of the batterycases back into the electrolyte. It is bestfor the batteries if the unit is movedenough to mix the electrolyte every fewmonths.


BATTERY TESTING

The BATTERY LEVEL indicators on thecontrol module front panel are all that isrequired to monitor battery charge levelunder normal operating conditions. If abattery problem is suspected, there aresome easy to perform tests that can helpto isolate the problem.

The first step in isolating a battery bankproblem is to measure the battery volt-age under varying conditions using aDigital Multimeter. We need to verify theperformance of the BATTERY LEVELindicators as well as get a more precisemeasurement of battery voltage. If thebattery bank is fully charged and thesolar charger is active, the battery volt-age should measure somewhere be-tween 13.0 and 14.5 Volts. Remember,the voltage reading will be temperaturedependent because of the temperaturecompensation feature of the charge con-trol circuit.

Voltage readings should be as follows:

Temperature Battery Voltage

50 0 F 14.4 Volts70 0 F 14.0 Volts80 0 F 13.7 Volts

100 0 F 13.3 Volts

If voltage readings are different fromthose listed above, batteries should firstbe charged using an external automaticbattery charger and the voltage mea-surements taken again. If the voltagereadings still fail to meet the abovespecifications, further testing of the bat-teries or the solar charging system maybe required.

The condition of the batteries can bechecked using a battery tester or hy-

drometer to determine the specific grav-ity of the electrolyte in each cell. Ahealthy, fully charged battery will pro-duce an electrolyte specific gravity read-ing of 1.225 or greater. If one cell of onebattery yields a reading significantly lessthan 1.225 that battery has a bad celland will adversely effect the performanceof the entire battery bank.

Replace the defective battery with anidentical make and model battery andrerun the battery bank tests.

If the hydrometer test indicates that allbattery cells are healthy, but you stillsuspect a battery bank problem, thenthe next step is to individually load checkeach battery. This will require that thejumper wires that connect all the batter-ies in parallel be removed. Loosen allthe battery terminals and carefully re-move all the jumper wires to isolate allthe batteries. Now using a battery testerapply a heavy load to each battery andcheck the load current and battery volt-age. If the vent caps are removed, ahigh resistance cell can be located byobserving bubbling of the electrolytecaused by overheating of that cell.

A battery with a high resistance cell con-nection will pass all other tests and ap-pear to be healthy when it indeed is not.

Again replace the defective battery andrerun the battery bank tests.

If after conducting all the battery teststhe batteries appear to be all right, butthe unit still fails to provide continuousservice in conditions of adequate sun-light, the power output of the solar arrayshould be checked.


BATTERY CHARGING

The battery bank used on the SILENTSENTINEL has a very high energy stor-age capacity and under normal operat-ing conditions, should never require re-charging. However, if the unit was oper-ating in severely cold conditions or usedin a location where adequate sunlightwas not available; if the LAMP INTEN-SITY control was locked in the HIGHposition for an extended period; or if theunit has been operating under bright nightlighting, such as a street light, prevent-ing the lamp brightness control from dim-ming the lamps at night, the battery bankwill eventually run down and require anextended period in adequate sunlight,preferably with the pattern select switchin the OFF position or charging from anexternal source. This will insure that theunit will provide the best possible per-formance when it is put back into ser-vice.

Although the SILENT SENTINEL isavailable with an optional built in auto-matic battery charger, it is generally rec-ommended that in the event that the bat-tery bank does require recharging thatan external battery charger be used. Forthe few, if any, times that the batterybank needs to be recharged the built incharger seems like an unnecessary ex-pense. In addition, because of the uniquedesign of the charge control circuit in thecontrol module, any commercial auto-matic battery charger can be used torecharge the battery bank without theneed to disconnect any wires or cables.

Simply connect the positive (RED) leadfrom the charger to the positive (POS)terminal of one of the batteries in thebattery bank with the RED jumper at-tached. Then connect the negative(BLACK) lead from the charger to thenegative (NEG) terminal of one of the

batteries in the battery bank with theBLACK jumper attached.

NOTE: Do not connect the chargerleads to the battery terminals withthe jumpers that connect the nega-tive (NEG) terminal of one battery tothe positive (POS) terminal of anotherbattery in the battery bank!

Plug in the charger, switch it on and let itrun to completion. As always, observecorrect voltage polarity!

The battery bank used in the SILENTSENTINEL arrow boards, dependingon the battery configuration, providesanywhere from 260 to 520 Amp Hours ofenergy storage. What this means is thatit takes a significant amount of energy torecharge the battery bank once it be-comes completely discharged. Usingthe following guidelines will help insurethat the battery bank is receiving a fullcharge during a recharge cycle.

BATTERY CHARGER HOURS REQ'D FOROUTPUT CAPACITY FULL CHARGE

20 Amps 18 to 48 hrs40 Amps 9 to 24 hrs60 Amps 6 to 16 hrs

It is also important to keep in mind thatwhen using a line-powered auxiliary bat-tery charger, the BATTERY LEVEL in-dicators on the unit's control panel willnot correctly indicate the state of chargeof the battery bank. The BATTERYLEVEL monitoring and indicator circuitsbuilt into the control module are designedto monitor the state of charge of thebattery bank during charging by the so-lar electric panels. The solar electriccharging system provides a slower re-charge cycle than a line powered chargerand will raise the battery voltage moreslowly and to a lower voltage level.


The solar electric charging system willrecharge the battery bank to a voltage offrom 13.3 to 14.5 Volts depending onthe ambient temperature. The BAT-TERY LEVEL display will indicate aFULL charge whenever the battery volt-age is above 13 Volts. Based on theoutput current range of the solar charger,a battery voltage in excess of 13.0 Voltsindicates a very high to full state ofcharge.

When using a line-powered auxiliary bat-tery charger, however, the high outputcurrent will push the battery voltage over13 Volts within minutes after the start ofthe charge cycle. This does not indicatethat the battery bank is fully charged.The higher voltage indication simplymeans that the battery bank is receivinga charge at a much faster rate than thesolar electric charger can provide. Thiswill result in a much higher battery volt-age, typically 15 Volts or more, duringthe charge cycle, particularly near theend of the recharge cycle when the bat-tery bank is reaching a full state ofcharge.

When using an auxiliary battery charger,always use the state of charge indica-tors on the charger. If no indicators areavailable, use the information on thecharger cycle time chart to determinethe approximate time required for a com-plete charge cycle.

Automatic type battery chargers, the typewe install as optional auxiliary chargers,are ideally suited for this type of applica-tion. They constantly monitor the state ofcharge as well as the rate of charge andwill automatically shut off when the chargecycle is complete. The automatic typechargers will provide precisely the rightamount of charge regardless of the sizeof the battery bank or its state of charge.

Simply connect the charger, plug it in,and let it run to completion.

In an emergency, jumper cables can beused to connect the battery bank to thebattery of a vehicle, with the engine run-ning, to recharge the battery bank. Acharge time of one to two hours willprovide more than enough energy to putthe unit back into service. Incidentally,the unit can be switched on within min-utes of being connected to the vehiclebattery, providing service while it is be-ing recharged.

Another example of the safety, efficiency,and convenience designed and built intoevery SILENT SENTINEL.

When the batteries finally reach the point intheir life cycle that they are unable to effec-tively hold a charge, they will have to bereplaced. The battery compartment is de-signed to accommodate case sizes GC-2batteries. The batteries should be of thedeep cycle variety with a minimum AmpHour capacity of 260 Amp-Hours each.Replace the batteries with an equivalentrating battery to insure that the run-timeperformance originally designed into theunit will not be compromised.

SOLAR ARRAY

The array of solar (photovoltaic) panelsmounted on top of the unit are the prin-ciple source of energy for operation andmaintenance of the battery bank. Nor-mally, the only attention that they de-mand is an occasional cleaning with mildsoap and water.

Whenever the solar array is beingchecked or serviced, make certain thatthe wire terminal screws are tight andthat there is no evidence of corrosion.


In the event that one of the solar panelsshould become damaged, very often theycan be easily repaired. The unbreak-able type of solar panels generally willtolerate a great deal of impact and bend-ing without sustaining any damage.

If the upper surface of one of the solarpanels is severely scratched or punc-tured, the void should be filled in with aclear silicone sealant. The panel willcontinue to function as long as the solarcells are protected from excess mois-ture penetration.

If the aluminum frame in which the pan-els are mounted is twisted or bent, it canbe repaired or replaced without neces-sitating the replacement of the entirepanel.

Disconnect the wires from the solar panelelectrical terminals and remove the dam-aged panel from the solar array mount-ing bars. Depending on which panel isbeing removed, it may be easier to re-move the entire solar array from themounting frame first. Performing solarpanel repairs indoors or out of the pathof direct sunlight will prevent sparkingfrom occurring when wires are connectedor disconnected.

The damaged frame can be removedfrom the panel by removing the screwsfrom the corners of the frame. Replacethe damaged frame members and reas-semble the frame. The repaired solarpanel can now be reinstalled on themounting bars.

Make sure the wires are connected tothe appropriate terminals and securelytightened. Observe correct terminalpolarity. The black wire from the solararray power cable should be connected

to the negative (-) terminal and the whitewire to the positive (+) terminal.

SOLAR ARRAY POWER OUTPUT

If you suspect there is a problem with thesolar array but there is no obvious physi-cal or electrical cause, the power outputfrom the solar array can be easily mea-sured to determine if the array is per-forming up to acceptable standards.

You will need the following items to per-form the power output tests. A multim-eter with DC current capability of 10Amps, three test leads with small alliga-tor clips on each end, and a small piece(one foot square) of cardboard or otherinsulating material.

The unit must be in full sunlight during themiddle of the day to successfully per-form this test.

Remove the fasteners securing the con-trol module. Carefully remove the con-trol module and lay it on the piece ofcardboard insuring that the control mod-ule does not come in contact with anybattery terminals.

Set the multimeter to measure DC cur-rent, 10 Amps or greater.

Refer to the control module circuit boarddiagram in the back of this manual.

Remove the cable which is plugged intoconnector P3 on the control module cir-cuit board. Using a jumper lead, con-nect PIN 2 of the solar array power cableconnector to PIN 2 of connector P3 onthe circuit board. Using another jumperlead, connect the positive lead from themultimeter to PIN 1 of the solar arraypower cable connector. Using the third


jumper lead, connect the negative leadfrom the multimeter to PIN 1 of connec-tor P3 on the control module circuit board.

The SOLAR CHARGER ACTIVE indi-cator should come on at this point. If theindicator does not come on, check themultimeter settings and the test leadconnections.

The multimeter will indicate the amountof current that the solar array is generat-ing. The actual solar array output currentwill vary depending on the amount ofsunlight striking the panel and on thecharge condition of the battery bank.Higher levels of sunlight will, of course,produce higher output current and a dis-charged battery bank will draw morecurrent from the solar array than a fullycharged battery bank.

The current generated by a fully func-tional solar array in good sunlight shouldbe as follows:

50 Watt array - 1 to 2 Amps 75 Watt array - 2 to 3 Amps100 Watt array - 3 to 5 Amps

NOTE: Solar array upper surface mustbe clean for the test results to be valid.If an oily film has built up on the sur-face, it should be cleaned with a com-mercial window cleaning solution.

If the battery bank is fully charged, indi-cated by a FULL display on the BAT-TERY LEVEL indicators, the current out-put from the solar array may switch onand off. This is due to the charge con-troller circuit in the control module sens-ing the state of charge of the batterybank and switching the charging currenton and off as required to maintain thebattery bank at a full charge level.If the current readings obtained during

the solar array test are significantly lowerthan those indicated in the table, one ormore of the solar panels may be defec-tive. If this is the case it will be neces-sary to test the solar panels individually.

Disconnect the solar array power cablefrom the solar array and remove the so-lar array from the solar array mountingframe. Disconnect all of the jumperwires connecting the solar panel electri-cal terminals together. Now measurethe current output from each solar panelby connecting the leads from the multim-eter to the solar panel output terminals.The output current from the solar panelsshould range from 1 Amp on a cloudyday to 3 Amps on bright, sunny summerday. On an average sunny day the outputcurrent should be about 2 to 3 Ampsdepending on the individual solar panelrating.

If the current output from any of the solarpanels is less than that anticipated, thesolar panel is not performing up to re-quired levels and should be replaced.

When the solar array jumper wires andpower cable are being reconnected, besure to observe correct polarity. Alsomake sure that none of the wires orcables are in a position where they mightbe pinched or abraded.

If any of the wire terminals need to bereplaced, be certain to use good qualitytin-plated copper terminals. If any of theterminal screws or lockwashers must bereplaced use stainless steel hardware.

After all testing has been completed,reconnect the solar array power cable toconnector P3 on the control module cir-cuit board and return the control moduleto its position in the battery compart-ment.


POWER CONSUMPTION

A very effective way of determining if theSILENT SENTINEL is operating prop-erly and at peak efficiency is to measurethe current consumption under typicalknown operating conditions. Perform-ing this test will require the same equip-ment used for the solar array power out-put test. This test must be performedindoors, out of direct sunlight, or with thesolar array output cable disconnectedfrom the control module.

Disconnect the wire on the positive (+)terminal on the battery closest to thecontrol module compartment that goesinto the control module compartment.Configure the multimeter for measuringDC current up to 10 Amps. Connect thepositive lead of the multimeter to thepositive terminal of the battery and thenegative lead of the multimeter to ringterminal on the wire that was just re-moved from the battery.

With the pattern select switch in the OFFposition and the SOLAR CHARGER in-dicators off the multimeter should read10 milliamps or .010 Amps.

Now set the pattern select switch to oneof the patterns indicated below and com-pare the multimeter readings to the tablebelow. The meter readings will alternatebetween the value shown in the chartand .050 Amps as the lamps flash onand off. A digital multimeter with a holdfeature will simplify measuring the cur-rent drain. Current values are in Ampsat a battery voltage of 12.5 Volts.

Current readings even slightly differentfrom those listed in the table above canbe an indication of a problem with theunit. If the readings obtained vary morethan 10% from those listed in the tablecheck to make sure that factory speci-fied lamps have been installed in thepanel and that the lamp patterns arebeing displayed correctly. If no obviouscause for the problem is apparent con-sult with factory service personnel forfurther assistance.


The SILENT SENTINEL is designed toprovide the highest level of reliability pos-sible. However, even the best of equipmentwill require service and repair from time totime. It is when the SILENT SENTINELrequires service and repair that the benefitsof the quality of design that goes into eachand every unit becomes apparent. The SI-LENT SENTINEL is designed to be quickly

and easily diagnosed and repaired. Follow-ing the few simple steps outlined below shouldenable you to zero in on the problem and fixit with a minimum of time and effort. After thesource of the problem is located, refer to theappropriate part of the SERVICE & RE-PAIR section of the manual for the recom-mended procedure to solve the problem andget the unit back into the field.
