Component Placement Diagram............................................................. Drawing A-69945 Daktronics displays are built for long life and require little maintenance. However, from time to time, certain display components will need replacing. The Replacement Parts List in Section 12.1 provides the names and numbers of components that may need to be ordered during the life of the display. Following the Replacement Parts List is the Daktronics Exchange and Repair and Return Programs in Section 12.2. Refer to these instructions if any display component needs replacing or repairing.

1.1 Safety Precautions Important Safeguards:

1. Read and understand these instructions before installing. 2. Disconnect the power when servicing the display. 3. Do not modify the display structure or attach any panels or coverings to the

display without the written consent of Daktronics. Doing so will render the warranty null and void.

1.2 Network Concepts The concept of using LED displays as cost effective, high impact method of communication is rapidly growing throughout many industries and businesses. The reasons for their growth are many, but the need for additional features and complexity of multiple display installations has emerged. Daktronics display systems have been designed to meet these needs.

Cellular Modem Network The cellular modem is a standard communication interface that utilizes your local provider’s communication network and then converts the signal to RS232 to communicate with the display's controller. The provider assigns a phone number to each modem, thus enabling the modems to communicate between the controller and the display.

Section 5: Battery Maintenance

For your safety, always wear protective clothing, gloves, and goggles when handling or charging batteries.

5.1 Testing Visual inspection alone is not sufficient to determine the overall health of the battery. Both open-circuit voltage and specific gravity test readings can give an adequate indication of the battery’s charge level, age and health. Routine voltage and gravity checks not only show the state of charge, but also help spot signs of improper care (such as undercharging and over-watering) and locate a bad or weak battery. The Specific Gravity tests should be preformed routinely to ensure maximum efficiency of the battery. Each battery contains three cells with a white cell cap. Each cell needs to undergo gravity testing to ensure adequate current levels are being maintained. Use a hydrometer to take accurate readings. The following steps outline the procedure for the specific gravity test.

Specific Gravity Tests (Flooded batteries only) 1. To remove the cap, turn counter-clock wise ¼ turn and pull. 2. Fill and drain the hydrometer 2 to 4 times before taking a reading 3. The hydrometer reading will measure the electrolytes in the battery 4. The float inside of the hydrometer details the strength and quantity of the

electrolytes in the fluid 5. Take a reading, record it, and return the fluid from the hydrometer back to

the cell 6. Check all cells of every battery

The readings should be at or above the factory specification of 1.277 ± .007 (the green zone on the hydrometer scale). If any specific gravity readings register low, then follow the steps below.

1. Disconnect the battery from the circuit 2. Charge the battery 3. Repeat the steps above to test the electrolyte levels

If after repeating the steps, the battery is still not adequate, contact your Daktronics Representative for further options or to replace the battery completely.

Open-Circuit Voltage Test For accurate voltage readings, batteries must remain idle (no charging, no discharging) for at least 6 hrs, preferably 24 hrs.

1. Ensure that the charger is not connected to the AC outlet 2. Disconnect all loads from the batteries by removing the main fuse in the

battery box 3. Measure the voltage using a DC voltmeter 4. Check the state of charge with Table 1 5. Charge the battery if it registers 0% to 70% charged

If battery registers below the Table 1 values, the following conditions may exist:

1. The battery was left in a state of discharge too long 2. The battery has a bad cell

Batteries in these conditions should be taken to a specialist for further evaluation or properly disposed of.

5.2 Watering Flooded batteries need water. More importantly, watering must be done at the right time and in the right amount or else the battery’s performance and longevity will be reduced. Water should always be added after fully charging the battery. Prior to charging, there should be enough water to cover the plates. If the battery has been discharged fully or partially, the water level should also fully cover the plates. Keeping the water at the correct level after a full charge will prevent having water level problems at a different charge level. Depending on the local climate, charging methods, application, and other variables, it is recommended that batteries be checked once a month until you get a feel for how thirsty your batteries are.

Important things to remember:

1. Do not expose the plates to air. This will damage (corrode) the plates 2. Do not fill the water level in the filling well to the cap. This most likely will

cause the battery to overflow acid, consequently losing capacity and causing the battery to corrode.

3. Do not use water with a high mineral content. Use distilled or de-ionized water only

4. Avoid skin contact as the electrolyte solution is a combination of acid and water.

To water a battery:

1. Open the vent caps and look inside the fill wells 2. Check electrolyte level; the minimum level is at the top of the plates 3. If necessary add just enough water to cover the plates at this time 4. Put batteries on a complete charge before adding any additional water 5. Once charging is completed, open the vent caps and look inside the fill

wells 6. Add water until the electrolyte level is 1/8" below the bottom of the fill well 7. A piece of rubber can be used safely as a dipstick to help determine this

level 8. Clean, replace, and tighten all vent caps

Battery Maintenance

5-4

5.3 Cleaning When cleaning the battery, do not allow any cleaning solution, or other foreign matter to get inside the battery.

1. Check that all vent caps are tightly in place 2. Clean the battery top with a cloth or brush and a solution of baking soda

and water 3. Rinse with water and dry with a clean cloth 4. Clean and tighten ALL battery terminals 5. Clean terminals will have a bright metallic shine 6. Thinly coat terminals with petroleum jelly (Vaseline) or an anti corrosion

compound to prevent corrosion 7. Keep the area around batteries clean and dry

5.4 Storing the Trailer There are different winter storage conditions for a trailer and specific steps that must be performed. Regardless of the condition, routine maintenance has to be performed on the batteries. The trailer should rest on its stabilized jacks. Outdoor storage with available 110 VAC outlets

1. Perform maintenance on the batteries 2. Make sure the solar panels are at a 45° (facing the rear of the sign)

in order to avoid dust or snow accumulation on the panels 3. The power switch has to be set to “OFF” 4. Plug the PVMS into a 110 VAC outlet. A maximum of two PVMS can

be plugged per 15A circuit 5. Perform a routine maintenance on batteries once a month

Outdoors storage without any available AC power

1. Perform a maintenance on the batteries 2. Make sure the solar panels are at a 45° (facing the rear of the sign) in order

to avoid dust or snow accumulation on the panels 3. The power switch has to be set to “OFF”. Since the trailer is not working,

the solar panel should be enough to recharge the batteries 4. Perform a routine maintenance on batteries once a month

Removing the batteries prior to storing the trailer

1. Perform a maintenance on the batteries 2. Make sure the solar panels are at a 45° (facing the rear of the sign) in order

to avoid dust or snow accumulation on the panels 3. The power switch has to be set to “OFF” 4. Remove the main fuse 5. Unplug all batteries and remove them from the battery cabinet 6. Store the batteries into a dry and cool location 5°C to 10°C (41°F to 50°F)

7. Store batteries on It is preferable not to store batteries on a concrete floor. Daktronics recommends using wood or plastic pallets

8. Perform a routine maintenance on batteries once a month 9. If the batteries are lower then recommended power, recharge the batteries

using a 6V charger or connect two batteries in series and charge both at the time (refer to Figure 11)

Figure 11: Batteries in series charging with a 12 VDC Charger

At the beginning of the season

1. Reinstall and reconnect the batteries 2. Perform cleaning of the batteries 3. Perform routine maintenance on the batteries

Make sure batteries are recharged for 48 hours before using the trailer

5.5 Battery Charging Time A jumper (RJ11 connector and short wire) is installed on the charger. This jumper is will set the battery-charging mode to a fast charge. When the jumper is absent the battery will charge in float voltage mode. The fast charge mode is used when the batteries are low and the unit is needed soon. In fast mode, the unit should be connected for a maximum period of 48 hours. Prevent overcharging the batteries. Overcharging causes excessive gassing (water breakdown), heat buildup, and battery aging.

Figure 13: Battery Charger

If the unit will be left connected for a long period of time (a couple of weeks), the jumper must be removed and the charger set to float charge to ensure the batteries charged at approximately 80% of the full charge to avoid damaging the batteries. As illustrated in Figure 13, install the jumper (supplied with the charger) to select the fast charge mode. Remove the jumper for float voltage mode.

5.6 Battery Operation in Cold Climates The efficiency of a battery will vary greatly with cold temperatures. Table 2 provides a guide of battery efficiency at different temperatures.

Section 6: Sign Setup

Before beginning the setup procedure, visually inspect the sign. Check for any damage to the sign that may have occurred during towing.

6.1 Trailer Perform the following steps in order to ensure the proper immobilization of the trailer during use. Note: These instructions provide the sign with the maximum wind load capability possible. In order to achieve the maximum wind load capacity, Daktronics recommends that the sign be rotated 90 degrees in either direction of the stored position when in use along a roadside. This means that the trailer will be parallel to the road and the sign is rotated to be perpendicular with the road.

Section 7: On Board Equipment Operation

The VP-1000 variable message trailer mounted sign is highly versatile, especially for temporary setup far from AC power. The sign is powered by 12 VDC batteries that are maintained charged by the solar panel located on top of the sign. The VP-1000 unit can be programmed using a computer via the RS232 link for full control of the sign, or with the use of a keyboard and a small LCD sign for quick message edition features and limited control.

7.1 Sign Menu Use this menu to control the starting and stopping of a sign message. It also addresses how to control the brightness of the sign. When the sign is first powered up the LCD display will show information regarding the sign model and the firmware version running it. You may choose a language preference at this time. English is the default language.

7.2 Local keyboard and sign The sign can be programmed directly on site when a communication link is not available or not desired. The sign can be configured in three different ways:

• Using the built-in console, consisting of a 16-key membrane type keyboard

and companion 4 x 10 character LCD display • Connecting a standard PC type keyboard (AT or PS2) and using the 4 x 10

character LCD display • Connecting a portable PC type computer equipped with a standard RS-232

serial communication port

To assist the personnel on site, the following hardware is supplied with each portable variable message sign: One full size PS2 keyboard, one AT/PS2 keyboard adapter and one DB9F to DB9F serial communication cable. A CD containing the Vanguard® application is also included with the sign.

This section provides all of the necessary information to assist the operator in configuring the S-variable sign locally using the 16-key membrane type keyboard and companion 4 x 10 LCD display as well as using a standard PC type keyboard.

7.3 Operator Login Local configuration of the portable variable sign can be easily accomplished by simply following the procedure described below:

1. Locating the control box of the sign. All of the electronic modules are

housed inside this metal enclosure located on the right side of the sign (non traffic side).

2. Removing the padlock (if applicable) located on the left side of the enclosure (a key is necessary to perform this step if a padlock is installed) and opening the cover.

3. Removing the PC type PS2 keyboard from its shipping box and connecting the keyboard to the connector labelled “KEYBOARD” (it may be necessary to remove the AT/PS2 keyboard adapter prior to connecting the keyboard).

4. Powering the sign by placing the ON/OFF toggle switch to the ON position.

At this point, the following message should be displayed for approximately 40 seconds on the 4 x 10 LCD sign:

Section 8: Solar Power Principals

8.1 Understanding your solar powered sign Your solar powered sign has been designed to operate without battery recharging from the month of March to October. Outside these periods, because of lower solar energy input and lower temperatures causing the batteries to lower their capacity, solar signs will have to be recharged from time to time. The following sections describe in detail the different aspects of these features and their limitations.

8.2 Insolation Insolation or sunlight intensity is measured in equivalent full sun hours. One hour of maximum, or 100% sunshine received by a solar panel equals one equivalent full sun hour. Even though the sun may be above the horizon for 14 hours a day, this may only result in six hours of equivalent full sun. There are two main reasons. One is reflection due to a high angle of the sun in relationship to your solar array. The second is also due to the high angle and the amount of the earth's atmosphere the light is passing through. When the sun is straight overhead the light is passing through the least amount of atmosphere. Early or late in the day the sunlight is passing through much more of the atmosphere due to its position in the sky. Sun tracking devices are available and can help reduce reflectance, but cannot help with the increased atmosphere in the sun's path.

Because of these factors the most productive hours of sunlight are from 9:00 a.m. to 3:00 p.m. around solar noon (solar south). This is different than 12:00 noon. Before and after these times power is being produced, but at much lower levels. When we size solar panels for a solar power system, we take these equivalent full sun hour figures per day and average them over a given period.

In most locations in the United States winter produces the least sunlight because of shorter days and increased cloud cover, as well as the sun's lower position in the sky. Usually, we work with a yearly average, a June - July average when insolation is highest, and a December - January average when insolation is lowest.


8-1


8-2

The diagram above illustrates the path of the sun over varying seasons. Remember when selecting a site for your solar power panels to pick a spot that is clear of shade from a minimum of 10 A.M. to 2 P.M. on December 21st. Even a limb from a deciduous tree will substantially reduce power output. Many solar sites are quite uncomplicated in terms of shading and aspect. You may already have a good idea of where the sun appears in the morning and disappears in the evening, as well as how low it swings in the winter sky. If your site is partially shaded, it may be necessary to determine exactly where the best placement of solar panels will be. If you need a more sophisticated site analysis, please contact us. We also have world-wide isolation data as well as more local data that can be useful for your particular location located in appendix A.

8.3 Solar power batteries Deep cycle batteries used in solar power systems are designed to be discharged and then re-charged hundreds or thousands of times. These batteries are rated in Amp Hours (ah) - usually at 20 hours and 100 hours. Simply stated, amp hours refers to the amount of current - in amps - which can be supplied by the battery over the period of hours. For example, a 350ah battery could supply 17.5 continuous amps over 20 hours or 35 continuous amps for 10 hours. To quickly express the total watts potentially available in a 6 volt 360ah battery; 360ah times the nominal 6 volts equals 2160 watts or 2.16kWh (kilowatt-hours). Like solar panels, batteries are wired in series and/or parallel to increase voltage to the desired level and increase amp hours. A battery in a solar power system should has sufficient amp hour capacity to supply needed power during the longest expected period "no sun" or extremely cloudy conditions. A lead-acid battery should be sized at least 20% larger than this amount. If there is a source of back-up power, such as a standby generator along with a battery charger, the battery bank does not have to be sized for worst case weather conditions. The size of the battery bank required will depend on the storage capacity required, the maximum discharge rate, the maximum charge rate, and the minimum temperature at which the batteries will be used. When planning a power system, all of these factors are looked at, and the one requiring the largest capacity will dictate battery size. One of the biggest mistakes made by those just starting out is not understanding the relationship between amps and amp-hour requirements of 120 volt AC items versus the effects on their DC low voltage batteries. For example, say you have a 24 volt nominal system and an inverter powering a load of 3 amps, 120VAC, which has a duty cycle of 4 hours per day. You would have a 12 amp hour load (3A X 4 hrs=12 ah). However, in order to determine the true drain on your batteries you have to divide your nominal battery voltage (24v) into the voltage of the load (120v), which is 5, and then multiply this times your 120vac amp hours (5 x 12 ah). So in this case the calculation would be 60 amp hours drained from your batteries - not the 12 ah. Another simple way is to take the total watt-hours of your 120VAC device and divide by nominal system voltage. Using the above example; 3 amps x 120 volts x 4 hours = 1440 watt-hours divided by 24 DC volts = 60 amp hours.

Lead-acid batteries are the most common in PV systems because their initial cost is lower and because they are readily available nearly everywhere in the world. There are many different sizes and designs of lead-acid batteries, but the most important designation is that they are deep cycle batteries.

Lead-acid battery divider which corresponds to the battery's wintertime average ambient temperature:

Battery Temperature Multiplier

80°F/26.7°C 1.00 70°F/21.2°C 1.04 60°F/15.6°C 1.11 50°F/10.0°C 1.19 40°F/4.4°C 1.30 30°F/-1.1°C 1.40 20°F/-6.7°C 1.59

8.4 Solar Power Charge Controller A charge controller monitors the battery's state-of-charge to insure that when the battery needs charge-current it gets it, and also insures the battery isn't over-charged. Connecting a solar panel to a battery without a regulator seriously risks damaging the battery and potentially causing a safety concern. Charge controllers (or often called charge regulator) are rated based on the amount of amperage they can process from a solar array. If a controller is rated at 20 amps it means that you can connect up to 20 amps of solar panel output current to this one controller. The most advanced charge controllers utilize a charging principal referred to as Pulse-Width-Modulation (PWM) - which insures the most efficient battery charging and extends the life of the battery. Many charge controllers also offer Low Voltage Disconnect (LVD) and Battery Temperature Compensation (BTC) as an optional feature. The LVD feature permits connecting loads to the LVD terminals which are then voltage sensitive. If the battery voltage drops too far the loads are disconnected - preventing potential damage to both the battery and the loads. BTC adjusts the charge rate based on the temperature of the battery since batteries are sensitive to temperature variations above and below about 75 F degrees.

Maintenance Schedule

10-1

Section 10: Maintenance Schedule

The service intervals listed in this section are only recommendations. These service intervals should be adjusted, if necessary, and adapted to specific operating conditions. Contact Daktronics for maintenance schedule recommendations adapted to specific operating conditions.

Sign Cabinet Inspection At least once a year:

• Check for evidence of water intrusion in the sign, i.e. water stain marks. • Check for any leaks that may have developed. Seal them with a silicone

sealant or any other quality sealer. • Inspect all door gaskets for tears, missing pieces, etc. Repair if necessary. • Check the drain holes in the bottom of the cabinet and the bottom of the

window retainer to ensure they are unobstructed.

Structural Inspection At least once a year:

• Inspect the mounting structure thoroughly for signs of corrosion, loose

bolts, and overall stability.

Face Panel Cleaning Clean the face panels as necessary. Clean the inside and outside with a wet cloth, wipe with a dry cloth. Using anti-static polycarbonate cleaner is highly recommended and will yield the best long-term results.

10.1 Routine/Preventative Maintenance Checklist The following gives a listing of the components and the descriptions of the steps that need to be taken to ensure that the display remains in proper working condition. Tire Pressure: Read the manufacturer's specification for recommended air pressure. This information is located on the sidewall of the tire. Hydraulic Fluid: Fill the pump until it is ¾ full (about one inch (1") from the top of the tank). Use standard hydraulic oil. Note Make sure that the sign is in the lowered position when filling with hydraulic fluid to prevent overflowing. The pump is located under the large door of the battery compartment

Battery Acid Level: Fill the batteries with distilled water until you can see fluid. Remove the plastic safety sheet over all of the batteries. Remove the battery caps and fill with fluid. Replace plastic safety sheet when finished.

Battery Charge: Charge display for 48 hours before every trip. This ensures that the display is fully charged no matter what the conditions are when reaching the installation site. Trailer Lights: Test the trailer electrical system by connecting it to the towing vehicle and actually testing each light. (Clearance, brake lights, flashers, etc.). Clean Solar Panels: Clean the solar panel faces with water or a non-abrasive chemical. Use a type of cloth that will not scratch the panels. Clean Display Face: Same instructions as above, apply to the display area. Water Intrusion Inspection: Check that all seals on the display are tight. Make sure that the drain holes are clear and open. Check for evidence of water and where it might have come from if there is. Tire Wear: Check the tread on the tire. Make sure that the wear is even, no belts are showing, and that there is an adequate tread on the tire. Brakes:

Every month: Check that the fluid on the emergency brake is full. Use a standard DOT 3 brake fluid.

Annually: Take the trailer to a certified mechanic to inspect the brake pads. Lug Nuts: Check to make sure that the lug nuts are tight. Display Latch: Make sure that all (5) five latches are able to latch and hold the face panel light.
