PERIODIC MAINTENANCE
The
ALLMAND MESSAGE BOARD has been designed to minimize maintenance. However
it will be necessary to inspect or test the following areas on a periodic basis.
ARRAY MAINTENANCE
1. Clean solar panels.
2. Check solar panels and wiring.
3. Check wiring to ensure that there is no damage caused by normal use, wear and tear, road
vibration, etc.
BATTERY MAINTENANCE
4. Check water level on each cell of the batteries. Top off when necessary using only distilled
water.
5. Check battery condition. Charge when necessary or when not in use.
GENERAL MAINTENANCE
6. Check taillights to ensure proper operation. Also check tongue, safety chains and pins.
7. Check sign panel for proper operation.
8. Check tires and wheel bearings.
9. Check all nuts and bolts for tightness.
ARRAY MAINTENANCE
Examine the entire array for the following:
Examine the top (photosensitive) surface of each module for cleanliness. Any visible accumu-
lation of dirt can impair energy production and should be removed. Use a soft cloth and either
plain water or a solution of mild detergent (such as dishwashing detergent) followed by a rinse
with plain water. Do not spray or direct a solid stream of water at the modules. No abrasive
material should be used in cleaning the modules. It is very important to note that water can
increase the chance of electrical shocks and burning. Care should be taken to use properly
insulated tools and rubber
gloves when cleaning the modules.
Examine all electrical cabling. Make certain that connections are tight at the module junction
boxes, the controller, and the battery bank. Look for any signs of cable breaks and also for
damaged or missing insulation. If any worn or damaged wiring appears likely to interfere with
proper operation now or later, replace the damaged wire.
