PROTECTOR® IV Gauge Face Installation, Operation & Maintenance Manual
Solar Panel Maintenance
The solar panel is designed for trouble-free use and unattended operation. At most sites, rain will keep the
panel surface clean, thus preventing power output degradation. The Lexan sheet is exceptionally resistant
to weathering as it will remain clear and non-yellowing for many years with minimal deterioration. The dirt
accumulation, which may be encountered in heavily populated areas, can be corrected by an occasional
cleaning with mild detergent.
On a yearly basis, as a preventative maintenance procedure, all bolts which fasten the panel should be tightened
to insure continued integrity of the system. All electrical connections in the junction box as well as the voltage
regulator should be inspected for tightness and for corrosion, especially in harsh environments.
As a measure of preventative maintenance, appropriate lightning protection should be installed as part of the
system in areas where lightning activity is a threat. This protection should follow standard railway procedures
and must be installed by the customer. The voltage regulators are equipped with surge arrestors which protect
their circuitry against induced voltages from lightning or other sources,
but not against a direct lightning
strike
.
Distribution Hoses and Wiping Bars
Maintain wiping bar hoses and wiping bars on a weekly basis as follows:
1. Step on the hose, observe the grease as it emerges from the wiping bar.
2.
Look to see that the flow is uniform from the entire length. At any point where the material does not
emerge, there may be a clog.
3. Repeat the above steps at the other bars. If one bar does not produce material there may be:
a) A clog inside the passageways of the wiping bar. Ordinarily, this would be a rare circumstance.
Disassemble that bar and clean all passageways; or
b) A problem with the check valve, located at the center of track distribution piping, between the ball valve
and the distribution hose. Remove and check for clogging.
Recapturing waste material and keeping the site clean will help monitor future wastage and other changes in
the distribution and carry-down process.
Preparing for Winter
In climates where the winter season will affect the operation of the PROTECTOR IV and the unit will experience
very low temperatures the following should be considered.
• Latches- Due to temperature changes, the latches must be adjusted to prevent improper closing of the lids.
Grease hinges and latches to prevent ceasing or breaking.
•
Lid Seals- Seals will be affected by temperature change. If closed on a wet surface the seals may risk
damage in winter and will have to be replaced.
