Protect your marine electronic equipment, while detention or stacked

For some reason, when the time comes, it helps to know how protect their marine electronic equipment, while detention or stack your boat. Anyone who has been in electronics for any period of time knows that one of the most common phrases after the discovery of an electronic problem is "that was working when you turn it off." A large percentage of electronic failures occur at the instant of turn. This can be attributed to a number of factors, including exposure to moisture, abnormal voltages, electricity static, and extreme temperatures. When the vessels remained dormant for long periods of time that incidents of electronic equipment failures seem to increase significantly. However, there are steps and precautions that owners, operators and technicians can take that can greatly reduce the potential for equipment failure that often accompany periods of disuse.

Before entering the real electronics might be a good idea to touch something else that directly links on this issue. The battery system needs to be considered when developing a plan for the detention or stack your boat. If you are not going to be in operation (bilge pumps ie, fire systems …) during downtime then you should consider just disconnect the battery completely. Either way, should be fully charged prior to storage and not go more than several months without charge. The best practice is to recharge the batteries before falling below a level of charge 70%. Avoid extreme temperatures and prolonged exposure to moisture. A lead-acid battery with no load that allows the freezing can be damaged irreparably. Be sure to charge the batteries before use. firing up the generator and turn around, while charging the batteries is a bad practice and could result in equipment damage.

In confined spaces on a ship containing the electronics, installing a dehumidifier is an excellent way to control condensation. Not only will it help protect your electronic equipment, but a long way toward controlling corrosion in the wiring and connectors. In small spaces where the installation of a dehumidifier is not possible, use silica gel packs can significantly reduce moisture. Great gel packs are available that actually cover several hundred cubic feet. Placing smaller packages within the radar scanners, TV domes Satellite, and any other enclosed space housing the electronics is a very inexpensive way to help in controlling moisture. As mentioned previously, eliminating 100% humidity is impossible, but the application of each method and tool at your disposable should be a top priority.

Another area of concern is the potential for damage due to static electricity, even the worst kind, a ray. ships and all that stands of these are magnets for static and does take much to cause serious damage to your electronics. There is absolutely nothing you can do to prevent damage in case your boat, or anything holding it so directly, indirectly or even lightning. However, reducing the amount of static buildup on the antennas will reduce the chances of a strike. Even without a flash, simple static buildup on the antennas and cables can cause potentially serious damage to electronic equipment. As with humidity control, take an active role in preventing damage from static electricity and will be much better for him.

Mayor antennas VHF and SSB that are configured in a manner of rudeness are better at standing flat roof. Be sure and adequate security in its "down" position prevent blow around by the wind or disturbed by the rocking of the boat. Disconnect coaxial cable at the end of radio prevent static electricity accumulates in the passage of equipment. Labelling of cables is never a bad idea. What is obvious today may not be as obvious a few months down the road. The development of a method of grounding the cable shield (outer conductor / braid) provides a way of constant barrage of all the electricity that is currently underway to the cable. For those of you who love me and dotting the T intersection, a short in the central conductor of the coaxial cable to the protective earth fell into this category. Obtaining a connector that mates with the one at the end of the cable can short selling land and process much easier. Bonds all electronics ships common ground (water) is also recommended. There is no need to keep your computer running properly, but it does reduce the chances of static-up and may also serve to reduce the paths of eddy currents that can promote electrolysis. metal hulls that this work really easy since almost everything is a good ground. However, non-metallic vessels require considerable effort and attention in the ground. Volumes have been written on this issue so that's where I'm going to leave it for now.

excessive temperatures can be devastating to electronics. Although most of the quality marine electronic equipment manufactured today is designed to withstand the harsh environment, reasonable precautions still make sense. Take measures to avoid exposure to direct sunlight for prolonged periods of time. Block windows and provide shade when needed. If your computer comes with snap in the plastic covers, use them. Most of us have been around electronics enough to understand how damaging heat and exposure prolonged exposure to direct sunlight can be. If you use common sense and do what you can to minimize exposure to extreme temperatures, your electronics (and your pocketbook) will thank you.

Once you are ready to revive the electronics after a long downtime are a few things to consider. It is best to stabilize the situation before returning to the team. Do not turn the air conditioning on a hot summer day or heating in winter and immediately turn on the electronics that are in the same area. This only promotes the condensation that has been trying to avoid. Make sure the batteries Fully charged and visually inspect everything, including the antennas. Once the electronics are turned on, a little extra time for the radios and radar before transmitting. If you disconnected the antenna cables, but decided not low, remember why you did it first. You were trying to keep static electricity from your electronics, so be sure and soil at the end of the cable before reconnecting to discharge any static electricity that may be on the line.

Although the main purpose of this article is for when your boat will be out of service for an extended period of time, some of the practices and procedures given here can be applied to everyday activities, care and maintenance of electronic equipment. Not all failures can be avoided, but with a better understanding on your computer and the application of some relatively simple procedures, you can go a long way toward extending the life of your electronics and saving much money. Smooth Sailing.
