Using a basic timer can be a bit of a mystery for many people. It’s important to understand the basics of how these devices work so that you can use them safely and effectively.
Mechanical
During the industrial revolution, mechanical timers played a major role in allowing machines to operate on timed cycles. They were simple and reliable. They could be used in many different applications. Depending on the model, some of them were hand held, while others mounted on panels. Some mechanical timers were even portable.
Traditionally, a mechanical timer was a small device that used a clockwork to measure the duration of time. However, technology has progressed and electronic timers have become more convenient and less expensive.
In the past, electro-mechanical timers were used in aerospace systems. These were typically combined with electrical relays. They could withstand power surges and could be used to regulate specific machine functions. Moreover, they were also long lasting.
Today, GE offers a wide range of products, including a plug-in mechanical timer. The device is easy to use and perfect for lamps and small appliances. It can also be used with LED bulbs and CFL bulbs. It features a convenient override switch that makes setting the time easy.
Watchdog
Having a watchdog is important for a mission-critical system. In addition to protecting against hardware/software faults, it can also help the system recover from transient failures. Moreover, it may be required by regulatory bodies. Its use can be useful to keep the system from being susceptible to denial of service attacks.
The basic function of a watchdog is to detect and alert the system of a potential failure. A watchdog is typically built into microcontrollers. It is usually disabled by default, however. In some systems, the enabling signal is delayed. This delay allows the computer to boot before the watchdog is enabled.
It is often considered a “must have” in mission-critical systems. Some modern microcontrollers have built-in watchdog timers, making it easier to implement. These timers can be programmable to a specific interval.
Test if it’s got power
Using a voltmeter to test if a basic timer has power is a useful tool. Besides being able to provide you with a watt-second countdown, the meter can also help you determine the voltage of your home’s 110V or 220V AC input. You can even check whether your power is off.
For example, if you have a good transformer, you’ll be able to get a voltage range of 22 to 27VAC, which is more than adequate for a basic 35 minute timer. If the voltmeter reads less than 24V, you’ll know that your timer’s wiring is suspect.
You can also test your timer with a volt meter by crossing terminals L-1 and L-5. Aside from the power, you can also check if a timer has a GFCI protected circuit. These outlets are typically found in bathrooms or kitchens.
GE basic indoor timer
GE basic indoor timers are a great way to automate a single plug-in device, such as a lamp or small appliance. With a simple push of a button, the device is turned on and off. This easy to use timer is compatible with both CFL and LED bulbs, and is perfect for lamps, small appliances, and lights in any room in your home. Designed to be used in place of a standard wall switch, it features an easy-to-read dial that shows the current time of day, as well as a 24-hour clock that displays the time of the next day. It comes with a white wallplate and can be easily installed into any switch box with a neutral wire.
Summary:
In addition to a 24 hour dial, the timer also has a daily on/off cycle, and 30-minute increments. If you want to adjust the times, there are segments on the center of the timer dial that can be pushed in with a pen or pencil. This timer is also very durable, and the sleek white finish will match any decor in your home.
