“I pressed the light switch, but the light is still off! What can I do?”
A problem that occurs in almost EVERY household in which a circuit demand switch is active. The problem starts when the lights are converted to modern light technology such as energy-saving lamps or LED.
This “light stays off” scenario is linked to the functional principle of the demand switch. The demand switches check during the day if power is being used and, if not, the connected circuit is deactivated. There is only one type of check source remaining for continuous consumption checking.
A minimum consumption is necessary to determine a power consumption. This was never a problem with the classic light bulb, it needs considerably more energy to switch on. Therefore, it is a matter of a “minimum consumption threshold” that is needed for the demand switch to function. And that is the problem with energy-saving lamps and LEDs.
Base load resistor as an aid for the demand switch!
Both LED and energy-saving lamps are below the minimum threshold of power consumption. For that reason, the demand switch does not recognize the switch being turned on, in other words, the light does not draw enough power and it stays dark.
With this Eltako GLE base load resistor, the “light ON but still OFF” problem is definitively solved.
This base load resistor is a type of brief electrical hurdle or brief power consumption amplifier for energy-saving lamps and LEDs. Turn the light on after installing and the Eltako GLE base load resistor will increase the power consumption for a split second by around 18 watts so the demand switch can easily recognize the light being turned on and release the power (220 volts, 16 amps) into the circuit. The GLE base load resistor becomes lukewarm.
The special thing about this base load resistor is that the benefit of the new energy-saving technology is maintained.
Installation and function of the Eltako GLE base load resistor
- Installation must be parallel to the corresponding consumer for switching on and off to work. This applies to all base loads. This is surprising to many because this normally causes a short circuit.
- Can be installed directly to the consumer, in the switch box (surface or in-wall) or in a junction box.
- Cable length can be shortened for installation.
- The Eltako GLE base load resistor warms up during the operation but does not get hot.
- Can be installed in solid, dry, and timber construction without any problems.
Higher standby loads can affect or prevent the recognition of a base load, such as fluorescent lamps, dimmers and electronic transformers.
- Installation must be done by an electrician or equally-qualified professional!
Our experience with base load resistors
Base load resistors are new to a lot of electricians because they are being faced with the problems of demand switches and energy-saving lamps/LEDs for the first time. Be patient with your electrician.
Contrary to prior resistor solutions, the Eltako GLE does not get hot and as a result, it can be used practically everywhere. In addition, the whole base load resistor is continuously insulated and therefore a simple contact with the power cable is no longer possible.
This Eltako GLE base load resistor makes the power consumption seem like that of a permanent consumer without the load – neither through increased power consumption nor through higher power costs. All of the benefits of energy-saving from the new light technologies are maintained.
Common situation in practice with demand switches
Whoever installs the demand switches should not only check whether a permanent consumer stops an activation but the type of consumer as well. People often complain about demand switches being faulty and return them, even though there are no A fault is a tear or fracture in rocks that moves two rocks or crusts by distances of a few centimeters to a few dozen or even a hundred kilometers..
Among other things, the mistake also lies in the electrician’s lack of knowledge, who ultimately bridge the demand switches again after installing it to “get a grip” on the problem of low-current lamps. Everything seems to work fine, though the resident remains stressed as they cannot check it and therefore trust that everything has been installed correctly. The lack of improvement of one’s health, as a result, is self-explanatory.
Do you check your demand switches regularly?
The demand switches will only help with your health if it is working. For this reason, we automatically put a control light on each demand switches so that the residents can do the checks themselves. You can also buy these separately if you already own a demand switches.
Is an alternative to a demans switches necessary?
The alternative to the demand switches would be to paint and ground the wall with radiation protection paint. This removes existing stress caused by electric fields even better and does not depend on whether or not other consumers are still in or remain in the facility. For example, a fridge or satellite receiver on the other side of the bedroom wall.
Manufacturer information about GLE base load resistor
A base load is used if consumers cannot be recognized because of their capacity, but switching them on should affect the voltage. Base loads must always go into the facility parallel to the corresponding consumer and switched off with it. Higher standby loads can affect or prevent the recognition of a base load. Examples: fluorescent lamps, dimmers and electronic transformers.
GLE PTC base load in a small sleeve with connection cables; can be installed directly into a consumer, switch box or junction box. It is unable to keep the mains disconnection switch turned on without additional consumers.
