Definitions

  • the invention relates to a method for carrying out a load detection in an electronic multi-purpose switch, which can be used in the field of building installation technology.
  • Electronic switches of the installation technology contain load switching elements, e.g. Relays or semiconductor switches that can be controlled by electronic means.
  • Electronic shutter switches for example, contain two relays, the associated control device causes only the relay for the up direction or the relay for the down direction can be turned on, but never both relays at the same time, otherwise a connected blind motor could be damaged.
  • Electronic series switches also contain two relays, which may be switched on individually or both at the same time.
  • the two mentioned electronic switches can basically have the same type of control buttons for on-site operation, or even similar connections for a remote control from an extension.
  • EP-A-0827255 a method for carrying out a load detection is known, wherein during a mains half-wave the voltage dropping across a load to be detected and the current flowing through the load are determined. From these values, the load impedance is calculated. Based on a comparison of the determined load impedance with a plurality of predetermined load impedances, a load identification takes place.
  • the invention has for its object to provide a method for performing a load detection in a multi-purpose electronic switch, which can be used either as a series switch or as blind switch.
  • the invention enables rationalization in manufacturing, warehousing, distribution and assembly, since the electronic multi-purpose switch is adapted to automatically check which type of load is connected and to automatically adjust its operation depending on the test result. Device confusion or installation errors are thereby avoided.
  • Fig. 1 shows an electronic multi-purpose switch 1, which has a switching unit 2 with two controllable load switching elements 3, 4.
  • the load switching elements 3, 4 are shown in the drawing as a contact. They are controllable by control means 5, 6, namely a logic unit 5 and an electronic evaluation unit 6.
  • the logic unit 5 may be, for example, an electronic circuit or a microprocessor.
  • a control element 7 with buttons is present.
  • Via control connections 8, 9 is an extension 10, for example, connected via a bus connection. Extension 10 may be, for example, a timer.
  • a power supply 11 is provided for feeding the functional units 2 to 7 of the electronic multi-purpose switch 1. Cable connections and effective directions are indicated by arrows.
  • 14 is a lamp with two in series switching operation switchable lamps shown.
  • 15 a typical blind motor is called, which has a capacitor C.
  • This behavior of the shutter motor 15 is used in electronic multi-purpose switch 1 for load detection. This can be done by the logic unit 5 or the evaluation unit 6 turns on after applying the mains voltage of one of the load switching elements for a duration T of about one second, during which a connected blind motor can move from its end position, if the corresponding up or down direction was controlled.
  • T duration
  • the evaluation unit 6 determines whether the open connection 12 or 13 is connected to the evaluation unit 6. If no reverse voltage is detected, the test procedure is repeated by activating the other direction of movement. If a return voltage is detected in the first or second test step, the evaluation unit 6 sets the operating mode shutter switch on the logic unit 5. For safety reasons, this operating mode is also selected if the test result should not be unique. If no blind motor is connected, the series switch operating mode is set.
  • multi-purpose switch can also be used or adapted for the connection of Venetian blind motors with a different structure and that the test procedure can also be modified accordingly.
