BACKGROUND OF THE INVENTION The invention relates to a wiring for manual control with a discontinuous control of electrothermal devices.

Control units for heavy temperature control by discontinuous temperature controllers so that the entire device is activated with the temperature controller by connecting the main switch. When switched off, the entire equipment is put out of operation. Such a plug-in does not permit the control of the connected appliance by the single start-up potentiometer. A disadvantage of such a solution is the operation of the temperature regulator in a compensating conversion with a suppressed range, which the deflection of the meter is significant to the leftmost position. Such a condition, which persists throughout the operation of the hand control, results in overloading of the temperature regulator's own gauge, especially the deformation of the pointer and other parts of the measuring system. As a result, control accuracy is reduced, temperature controllers are prematurely damaged. In addition, it is unnecessary to operate a temperature controller that wears and consumes electricity.

The above mentioned drawbacks are eliminated by the involvement of manual control in discontinuous regulation.

The essence of the invention is that the second supply of the network is connected to the feed-in contact of the switch. Its contact is connected to a temperature controller. The advantage of the proposed connection is the possibility of immediate manual control of the appliance without damaging the temperature controller. 207 074

Claims (1)

207 074 A schematic connection for manual control in a discontinuous control is shown in the accompanying drawings. FIG. 1 shows a connection with an electronic temperature controller and a non-contact thyristor switch; FIG. 2 shows a connection with an electronic temperature controller and an electronic triac power controller. The wiring consists of an electronic power regulator A connected to the power supply; a controlled consumer B connected to a power regulator; control potentiometers C, D, Ep connected to both power regulator and temperature controller; a temperature controller F, a connected power regulator and a section switch as well as a single power supply and a section switch G connected to the second power supply. The connection according to the invention operates in such a way that the temperature switch F is deactivated by the section switch G, the contact of which is in the position indicated in the figures. The control circuit is closed from one control circuit terminal of the power controller A. The control potentiometer D, the connected first break and changeover contact, and the further connected second expander and changeover contacts of the temperature controller F to the control circuit control circuit type A can be manually adjusted by turning the potentiometer slider. Any power of the regulated consumer B without any other intervention. The connection according to the invention can be used for the design of demanding control devices. OBJECT OF THE INVENTION Connecting to a manual control with a discontinuous control by an electronic power regulator, a power supply is connected to it, and a controlled appliance is output, the control potentiometer leads are connected to one common point connected to one pole of the control circuit and the terminals of these control potentiometers are connected to a second common point connected to the second pole of the feeder, forming one control circuit terminal, a single control potentiometer runner connected to one switching contact, a second control potentiometer runner connected to one expansion contact, a third control potentiometer runner it is connected to a second temperature control switch contact or the control potentiometer inlets and runners are connected to one control circuit, the output of one control potentiometer is connected to one switching contact; The connection of the second control potentiometer is connected to one expansion contact, the outlet of the third control potentiometer is connected to a second switching con- trol of the temperature controller, where the second switching contact of the temperature controller is connected to the second terminal of the control circuit of the electronic power regulator and one mains connection is directly connected to the temperature controller. characterized in that the second mains supply (2) is connected to the inlet contact of the section switch (G), its outlet contact being connected to a temperature controller (F). 2 drawings
