Viitor Vtnálezu LOSÁK DUŠAN, BRATISLAVA (51) Universal connection of temperature controller 1

BACKGROUND OF THE INVENTION The present invention relates to a universal connection of a temperature regulator, which relies on a continuous continuous temperature control.

Direct electronic continuous temperature controllers with proportional transmission are used for long-term, demanding temperature control of electrothermal devices. The disadvantage of such a control is the considerable overheating of the desired flow temperature. Indirect-electronic non-continuous temperature controllers with proportional and derivative transfer reduce the total heating at start-up, the disadvantage of which is a greater demand variation in the temperature and considerable laundry impacts to the heating coil, which are prematurely damaged. This is particularly noticeable at temperatures above 1000 K and higher output devices. Taking advantage of the types of regulators would mean using two temperature controllers. On start-up, an indirect electronic discontinuous controller would operate, and in a further operation this would be shut down and an indirect electronic continuous controller would be put into operation. Such a solution of using two separate temperature controllers is costly, volume increases weight and demands on both professional and labor. The aforementioned drawbacks of long-term, uncontrolled temperature control during start-up with the nominal variation of the desired temperature in conjunction with the automation process allow the invention to be connected.

The essence of the invention is that one pole of the output of the measuring amplifier, indirectly 207 078

Claims (1)

The electronic discrete temperature controller 207 078 is routed to the first separate output terminal and the second separate output terminal is connected to the frame. The advantage of the connection is a simple, inexpensive control device suitable for combined control. In the accompanying drawing, a block connection of an indirect electronic discontinuous temperature controller with an output for combined control is shown. The connection consists of a meter 1 connected to a thermocouple and a measurement amplifier; a thermocouple 2 connected to a measurement amplifier; the measuring amplifier 2 of the connected frame and the output terminal; a gauge of the control deviation 4 connected to the measuring amplifier and the frame; sensitivity potentiometer% attached to a skeleton control deviation meter; a three-position flip-flop 6 connected to both the sensitivity potentiometer and the poor-binding potentiometer; poor bonding potentiometer 2 attached to poor bonding member; a member liable to be improperly bound 8, attached to the wand; a power supply 2 connected to the meter, a measuring amplifier and a flip-flop and output terminals 10 connected to relay contacts, frame and output of the amplifier. The wiring according to the invention is used in such a way that during the start-up the individual set outputs from the non-contact thyristor switch, which are connected to the controlled consumers according to the positions of the relay contacts, are connected to the output terminals of the temperature controller and up to d. The setpoint temperature is set at least to the controller's poor link sensitivity. The F6-water connections to the controller terminals up to d are disconnected and the control circuit of the contactless thyristor switch is connected to the temperature controller terminals e and fsa. In this way, the connected loads are connected to the controlled appliances corresponding to the desired temperature. The controller can even compensate for the temperature by increasing or decreasing the power consumption by this change.
