I The invention relates to automation, a molset can be used to determine the efficiency of equipment and control personnel and is additional to aut. EV, W 168989,

The purpose of the invention is to expand the functionality of the device by introducing an audible start signal into it simply and the light indication of the causes is simple.

The drawing shows a block diagram of the device.

The device contains the first 1, second 2 and third 3 resistors, first 4, second 5 and third 6 sensors first 7, second 8, third 9, fourth Tbse 10 and fifth 11 diodes, self-recording current meter 12, source 13 nap For example, the keys 14 and the resistors 15 are simply equipment. In addition, the device contains a voltage converter 6 in the code.

memory block 17, block And 18 elements,

display unit 19, pulse generator 20, element OR 21, buzzer 22 and key 23

The values of resistors 1-3 and 15 are chosen so that with any combination of sensors 4-6 turned on, the current flowing through resistors 1-3 is less than the current flowing through resistors 15 when the upper key 14 is closed,

The device works as follows.

With the de-energized 151X sensors 4-6, the self-recording current meter 12 registers zero current on the chart tape. The inclusion of sensors 4-6, each of which corresponds to one of the operating modes of the monitored equipment, causes current to flow through the resistors 1 to 3 recorded by the current recorder 12. The length of the recording on the chart tape corresponds to the duration of the operation mode, and mode switching is indicated by changes in current levels.

In any mode of operation of the monitored equipment, the current flowing through the self-pinging current meter 12 does not create a voltage drop on its first input terminal sufficient for triggering the first discharge of a 16 "converter

w, 1. If it is necessary to note the reason simply, the operator briefly closes the corresponding key 14. In this case, the self-recording current meter 12 records a pulse on the chart tape, the value of which depends on the number of resistors 15 connected to 1 SUP 4.

The operation of the alarm and indication is considered -1 when the third is closed on top of the key 14.

In this voltage drop, the input voltage of the converter 16 is sufficient to trigger the third bit of the converter 16. Signal 1 appears only on the third bus of converter 16. Similarly, converter 16 produces a signal only on one output when any other switch 14 is closed. Triggers The 17 memories are automatically reset when the voltage source 13 is turned on. The corresponding pv; cb is not shown in the drawing, since the methods of installation in O-triggers when the power is turned on are widely known.

The signal from the third output of the converter 16. enters the input of the block

17 and flips the corresponding trigger to one state. The signal from the output of this trigger is fed to the input of the OR element, which turns on the buzzer 22, This provides an audible signaling of the beginning of a simple process. Simultaneously, the signal from the output of block 17 permits the element AND block

18 skip pulse generator 20, continuously oscillating with a frequency of 2-5 Hz. Periodically opening the element AND block 17 provides a light indication of the corresponding cause simply by a signal lamp in block 9 "

Similarly, the device works when any other key 14 is closed, and the alarm and indication also work after the key is unlocked. With the successive closure of two or more keys 14, the light indication provides an indication of each of the causes simply. The acoustic signaling and the light indication are reset by closing the key 23, through which the pulses of the generator 20 pass to the reset input of the unit 17 and reset its triggers to the zero state.

The time is simple or the work of the controlled equipment in each pc31

The press is determined by a chart tape.
