The rear circuit 38 is connected to the second input of the logic element 2I 39, the output of which is the output of the block.

Device control failure mechanism of rotation of the trays of incubators works as follows.

There are the following main malfunctions of the trays turning mechanism: the command unit did not issue the next command to turn the trays after 60 minutes; the command block issued a command, but the turning mechanism did not turn on (one of the limit switches was open, the motor control circuit was faulty), or the turn was not fully completed (the trays were jammed, the protection was triggered); the time for the trays to turn from one extreme position to the other has expired (key is cut off, the coupling is disconnected).

If the rotation mechanism of the trays is intact, the command unit 1 issues a command for 2 motor controls after 60 minutes, which connects the electric motors 3 to the mains. On the secondary windings of the current transformers 4, an alternating voltage arises, which is fed to the inputs of the limiters-shaper 5 constant voltage. The transistor switches 6 are opened and at their output a level of "O" appears, which is fed to the first inputs of the cells 7 of the indication of the malfunction of the rotation mechanism. Simultaneously, the signal from the command unit 1 is fed to the input of the imaging unit 8 pulses. At the output of the pulse driver 8, the level "1" appears briefly, which goes to the installation input of the counter 9, sets it to the zero state. The output of the inverter 10 briefly appears level "O. Triggers 11 and 12 are switched. At the inverse output of trigger 12, a level "O" occurs. Counters 14, 15 are connected, since their installation inputs receive a level of "O" and also blocking the alarm unit 16. At the direct output of the trigger 11, a level "1" is set, which, arriving at the first input of logic element 2I 13, permits the passage of synchronizing pulses from the generator 17 of pulses to the second inputs of the other cells 7 of the indication of the malfunction of the rotation mechanism.

As the trays turn, an accumulation of pulses occurs in the counters 14, 15. The full turn time corresponds to the time TI (fng. 2), and the time to fill the counter

15 T slightly less than a full turn. During the time T, synchronizing pulses arrive at the second inputs of the signaling cells 7 of the signaling device (Fig. 2). The front of each synchronizing pulse initiates the rewriting of information set at the information input of the trigger 24. When the trays are functioning properly, the information input of the trigger 24 for the turn time T is set to "O, therefore switching the trigger 24

5 does not occur. After filling the counter 15, the level “1” appears at its output, and the level “O” appears at the output of the inverter 19. The trigger 11 switches and at its direct output a level of "O" appears, which, when entered into the logic element 2I 13, blocks the passage of synchronizing pulses to the inputs of the display cells 7. After filling the counter 14, the filling time of which Tz is slightly longer than the full turn time (Fig. 2), the first level appears at level 1, which, arriving at the first input of logic element 2I 18, permits the passage of synchronizing pulses to the third inputs of the cells 7 fault indications

0 turning mechanism. By this time, the turn of the trays was over and the level 25 set at the information input of the trigger 25, so that the flip-flop of the trigger 25 does not change. As the counter 14 is further filled, the level “1” arises at its second output, and the level “O” appears at the output of the inverter 20. Trigger 12 is switched and at its inverse output the level “1. Counters 14, 15 are reset. Device comes to original

0 state.

If the trays were jammed and the automatic switch has disconnected the motor from the mains before a full turn or the turn mechanism is not turned on, the first input of the display 7 of the failed incubator indication is set to level "1. The front of the synchronization pulse switches the trigger 24 of the indication 7 cells 7 and at its inverse output a level "O (Fig. 3)" appears. LED 27 is lit, a fault is displayed. Trays are not wrapped. At the direct output of the trigger 24, the level “1” appears, which through the diode element OR 29 is fed to the first input of the signaling unit 16. At the output of the transistor switch 30 of the signaling unit 16, a level “O” arises, and at the output of the inverter 31 - a level “1. After the end of the monitoring cycle on wto0

The signal input of the alarm unit 16 sets the level “1, while the output of the log of the SCH element 2I 32 results in the level“ 1. The actuation of the actuating element 33, which connects the audible alarm. The attendant reads information about the malfunction of the mechanism of rotation of the incubator trays and, by operating the button 37 of the reset unit 23, brings the display cells 7 and the alarm unit 16 back to its original state. When you press the button 37 to the first input of the logic element 2 and 39 receives the level of "O. At this moment at the second input of the logic element 2I 39 there is a level “1. At the output of logic element 2 and 39, a level "O" appears, which, through the disconnecting contact of the switch 26 of the display 7, arriving at the installation inputs of the flip-flops 24, 25, sets them to their initial state. B. Uc 23 of the reset, in addition, leads the display cells 7, 22 and the alarm unit 16 to the initial state when the power supply unit of the device is turned on.

If the time of rotation of the trays from one extreme position to another has expired, then at the first input of the bad 7 incubator indication 7, the level “6. The front of the synchronization pulse switches the trigger of the 25th display unit 7, and the level "O (Fig. 4)" appears at its direct output. LED 28 is on, indicating a malfunction. "Turning time overdue. At the inverse output of the trigger 25 occurs level "1, which through the diode element OR 29 is fed to the first input of the block 16 alarm. Then the device works in the same way as when trays are jammed.

If the command block 1 is faulty, then after 60 minutes the counter 9 overflows, and the level “1” appears at its output, and the level “O” appears at the output of the inverter 21. The flip-flop 34 of the indication cells 22 is switched, and at its inverse output a level “O.” occurs. LED 35 is on, indicating a fault. The fault unit is defective. At the direct output of the trigger 34, the level “1” appears, which through the diode 36 enters the first input of the signaling unit 16, causing it to be triggered.

Thus, supplying the device with cells indicating the malfunction of the rotation mechanism according to the number of controlled objects, the cell indicating the malfunction of the command block, the reset unit, the second trigger, the second logic element 2I and the third and fourth inverters allowed KOHipo.ib Mt xaiUMMa noixjfxjra of several incubators using

one device, as well as to indicate the cause of the accident when a malfunction is detected in the mechanism for turning the trays.

The economic effect from the use of the device is due to the reduction of operating costs and capital investments.
