When you switch on the switch ‘START’ of the control unit, or push the button ‘START’ of the remote control unit, 27V is
supplied to the relay P9 of the board U4. This relay links chain R23-C4 to the base of transistor T4. This chain provides
actuating of the relay P8 for 1-2 seconds for producing a DC signal fro the impulses coming from the camera.
If there are no impulses from the camera, this can be caused by absence of the film or by its break. So, the camera stops after 1-
2 seconds.
If the camera runs correctly, the relay P8 remains in ON state, and feeds 27V to the relay P1 through its pins 22-23 and pin 18
of the connector III7.
Relay P1 feeds the power amplifier through its pins 12-22. To stop the camera, just switch OFF the switch ‘START/STOP’ on
the control unit, or release the ‘START’ button on the camera, or press ‘STOP’ button on the remote control unit.
If you operate the camera from the remote control unit, set the speed selector into ‘REMOTE’ position.
You can run the camera without film during adjusting or maintenance. To do this, press the button B6 ‘LOCK OFF’. In all
other cases this button should be released.
Blocking diodes D1 and D3 protects the camera from wrong polarity.
If polarity is wrong, indicator lamp L1 is off.
Box is connected to the camera through the connector III3.

5.5.4. Electric circuit of the power source unit
Electric circuit of the power source unit is shown on the Figure 8. The power source unit is purposed for powering the camera
with 27
2.7V DC. The power source unit is connected with the control unit by means of the 4-pins connector. Connector Ш1
situated on the power source unit.
