Applying 24V voltage to STO1 inputs causes the STO relay to emit a relay ''click'' sound. If there is no sound, then the reason is related to STO1 relay or it's control. | Applying 24V voltage to STO1 inputs causes the STO relay to emit a relay ''click'' sound.

Measuring condition of B3 is possible with multimeter's diode check function. Check all four diodes from the test points marked in the image. Multimeter red lead goes to anode and black to cathode. All diodes should give reading of 0.4 to 0.5 Volts. | Measuring condition of B3 is possible with multimeter's diode check function. Check all four diodes from the test points marked in the image.
