Battery lock sensor functionality check
1.
Connect the supply voltage bet ween the brown (+) and blue (-) wires.
2.
Measure the supply voltage between the wires. The value should be +24Vdc.
3.
Measure bet ween the blue (-) and black (output) wires on the voltage area. When a supply is connected and there are no metallic objects within the sensing range, the value is approximately 0V. When a metallic object is moved within the sensing range, the value is the same as the supply voltage, i.e. +24Vdc.
4.
If the values do not match the above, replace the sensor.
