When troubleshooting a pallet lift cylinder that does not extend, what is a sensible next step?

Measuring the supply voltage of sensor 2B2 is a key step when troubleshooting a pallet lift cylinder that does not extend. This action helps ensure that the sensor is receiving the correct voltage necessary for operation. Sensors are critical components in automated systems; they provide feedback to the control logic ( PLC) regarding the position and operational status of equipment.

If the sensor does not receive adequate voltage, it may fail to send the necessary signals to the PLC that activate the cylinder's movement. By checking the supply voltage, you can confirm whether the sensor is functioning properly or if there is an issue with the power supply. This step directly addresses the electrical aspect of the troubleshooting process, ensuring that the system's components are powered correctly before investigating potential mechanical failures or issues with the control logic.
