How to check the electrical system of the plastic film slitter rewinder

Checking whether the electrical system of the plastic film slitter rewinder is normal can be done from the following aspects:
1. Appearance inspection
Check the electrical cabinet: Check whether the appearance of the electrical cabinet is damaged, deformed or corroded. Whether the cabinet door is closed tightly and the door lock is intact.
Check the circuit: Observe whether the electrical circuit is neat and orderly, and whether there are signs of damage, breakage, wear or burning. Whether the insulation layer of the circuit is intact, whether there is cracking or shedding.
Check the connector: Check whether the electrical connector is tight, loose, oxidized or heated. In particular, the connectors of important equipment such as motors, inverters, and controllers should be checked.

2. Power supply inspection
Check the power supply voltage: Use a multimeter or voltmeter to measure whether the power supply voltage meets the equipment requirements. Generally speaking, the power supply voltage of the equipment should be within ±10% of the rated voltage.
Check the power supply frequency: For equipment using AC power, check whether the power supply frequency meets the requirements. Generally, the AC power supply frequency in my country is 50Hz.
Check the grounding: Check whether the grounding of the equipment is good. The ground resistance can be measured using a ground resistance tester, and the ground resistance should be less than 4 ohms.

3. Motor inspection
Check the appearance of the motor: Check whether the appearance of the motor is damaged, deformed or corroded. Whether the cooling fan of the motor is running normally and whether there is any abnormal sound.
Check the running status of the motor: Start the motor and observe whether the motor runs smoothly and whether there is any abnormal vibration, noise or heating. Tools such as vibration testers and infrared thermometers can be used for detection.
Check the motor parameters: Use a motor parameter tester or inverter and other equipment to check whether the current, voltage, speed and other parameters of the motor are normal. The current of the motor should not exceed the rated current, the voltage should be within the range of ±10% of the rated voltage, and the speed should be consistent with the equipment requirements.

4. Control part inspection
Check the controller: Check whether the display screen of the controller is displayed normally and whether there is any fault code or alarm information. Press each button of the controller to check whether its function is normal.
Check the sensor: Check whether various sensors on the equipment, such as tension sensors, position sensors, speed sensors, etc., are working properly. Tools such as multimeters or oscilloscopes can be used for detection.
Check the actuator: Check whether the various actuators on the equipment, such as solenoid valves, cylinders, motor drivers, etc., are working properly. You can judge by observing whether their movements are accurate and quick, and whether there are abnormal sounds or heating phenomena.

5. Safety device inspection
Check the emergency stop button: Press the emergency stop button to check whether the equipment stops running immediately. After releasing the emergency stop button, whether the equipment can start normally.
Check the safety door switch: Open the safety door of the equipment and check whether the equipment stops running immediately. After closing the safety door, whether the equipment can start normally.
Check other safety devices: Check whether other safety devices on the equipment, such as overload protection, short circuit protection, leakage protection, etc., are working properly. The effectiveness of these safety devices can be checked by simulating fault conditions.
