Preventive maintenance is very important and should be part of any outdated plan, but surprisingly, not everyone can benefit from it. Read about the main tips for reducing downtime.
Ensure that the cooling fan is free of dust and rotates freely on the drive, PLC and cabinet to prevent overheating
Check the status of the backup battery in the PLC and replace it every six months
Backup! Backup! Backup! We all know that important files should be backed up on a PC, so why not keep copies of important drive parameters and PLC programs? Keeping a backup can make it easier to restore and operate when a component fails
Don't let intermittent failures cause major failures. Make sure that the power is off, and then remove the cover to inspect the components for damage. Components such as capacitors will dry out over time. Sending them to North Industries Corporation for full repair can prevent major failures.
Likewise, clean up before annoying errors get worse. Small things like HMI that take longer and longer may not seem like a big deal, but this is another sign that component failure can stop.
Do you have a spare parts plan This is especially important for factory critical parts and obsolete parts. Normally, the loss caused by downtime is more than the loss caused by downtime, therefore, it only makes sense when you have critical downtime in your inventory.
Check the motor. Both over-lubrication and under-lubrication can cause overheating or malfunction. Also pay attention to the bearing, as this is the most common cause of motor failure.
Is your connection close? Check all connections, terminals and cables.
Check the fuse rating and discoloration. Verify the tightness of the fuse holder.
Although it is not a real preventive measure, ensuring that your wiring matches the wiring diagram can save you time and avoid malfunctions.
