Product details:

PLC control system daily maintenance and maintenance is relatively simple, mainly replace fuse and lithium battery, basically no other vulnerable components.
Because the random access memory (RAM), counter and auxiliary relay with maintenance function are protected by lithium battery.
The life of lithium battery is about 5 years. When the voltage of lithium battery gradually decreases to a certain extent,
the battery voltage on the basic unit of PLC falls to the indicator light,
prompting the user to pay attention to the program supported by lithium battery can be retained for about a week.
The battery must be replaced as part of routine maintenance.
The steps to replace the lithium battery are as follows:
Before disassembly, the PLC should be energized for more than 15 seconds (so that the capacitor as a backup power supply of memory can be charged,
after the lithium battery is disconnected, the capacitor can do short power supply to PLC, in order to protect the RAM information not lost);
Disconnect the AC power supply of PLC;Open the battery cover of the basic unit;
Remove the old battery and install the new battery;Cover the battery cover.
The battery replacement time should be as short as possible, not more than 3 minutes.
If too much time passes, the program in RAM will disappear.
In addition, be careful to replace the fuse with the specified model product. The I/O module needs to be replaced
To replace a module, the user should ensure that the installed module is of the same type.
Some I/O systems allow module replacement while live, while others require a power cut. If the problem is resolved after replacement,
but the failure occurs after a relatively short time, then the user should check the inductive load that can produce voltage and may need to suppress its current spikes externally.
If the fuse is easily blown after replacement, it is possible that the output current of the module exceeds the limit, or the output device is shorted.
PLC fault diagnosis is a very important problem, is to ensure the PLC control system normal and reliable operation of the key.
The common fault diagnosis methods are discussed in this paper. In the actual work process, should take full account of all kinds of adverse factors to PLC,
regular inspection and daily maintenance, to ensure the PLC control system safe and reliable operation.
