Depending on circumstances, procedures indicated by WARNING may also be linked to serious results.
In any case, it is important to follow the directions for usage as they are very important for personal safety.
Failure to do so may cause damage to the equipment, or death or severe injury or significant property
damage.
Store this manual in a safe place so that you can take it out and read it whenever necessary.
Always forward it to the end user.
Make sure to have the following safety circuits outside of the PLC to ensure safe
system operation even during external power supply problems or PLC failure.
In case of excessive current of the system for a long time in the output circuit due to
exceeding the rated load current or short circuit of the load, the module may emit
smoke or catch fire, install the safety devices externally such as fuse or circuit
breaker.
Make sure to have the following: an emergency stop circuit, a protection circuit, an
interlock circuit for opposite movements (such as normal vs. reverse rotation), and an
interlock circuit (to prevent damage to the equipment at the upper and lower
positioning limits)
For output signals that may lead to serious accidents, external circuits and
mechanisms should be designed to ensure safe machinery operation in such a case
Note that when the PLC CPU detects an error, all outputs are turned off. External
circuits and mechanisms should be designed to ensure safe machinery operation in
such a case.
Note that when an error occurs in a relay, triac or transistor output device, the output
could be held either on or off.
The PLC is designed to be used indoors and in electrical environment with
overvoltage level Ⅱ. The power system should have lightning protection
devices, to ensure that the lightning overvoltage is not applied to the power
input/ signal input/control output ports to avoid damage to the equipment.
Do not disassemble or modify the PLC. Doing so may cause fire, equipment failures,
or malfunctions.
A warning that an error is likely to occur.
