If the I/O is located at the "ON" position, when switching the "RUN Mode" to the "STOP Mode,"
the system will set the PLC output at the "OFF" position and then all output actions will be
disabled. Please ensure that the external load will not generate hazardous factors during the
aforesaid process.
⚫
If the CPU module stops running due to catastrophic error, please set all of the output points on
the output module at the "OFF" position. The output status will be retained after being set as
the holding-type memory configuration parameters.
⚫
If the status monitoring pages or the parameters are improperly set, it may result in unexpected
action. Even though the status monitoring pages or the parameters are correct, it is also
required to confirm that the controlled system will not be subject to adverse impact before
starting.
⚫
When applying maximum level of voltage or when the power supplied to the operating switch is
interrupted suddenly during the Insulation Strength Test, it may result in the damage of the CPU
module. In this case, please use the variable resistor to increase or reduce the voltage level
gradually.
⚫
Before conducting the Withstand Voltage Test or the Insulation Resistance Test, please separate
the wire grounding terminal of the power module from the functional grounding terminal.
Otherwise, it may result in burning damage to the equipment.
