POINT
*1 Overcurrent protection
The overcurrent proctection device shuts off the 5VDC and/or 24VDC circuit(s) and stops the
system if the current exceeding the specified value flows in the circuit(s).
As this results in voltage drop, the power supply module LED turns OFF or is dimly ON.
After that, eliminate the causes of overcurrent, e.g., insufficient current capacity and short-circuit,
and then start the system.
When the current value has reached the normal value, the initial start-up of the system will be
performed.
*2 Overvoltage protection
The overvoltage protection shuts off the 5VDC circuit and stops the system if the overvoltage of 5.5
to 6.5V is applied to the circuit.
This results in the power supply module LED turning OFF.
When restarting the system, power OFF and ON the input power supply, and the initial start-up of
the system will be performed. If the system is not booted and the LED remains off, this means that
the power supply module has to be replaced.
*3 Allowable momentary power failure period
The programmable controller CPU allowable momentary power failure period varies with the power
supply module used.
In case of the A1S63P power supply module, the allowable momentary power failure period is
defined as the time from when the primary side of the stabilized power supply for supplying 24VDC
to the A1S63P is turned OFF until when the voltage (secondary side) has dropped from 24VDC to
the specified voltage (15.6VDC) or less.
*4 Inrush current
If the power supply module is re-powered ON right after powered OFF (within 5seconds), the inrush
current exceeding the specified value (2ms or less) may be generated. Therefore, make sure to re-
power ON the module 5seconds after power off.
When selecting a fuse or breaker for external circuit, consider the above point as well as blown and
detection characteristics.
